1. RAy – Microwave Link

RAy Microwave link RAy is designed as high-speed point-to-point wireless bridge for data transmission under the latest requirements of modern wireless transmission equipment. It is built on a platform with a modern component base.

Ray works with ethernet interface and can be used in backhaul networks as well as a last-mile terminal.The design of microwave link RAy reflects effort on meeting the strictest criteria ETSI standards, particularly for durability against interference, high receiver sensitivity and high output power to achieve maximum link distance. Native gigabit Ethernet interface is able to cope with full speed user data throughput at low latency. High availability of the link (up to 99.999%) is able to be achieved with using hitless Adaptive coding and modulation.

The link properties can be summarised as:

• High data throughput

• Spectrum effeciency

• Robustness

• Security - cofiguration via http, https, ssh

2. Implementation Notes

2.1. Link calculation

Before a microwave link can be installed, an analysis and calculation of the microwave link must be made first. The analysis should take place before the site survey itself to get a clear idea about the dimensions of the antennas. The analysis consists of the following steps:

• Free space loss calculation

• Link budget calculation

• Rain attenuation

• Multipath fading

• Fade margin

• Fresnel zones calculation

This chapter explains the individual steps and an example of link design is given at the end.

2.1.1. Free space loss calculation

As the electromagnetic waves travel through open space they are attenuated. This attenuation is described as Free-space Loss. This loss depends on the distance travelled by signal and its frequency. Longer distance means greater attenuation and higher frequency means greater attenuation. Freespace loss can be calculated thus:

FSL = 32.44 + 20log f + 20log D

Where:

FSL

free-space loss (dB)

frequency of the emitted signal (MHz)

length of the link (km)

2.1.2. Link budget calculation

To goal is to design a link so that the received signal is stronger than the receiver's sensitivity at the required BER (typically 10-6). Since every radio signal in earth atmosphere is subject to fading, some difference between received signal level under normal circumstances and receiver sensitivity is needed to serve as a fade margin. The minimum value of fade margin can be calculated from the requirement for link availability (e.g. 99.999% of the time). The required margin depends on the length of the link as well as other factors such as rain attenuation, diffraction and multipath propagation.

If we ignore the additional loss along the path, the received signal strenght can be calculated using the formula for signal propagation in free space as follows:

PR= PT+ GT+ GR- FSL

Where

received power level (dBm)

transmitted power (dBm)

RAy Microwave Link – © RACOM s.r.o.10

Implementation Notes

FSL

transmitting antenna gain (dBi)

receiving antenna gain (dBi)

free space loss (dB)

PRmust be:

PR> P

Where:

receiver sensitivity (dBm)

The receiver’s sensitivity defines the minimum level of the received signal at which the receiver is able to process the received signal without losses or affecting the transmitted data (for BER better then 10-6).

2.1.3. Fade margin

Determining sufficient fade margin is the most important step in microwave link design. If the margin is too small, the link will be unstable – as a result, sufficient availability of the link or quality of the provided services cannot be guaranteed. On the other hand, unnecessarily large margin makes the link more expensive (higher performance, larger and more expensive antennas) and increases the cost of creating the microwave link.

The following paragraphs describe the two most significant types of attenuation – rain and multipath attenuation, which are the most frequent along with free space loss. Mutual relation between rain and multipath attenuation rules out the possibility that the link could be affected by both types of attenuation at the same time – these types of attenuation do not add up. To determine the fade margin it is necessary to calculate both rain and multipath attenuation. The larger of the two types of attenuation determines the value of fade margin. In areas with high precipitation, rain attenuation can be expected to be more prominent. By contrast, links located in drier climates and little inclination, will suffer more from multipath attenuation.

2.1.4. Rain attenuation

FSL is not the only attenuation that influences the emitted signal. For frequencies of about 10 GHz rain attenuation starts to become increasingly effective. Precipitation is not identical in all areas which is why ITU released a recommendation Rec. ITU-R PN.837-1 for splitting the world into 15 regions according to precipitation intensity see Fig. 2.1, for more detail Appendix B, Rain Zone Map. In the areas with higher precipitation greater rain attenuation must be expected and a greater signal fade margin must be established, see the calculation of link availability.

The following properties are inherent to rain attenuation:

• It increases exponentially with rain intensity

• It becomes significantly larger as the distance travelled increases (>10 Km)

• Horizontal polarization causes greater rain attenuation than vertical polarization

• Rain outage increases dramatically with frequency and path length

Fig. 2.2 shows that rain attenuation is greater for horizontal polarization. In regions with higher precipitation the difference in attenuation is more marked. The microwave links RAy17 and RAy24 uses both polarizations, hence the need to consider worse of the two, i.e. horizontal polarization. When ACM is

13© RACOM s.r.o. – RAy Microwave Link

Implementation Notes

active we recommend using horizontal polarization on the direction with lower data traffic (typically uplink).

2.1.5. Multipath fading

Multipath fading is another dominant fading mechanism. A reflected wave causes a phenomenon known as multipath, meaning that the radio signal can travel multiple paths to reach the receiver. Typically, multipath occurs when a reflected wave reaches the receiver at the same time in opposite phase as the direct wave that travels in a straight line from the transmitter.

Multipath propagation gives rise to two kinds of signal degrading effects, i.e., flat fading and frequency selective fading. Flat fading is a reduction in input signal level where all frequencies in the channel of interest are equally affected and is dependent on path length, frequency, and path inclination. In addition, it is strongly dependent on the geoclimatic factor K.

To calculate the probability of outage due to multipath propagation of microwave links ITU-R probability model can be used which describes a single frequency (or narrowband) fading distribution suitable for large fade depths A in the average worst month in any part of the world (based on ITU-R P.530-14) and for detailed link design is given as follows [1]:

2.1.6. Fresnel zones calculation

The position of obstacles between points of the bridge can significantly influence the quality of the microwave link. The radio signal doesn't only radiate along the line of sight, but also in the area around it, i.e. in the so-called 1st Fresnel zone. Within this zone 90 % of the energy is transmitted between the transmitter and receiver antenna. This space has the shape of an ellipsoid. If it is disturbed the link has worse transmission properties and a higher quality antenna is required. For this reason the position of the antenna can be just as important as its height above ground. 60 % of the 1st Fresnel zone is considered as the most important.

Fig. 2.6: Fresnel zone

The general equation for calculating the first Fresnel zone radius at any point P in between the endpoints of the link is the following:

Where:

F1first Fresnel Zone radius in metres

d1distance of P from one end in metres

d2The distance of P from the other end in metres

λ wavelength of the transmitted signal in metres

The cross sectional radius of each Fresnel zone is the highest in the center of link, shrinking to a point at the antenna on each end. For practical applications, it is often useful to know the maximum radius of the first Fresnel zone. From the above formula calculation of the first Fresnel zone can be simplified to:

where:

= 2.62 dB/km => for 4km distance 10.5 dB

Step 3 - Attenuation due to multipath propagation

We have to find required fade margin for reliability of the link 99.99 percent. Path inclination:

The percentage of time that fade depth A (dB) is exceeded in the average worst month is calculated as:

For reliability 99.99% is P0=0.01 we get exponential function for A:

A = -0.19765 - 10log(0.01/0.022871) = 3.4 dB

The minimum fade margin required to suppress multipath fading on this link would be 4 dB.

Step 4 - Link budget calculation

Calculation in steps 2 and 3 determines the minimum fade margin required for stable link operation as 11 dB (rain attenuation is dominant). If you use the maximum performance of antenna with diameter of 30 cm, complete the radio formula as follows:

PR= PT+ GT+ GR− FSL = 5 + 32.2 + 32.2 − 129.1 = −59.7 dB

Fade margin:

A = |PS| − |PR| = 79 − 59.7 = 19.3 dB

The resulting fade margin is larger than the required 11 dB. Current legislation in the Czech Republic allows maximum EIRP of +20, i.e. the sum of transmit power and antenna gain at the transmitter can be 20 dB at the most. For 99cm antennas, TX power can be up to 20 - 42 = -22 dB, the resultant equation is as follows:

17© RACOM s.r.o. – RAy Microwave Link

Implementation Notes

PR= PT+ GT+ GR− FSL = -22 + 42 + 42 − 129.1 = −67.1 dB

Fade margin:

A = |PS| − |PR| = 79 − 67.1 = 11.9 dB Fade margin is now only 12 dB which corresponds to link availability > 99.99% of the time in a year. Technical literature often gives the minimum fade margin of 20 dB. For very long links (more than

10 km) fade margin will, indeed, be approximately 20 dB. For shorter links, however, such large margin is not necessary. It is helpful to first conduct the calculation above to receive an idea of the attenuation affecting the link.

The result

To achieve the required transmission capacity and link availability for link distance of 4 km, transmit power -22 dBm and 99 cm antennas were selected for both sides of the link.

Bandwidth is selectable from 1.75 up to 56 MHz. Modulation can be fixed or adaptive and can be adjusted from QPSK to 256QAM.

Fig. 3.1: RAy – Microwave link

The link is formed by two FOD (Full Outdoor) stations. In the case of links operating in the ISM bands (RAy17, RAy24), both stations have identical hardware. In the case of links operating in the licensed bands, one unit is transmitting in the Lower and receiving in the Upper part of the band. The other unit is operating vice versa.

RAy links are used with external parabolic antennas. Parabolic antennas from different producers are available.

Cross polarization - valid only for links operating in the ISM bands (RAy17, RAy24):

One side of the link uses one polarization for transmission (e.g. horizontal) and the opposite polarity for receiving (e.g. vertical). The other side of the link is turned by 90°. It therefore transmits and receives using opposite polarizations with respect to the other side.

3.6. Ordering codes

3.6.1. Microwave units

The proper pair of Lower and Upper units should be selected when ordering the microwave link. This is not true for ISM bands units (RAy17, RAy24). In such a case the same unit is used for both sides of the link.

Note - The Lower and Upper unit has to be selected from the same sub-band (i.e. from the same row of the table).

The RAy10 ordering codes are stated here for clarity. The RAy10 User manual can be found here3.

In case of the two-port units, the “-2” label shall be connected to the end of the ordering code. Example:

• RAy11-LA-2

• RAy17-2

3.6.2. Feature keys

The Feature keys ordering code consists of three parts:

XXX-YYY-ZZZ

• RAy11-SW-100 ... RAy11 user data speed max. 100 Mbps.

• RAy17-SW-360 ... RAy17 user data speed max. 360 Mbps.

XXX - Product type, e.g. “RAy11”. YYY - Feature key type.

The "SW" key is available now. This key unlocks the User speed to given value.

4. Step-by-step Guide

The following chapters will guide you step by step through preparation, installation and activation of the RAy link:

• Pre-installation check out

• Installation

• Advanced configuration

• Troubleshooting

Pre-installation Checklist

Familiarise yourself with the controls and prepare your configuration ahead of the installation of the link on the mast tube.

Both units (without antennas) can lie on a desk with flanges running parallel and facing up at an angle, on a non-metal desk they can also face downward. In the case of units operating in the ISM band (RAy17, RAy24), turn unit holder so that they are roughly perpendicular to each other. In the case of units operating in licensed bands (RAy10, RAy11), turn unit holders so that they are roughly parallel to each other. Use an ethernet cable to connect each of the units to a PoE source and connect a PC to one of them for configuration.

Take the following steps to establish a connection between the PC and RAy and perform a basic setup.

Step-by-step Guide

Fig. 4.1: Link Configuration

Warning

During operation, never bring waveguides of both stations close to each other. There is a risk of damaging sensitive input circuits.

4.1. Service access

RAy link is supplied with a default configuration of access parameters:

Unit L has the service IP address 192.168.169.169 and mask 255.255.255.0, Unit U has the service IP address 192.168.169.170 and mask 255.255.255.0, access is allowed over HTTP, HTTPS or SSH, the username is admin and the password is also admin.

On your PC setup an IP address that is within the mask, i.e. 192.168.169.180.

Then open the https configuration interface, e.g. https://192.168.169.169

Other access options are described in the chapter Settings – Service Access of this manual.

When connectionhas been established, use the Settings – Service access – Services menu to customise access parameters. Default IP addresses should be replaced with well-chosen operating addresses. Leaving default addresses in place can lead to network problems later.

RAy Microwave Link – © RACOM s.r.o.28

Step-by-step Guide

The menu contains parameters for the entire link, both for the Local and remote Peer units. If a connection has been established, both sets of parameters have been set. While working with an isolated unit, only Local parameters are functional for the currently connected unit.

Note

If link is OK and there are no parameters shown of the station Peer, it is necessary to click on Refresh.

Follows the description of basic settings. After entering values on the screen always save the content by clicking on Apply.

4.1.4. Menu Maintenance – Feature keys

Firmware of the microwave link is capable of limiting the maximum user data speed. The Feature key to unlock specific user data speed should be installed prior to unit physical installation. The microwave link can be operated only at the lowest speed (according to link type down to 5 Mbps) without the installed Feature key. For further details see Feature keys.

4.2. Basic link configuration

Default radio parameters depend on the specific type of link and the specific channel allocation table. Channels are typically set in the lower part of the band, the smallest bandwidth, QPSK modulation, and low power. Both units in the pair should be capable of immediate communication. If it is possible to work with these radio parameters at the installation location, the link can be activated. On an operating link, required operating parameters can then be set up.

If a change in the parameters is necessary, it is done in the menu Settings – Radio and saved by clicking Apply. This applies when working on both units simultaneously if they are connected, otherwise each unit is configured individually. When configuring units individually, pay attention to correct settings of duplex pair for channels TX and RX. For example, if one station has TX channel L1, then the second station must also have the channel RX L1.

RAy Microwave Link – © RACOM s.r.o.32

Step-by-step Guide

4.3. Link test

Verify the functionality of the radio link. Switch in screen Status - Brief:

•

Status Bar displays Link: Ok. If the alarm message appears at Local or Peer, this doesn’t necessarily mean there is a problem. The message indicates that the limit at any of the monitored parameters has been exceeded. Essential is the Link: Ok message.

•

The Status screen contains values for both Local and Peer units. N/A next to Peer indicates that the data from the Peer unit has not been transferred. If Link is Ok, simply click Refresh at the bottom of the screen and Peer data will be updated.

•

Menu Status – Detailed – Radio indicates link RSS and SNR values, in case of ACM also the selected modulation and Netbitrate. If the ATPC function is enabled (menu Settings – Radio) it also indicates instantaneous / max. allowed power and for SNR and RSS values it indicates immediate / target value size.

•

Menu Tools – Graphics – Bar indicators display current size of RSS, SNR and BER.

•

Menu Tools – Ping allows you to send a ping test to the selected IP address.

Try out the possibility of modulation:

•

Modulation ACM. In menu Settings – Radio enable ACM. Set the TX modulation parameter to the required maximum value. In menu Status – Brief – Radio you can monitor (Refresh or Start) changes in used modulation based on the instantaneous SNR signal quality. Status and quality of modulation is demonstrated well in menu Tools – Graphics – RX constellation diagram, hit Refresh.

•

To set a fixed modulation go to Settings - Radio, switch off ACM and set the TX modulation to a value from the range of QPSK through 256-QAM based on the results of the previous test. If you choose modulation higher than allowed by SNR, the connection will be lost. Status Link will lose its Ok value. Both units will need to be moved closer to resume the link. If this is not possible, use ethernet to access each unit individually and set the basic modulation QPSK. You can monitor the quality of the received signal under Tools – Graphics – RX constellation diagram.

Verify the functionality of the entire link:

• If possible, connect user devices to both RAy units over PoE and test mutual communication.

• Another way of testing this is to connect a PC to the other unit and send a ping from one PC to the other.

• The minimum variant of this test is to use ethernet cable connection from the PC connected to the local RAy to the PC connected to the remote RAy and test communication between both units over ethernet. This will verify ethernet functionality.

Prepare installation configuration:

• Bandwidth e.g. 3.5 MHz. To get the highest possible receiver sensitivity, set the bandwidth as narrow as possible according to specific frequency band.

• TX channel: Use your allocated channel. If you don't have allocated channel yet, use for example channel L1.

• RX channel will setup automatically when channel lock activates.

• TX modulation QPSK to get the highest possible sensitivity.

• RF power according to selected antenna and according to individual frequency licence. Set the output power as high as possible.

• Record the access parameters from the Service access menu, especially the IP addresses.

33© RACOM s.r.o. – RAy Microwave Link

Step-by-step Guide

• Restart by interrupting power supply to verify that the parameters are stored correctly and the link works.

After this preparation phase you can continue to install your devices in working environment.

Installation

5. Installation

5.1. Line of sight test

Before you install the device to a mast tube, verify visually that the view in direction of the remote unit is unobstructed. Watch out for these obstacles in particular:

• Free Fresnel zones. Signal needs space wider than the diameter of the antenna.

• Trees at the lower end of the Fresnel zone. They will be taller in a few years.

• Possible building development.

• Objects in the close proximity of the antenna such as edges of other antennas, their mounting racks, edges of the roof.

5.2. Antenna mounting

5.2.1. Mounting methods

• according to the method of mounting on the mast tube ○ right-side mounting ○ left-side mounting

• according to the method of mounting the FOD unit – antenna polarization ○ horizontal mounting ○ vertical mounting

In both cases mount the unit with the connectors facing downwards at an angle.

Installation

Fig. 5.3: Right-side mounting – horizontal RX polarization

Changing the mounting method

Antenna bracket is supplied as standard partly assembled, and ready for right-side mounting.

On changing the Jirous antenna bracket for left-side mounting the adjustment bolt (part No. 11) and swivel bolt (part No. 12) need to be unscrewed, then shift the bracket body (part No.13) to the other side of clamp plate (part No. 4), (do not turn upside down) and then insert bolt (part No. 12) into the second hole on the mounting plate holder and through the same hole on the clamp plate and secure in place with the nuts. The adjustment bolt (item No. 11) and nuts (item No. 9) are switched to the other side of the clamp plate (part No. 4). It is also necessary to switch the hanging bolt (part No. 7) on the mounting plate (part No. 5) to the second hole so that after switching sides with the antenna it is on the top again.

On changing the Arkivator type antenna bracket for left-side mounting the adjustment pin (part No.

17) needs to be unscrewed and switched to the other side of the bracket body (part No.3) and clamp plate (part No. 4). It is also necessary to switch the adjustment bolt (part No. 21) and U-plate (part No.

13) to the other side of the bracket body (part No.3). This ensures that there is still good access to the adjustment elements for changing the direction of the antenna when mounted on this opposite side.

In the case of the antenna when changing the method of mounting from right-side to left-side it is only necessary to change the eye hook on the top and rotate the plastic cover of the antenna. This is not only important from an aesthetic point of view, so that the RACOM logo is not upside down, but also because there is a discharge channel on the lower edge of the dish (except for ø380 mm dishes).

When changing the polarization from horizontal to vertical only the FOD unit needs to be turned through 90° around the central antenna pin by unscrewing the four bolts on the dish using a No. 6 Allen key. (or on the reducing crossplate (part No. 7) for the Arkivator type antenna)

Important

The RAy17 and RAy24 links are equipped with a polarization duplexer and work in both polarizations simultaneously, see Cross polarization. One side of the link must therefore be installed in vertical polarization and the other in the horizontal polarization.

Installation

5.2.2. Mounting the FOD unit on the antenna

RAy microwave bridge equipment is generally supplied as several component parts packaged separately in a box.

• Two parabolic antennas.

• Two brackets for mounting the antenna to the mast.

• Two FOD stations, each separate in a box, in a single package.

• Other accessories based on the order placed (for more detailed information see chapter Section 3.7, “Accessories”)

When ordering a RAy microwave bridge there is a choice of antennas from two manufacturers to be connected to the RACOM FOD unit.

Mounting the FOD unit on the Jirous antenna

A No. 17 spanner and a No. 6 Allen key are required for mounting the mechanical parts of the antenna. Spanner No. 17 serves for precisely setting the direction of the antenna. Both spanner and key can be found in the RAy Tool set for installing RAy microwave bridges.

Fig. 5.4: Close up image of the mounted bracket showing numbered parts

37© RACOM s.r.o. – RAy Microwave Link

Installation

a. Prepare the antenna bracket based on the diameter of the mast tube. For smaller diameters face

the bent part of the saddle plate (part No. 3) inwards. For larger diameters it should face outwards. Screw the bolts (part No. 1) into the clamp plate (part No. 4) so that they protrude approx. 1 cm through the clamp plate. Clamp the saddle plate to the mast by tightening the nuts (part No. 2) on the bolts.

Fig. 5.5: Position of the saddle plate for ø 40–80 mm

b. Slide the antenna bracket onto the mast tube and clamp to the mast by tightening the nuts.

Fig. 5.6: Position of the saddle plate for ø 65–115 mm

Fig. 5.7: Attaching the bracket to the mast tube

RAy Microwave Link – © RACOM s.r.o.38

Installation

c. The second part of the bracket – mounting plate (part No. 5), is screwed to the antenna dish with

three bolts (part No. 6). Screw the eye hook into the upper threaded hole of the dish to ease handling of the dish during installation. The position of the eye hook on the dish and hanging bolts on the plate change according to the type of installation, see Section 5.2.1, “Mounting methods”.

Fig. 5.8: Dish without mounting plate Fig. 5.9: Dish with mounting plate

d. Screw the hanging bolt (part No. 7) into the upper hole of the mounting plate so that the antenna

can be hung on the mounting plate holder. Hang the antenna on it and tighten the lower bolt. (part No. 8)

Fig. 5.10: Hanging the bolt on the holder Fig. 5.11: Correct position of the mounting plate

39© RACOM s.r.o. – RAy Microwave Link

Installation

e. Tighten both bolts to the plate before continuing with installation to prevent any unnecessary

movements of the whole equipment. Before precisely adjusting the vertical direction of the antenna upon completing installation it will be necessary to unscrew them again as the lower bolt passes through the adjustment block and the upper one serves as the axis of rotation.

Fig. 5.12: Tightening the upper bolt to the mounting plate

f. Before installing the FOD unit on the antenna first unscrew the 4 bolts on the back of the antenna

enough so that the unit can be slid on to them. Then check whether the "O" ring is correctly fitted on the antenna pin, and make sure it is not damaged and has been lubricated with grease – see Section 5.2.3, “Lubrication and preservation of the antenna pivot”. Then remove the protective plastic cover from the central pin of the antenna and fit the FOD unit to it carefully so as not to damage the "O" ring. Secure it in place with the four bolts. Carefully ensure the correct polarization of the antenna – see Section 5.2.1, “Mounting methods”. Finally tighten the bolts with a No. 6 Allen key.

Installation

g. The precise horizontal direction the antenna is pointing in can be adjusted using the bolt with two

nuts (part No. 9). Once the direction has been set the antenna is fixed in place by tightening the nuts against the bracket to prevent further movement of the antenna. The vertical direction the antenna is pointing in can be adjusted by turning the fine adjustment bolt (part No. 10) by the bracket mounting plate. After selecting the correct direction the position is secured by tightening the bolt – see point e (part No. 7 and 8). The correct position in both directions is found by monitoring RSS – voltmeter, or with an audible alarm (if equipped) – see Section 5.5.2, “Antennas directing”.

Fig. 5.16: Horizontal adjustment of the antenna direction

h. After pointing the antenna in the right direction tighten the bolts on the bracket on the axes of rotation

(part No. 11 and 12). Then check again that all other bolts have been sufficiently tightened. We can now proceed to connecting the FOD unit to the user network.

Mounting the FOD unit on the Arkivator antenna

Installation of a RAy microwave bridge with an Arkivator type antenna is very similar to the installation described above, and is clear fromthe following images. The tools required for installation can be found in the RAy Tool kit for installation of RAy microwave bridges. No. 13, 16 and 17 spanners and No. 4 and 6 Allen keys are required for installation. For an antenna with a nominal diameter of 120 cm a No. 14/24 double open ended spanner, supplied with the antenna.

From 2013 Arkivator antenna is delivered with a slightly different bracket, see Fig. 5.24, “Arkivator antenna bracket, version 2013”. Assembly process is similar.

Installation

Fig. 5.21: Installation diagram for the Arkivator antenna, 99 cm, version 2012

The antenna bracket (part No. 3 and 4) is supplied assembled as per the following image. The bracket is installed on the mast tube in a similar way to that of the Jirous antenna (point a). The bracket is ready for tube diameters up to 115 mm. The bolts (part No. 6) should be screwed to the clamp plate (part No. 4) in such a way that the end of the bolt protrudes approx. 6-10 mm through the other side of the clamp plate. Saddle plates (part No. 5) are then clamped against the mast tube by tightening nuts (part No. 7).

Warning

Before mounting the adapter (part No. 25) to be removed the green foil from the antenna (part No. 1). This film covers the transport of the center hole in the waveguide.

After mounting the bracket on the mast tube, bolt the bent plate (part No. 2, for Arkivator 30 and 60) or (part No. 30, for Arkivator 99) to the bracket. The actual antenna (part No. 1) is then bolted to this plate.

Installation

Fig. 5.22: Arkivator antenna bracket (2012)

A reducing adapter (part No. 25), a reducing crossplate (part No. 21) and sleeves (part No. 22) are used for mounting the FOD unit (part No. 20) on the antenna. During installation do not forget "O" rings (part No. 26 and 27) and to lubricate the "O" ring (part No. 27), see Section 5.2.3, “Lubrication and preservation of the antenna pivot”.

Bolt (part No. 14) serves for accurately setting the vertical direction of the antenna. When setting the direction release bolt (part No. 12 and 13), and then tighten it again once you have the correct position. The nuts on bolt (part No. 10) serves for setting the horizontal direction. Once the direction is set these nuts (part No. 11), pivot bolt (part No. 9) in the hanging eye of bolt and two pivot bolts (part No. 8) where the tilt bracket is need to be tightened.

5.2.3. Lubrication and preservation of the antenna pivot

Before fitting the FOD unit bush onto the antenna pivot ensure that the "O" ring (part No. 1) is in the correct position. It is also essential to prevent moisture getting in between these two parts. This moisture could cause oxidation which would complicate disassembly of this mechanical coupling in the future. For this reason we need to treat these surfaces with the lubricant grease which is supplied in the box marked RAy bridge accessories. If you use a different grease for lubrication then it should be a Teflon grease or a silicon lubricant grease.

Fig. 5.28: Grease points on the antenna pivot and FOD unit bush

Grease the internal area of the bush on the FOD unit (2) and the "O" ring (1) with a thin even layer that allows the pin to slide easily into the bush without damaging the "O" ring. Grease the area beyond the "O" ring on the antenna pin (3) with a thicker layer so that it fills the gap caused by the play between the pin and the bush (max. 0.1 mm/ø) thus preventing moisture getting in. Installation should be carried out according to the antenna installation description – see point f of this description.

5.3. Connectors

5.3.1. Connecting the FOD communication unit to the user network

The FOD communication unit is connected to the user network by an Ethernet cable via interfaces GbE, IEEE802.3ac 1000BASE-T. As standard, RACOM recommends using an S/FTP CAT 7 cable and two RJ45 connectors for outdoor installations. One for the internal (IE-PS-RJ45-FH-BK) and the second for the external (plastic IE-PS-V01P-RJ45-FH or metallic IE-PS-V01M-RJ45-FH) end of the cable.

Based on the PoE standard the station is powered over the Ethernet cable.

If the station is equipped with two connectors, the right one carries user data, and the left connector is to be used for servicing.

The middle BNC type connector serves for connecting a voltmeter for precisely setting direction.

Fig. 5.29: Connecting the FOD communication unit

Important

Before connecting the FOD communication unit to the supply (to the user network) the FOD unit must be grounded according to Section 5.4, “Grounding”.

It is necessary to install the antenna lead so that there is no excessive mechanical stress applied on the Ethernet connector.

Fig. 5.30: Example of a correct lead installation.

Installation

5.3.2. Fitting an external IE-PS-V01P-RJ45-FH connector

We recommend using an S/FTP 4×(2×23AWG) Cat.7 + 2×(2×24 AWG) cable for connecting the FOD unit, as it is designed for external use. The cable contains two additional twisted pairs, 2x(2x24 AWG), which are not used. The following images show the internal cable without these additional pairs.

a. Use the tools from the RAy Tool set for fitting connectors. See Section 3.7, “Accessories”.

Fig. 5.31: Tools for fitting connectors Fig. 5.32: IE-PI-RJ45-FH connector before

fitting

b. Undo the nut on the connector cover and push it on to the cable. Then trim at least 20 mm of insu-

lation from the end of the cable.

Fig. 5.33: Tool for removing insulation Fig. 5.34: Insulation removed

c. Twist the braid forming the cable shielding together and wrap around the cable so that 2-3 loops

are next to each other at the end of the insulation.

d. Separate individual pairs of conductors, remove the aluminium shielding from them, cut it off, and

separate individual conductors. Cut off the two additional twisted pairs from the thinner wire in the middle (not seen on these images).

Fig. 5.37: Trimming shielding Fig. 5.38: Separated pairs of conductors

e. Push the lower layer of conductors into the openings as per the pinout sticker (T568B) attached

to the connector. Take care not to confuse white conductors from individual pairs.

Fig. 5.39: Pushing the lower pairs into the connector

the connector according to the pinout sticker and trim them. The cable must be pushed in far enough so that the braided shielding is inside the metal part of the connector.

g. Remove the pinout sticker and fit the complementary half of the connector. Squeeze the parts to-

gether until the locks snap into place. Use the pair of pliers with parallel jaws from the RAy Tool set for this. Standard pliers would damage the connector.

Fig. 5.43: Fitting the complementary half of the connector

h. Then slide the protective cover onto the connector. It must fit into the grooves after snapping into

place. Finally tighten the nut on the cover to seal the point where the cable enters the connector.

e. First insert the lower row of conductors from the back. Then unwind the others and insert them

into the holes for the upper row of conductors, as per the pinout sticker. Ensure that the wrapped around shielding braid is inserted sufficiently to create a good contact with the second part of the connector fitted with sprung contacts. Snap the plastic clamp onto the cable. Squeeze it together tight enough so that it doesn't allow movement of the cable.

5.4. Grounding

The lightning and overvoltage protection system example, designed in accordance with regulation CSN EN 62305.

1. Where possible the antenna should be located in an LPZ 0B protection zone with the use of a

local or artificial air termination device for protection against direct lightning strikes.

2. When meeting conditions for ensuring electrical insulation (distance from the lightning conductor)

in accordance with article 6.3, it is not recommended to ground the load-bearing structure and antenna to the external air termination network. Ground should be connected to the protective system of the internal LV wiring or grounded internal structures using a CYA 6 mm2bonding conductor , see Fig. 5.61, “Grounding installation 1”

3. If it is not possible to set up conditions of electrical insulation in accordance with article 6.3 we re-

commend connecting the load-bearing structure at roof level to the external air termination network via an 8mm diameter FeZn conductor and shielding the data cable before entry to the building with a grounding kit and CYA 6 mm2conductor to the bonding bus, and if not already set up then also to the external air termination network, see Fig. 5.62, “Grounding installation 2”

4. If there is not an external LPS on the building we recommend routing lightning current through an

8mm FeZn conductor to a common grounding system, or to a separate grounding electrode with a ground resistance up to 10 Ω.

5. For limiting the overvoltage transferred over the data cable and into the building we recommend

fitting surge protection at the interface between zones LPZ 0 and LPZ 1 connected via a CYA 4 mm2conductor to the same grounding point as the antenna or the antenna mast.

6. We recommend protecting the PoE power supply from overvoltage on the LV side with suitable

class D surge protection.

conductor. The conductor should have a green/yellow sheath across its whole length. For grounding a RAy grounding kit can be ordered as an accessory (see Section 3.7, “Accessories”) containing a grounding terminal ZSA16, 40 cm grounding strip 15 mm wide, and 100 cm of cable with grounding lugs. For instructions on installing terminals see the datasheet RAy grounding kit1. A qualified person must install the antenna.

Racom supplies surge protection for installationon Ethernet cables entering buildings. For more details see Surge protection2.

Additional safety recommendations

• Only qualified personnel with authorisation to work at heights are entitled to install antennas on masts, roofs and walls of buildings.

• Do not install the antenna in the vicinity of electrical wiring. The antenna and bracket should not come into contact with electrical wiring at any time.

• The antenna and cables are electrical conductors. During installation electrostatic charges may build up which may lead to injury. During installation or repair work to parts of the antenna lead open metal parts must be temporarily grounded.

• The antenna and antenna cable must be grounded at all times. See Section 5.4, “Grounding”.

• Do not mount the antenna in windy or rainy conditions or during a storm, or if the area is covered with snow or ice.

• Do not touch the antenna, antenna brackets or conductors during a storm.

5.5. Start up

Connect a power supply to the installed FOD unit and connect the configuration PC. Use an internet browser (such as Mozilla Firefox) to enter the configuration menu.

5.5.1. Noise on the site

This chapter is particularly true for installation of links working in free bands, where the user has no secured frequency.

Analyse the level of noise in the individual channels using the spectrum analyzer under Tools – Graphics – Frequency analyzer. If necessary adjust the choice of working channel on the basis of the results.

While doing so respect the rule that in one location all units emit signal in the Upper part of the range and receive it in the Lower part of the range, or the other way round. A transmitter must not be installed in the part of the spectrum where other units function as receivers.

5.5.2. Antennas directing

If it is possible, use narrow channel, low modulation and high power for the first antenna directing. Working on both ends of thelink simultaneously is favourable. Connect voltmeter to the BNC connector and observe RSS changes in 2 V DC range. Stronger signal corresponds to lower voltage. Alternate units on both sides and slowly adjust the antenna vertically and horizontally to find the position with

57© RACOM s.r.o. – RAy Microwave Link

Installation

the strongest reception. At the same time look for the main signal maximums. To differentiate between the main and the side maximums refer to Main and side lobes paragraph.

RSS measurement

For correctly setting the bridge and positioning it in the right direction it is advisable to connect a PC and use the diagnostic capabilities of the RAy station. In uncomplicated cases it is enough to connect a voltmeter via a BNC connector and adjust to the lowest indicated voltage. Voltage is calibrated according to signal strength. E.g.: RSS -65 dBm corresponds to voltage 0.65 V, RSS -80 dBm corresponds to voltage 0.80 V etc.

Fig. 5.71: Radiation diagrams

Both antennas should be oriented towards each other using the peaks of radiation diagram. Adjust the antenna alternately in the horizontal and vertical axes and monitor the resulting signal strength. Use the calculation of the expected RSS with the precision of several dBm as guidance. Side lobes transmit signal ca 20 dBm weaker, see the Microwave link Calculation3.

http://www.racom.eu/eng/products/microwave-link.html#calculation

Installation

The resulting RSS helps distinguish between the states A-A and C-C which appear similar. It also helps in situations where simple search for a maximum doesn’t work as shown in the illustration “incorrect adjustment”.

Real radiation diagrams are more complex, especially in that they run differently in horizontal and vertical axes. The basic steps for determining the main radiation lobe however stay valid. For example:

5.5.3. Link test

Basic parameters of the link are shown in the menu Status – Brief, its quality is characterized by RSS and SNR. Values on Status screens can be refreshed manually by pressing the Refresh button or in real time with a period of several seconds after activating the Start button. Press the Stop button to terminate the periodic refresh of values.

The RSS, SNR and BER values can also be viewed on the screen Tools – Graphics – Bar indicators. After pressing the Start button, values will be refreshed with a period of one second.

After installation, it is good to reset the statistics using the Clear stats button in menu Status – Detailed. This allows easier diagnostics of the link’s reliability over time.

5.5.4. Parameters setup

After both antennas have been directed, setup operation parameters for the link. In case of links operating in the free band, setup the parameters based on survey results from the tool Tools – Graphics – Frequency analyser. In case of links operating in licensed band,setup the parameters based on assigned license:

• Bandwidth

• Channel Selection (TX / RX channel)

• Modulation (TXmodulation) – ACM is recommended. When selecting fixed modulation it is necessary to account for the fade margin. If fixed modulation is setup close to a possible maximum, then a deterioration in RSS could endanger the link both for data transfer as well as service access.

• Transmit power (RF power), or ATPC

• Verify and record IP addresses

• Define access channels – https / telnet / ssh / ssh with password

Restart both units by interrupting their power supply and verify the status of the link. This verifies that all parameters have been stored correctly in the memory.

Select Tools – Maintenance – Backup – Settings – Backup - Download and save the configuration to backup file “cnf_backup.tgz”.

This completes the installation. Further configuration can be performed remotely.

TX and RX channels are selected from a list of channels. The basic configuration has the TX and RX options interconnected. In this case the basic duplex spacing between channels is preserved and by selecting one channel, the other three are defined as well. For stations operating in free bands, it is possible to disconnect the TX-RX lock and select TX and RX channels individually. Corresponding channels at peer station are set automatically. Notice – Non-standard duplex setting leads to non-effective use of the spectrum.

Information about duplex spacing of TX and RX channel.Duplex spacing [MHz] Enable automatic control of modulation.ACM Modulation level for TX channel. You can select in range from QPSK (high

sensitivity for difficult conditions) to 256QAM (high speed under appropriate conditions). In case of enabled ACM it has the meaning of the maximum (highest) allowed modulation.

Enable automatic control of RF power. Power is regulated towards lower values while maintaining highest modulation level. Maximum output power is limitted by Tx power parameter. The power control loop is primarily controlled by RSS. The SNR value is taken into account as well, because the situation of high interference value can lead to high RSS but low SNR.

Internal VLAN id

Storm control

Switching between transfer speed and flow control automatic negotiation or manual setting.

Media DependentInterface Crossover enables working with both types of ethernet cables, straight-through and crossover. The default option "auto“ switches on automatic detection and performs an internal crossover if necessary.

Mechanism for temporarily stopping the transmission of data on an ethernet network. Enabling flow control allows use of buffers of connected active network elements for levelling uneven flow of user data. If flow control is enabled, you cannot use the built-in QoS functions. For correct operation it is necessary to also enable Flow control on the connected device.

Setup of maximum allowed length of Ethernet frame. If transfer of tagged frames is not needed, you can choose smaller MTU. If you select smaller MTU, more storage space is available for QoS.

The RAy unit uses one VLAN id for internal needs. It can be changed if there is a conflict with user data.

6.3.4. Settings – QoS

The Quality of Service (QoS) menu groups together multiple options of manipulating user data flow.

Ingress policing

Fig. 6.9: Configuration menu Settings – QoS

Ingress policing – causes user data flow to be limitted to certain value. The excessive packets are discarded.

Ingress policing Enable Ingress policing. Applies to the device user port.

Speed [Mbps] Data rate to limit the Ethernet traffic to. If this speed is exceeded, Flow control

is initiated. If packets are still incoming, they are dropped.

Mode Ingress policer operation mode:

• soft – Flow control is activated at low fill of input buffer. Good to use if the connected device has Flow control enabled and has a large buffer.

• default – Universal settings. Close to “hard” settings, but with Flow control enabled at connected device, packet loss is not possible.

• hard – Flow control is activated only after the input buffer is completely full. Good to use if the connected device has a small buffer.

Warning

The Ingress policing activation deactivates the switch QoS functions.

Queue management

Fig. 6.13: Configuration menu Settings – QoS – Queue management

Setting the operation mode of output queues. These are internal switch queues for organization of packets based on individual QoS rules.

Note

To enable configuring output queues, you must enable at least one of the QoS rules.

Mode Regime for sending out packets from individual queues.

• Strict – If there are packets in a high priority queue, packets from that queue are sent out. Only after this queue is completely empty, packets from a lower priority queue are sent out.

• WFQ – Weighted Fair Queuing. Packets from individual queues are sent out accord- ing to set ratios (see below).

Ratio Mode Turns on the WFQ regime sending out ratio.

Queue 0..3 Setting parameters (ratios) of packets sending out for individual queues.

• Strict column – Maximum output speed [Mbps] for individual queues. Allowed range 0 .. 400 [Mbps]

• WFQ Column – Packet sending out ratios for individual queues. Higher values means more frequent sending out from the given queue.

Configuration

Smart discard

Setting mode for packet dropping in case of insufficient output channel capacity. Packets are dropped with certain probability before the queue is filled completely. For example, this mechanism prevents blocking of high priority packets by low priority packets. The “early random discard” mechanism is proving to be useful particularly for TCP traffic.

Smart discard mode can be used independently of QoS. To ensure correct function of Smart discard (i.e. Mode 1..3) Flow control is off.

Queue 0..3 Setting drop mode for individual output queues

• Mode 0 (0/0) – Packets are dropped only after output queue is fully congested. Smart discard mode is therefore turned off.

• Mode 1 (0/25) – When the queue is full to 3/4, packets will be dropped with 25% probability.

• Mode 2 (25/50) – When the queue is full to 2/3, packets will be dropped with 25% probability. When the queue is full to 3/4, packets will be dropped with 50% probability.

• Mode 3 (50/75) – When the queue is full to 2/3, packets will be dropped with 50% probability. When the queue is full to 3/4, packets will be dropped with 75% probability.

■ Feature keys

Fig. 6.27: Configuration menu Tools – Maintenance – Firmware

The sub-set of RAy parameters is affected by use of Feature keys. The feature keys limiting data transfer speed [Mbps] are now available. Speed of the transferred data is determined by a combination of the radio channel bandwidth (parameter Bandwidth [MHz]) and modulation order (parameter TX modulation). The Feature key limiting the data transfer speed enables only certain combinations of the channel bandwidth and modulation order to get the data transfer speed according to the Feature key. The data transfer speed is typically slightly higher than declared. When installed, the Feature key is activated after the station restart. The station can be restarted using the Tools-Maintenance-Restart menu. Choose the warm Restart mode.

Using the telnet client to connect to unit with service IP address 192.168.169.169. Type this in the command prompt:

telnet 192.168.169.169

Then use the username and password from the menu Service access/Users for https access (by default admin, admin). Works if Service access/Services/Telnet is checked in https access.

Connection using putty client. Type this into the Host Name (or IP address) field:

admin@192.168.169.169

Click Open. Then enter the password admin. This procedure (without key) is subject to selection Service access/Services/SSH on in https access.

If you own the private key part, then you do not need a password. In putty, continue by selecting Connection/SSH/Auth and selecting path to file with key e.g. key.ppk. Use Session/Logging to save the putty configuration. To access the unit via CLI simply select the connection in putty and click Open.

Connection using client ssh in Linux.

ssh admin@192.168.169.169 -i key

If you know the password and it is enabled in Service access/Services/SSH onlykey in https access, you can skip the key and use password in the next query.
