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:

P0= Kd

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.

ZZZ - Feature key value. In case of User speed it states Mbps. Example:

The microwave bridge comes supplied as standard with:

• two FOD units

• two antenna dishes with brackets for mounting on a mast – based on the user requirements and specifications

• tub of NOVATO silicon lubricant (mixture of silicon grease, PTFE and other additives) for lubricating the antenna pin. (see Section 5.2.3, “Lubrication and preservation of the antenna pivot”)

Microwave bridge accessories need to be ordered separately, for further details please see www.racom.eu

• Two pieces of parabolic antennas with mast holder - according to user needs and specifications. The antenna from two different vendors are available currently (year 2013). The overview of different antenna types is listed in paragraph Dimensions. The antenna choice determines radio link properties. The radio link calculation should be performed to determine proper antenna size. Rough calculation can be done using simple on-line calculator.5. The other antenna producers can be used with RAy links as well. The RAy unit can be attached to the antenna by flexible waveguide or directly by means of special interconnetion part. There are several types of those parts for Andrew and Arkivator antennas. It is possible to develop the interconnetion part also for other antenna types.

• FOD unit power supplies – 30W PoE adapters

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.

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.

Note

If there is any problem with https certificate after completing the firmware upgrade, please see the Annex Appendix E, Https certificate for further steps.
