2.3 Installation Overview
Standard installation involves the following steps:
1. Verify that all components of the pack ing list, described in Section 2.1, are intact and verify
availability of the required items liste d in Section 2.2.
2. Ins ta ll the unit and antenna in optimal locations as de s c ribed in Sections 2. 4 a nd 2.5 and in
the instructions su pplie d with the antenna.
Note:
To avoi d drilling unnec essary holes, it is recommended to verify good connectivity wit h t he
base station prior to drilling holes in the locations intended for the SU-R unit and/or the
detached antenna.
3. Connect the antenna to the unit as desc ribe d in Section 2.6.
4. Connect the power supply and the user’s equipment to the unit as desc ribed in Section 2.7.
5. Configure the basic sys te m parameters as described in Section 3.
6. Align the antenna for optimal connectivity (A7 models) and configu re the Maximum Data
Rate if applicable, as described in Chapters 4 and 5.
7. Check the functionality of the unit as describe d in Chapter 6.
2.4 Installation Guidelines
This sec tion desc ribe s the installation guidelines and the various co nsiderations that must be
taken into account when planning the installa tion.
2.4. 1 Location of the Uni t
• The unit can be placed on a desktop or a shelf, or can be attached to a wall.
• The unit should be installed as neat as possible to the antenna (-A7 models). The RF cable
connecting the unit to the antenna should be as short as possible to guarantee minimum power
loss.
SU-R Installation Manual 3 BreezeACCESS II Series
Basic Installation
• Keep the units well away from sources of heat, such as radia tors , air-conditioners, etc.
2.4. 2 Location of the Antenna
• Any physical object in the path between two units can cause s ignal attenuation. Commo n
obstructions are buildings and trees. If a unit’s antenna is installed indoors , the walls and/or
windows between the two sites are physica l obs truc tions. If the antenna is positioned
outdoors, any buildings or other physical s tructure such as trees, mountains or other natural
geographic features higher than the antenna and situated in the path between the two sites can
constitute obs tructions.
• Insta ll indoor antenna s as c lose as pos s ible to a window (or wall if a window is not
accessible) facing the required direction. The UNI-7 or UNI-8.5 antenna may also be attached
to a fixed wind ow. Avoid metal obs tac le s s uc h as metal window frames or metal film antiglare windows in the trans mission path. Install outdoor antennas high enough to avoid any
obstacles , which ma y block the signal.
• Position the antennas c le ar of metal furniture and away from moving metal objects s uc h as
metal fans or doors.
2.4.3 Antenna Diversity
In a pplic atio ns where no multipath propagation is expected, a s ingle antenna is sufficient to ensure
good performance levels . However, in cas es where multipath propagation exists, BreezeCOM
recommends that two antennas be used. This takes advantage of space diversity capabilities. By
using two antennas per unit, the system can select the best antenna on a per-packet basis (every
seve ral milliseco nds).
Multipath propagation is to be e xpected when there are pote ntial reflectors be tween the Access
Unit and Subscriber Units. These reflectors may be buildings or moving objects such as airplanes
and motor vehicles. If this is the case, the radio signal does not travel in a straight line , but is
reflected or de flec ted off of the object, creating multiple propagation paths.
When installing a s ingle antenna , modify the transmit diversity option to either antenna 1 or
antenna 2, according to the antenna being used.
2.4.4 Antenna Polarization
Antenna pola rization must be the same at either end of the link. In mos t a pplic a tions, the preferred
orientation is ve rtical polarization. Above-ground propagation of the signal is better when it is
polarized vertically. For integral omni a ntennas (A model), make sure that the antennas are
BreezeACCESS II Series 4 SU-R Installation Manual
Basic Installation
extended upward vertically in relation to the floor to achieve vertic al p olarization. For the
detached UNI-7 or UNI-8.5 antenna (A7 model) follow the instructions included with the a ntenna.
2.5 Wall Mounting the Unit
Note:
The template on the pac ka ging box can be used to mark the locations of the screws on the wall
(drill right through the markings on the box).
After insertion of the a nchors and screws, hang-on the unit on the two screws with the bottom
panel (the side with the connectors) facing downward.
In SU-R-A models with integral antennas, extend the a ntennas upward vertic ally in relation to the
floor to achieve vertica l pola rization.
To avoi d drilling unnecessary holes, it is recommended to ver ify connectivity with the base
station prior to drilling holes in the locations intended for the SU-R unit and/or the indoor
antenna.
2.6 Connecting the Antenna (A7 m odel)
Connect the special adapter to antenna port 1 (marked 1) on the side of the unit. Push the adapter
carefully into the hole us ing the alignment markings on the adapter and the unit, and turn it 180
degrees to firmly lock it.
2.7 Connecting the Uni t to the Power Supply and to the CPE
The unit operates on a power input of 5V DC, supplied by the power transformer include d with
the unit.
1. Plug the output jack of the power transformer into the DC input jack (ma rked DC IN)
located o n the bottom panel of the unit.
2. Connect the supplied universal power transformer to a powe r outlet - 110/ 220VAC.
3. Use a straight Ethernet 10BaseT cable to connect the Ethernet port (marked ETH) to a PC or
to a hub’s uplink port. Use a crossed cable to connect to a hub.

order to optimize the quality of the link with the Access Unit.
For a Subscriber Unit with a directional antenna, you can eithe r use the LED indicators on the
front panel of the unit or view the Received Signal Strength Indication (RSSI) using the monitor
program. In most installations, alignment using the LEDs is s ufficient. T he RSSI reading can be
used when finer alignme nt is required (see 3.2).
Note:
Antenna ali gnment of the Subscribe r Unit is possibl e only afte r the Ac c ess Unit you wish to
ass ociate wit h i s operational and the bas ic par ameter s were properly configured as
des cribed in Section 3.2.
4.1 Aligning the Antenna Using the LEDs
1. The H (high), M (medium) and L (low) LEDs on the front panrel of the unit indicate the
quality of the link. The higher the number of illuminated LEDs the better is the quality of the
link.
2. Rotate the antenna left and/or right until you reach the point of maximal signal quality
reading on the H, M and L LEDs. Make sure that at all times, the front of the antenna faces
the general direction of the Access Unit. In some cases, e.g. when the unit is very close to
the base station you may need to tilt the antenna upward or downward.
3. For proper operation, at least one (L) LED should be illuminated. If this is not poss ib le,
improve the link quality by plac ing the antenna at a higher point or in a different location.
4. After the antenna is optimally aligned, sec ure the antenna to guarantee that it will rema in in
the selecte d pos itio n.

From Wlan Only.
ESS ID
•
– The ESSID (Extende d Service Set ID) of the unit (up to 32 printable ASCII
characters). The ESSID is a string used to identify a wireless network. It prevents the
unintentional merging of two co-located wireless networks. A n SU can only as s o cia te with an
AU that has an identical ESSID. Use different ESSIDs to segment the wireless access network
and add security to your network. The default value is

units operate at 1 Mbps , 2 Mbps or 3 Mbps . Under certain conditions
(compatibility rea sons or range/spee d tra d e -off), you may decide to limit the use of higher
rates. If the quality of the link is not good enough, it is recommended to decrease the value of
these pa rameters (t he higher the date ra t e , the higher the error rat e ). Otherwise, there is a high
probability that the unit will have to re transmit many frames several times be fore te mporarily
reducing the data rate. A high number of retransmissions reduces the overall throughput for
the selected SU as well as for all the other SUs served by the same AU.
The link quality can be estimated based on the RSSI measurement using the Continuous Link
Quality Dis pla y in the SU. If the me a s ured RSSI is less than a certain threshold, it is
recommended to decreas e the Maximum Data Rate of the SU in accordance with the following
table:
Recommended Maximum Data Rate 3Mbps 2Mbps 1Mbps
BreezeACCESS MMDS SU-I/ID RSSI>65 53<RSSI<65 RSSI<53
The default value is 3 Mbps. Allowed values are 1, 2 or 3 Mbps.
The AU learns the Maximum Data Rate used by each SU during the association process, and
uses this rate for transmissions to the spec ific SU.
Transmit Antenna
•
– Displays which antennas are used for transmission. SU-R units s upport
transmit antenna diversity (2 antennas). During reception, a BreezeACCESS unit that is
connected to two antennas dynamically selects the antenna where reception is optimal. In
contrast, if the transmit antenna diversity is e nabled, the unit selects the antenna from which it
will transmit before the actual transmission. It usually use s the antenna last u s ed for
succes s ful transmission. In installations whe re a model that can support antenna diversity is
connected to a single antenna, T ransmit Antenna Divers ity should be configured to transmit
only from that single antenna. Available selections are:
⇒ Us e Two A nt ennas
⇒ Use Antenna No. 1
⇒ Use Antenna No. 2
