Basic InstallationBreezeACCESS 2.4 Series 7 SU-A/E Subscriber Units Installation Manual2.4 Guidelines for Selection of Equipment LocationsSelect appropriate locations for the Outdoor unit and for the Indoor unit usingthe following guidelines.SU-RA• The SU-RA Outdoor unit should be mounted on a pole and should beinstalled on a rooftop or a side-wall where a direct line of sight with the BaseStation antenna can be established. The higher the unit, the better theachievable link quality.• The antenna (integrated on the front side of the SU-RA Outdoor unit) shouldbe directed towards the Base Station. The unit should be installed in a waythat allows optimal alignment towards the Base Station. The location shouldalso be selected to allow easy access to the unit for installation and testing.SU-RE• The SU-RE outdoor unit should be installed as near as possible to its antenna.• The antenna should be mounted on a pole and should be installed on a rooftop or side wall where a direct line of site with the Base Station can beestablished. The higher the antenna, the better the achievable link quality.• The antenna should be directed towards the Base Station. The antennashould be installed in a way that allows optimum alignment towards the BaseStation. The location of the antenna should allow easy access for installationand alignment.SU-RA/RE• The SU-RA/RE is connected to the SU-NI by means of an IF cable carryingsignaling, control signals and power. The IF frequency is 440 MHz. Themaximum allowed attenuation of the IF cable connecting the Outdoor unit tothe Indoor unit is 15dB and the maximum allowed DC resistance (the sum ofthe DC resistance of the inner and outer conductors) is 1.5 ohm. This allowsfor cable length of up to 30m when using the standard RG 58 cable. If longer cables are required, a cable with lower attenuation and/or DCresistance should be used. Table 2-1 provides details regarding some popularcables such as the RG 58 and RG 213. If the spectral environment is pollutedwith noise in the 440 MHz band, it is recommended to use a higher quality

Aligning the AntennaBreezeACCESS 2.4 Series 19 SU-A/E Subscriber Units Installation Manual4. ALIGNING THE ANTENNANote: Antenna alignment using the RSSI bar display is possible only after theAccess Unit you wish to associate with is operational and the basicparameters were properly configured (see Section 3.2). Otherwise the unitwill not be able to synchronize and associate with the Access Unit. As theRSSI measurement is performed on received frames, its results aremeaningless as long as the unit is not associated with an AU.1. Verify that the Power indication (the Yellow LED of the BSSI bar display)is ON.2. Align the antenna (integrated into the front side of the SU-RA Outdoor unit,or separate if the unit is an SU-RE) to point towards the general direction ofthe base station.3. The RSSI bar display is located on the bottom panel of the Outdoor unit(refer to Figure 2-6). The eight green RSSI LEDs are used for reading theReceived Signal Strength Indication. The higher the number of green LEDsthat are ON, the higher the level of the received signal. Rotate the antennaleft and/or right until you reach the point of maximum RSSI reading. Makesure that at all times, the front of the antenna faces the general direction ofthe base station.4. For proper operation, at least one green LED should be ON. If you cannotreach a point where at least one green LED is ON, try to improve thereception quality by placing the antenna at a higher point or in a differentlocation.Note: In some cases (e.g., when the Subscriber Unit is very close to the BaseStation), the antenna might have to be installed at an appropriate angle, inorder to ensure that it is directed towards the Base Station antenna).5. Tighten the bracket screws (or the U-bolts/metal band), firmly securing theunit or the antenna to the pole.

Appendix BSU-A/E Subscriber Units Installation Manual 28 BreezeACCESS 2.4 SeriesAPPENDIX A. USING TELNETUse the following procedure to connect to BreezeACCESS units via a Telnetsession.1. Connect the PC to the Ethernet port of the unit (or the hub to which the unitis connected) using a straight Ethernet cable. If you connect the PC directlyto a unit that is normally connected to a hub, use a crossed Ethernet cable.You may also connect the PC to any Ethernet port on the network andcommunicate with the unit to be managed via the wired or wireless media.2. Make sure that the IP parameters of the PC are configured to enableconnectivity with the unit.3. Run a Telnet application and use the IP address of the unit to be managed asthe Host Name.4. Set Port to Telnet (this is the default).5. Set Terminal Type to VT100 (this is the default).6. Enter the Service Provider password.7. When the password is recognized, the following message is displayed: You have entered.8. Press Enter, the Breeze ACCESS Monitor is displayed on the screen.To exit the Telnet session, choose Disconnect from the Connect menu.(The session is terminated automatically, after a specific time of inactivitydetermined by the Log-out Timer).
Appendix BBreezeACCESS 2.4 Series 29 SU-A/E Subscriber Units Installation ManualAPPENDIX B. BASIC PARAMETERS• IP Address – Displays the current IP address of the unit and allows entryof a new IP address (4 x 3 digit octets, separated by dots). The default IPAddress is 010.000.000.001.• Subnet Mask – Displays the current subnet mask of the unit and allowsentry of a new subnet mask (4 x 3 digit octets, separated by dots). Thedefault mask is 255.000.000.000.• Default Gateway Address – Displays the current address of the defaultgateway of the unit and allows entry of a new default gateway address (4 x3 digit octets, separated by dots). The default gateway address is000.000.000.000.• ESS ID – The ESSID (Extended Service Set ID) of the unit (up to 32 printableASCII characters). The ESSID is a string used to identify a wireless network. Itprevents the unintentional merging of two co-located wireless networks. AnSU can only associate with an AU that has an identical ESSID. Use differentESSIDs to segment the wireless access network and add security to yournetwork. The default value is ESSID1. Note: The ESSID string is case-sensitive.• Maximum Data Rate – Displays the current maximum data rate, andallows entry of a new value for the maximum data rate. BreezeACCESSunits operate at 1 Mbps, 2 Mbps or 3 Mbps. Under certain conditions(compatibility reasons or range/speed trade-off), you may decide to limitthe use of higher rates. If the quality of the link is not good enough, it isrecommended to decrease the value of this parameters (the higher the daterate, the higher the error rate). The link quality can be estimated based onthe RSSI measurement at the SU, assuming that the RF link budgets are thesame for both directions. Otherwise, there is a high probability that the unitwill have to retransmit many frames several times before temporarilyreducing the data rate. A high number of retransmissions reduces the overall throughput for theselected SU as well as for all the other SUs served by the same AU. If the
Appendix BSU-A/E Subscriber Units Installation Manual 30 BreezeACCESS 2.4 Seriesmeasured RSSI is less than a certain threshold, it is recommended todecrease the Maximum Data Rate in accordance with the following table:RSSI(SU-A/E-2.4) RecommendedMaximum Data RateRSSI > 108 3Mbps95 > RSSI > 108 2MbpsRSSI < 95 1Mbps The default value is 3 Mbps. Allowed values are 1, 2 or 3 Mbps.
