System OA&M Capabilities System OA&M Capabilities The InterReach Unison is microprocessor controlled and contains firmware which enables much of the OA&M functionality. Complete alarming, down to the field replaceable unit (that is, Main Hub, Expansion Hub, Remote Access Unit) and the cabling infrastructure, is available. All events occurring in a system, defined as a Main Hub and all of its associated Expansion Hubs and Remote Access Units, are automatically reported to the Main Hub.
System OA&M Capabilities LGC Wireless offers two OA&M packages: AdminManager and OpsConsole. Both run on a PC/laptop. • AdminManager communicates with one Main Hub, and its downstream units, at a time. Using AdminManager connected locally or remotely, you can configure a newly installed system, change system parameters, perform an end-to-end system test, or query system status.

System Connectivity System Connectivity The double star architecture of the Unison system, illustrated in Figure 2-7, provides excellent system scalability and reliability. The system requires only one pair of fibers for eight antenna points. This makes any system expansion, such as adding an extra antenna for additional coverage, potentially as easy as pulling an extra twisted pair.

Maximum Output Power Per Carrier at RAU Maximum Output Power Per Carrier at RAU The following tables show the recommended maximum power per carrier out of the RAU SMA connector for different frequencies, formats, and numbers of carriers. These limits are dictated by RF signal quality and regulatory emissions issues.

Estimating RF Coverage 6.2.1 Path Loss Equation Indoor path loss obeys the distance power law in equation (2): Χ PL = 20log(4πd f/c) + PLSlog(d/d where: • PL is the path loss at a distance, d, from the antenna (the distance between the antenna connected to the RAU and the point where the RF signal decreases to the minimum acceptable level at the wireless device).
For simplicity, Equation (3), Coverage Distance, can be used to estimate the coverage distance of an antenna connected to an RAU, for a given path loss, frequency, and type of in-building environment. 6-14 InterReach Unison Installation, Operation, and Reference Manual CONFIDENTIAL D-620003-0-20 Rev J...

It’s the CDMA equivalent of sig- nal-to-noise ratio (SNR). This figure depends on the mobile’s receiver and the multipath environment.

Connecting a Main Hub to a Base Station Connecting a Main Hub to a Base Station The first consideration when connecting Unison Main Hubs to a base station is to ensure there is an equal amount of loss through cables, combiners, and so on from the base station to the Main Hubs.
• Given these three equations: A1 < 30 dB A1+A3 = 30 dB (in this example) A2+A3 < 10 dB (in this example) we could choose A1=20 dB, A2=0 dB, A3=10 dB 6-38 InterReach Unison Installation, Operation, and Reference Manual CONFIDENTIAL D-620003-0-20 Rev J...
Connecting a Main Hub to a Base Station 6.6.2 Uplink Attenuation The attenuation between the Main Hub’s uplink port and the base station does two things: • It attenuates the noise coming out of Unison. • It attenuates the desired signals coming out of Unison. Setting the attenuation on the uplink is a trade-off between keeping the noise and maximum signal levels transmitted from Unison to the base station receiver low while not reducing the SNR (signal-to-noise ratio) of the path from the RAU inputs to...
Page 106
Typically, the uplink attenuation between the Main Hub and the base station will be the same as, or maybe 10 dB less than, the downlink attenuation. 6-40 InterReach Unison Installation, Operation, and Reference Manual CONFIDENTIAL D-620003-0-20 Rev J...
Connecting a Main Hub to a Base Station 6.6.3 RAU Attenuation and ALC The RAU attenuation and Automatic Level Control (ALC) are set using the OpsCon- sole or AdminManager Advanced RAU Settings command. Embedded within the uplink RF front-end of each Unison Remote Access Unit is an ALC circuit.

Connecting a Main Hub to a Base Station 6.6.3.2 Using the Uplink ALC Setting Uplink automatic level control (UL ALC) circuitry within the RAU provides auto- matic level control on high-power signals in the uplink path. This functionality is required to prevent RF signal compression caused by a single or multiple wireless devices that are in very close proximity to an RAU.

Designing for a Neutral Host System Similar coverage is achieved by setting the transmit power per carrier of the 800 MHz systems to 3 dBm per carrier and those of the 1900 MHz systems to 6 dBm per car- rier. The numbers of RF carriers were selected in order to match subscriber capacity approximately.
