UltraWAVE Micro BTS Installation and Commissioning Guide, Version B 125
Antenna Cabling and Power Verification
10 Record the output power of the TRX on the power meter. This will be displayed
in either Watts or dBm. Your final reading should account for losses at the
cables and connectors, and if used the loss through the attenuator. Table 5-4
provides the allowable readings given a Thruline Watt Meter and the cable
losses referenced in Step 5.
11 To test the reflected power, remove the power sensor from the watt meter, and
put the 10 Watt or 5 Watt sensor into the meter with the arrow pointing
toward the equipment. It is not necessary to disconnect the meter or turn off
the Micro BTS power. You only need to exchange the power sensor and point it
in the direction of the Micro BTS.
If the measured reflected power is equal or less than 4% of the forward power
measured in the previous step, the installation is acceptable. If the
measurement is more than 4%, contact the responsible party for the antenna
and feeder installation. Section 5.3.3 provides more detail about the Voltage
Standing Wave Radio.
12 Complete these steps for each TRX in the Micro BTS.
If a TRX falls out of the above guideline margins, it is still within the operable
tolerance based on the GSM standard or 11.21 test requirement as long as the
power does not go beyond 25% of the maximum value or 20% less than the
minimum value.
For example, if the cable loss is 0.4 dB, the nominal power is 25 Watts and the
measured power is 16 Watts. It is out of the range of Table 5-4, but still
operable because it is above the 14.4 Watts which is the absolute minimum to
operate a Micro BTS according to the GSM standard. If a TRX falls below this
range, contact Customer Service.
