Acceptable Criteria

In order to evaluate the test results, several criteria are reviewed. These criteria are valid for both

LOS and NLOS measurements.

 Processed Sync Signal Strength: For a given test location, +/- 2 dB variation during FTP

 Absolute Sync Signal Strength - Processed Sync Signal Strength: <= to 2 dB variation during

FTP

 SNR values consistent during the FTP for all carriers used:

a. QPSK: >= 11 dB

b. 8 PSK: >= 16 dB

c. QAM 16: >= 19 dB

 UL and DL Packet Error Rates (PER) <= 1%. This will vary according to interference levels,

but may not render the system inoperable.

 Uplink Beamforming Gain: <= 21 dB and >= 16 dB. Perform a comparison of UL and DL,

Beamforming Gain differences should be <= 3 dB.
