1 Purpose
Purpose of this document is to list WiMAX Gen1 System Specifications.
2 Scope
This specification establishes the performance requirements for the WiMAX distributed antenna
system (DAS).
3 Responsibility
LGC Wireless is responsible for maintaining this document.
4 System Level Specification
4.1 Operating Frequencies
WiMAX Gen1 will have two frequency bands. This will allow customer to run Band 1 as main band and
Band 2 as MIMO. Second, it allows customer to run two independent bands for example one could be
sector 1 and other could be sector 2 with same or different frequency.
4.1.1 WiMAX Frequency Band 1:
WiMAX Band 1 has four sub bands that cover Complete WiMAX band from 2496-2690MHz in 60MHz sub
bands.
These tables might change based on marketing requirements.

4.1.2 WiMAX Frequency Band 2:
WiMAX Band 2 has four sub bands that cover Complete WiMAX band from 2496-2690MHz in 60MHz
sub bands.

Note Section 8 and 9 are for internal use only. They are for ATE configuration.
8 Main Hub TDD Requirements:
TDD Duplex port or Simplex ports will be configured in manufacturing based on
customer requirements.
8.1 MH TDD threshold configuration:
Main Hub threshold is configured at ATE. Each band and each Sub Band have different threshold and
memory location.
MH will switch to Downlink at input power of -10dBm. This is configured at ATE with 0dB System gain.
After setting MH gain and calibration threshold, ATE will inject -10dBm signal into MH and measure
detector threshold through A/D and program it into assigned memory location. ATE will measure and
program this value into each sub band it tests.
These steps are repeated for both bands.
9 RAU TDD Threshold Requirements:
9.1 RAU Threshold Configuration
RAU Threshold is set after RAU configuration is done. Each band have different thre shold, and each sub
band has different threshold.
Band 1 setup: RAU Output power is set to -10dBm and Band 1 Downlink Burst Detector output is
measured through A/D and programmed in assigned memory location. Firmware uses this location for
Comparator threshold. These steps are repeated for Band 2.
10 RAU and MH Unit
RAU need to be configured to calibrated Pout of 5dBm from RAU.
MH need to be configured to +5dBm input Power with 0dB system gain.
