2. Introduction
Project Name: 802.11 b/g/n wireless card
The T77H262.00 802.11b/g/n module provides wireless modem functionality
utilizing direct sequence spread spectrum and OFDM/CCK technology. This module is
based on Broadcom BCM4319GKUBG P20 solution which is integrated 2.4GHz
IEEE802.11 b/g/n (MAC/baseband/radio), power amplifiers (PA), and power
management unit (PMU).
2.1 Scope
The wireless LAN is compliant to IEEE 802.11b and IEEE 802.11g and IEEE
802.11n standard. The data rate of 802.11b is up to 11Mbps and fallback rates of 5.5, 2,
1Mbps. The data rate of 802.11g is up to 54Mbps and fallback rates of 48,36,24,18,12,9,
6Mbps. The data rate of 802.11n HT20 with 800ns GI is up to 65Mbps and fallback rates
of 58.5, 52, 39, 26, 19.5, 13, 6.5Mbps; the data rate of 802.11n HT20 with 400ns GI is
up to 72.2Mbps and fallback rates of 65, 57.8, 43.3, 28.9, 21.7, 14.4, 7.2Mbps.
The data rate of 802.11n HT40 with 800ns GI is up to 135Mbps and fallback rates of
121.5, 108, 81, 54, 40.5, 27, 13.5Mbps. The data rate of 802.11n HT40 with 400ns GI is
up to 150Mbps and fallback rates of 135, 120, 90, 60, 45, 30, 15Mbps.
