1. Introduction

The J20H069 802.11b/g/n module provides wireless modem functionality utilizing
direct sequence spread spectrum and OFDM/CCK technology. This module is based
on Atheros MCKY AR9374 solution which is integrated 2.4GHz IEEE802.11 b/g/n
(MAC/baseband/radio) and power amplifiers (PA).

1.1 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

802.11b/g/n is backward compatible.
This is 2T2R MIMO device.
This module is installed as a client device in TV platform.
