Introduction

Project Name: 802.11b/g/n (1x1) card based on IC Atheros AR9271(UB91) with QFN package.

802.11b/g/n module provides wireless modem functionality utilizing direct sequence spread spectrum
and OFDM/CCK technology. The typical use model for this embedded device is to allow the host device
to be connected to an 802.11b/g/n 1x1 wireless network with infrastructure mode or to serve as an
ad-hoc (peer-to-peer) data path.

1.1 Scope

The Wireless Atheros AR9271(UB91) available 11n solution in the 2.4-GHz band, compatible with the
IEEE 802.11b standard , 802.11g standard and 11n standard. The 802.11g data rate provides for 54, 48, 36,
24, 18, 12, 9, 6Mbps, and 802.11b data rate provides for 11, 5.5, 2, 1Mbps. In addition, 11n provide 6.5, 13,
19.5, 26, 39, 52, 58.5, 65Mbps for HT20.

1.2 Function

• RoHS and Green Compliant.

• 802.11b/g/n 1x1 based on Atheros AR9271(UB91) IC

• Modulation type: DBPSK, DQPSK and CCK with 802.11b mode. OFDM, QPSK, BPSK, 16-QAM,

and 64-QAM with 802.11g/n mode.

• USB 2.0 Interface, High and Full Speeds supported.

• Module is powered by the host with a 5.0V +/- 10% supply (300mVpp ripple).

• Module’s clock source is provided by the on board XTAL Oscillator of 40 MHz (+/- 10ppm).

• Module connected to motherboard with approximately 30cm cable.

• Unit dependent RF parameters are programmed into each module EEPROM at production test

time by the manufacturer.
