1. INTRODUCTION

GW52 is built on the Marvell® 88W8787 low-cost highly-integrated IEEE

802.11b/g/n MAC/Baseband/RF WLAN and Bluetooth Baseband/RF system-on-chip

(SoC).The module supports IEEE 802.11n with maximum data rates up to 72Mbps

(20 MHz channel) and 150 Mbps (40MHz), 802.11g payload data rates of 6, 9, 12, 18,

24, 36, 48, and 54 Mbps, as well as 802.11b data rates of 1, 2, 5.5 and 11 Mbps for

WLAN operation.

For Bluetooth operation, the module supports Bluetooth 3.0 + High Speed (HS)

(also compliant with Bluetooth 2.1 + EDR).

For security, the 88W8787 supports the IEEE 802.11i security standard through

implementation of the Advanced Encryption Standard (AES)/Counter Mode

CBC-MAC Protocol (CCMP), and Wired Equivalent Privacy (WEP) with Temporal Key

Integrity Protocol (TKIP) security mechanisms.

The module also supports Internet Protocol Security (IPsec) with DES/3DES/AES

encryption and MD5/SHA-1 authentication as well as 802.11e Quality of Service

(QoS). The module supports dual SDIO host interface for connecting the WLAN and

Bluetooth to the host processor. For Bluetooth application the high-speed UART (up

to 4MB/s, PCM/Inter-IC Sound (I2S), are supported too.

For better throughput of WLAN/BT the module provide different RF paths for WLAN

and Bluetooth for two antennas. By using of two antennas with enough decoupling it

enables to do without coexistence.
