The CE-500 platform provides an optional combined Wireless Local Area Network (IEEE 802.11) and
Bluetooth (Class2) communication module. The Wireless LAN communication is especially suited to high-
speed data transfer over the air, when the Wireless LAN hotspot infrastructure is provided. For
applications that require huge data transactions, Wireless LAN is the most economical way to implement
the solution. Bluetooth communication is used for the Bluetooth-enabled connections with peripherals,
such as mobile phone, audio headset, and printer.
The CE-500 Wireless LAN and Bluetooth Class2 module adopts Marvell’s latest highly-integrated WLAN
and Bluetooth SoC - 88W8688.
NOTE:
The Wireless LAN and Bluetooth capability is a significant power consumer of the
platform. If your solution requires Portable operation of the CE-500 device including
cellular communication, consider the Enhanced battery option while specifying your
device configuration.

The module is compliant with the IEEE 802.11b/g standard and uses DSSS (Direct Sequence Spread
Spectrum), OFDM (Orthogonal Frequency Division Multiplexing), DBPSK, DQPSK, CCK, and QAM
baseband modulation technologies.
In addition to the support of WPA / WPA2, WEP 64-bit, and 128-bit encryption, the module supports the
IEEE 802.11i security standard. The module supports this standard through the implementation of AES
(Advanced Encryption Standard), CCMP (Counter Mode CBC-MAC Protocol), and WEP with TKIP security
mechanisms.
The module also supports IPSec with DES / 3DES / ASE encryption and MD5 / SHA-1 authentication.
For the Chinese market, the module supports WAPI specifications.
For video, voice, and multimedia applications, the AW-GH381 supports 802.11e QoS (Quality of
Service).
