Single chip Atheros solution with low power consumption, high
performance & external antenna diversity

Cost effective and Compact Solution
SparkLAN Mini- PCI
Express wireless Module, WPEA-166G, fully supports the features and functional
compliance with IEEE 802.11b/g standard. Delivering data transfer rate up to
standard 54Mbps, WPEA-166G is cost effective module designed with external
antenna and low power consumption. The module based on Atheros AR2425 solution
is a highly integrated single chip that contains MAC/BB/Radio to reduce the size
of module.

Rigid Design for Shock and Vibration Free
WPEA-166G is
the surface mounted type component. The solder join and soldering strength
provide mounting mechanism to secure the WPEA-166G module shock and vibration on
the host system.

Secure Wireless Connection
This mini-PCI Express Module
WPEA-166G with security support of WEP, WPA/WPA2 offers enhanced data
protection.
