High-Performance 802.11b/g Module

Ideal for all wireless video streaming applications, Laird Technologies’ WLM400 802.11b/g wireless

LAN module delivers a new level of performance to embedded designers requiring the high data

rates available from Wi-Fi networks. The WLM400 offers both simplicity of use and ultimate data

throughput by utilizing a powerful ARM9 application processor that provides a streaming channel

that delivers in excess of 12Mbps real data throughput with a 54Mbps 802.11g link that uses

minimal power consumption.

The only embedded wireless LAN module providing this level of performance, the WLM400 is designed to

make wireless integration simple with its ultimate throughput, low-power consumption, and ease of use.

Based on the Marvell 8686 Wi-Fi chipset, the additional application processor includes a robust, industrial

grade TCP/IP stack and driver implementation to save months of embedded firmware development. It is

ideal for streaming wireless applications, whether as infrastructure connections or video cable replacement

in ad-hoc mode.

FEATURES
