Laird Technologies announced the release of its enhanced WLM400/402 802.11b/g Wireless LAN modules. These modules are said to offer real throughput many times that of the sub-megabit range for WLAN streaming video and high data rate applications. Based on the Marvell 8686 WLAN chipset, they provide embedded designers both the data throughput and simplicity of a module with embedded drivers and an embedded industrial TCP/IP stack; saving months of embedded firmware development, according to the company. The WLM400 meets FCC/IC standards while the WLM402 meets CE standards. Both modules use a combination of an ARM9 application processor and a flexible light-weight host/device API to provide a streaming channel that can deliver 12 Mbps real data throughput with an 802.11g link and minimal power consumption. Features include the ability to be configured as a transparent bridge between a host and WLAN network, the availability of Enterprise level security, a fully embedded TCP/IP stack, support for 802.11b/g specification, low power operation, and they support antenna diversity.
