Laird Technologies Releases Enhanced WLM400/402 Wireless LAN Modules
Laird Technologies announced the release of its enhanced WLM400/402 802.11b/g Wireless LAN modules. The enhanced WLM400/402 802.11b/g Wireless LAN modules deliver a new level of performance to WLAN streaming video and high data rate applications. While the majority of wireless modules on the market offer effective throughput in the sub-megabit range, these modules offer real throughput many times that of the sub-megabit range. 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.
“TThe WLM400 meets FCC/IC standards while the WLM402 meets CE standards. Both modules utilize a combination of a powerful ARM9 application processor and a flexible light-weight host/device API to provide a streaming channel that can deliver 12Mbps real data throughput with an 802.11g link and minimal power consumption.
Key features of these modules 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, and low power operation. Furthermore, the modules support antenna diversity, excellent range (1500m in 802.11b), and multiple host interface ports to choose from, including UART, SPI, 10/100 Ethernet, and USB. A hardware development kit is available with a reference hardware design and sample code in the form of a software development kit.
As the only embedded wireless LAN modules providing this level of performance, the WLM400/402 modules are designed to make wireless integration simple with their ultimate throughput, low-power consumption, and ease of use. They are ideal for streaming wireless applications, whether as infrastructure connections or video cable replacements in ad-hoc mode.
