WISMC01
802.11b/g Wireless LAN Serial Module
and Device Server
Innovative Technology
for a Connected World
Laird Technologies’ WISMC01 Wireless LAN Processor Modules are the world’s most compact,
feature-rich solutions for designers needing to add wireless connectivity to their products. With
fully integrated drivers and stacks, this complete stand-alone, pre-qualified wireless solution
requires minimum development to implement connectivity to any embedded product.
The WISM range of modules offered by Laird Technologies are not simply Wireless LAN
modules, but complete wireless processor systems capable of stand-alone operation.
The dual-processor design supports an intelligent scripting language that simplifies the
management of the radio control and operation, including full 802.11b/g drivers and
protocols. They also contain a fully embedded TCP/IP stack and web server that provides
dynamic information to an Internet application anywhere in the World.
To simplify the development of wireless LAN applications, Laird Technologies created
UWScript--a language designed to feel much like the BASIC language. Functionality
is enhanced with a range of wireless specific tokens to bring simplicity to embedded
wireless communication. This isolates users from the complexity of the wireless connection
by providing high-level abstract commands. Complete functions, such as finding and
connecting with access points or sending email, are provided as script libraries. These can
be cut and pasted to produce complete working programs in a matter of hours. Using
the sample UWScripts supplied with the Laird Technologies range of WISM modules,
development of 802.11 Wireless LAN becomes a simple development task. Developers can
also access a command line interface, a web configuration tool and a comprehensive set of
AT commands.
