Laird’s 802.11 WiFi Modules feature AT Commands and Web Configuration

Laird Technologies has announced a new range of 802.11 WiFi modules that provide AT commands and web configuration. Key application areas for wireless LAN (WLAN) modules are Machine-to-Machine (M2M) applications and cellular-free telematics. A comprehensive AT commands allows configuration and connection to wireless access points. Another unique feature is the ability for designers to further customize and integrate additional commands. Web and internet designers have the option of a web configuration page that allows the WiFi modules to be configured remotely.

Key benefits of Laird’s 802.11 WiFi Modules:

• Stand alone dynamic module
• Integrated drivers
• Embedded TCP/IP stack
• Backwards compatible with the EZURiO’s Bluetooth Intelligent Serial Modules
• Secure connections
• RoHS Compliant
• FCC and CE approved

These WLAN modules also include an advanced scripting engine, allowing users to write programmable scripts to control the wireless behavior. A default configuration script is included that can be invoked from the M2M application to automatically connect to an access point and middleware or to place it under customer control.

Nick Hunn, Laird Technologies, said:

Most embedded servers are limited to setting up the device parameters, which is not enough for today’s designer… We’ve extended that with functionality to access and embed local information that provides dynamic web content for a new generation of Web 2.0 applications…

Laird Technologies’ wireless LAN processor modules offer a complete solution with a UART interface for data and control, 802.11 drivers, TCP/IP stack, two 10-bit ADCs and 12 GPIO lines as well as a powerful web server.

The WiFi module includes an interpreter running a powerful scripting language that removes the need for any host processing capability. This allows the implementation of complete applications (such as internet-enabled energy monitors, appliances, and healthcare devices) inside the WISM module, drastically reducing production costs of wirelessly-enabled products.

Wireless LAN Module Features

• Pre-approved 802.11b/g radio
• Industrial strength WLAN drivers and TCP/IP stack
• Integrated or external antenna
• Full web server for remote control and access
• Integrated interpreter and powerful wireless scripting language
• Full UART interface
• Secure WEP, WPA, and WPA2 implementation
• Bluetooth coexistence & co-location support
• Low-cost development kit
• Low Power operation – ideal for battery powered applications

Two form factors are available: a compact 25 x 35 mm module that is pin-compatible with the BISM Bluetooth module and a larger module that is pin-compatible with Siemens’ MC55/56 GPRS modules. These combinations allow designers to lay out their printed circuit boards to accommodate a variety of different wireless standards.

Laird Technologies’ wireless product range can be seen at the M2M Expo, Santa Clara, May 20 – 22, 2008.
