Wireless module automatically changes channels if interference is detected

13 March 2012

Digi International has released what it believes is Europe’s first multi-channel 868 MHz wireless module with Listen Before Talk (LBT) and Adaptive Frequency Agility (AFA) technology, allowing automatic channel changing if interference is detected.  The low cost, low-power XBee 868LP is based on Analog Device’s ADF7023 transceiver and is ideal for energy management, sensor deployments and other wireless networking applications.

The XBee 868 LP features 30 channels for additional interference immunity.  It operates in the 863 – 870 MHz range and offers low power consumption, drawing less than 2uA in sleep mode. The module offers up to four kilometres line-of-sight range and is easy to configure with Digi’s free utility, X-CTU, which reduces development time from months to weeks. The module also supports over the air firmware updates, minimising deployment risks.
Sharing a common hardware footprint, the popular XBee product line offers developers tremendous flexibility and is extremely easy to use.  Pin-compatible and interchangeable multi-channel XBees are available for global deployments, including a 2.4GHz version for the U. and Australia and an 865 MHz module for India.  A 900 MHz version will be available in Q3 2012.
