On Tuesday, Digi International released the XBee 865LP, a multi-channel 865 MHz wireless module that features up to 10 channels for interference immunity. The module can improve network performance in "noisy" wireless environments and offers twice the range of other modules, says the company. The low-power module is based on Analog Device's ADF7023 transceiver and can be used for energy management, sensor deployments and other wireless networking applications.
"When numerous 865 MHz devices are running simultaneously, increased risk of radio interference exists," said Larry Kraft, senior vice president of global sales and marketing, Digi International (Minnetonka, Minn., USA).
The XBee 865LP features Listen Before Talk and Adaptive Frequency Agility technology allowing the module to automatically change channels if interference is detected. The module listens to the radio environment before transmitting and automatically shifts to a new channel when interference is detected, says Digi. This patent-pending frequency scan occurs automatically and in a matter of microseconds, so there is no impact on performance.
The XBee 865 LP operates in the 865-867 MHz range and offers low power consumption drawing less than 2uA in sleep mode, according to the company. The module offers up to four kilometres line-of-sight range and is easy to configure with Digi's utility, X-CTU, which reduces development time from months to weeks. The module also supports over the air (OTA) firmware updates further minimizing deployment risks.
The XBee 865LP module is available now for less than $15 in 10,000 quantities. Development kits are available now starting at $199 per kit, says Digi .
