NETWORKING: Digi releases 868 MHz wireless modules/devices


Minnetonka, Minn. ” Targeting systems developed for the European market, Digi International has just introduced its XBee-PRO' 868 embeddable RF modules and standalone device adapters, powerful XBee products that provide up to 40 kilometers of RF line-of-sight (LOS) transmission.

According to Larry Kraft, senior vice president of global sales and marketing, Digi International, the products are design for machine-to-machine (M2M) applications in challenging terrain or long-range environments such as remote sensor networks, building automation applications, Automatic Metering Infrastructure (AMI) and Supervisory Control and Data Acquisition (SCADA) systems.

Developers using the XBee-PRO 868 can easily migrate to other XBee solutions including pin-compatible 900 MHz options used primarily in North America, and 2.4 GHz ZigBee and proprietary options available globally.

The XBee-PRO 868 operates on the 868 MHz Short Range Device (SRD) G3 band for Europe providing comparable RF range characteristics as 900 MHz solutions in the U.S.

Where similar 2.4 GHz devices are limited to 10 mW of transmission power, the XBee-PRO 868 is capable of 500 mW of EIRP (equivalent isotropically radiated power). It also provides best-in-class receive sensitivity, rated at -112 dBm.

Additionally, the XBee-PRO 868 features multiple antenna options, over-the-air configuration, strong 128-bit AES encryption for security and an industrial temperature rating of -40 to 85 Celsius. A low-cost 868 MHz mesh solution is also in development.

In addition to OEM RF modules, Kraft said serial and USB device adapters are available and an analog I/O and digital I/O adapter are also in development. These adapters allow developers to use XBee technology through a common hardware interface without the need for embedded development.

XBee-PRO 868 Development Kits are available for an introductory price of $99 until February 2009. XBee-PRO 868 modules are available from $69 in single-unit quantities. XBee-PRO 868 adapters are available from $129 in single-unit quantities.
