Provider of machine-to-machine (M2M) and Internet of Things (IoT) connectivity products and services, Digi International has announced the immediate availability of the Digi XBee SX 868, a Surface Mount (SMT) radio communication module with interference blocking for noisy wireless environments.
Deployable in several regions throughout the world and with pre-certification for EU countries, the module offers extremely reliable long range, low data rate connectivity for industrial IoT applications such as agriculture, heavy equipment, transportation, and energy/utilities.
The compact SMT module, measuring about 22x34mm, operates in the 863-870MHz frequency band (K, L, M, N, Q/R) and combines tuned Surface Acoustic Wave (SAW) filtering as well as intelligent Listen Before Talk/Adaptive Frequency Agility (LBT/AFA) technology to avoid connectivity issues caused by external radio interference. The patented frequency scan occurs automatically without performance impact by listening to the radio environment before any transmission starts, automatically shifting to a new channel when a interference source is detected.
The Digi XBee SX 868 offers software-selectable data rates up to 80Kbps, strong 128-bit AES encryption for data privacy, point-to-point and point-to-multipoint communication, repeater mode, and the patented DigiMesh protocol option with advanced networking features such as self-healing network configurations, sleeping routers, and high density mesh network configurations. DigiMesh also allows nodes to both route data and enter low power states, optimising the power profile of the entire mesh network.
Digi’s easy-to-use RF management and configuration tool XCTU dramatically simplifies development and deployment of wireless networks based on Digi XBee technology, including robust and scalable Over-The-Air (OTA) firmware update capabilities.
“The Digi XBee SX 868 Sub-GHz radio module delivers continued innovation of a proven technology and strong security in a small, low profile form factor,” said Mike Rohrmoser, Senior Director of Product Management, Embedded Systems and RF Connectivity at Digi International. “It provides sub 2µA sleep modes, excellent receive sensitivity, and exceptional performance with a theoretical line-of-sight range of up to 14.5km using standard antennas. The module’s advanced immunity in challenging wireless environments, including problematic interference issues caused by public cellular networks, makes it the ideal choice for industrial IoT applications demanding reliable communication at all times.”
