XBee-PRO DigiMesh 900 Module, 50 mW, RP-SMA Connector US$49.00

XBee-PRO DigiMesh 900 Module, 50 mW, RP-SMA Connector

Long-range RF connectivity using the DigiMesh protocol

XBee-PRO DigiMesh 900 are long-range embedded wireless solutions providing end-point device connectivity. These modules use the easy-to-deploy DigiMesh networking protocol. This innovative, peer-to-peer network offers added stability through self-healing, dense network operation and support for sleeping routers, extending the operational life of battery-dependent networks. Combining the range advantages of the 900 MHz operating frequency with a fast 156 Kbps data rate to the end node and supporting RF line-of-sight ranges of up to 6 miles (with high-gain antennas), these modules are ideal for extended-range wireless applications requiring increased data throughput.

Part of the XBee family of wireless products, these modules are easy to use, share a common footprint, and are fully interoperable with other XBee products utilizing the same technology. This allows different XBee technologies to be drop-in replacements for each other; you can switch between 802.11, 802.15.4, ZigBee, DigiMesh and proprietary long-range with minimal development time or risk.

Note: This module is certified for use in North America and Australia only. It may not be used in Europe or Japan. Other areas, check local regulations.

DigiMesh Protocol

DigiMesh is a proprietary mesh networking protocol. Its features include:
  • Self-healing — Any node may enter or leave the network at any time without causing the network as a whole to fail.
  • Peer-to-peer architecture — No hierarchy and no parent-child relationships are needed.
  • Quiet protocol — Routing overhead will be reduced by using a reactive protocol similar to AODV.
  • Route discovery — Rather than maintaining a network map, routes will be discovered and created only when needed.
  • Selective acknowledgments — Only the destination node will reply to route requests.
  • Reliable delivery — Reliable delivery of data is accomplished by means of acknowledgments.
  • Sleep modes — Low-power sleep modes with synchronized wake-up are supported, with variable sleep and wake times.
