XBee DigiMesh 2.4 RF Module, 1 mW, PCB Antenna US$24.00

XBee DigiMesh 2.4 RF Module, 1 mW, PCB Antenna

Wireless connectivity using the DigiMesh protocol

XBee DigiMesh 2.4 delivers end-point device connectivity with a globally deployable 2.4 GHz transceiver. These modules use the innovative DigiMesh networking protocol. This innovative, peer-to-peer protocol offers users added network stability through self-healing, dense network operation and support for sleeping routers, extending the operational life of battery-dependent networks.

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.

The XBee 2.4 DigiMesh modules use the same hardware as the XBee 802.15.4 modules. It is possible to change from one platform to the other by loading different firmware onto the same module.

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.
