XBee S2C 802.15.4 RF modules are built with the Silicon Labs EM357 SoC by Digi International. The design has improved power consumption, support for over-the-air firmware updates and provides an upgrade path to DigiMesh or ZigBee mesh protocols. Also provides a long-range line-of-sight communication for up to 1200 m or 3200 m.
