  ZigBee评估套件支持2×2 MIMO

  随着以指数速度增长的机器对机器(M2M)应用程序的增长,竞争将取决于哪些无线协议占据了这个空间。和以往一样,解决办法取决于问题。对于长途无线2G蜂窝可能最适合的议案。短距离无线Wi-Fi®,蓝牙®,和一些802.15.4 ZigBee协议–是其中最重要的–都可以工作。然而,如果您的应用需要超低功耗但工作在一个环境里连接的可靠性可能有问题,Atmel的2.4 GHz reb233smad评估套件(见图1)值得一看。

  The REB233SMAD-EK contains two radio extender boards (REB) based on the Atmel AT86RF233 2.4 GHz RF transceiver; two controller base boards (CBB) built around the ATxmega256A3 MCU; two USB adaptors with cables for programming the MCU; four SMA antennas; plus batteries and a Quick Start Guide. The wireless boards plug into the MCU boards, enabling you to do an immediate range test of two complete wireless nodes using a simple ready to run range measurement application.

  The kit is designed to be a complete platform for designing and prototyping ZigBee-compliant wireless applications such as ZigBee SmartEnergy and Home Automation systems. To that end, Atmel supplies its BitCloud™ stack – a ZigBee® PRO certified platform – and the BitCloud Profile Suite.
