Low Cost, Low Power ISM Band RF Modules

We provide fully tested and ready to run ISM band RF modules pre-programmed with e2Net our proprietary RF mesh networking solution. The modules offer high RF performance at a critical price point. The modules are designed for use in license free applications, covering all major world-wide frequency bands and pre-certified for operation in many countries including North and South America, Europe, India and China. They boast sensitivity down to -115dBm at 4.8kbps and 10dBm output power to provide the perfect balance between power consumption and range; operating at only 30mA in transmit mode, 15mA in receive mode and less than 3uA in low power sleep state.

To supplement the high performance RF hardware, the solution is provided with a complete RF mesh networking stack. The networking stack is a self-forming, self-healing and self-optimising network based on a proprietary routing algorithm, using a central coordinator. Additionally, PC based application software is provided to offer command, control and monitoring of the network with dynamic graphical front end.

The RF modules can be used in any application where a low powered communication network is needed. Some examples of applications are commercial or residential lighting and fixture control, metropolitan lighting control, city-scale security monitoring, and AMR and AMI systems.


The CRF110i is a low cost license free RF networking solution for machine to machine and machine to infrastructure applications. The solution includes a complete RF network stack, with an easy to understand API, and a complimentary PC based library and monitoring solution. The solution includes a complete RF PHY, MAC and Network layer, with an easy to understand API that communicates to a PC based library and monitoring solution. The network is self-forming, self healing and self-optimising, under command of the central control node. In the event of a node or multiple node failure(s) the network will reform around the point of failure and nearby nodes will report the failure point to the central control node.
