Narrow Band Evaluation Kit (NBEK) can be used to evaluate all Narrow Band Multi-channel and Single frequency DIL version modules. Radio modules can be assessed for their suitability in terms of operating range, functionality, reliability and robustness in a multi-user environment with several other modules on different channels. Built in Control44, I1200 modes allow user to evaluate the performance of Radiometrix narrow band modules in a typical Remote Control and data transmission application in an industrial environment.
