LoRa Modules - RFM95W


Description

The RFM95W transceivers feature the LoRaTM long range modem which provides ultra-long range wide spectrum communication and interference immunity while minimizing power consumption.
Using Hope RF's patented LoRaTM modulation technique, RFM95W can achieve sensitivity greater than -148 dBm. The high sensitivity combined with the built-in +20 dBm power amplifier provides an industry-leading link budget, making it optimal for any application requiring range or ruggedness. LoRaTM also offers significant blocking and selectivity advantages over conventional modulation techniques, solving the traditional design tradeoff between range, interference immunity and power consumption.
