1. What is RFM95W?
The RFM95W is a transceiver module which employs the LoRa long-range modem for highly resilient communication with ultra-long-range spread spectrum capabilities. This module is optimized to deliver outstanding performance in phase noise, selectivity, receiver linearity, and IIP3 while consuming significantly less power than comparable modules. The RFM95W comes in different frequencies, including 868 MHz and 915 MHz, and is suitable for a range of applications that demand long-range wireless communication, such as IoT devices, remote sensors, and other similar applications.
2. What is the range of rfm95?
The effective range of the RFM95 transceiver can differ based on a variety of factors, including frequency, obstructions, antenna type, and power output. As per search results, the RFM95 transceiver is capable of transmitting over distances of up to 2 km in a line of sight configuration with a basic wire antenna. However, the range can be extended up to 20 km with the use of directional antennas and the appropriate settings adjustment. This extensive range can be attributed to the Long Range Modem that facilitates ultra-long range spread spectrum communication and offers high immunity to interference.
