RN25E-I/RM Application Field and Working Principle

The RN25E-I/RM is a reliable, compact RF transceiver module. It\'s a well-established and widely used in many fields of wireless communication, including Bluetooth or mesh alternatives. It provides low cost and reliable connectivity to a wide range of equipment and devices, from wearables and sensors to smart displays and industrial machines.

The RN25E-I/RM has an immense range of potential applications and uses. It\'s particularly suitable for applications where power, size, reliability, and cost are key factors. It\'s also highly compatible with a variety of software stacks and protocols, including Wi-Fi and Bluetooth.

Working Principle

The RN25E-I/RM works with the Sub-GHz protocol. By default, it operates in the 2.45 GHz ISM band. It contains 200 KHz bandwidth. It supports carriers from 868 MHz to 915 MHz. To be specific, it supports EIR (Enhanced Interference Rejection) with a range from 868.1 to 914.5 MHz.

The RN25E-I/RM can transmit and receive data packets with a maximum rate of 50 Kbps. The standard supported data rate is 1 Mbps to 2 Mbps modes. By using multiple RF channels, it is capable of sending and receiving multiple streams of information.

The RN25E-I/RM transmits using frequency hopping with spread spectrum technology. It can select a multilevel frequency hopping channel spread across the frequency band, thus avoiding the interference of other devices operating in the same band. It also supports low-power transmissions. By using Adaptive Frequency Hopping (AFH) technology, it can reach a low communication power while still maintaining a clear signal.

The RN25E-I/RM receives data from both stationary and mobile sources. It can also handle multiple channels and devices at once. By using advanced signal processing algorithms, it can protect against interference from other devices using the same frequency band.

The RN25E-I/RM is also equipped with a variety of in-built security features, such as end-to-end encryption and access-control based on user IDs. It\'s also easy to implement remote authentication and authorization with the module. It is also Able to communicate over long distances (up to 50 kilometers).

Conclusion

The RN25E-I/RM is a versatile RF transceiver module. It is highly reliable, small and compact, making it suitable for a wide variety of applications. It provides multiple frequencies, data rates, and compatible with a variety of protocols.

It also offers various security features and a long transmission range. It\'s a perfect choice for any application where reliable, low-power, low-cost, and long-distance communication is required.
