RF Transceiver Modules

The ETRX357HR-R8 is a transceiver module developed by Jennic, a global leader in embedded and wireless solutions for the Internet of Things (IoT). It is designed to provide a low-cost, low-power, low profile, and easy to implement radio communication solution for the embedded IoT market. The ETRX357HR-R8 supports IEEE 802.15.4 networks of up to 2.4 GHz, such as Zigbee, 6LoWPAN, Thread, as well as proprietary communication protocols. It has a very good radio performance—high sensitivity and robustness—and is integrated with an efficient 32-bit processor.

Application Field

The ETRX357HR-R8 is often used in industrial applications such as smart home, grid monitoring, medical equipment, and industrial automation. It can also be used in applications that require wireless communication, such as remote control and wireless sensors. In addition, the ETRX357HR-R8 is a good choice for wireless data transmission for consumer electronic systems, such as tablets, cameras, and other small embedded systems.

Working Principle

The ETRX357HR-R8 transceiver module operates on the IEEE 802.15.4 protocol. The 802.15.4 protocol defines a CSMA/CA mechanism for sharing the available bandwidth of the radio channel. Every device that wants to send data continuously monitors the radio channel using the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol. If the channel is free for transmission, the device will transmit its data. If another device is already transmitting, it will wait until the radio channel is free for transmission. The ETRX357HR-R8 also supports encryption to ensure secure communication.

The ETRX357HR-R8 transceiver module has a range of up to 30m and a data rate of up to 250 kbps in the 2.4 GHz band. It has a low power consumption of 1.9mA in receive mode and 6.5mA in transmit mode. The transmit power is up to +14 dBm and the receiver sensitivity is -99 dBm.

Conclusion

The Jennic ETRX357HR-R8 is an ideal wireless solution for a variety of embedded IoT applications. It is a low-cost, low-power, low profile, and easy to implement radio communication module that supports the IEEE 802.15.4 protocol and a range of up to 30m. It has excellent radio performance, a data rate of up to 250 kbps, low power consumption, and supports encryption to ensure secure communication.
