How far is the transmission distance of the EFR32 SOC Arm cortex 4 & high sensitivity DSSS transceiver module

2021-04-21

The EFR32 module is our latest low-power high-performance SOC wireless transceiver module, which is mainly used in industrial automation, electronic shelf signs, home and building automation and security. So how far is its transmission distance? Next, follow the editor of NiceRF to announce together.

 

First prepare the tools: two EFR32 DEMO function demonstration boards, two EFR32 extension boards (EFR32 wireless modules have been welded on them), two 868MHz frequency rod antennas (SW868-ZT48), 6 batteries: 1.5V voltage (each battery).

Next, use the DEMO function demonstration board of the SOC wireless transceiver module EFR32 for distance testing, power on the two EFR32 DEMO boards (power supply voltage is 4.5V), and the Demo board is regulated to 3.3V. Set the transceiver frequency of the two DEMO boards to 868MHz, transmit power 20dBm, data rate (DR) to 1.2Kbps, frequency deviation (FD) to 12KHz, bandwidth (BW) to 9.6KHz, and one of the DEMO boards is adjusted to the Master terminal. The other is adjusted to the Slave end for two-way communication.

Due to the relatively long transmission distance, the test environment is G107 (Guangshen Highway), Baoan District, Shenzhen. After actual measurement, the transmission distance of the SOC wireless transceiver module EFR32 is 4.3Km.
