NRF24L01+ / NRF24L01+PA+LNA / E01-ML01DP5 / E01-2G4M27D -Transceiver test 250 Kbps, 1 Mbps, 2 Mbps

2.4 GHz transceivers are being tested: NRF24L01+, NRF24L01+PA+LNA, E01-ML01DP5, E01-2G4M27D with bitrates of 250 Kbps, 1 Mbps and 2 Mbps. Test Purpose: Test purpose: to obtain reliable data on the maximum transmission distance for the above transceivers with bitrate with bitrates of 250 Kbps, 1 Mbps and 2 Mbps. == The test results show that: == 1. Inexpensive noname transceivers have decent characteristics that exceed those stated by the manufacturer. 2. For the specified transceivers, the data transmission distance at 1 Mbit and 2 Mbit bit rates is 75% of the distance at 250 Kbps bit rate. 3. In a deciduous forest, the transmission distance does not exceed 250 metres. 4. SMA-K antennas have a variation in performance depending on the instance. Need to be selected and adjusted.
