He confirmed that 865-867 MHz is license free.
Obviously you have to make sure your device is within the spectral and power limits specified by the WPC..
Is LoRa legal in India?
LoRa in India To know more about the 865-867 MHz channel regulations, please see the Gazette notification from Wireless Planning and Coordination Wing here. It is illegal to use LoRa in 433 MHz band as it only supports a maximum bandwidth of 10KHz. It also has severe Tx Power limitations.
What is the difference between 315MHz and 433MHz?
Chinese open frequency band is 315Mhz, while Europe and the United States and other countries are 433Mhz, so products exported to the above countries should use 433 remote control; radio remote control commonly used encoding methods are three types, namely fixed code, learning code and rolling code.
How do you check if RF transmitter is working?
Test the circuit by putting the antenna near a source of noise, like a computer monitor, or a motor, or your wireless access point, or your laptop’s WiFi antenna, or any other radio transmitter you have that you know works. Then, put it near your RF transmitter.
What is the frequency used in TPMS?
Most direct TPMS systems use ultra high frequency (UHF) radio in one of the ‘unlicensed’ ISM bands (industrial, scientific and medical) for transmitting the data, often around 434 MHz in Europe and 315 MHz in much of the rest of the world.
Is 121.5 still monitored?
Flight Service Stations will con- tinue to monitor 121.5 MHz, and aircraft pilots are technically still required to monitor this frequency at all times if it’s possible with installed equipment. After all, 121.5 MHz still remains the GARD frequency for airborne emergencies.
What is the range of 433MHz?
Transmitter Operating Voltage: +5V only. Transmitter Operating current: 9mA to 40mA. Operating frequency: 433 MHz. Transmission Distance: 3 meters (without antenna) to 100 meters (maximum)
