Communication speed module will affect the communication distance and receiver sensitivity, the higher the rate, the closer the communication distance. 2. Supply voltage module can affect the transmission power, the operating voltage range, the lower the voltage, the less transmission power. 3. When the module operating temperature change, the center frequency will change, they do not exceed the operating temperature range, without affecting the application. 4. Antenna has a great influence on the communication distance, please use the matching antenna and installed correctly. 5. Installation module can affect the communication distance.
