Influence on the parameters of the interphone system

system parameter

1) the stronger the transmitter's output power is, the larger the coverage of the transmitting signal is and the farther the communication distance is. But the transmission power can not be too large, the power is too large, not only power consumption, affect the life of power amplifier components, but also strong interference, affect the effect of other people's call, but also produce radiation pollution. Radio management agencies in various countries have clearly specified the transmitting power of communication equipment.

2) the higher the receiving sensitivity of the communication machine is, the farther the communication distance will be.
