Power wireless universal communication terminal extension system

An electric power wireless general communication terminal extension system comprises CPE, CPEL, communication and time service. The CPE is placed in a place with good signals outdoors, high-speed wireless access is achieved, and time synchronization is achieved from an NR network or a satellite. A photoelectric composite armored cable is connected with an indoor CPEL, and an independent CPEL is used for supplying power to the CPE by using a safe voltage. The CPEL and the CPE use a standard communication protocol, a PON network is used for being connected with an optical fiber Ethernet, and time synchronization is conducted on the CPEL through the PON network in an equally-divided time slot mode or an IEEE 1588 mode. Except that the time tick CPEL is an independent device, other CPEL can beused as an independent device and can also be used as a secondary equipment embedded module. The independent CPEL is communicated with secondary equipment and has different protocol access capabilities. The CPEL carries out
