Background
With the large-scale construction of 5G, the high-frequency band propagation loss of a 5G network is large, the existing network has the highest support of 2.7G of the original antenna feeder, and the requirements of 3.5G and above of the 5G network cannot be met. The existing network can not meet the MIMO requirement of the 5G network by the original single antenna feeder, the 5G network generally has a high frequency band of 3.5G and above, and is limited by devices, and the existing network 2G, 3G and 4G network can not be smoothly upgraded to the 5G network. If the feeder supporting 3.5G or more is directly adopted, the cable needs to be redeployed, the cost of the cable is high, and the transmission loss is large. In order to reduce the cost, a 5G frequency shift technology is utilized, so that the original cable can simultaneously support 2G/3G/4G/5G signals, but because optimization processing is carried out on the original cable, corresponding cable replacement is not carried out, and the original cable is easy to break down in the using process.

The output end of the branching module is also connected with a signal amplifier through a feeder line, the output end of the signal amplifier is connected with a plurality of signal antennas, and the number of the signal antennas is the same as that of the frequency shift covering units;
furthermore, the installation positions of the signal antennas are the same as those of the frequency shift covering units, corresponding signal antennas are arranged in a certain distance around each frequency shift covering unit, and the signal antennas are connected with the branching module in the original system through signal amplifiers.
On the basis, the input end of the combiner is connected with a branching module which is used for branching an independent port after the optical fibers output by the 2G/3G/4G module are gathered together and is used for connecting a signal amplifier, so that the signals output by the 2G/3G/4G module are transmitted to other paths besides the branching unit;
furthermore, the branching module is also connected with a control unit for controlling the work of the branching module, when the frequency shift management unit and the frequency shift covering unit work normally, the branching module does not transmit signals to the independent port, the branching module works normally, 2G/3G/4G network signals are transmitted to the combiner, and are combined with the 5G signals and output;
when the frequency shift management unit and the frequency shift covering unit work abnormally, the network signals are transmitted to the original combiner and the independent port, so that the network signals can be output by the signal amplifier.

And a POE external power supply mode is adopted to supply power to the frequency shift management unit.
Because a path of signal is independently added as an auxiliary signal, when the basic communication cannot be ensured when the main signal fails in the 5G frequency shift process, the auxiliary signal can provide the most basic guarantee for the smoothness of the communication.
