A wireless networking method for multiple portable wireless broadband communication systems

Abstract

The invention discloses a wireless networking method of multiple transportable wireless broadband communication systems. Each transportable wireless broadband communication system comprises an external filter, a base station, a high-power relay terminal, a core network and switching equipment. The wireless networking method comprises that in two adjacent communication systems, the high-power relay terminal of one communication system acts as a terminal of the other communication system to access to the other communication system, thereby being used for realizing communication between the two communication systems; the passband range of the external filter to which the high-power relay terminal is connected is identical to the bandpass range of the external filter connected with a base station RRU in the communication system to which the high-power relay terminal accesses; and in the same communication system, the isolation between transmission of the base station RRU and reception of the high-power relay terminal is greater than or equal to a set first isolation threshold. By applying the wireless networking method, networking can be realized conveniently.

Description

technical field [0001] The present application relates to wireless communication technology, in particular to a wireless networking of multiple portable wireless broadband communication systems. Background technique [0002] With the miniaturization of broadband wireless mobile communication systems such as TDD LTE / WiMAX, in-vehicle or portable broadband wireless communication systems have appeared. A vehicle or several movable boxes are loaded with the base station, core network and application system of the broadband wireless communication system to realize a complete wireless communication system. This communication system is usually used for emergency use. Since one such wireless communication system has only one base station and its coverage is limited, when it is necessary to cover a larger area, it is generally used to connect multiple such systems through optical fiber or other wireless transmission equipment (satellite or microwave). [0003] When using wired (opt...

AI Technical Summary

Problems solved by technology

Using dedicated frequency bands, it is difficult to apply for sufficient spectrum resources

[0005] To sum up, it is difficult to find a wireless relay device with sufficient bandwidth and similar or better receiving sensitivity to LTE

Even with such a system, due to the limited space and power supply capacity in the car, it is difficult to accommodate another set of wireless communication equipment

[0006] Furthermore, if other wireless transmission systems are used to implement wireless relay, multiple vehicle-mounted or transportable LTE systems of the same frequency work together in coordination, requiring complex network planning and high requirements for clock synchronization

In addition, LTE co-frequency networking needs to consider the PCI parameter settings of neighboring cells, otherwise it will cause serious mutual interference

Since the coordination of multiple vehicle-mounted or portable LTE systems is generally temporary, planning and configuration are cumbersome
