Problems solved by technology

However, radio interference between adjacent units inhibits this attempt, and even if it does, it is impossible to guarantee speech quality
[0012] (3) When multiple calls are directed to a unit, a call originating from a fixed user fails to seize the radio channel, resulting in failure of voice communication

Embodiment Construction

[0030] A preferred form of a radio communication system according to the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Before describing this embodiment, reference will first be made to figure 1 A radio zone constructed according to the present invention will be described.

[0032] A base station CS-F for fixed subscribers embedded in the telephone network has a communication area with a radius of 3 km. In this case, 37 base stations CS-M (each having a communication range with a radius of 500m) for mobile users are arranged in a communication area with a radius of 500m in a honeycomb form (each cell is hexagonal).

[0033] A plurality of radio equipment SUB-F for fixed subscribers is also arranged in this communication area. Each radio equipment SUB-F includes a telephone. The radio equipment SUB-F is wirelessly connected to the base station CS-F and performs voice and data communication at a frequency of the fixe...

Abstract

A large-capacity WLL base station as a wireless local loop base station is wirelessly linked to a PHS radio station of about channels which accepts the connection thereto of various PHS terminals and a fixed subscriber's terminal which can accommodate a plurality of fixed telephone sets, by use of a PHS band different from that of the PHS terminal. The fixed subscriber's terminal and the PHS radio station are located within one communication area of the large-capacity WLL base station. Thereby, it is provided a radio communication system which provides efficient construction of wireless communications facilities by locating subscribers of a wireless local loop and a base station for microcell-basis, portable communication terminals within a communication area.

Description

field of invention [0001] The present invention relates to a wireless communication system, and more particularly, to a wireless communication system by utilizing a WLL (Wireless Local Loop) system. Background technique [0002] In recent years, the WLL system in constituting communication facilities has attracted attention because it has the following advantages. The WLL system provides for rapid and economical construction of communication facilities. The WLL system can flexibly meet various needs and requirements. WLL-based communication facilities are easy to maintain and difficult to destroy in catastrophic events. [0003] The WLL system replaces conventional wired access devices with wireless access devices, which use metal wire cables. The access device will connect an end user as a user to a node owned and managed by an associated entity. When the radio access device is used, an access network capable of providing a subscriber's telephone service can be construc...
