Claims

[Claims for Utility Model Registration] 1. By adding a telephone function to a wireless communication device that can use multiple different transmission and reception frequencies using a weak radio station or a premises radio station under the Radio Law, two-way communication and , a terminal device that enables telephone calls. 2 (a) Using a weak radio station under the Radio Act or a premises radio station, it is possible to conduct two-way communication with multiple groups of terminal devices that can use multiple different transmitting and receiving frequencies, and to use an empty channel. M. which automatically searches and allows multiple calls. C. A. Multi. Channel. A main unit device with a telephone device added to a wireless communication device with an access function. (b) In addition, the main unit device uses a plurality of different subcarriers to transmit data via electric light (power) lines, so that bidirectional calls and telephone calls can be simultaneously used between the main units. The main body device. 3 (c) As shown in Figure 1, the system of the present invention uses a plurality of different transmitting and receiving frequencies from f1 to fn, and has a terminal group capable of bidirectional communication and a plurality of terminals that are the same as the terminal group. It consists of main units 1 to N that use different transmitting and receiving frequencies. (d) Calls between the terminal and the main unit, between the main unit, and between the terminals are carried out by mutual communication using the same plurality of different transmitting and receiving frequencies between the terminal and the main unit, and between the main unit and the main unit. By transmitting using multiple different subcarriers between M. C. A. Multi. Channel. access. Simultaneous multiple calls within the premises are possible. M. characterized by the above. C. A. Simultaneous multiplex calling system within the premises.
