Abstract

An apparatus for setting cell coverage for a radio communication system, includes: first and second portable devices; base station equipment having a switch which loops back a signal from the first portable device to the second portable device in a zig mode; a mode setter for setting the zig mode, the mode setter being located in one of either the first or second portable devices or the base station equipment; and a detector for detecting a received electric field strength from the signal looped back from the first portable device to the second portable device.

Claims

1. An apparatus for setting cell coverage for a radio communication system, comprising:

first and second portable devices;

base station equipment having a switch which loops back a signal from the first portable device to the second portable device in a zig mode;

a mode setter for setting the zig mode, the mode setter being located in one of either the first or second portable devices or the base station equipment; and

a detector for detecting a received electric field strength from the signal looped back from the first portable device to the second portable device.

2. A method of setting cell coverage, using first and second portable devices, base station equipment having a switch for looping back a predetermined signal, and a device for measuring a received electric field strength, comprising the steps of:

setting a mode for setting cell coverage;

effecting a call from the first portable device to the second portable device;

looping back the signal from the first portable device to the second portable device in the base station equipment via the switch;

detecting a received electric field strength needed for setting cell coverage from the signal looped back to the second portable device via the received field strength measuring device.

3. An apparatus for setting cell coverage for a radio communication system equipped with base station equipment and first and second portable devices, comprising:

a mode setter for setting a zig mode, the mode setter being located in one of either the first or second portable devices or in the base station equipment; and

a switch, disposed in the base station equipment, for looping back a signal from the first portable device to the second portable device when said mode setter sets the apparatus to the zig mode.

4. An apparatus for setting cell coverage for a radio communication system comprising:

a radio transmitter/receiver for receiving and transmitting radio signals;

first and second portable devices for transmitting and receiving radio signals;

a cordless telephone second generation and common air interface baseband circuit;

a radio interface circuit disposed between said cordless telephone second generation and common air interface baseband circuit and said radio transmitter/receiver;

a controller, having a memory, and connected to said cordless telephone second generation and common air interface baseband circuit and said radio interface circuit;

an S interface circuit connected to said controller; and

a switch connected between said S interface circuit and cordless telephone second generation and common air interface, and also connected to said controller;

said switch being controlled by said controller to loop back a signal from said first portable device to said second portable device; and

a detector for detecting a received electric field strength from the signal looped back from first portable device to said second portable device.
