Abstract

A transmission level control method in a wireless local loop system capable of suppressing occurrence of an unnecessarily high transmission level, comprises a step of generating a required reception level corresponding to a classification of data, a step of detecting the reception level of data at a receiver side transceiver apparatus, a step of finding a level difference between the detected reception level and the required reception level corresponding to the classification of the related received data, and a step of controlling a change of the transmission level at a transmitter side transceiver apparatus according to this level difference.

Claims

1. A method of transmission level control in a wireless local loop system for transmission of data between transceiver apparatus and another transceiver apparatus via a radio transmission path, comprising:

a step of generating a required reception level corresponding to a classification of said data,

a step of detecting a reception level of said data at a receiver side transceiver apparatus,

a step of comparing the detected reception level and said required reception level corresponding to the classification of the related received data and finding a level difference between the two reception levels, and

a step of controlling a change of the transmission level at a transmitter side transceiver apparatus according to said level difference.
