Title: Low speed frequency hopping spread spectrum communication method and radio communication system using the communication method
Inventor: ISHIGAKI SHINJI
IPC: H04W36/06
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of communication efficiency for an entire radio communication system by changing a hopping pattern into a communication fault countermeasure hopping pattern using the frequency of a band other than the frequency that is used for the communication fault countermeasure hopping pattern and accordingly lowering the frequency collision probability. SOLUTION: If a certain radio salve station 12 included in a radio zone Z1 detects a disturbance radio wave sent from a high frequency generator via a disturbance radio wave detection means and cannot perform the radio communication with a radio master station 11, the station 11 notifies by wire a communication management server 40 of the above fact. The serve 40 selects a 1st communication fault countermeasure hopping pattern of the channel data for the relevant station 11 having a communication fault of the zone Z1 and notifies the station 11 of the switching of patterns via a pattern switching means. Meanwhile, the server 40 selects a 2nd communication fault countermeasure hopping pattern of the channel data for a radio master station 21 of a radio zone Z2 that is adjacent to the zone Z1 and notifies the station 21 of the switching of patterns.
