METHOD AND SYSTEM FOR RADIO TRANSMITTING STOCK PRICE INFORMATION

摘要

PROBLEM TO BE SOLVED: To provide stock price information radio transmission method and system capable of evading a transmission collision without executing carrier sensing and improving line reliability without increasing radio base station installing places. SOLUTION: Each of plural radio base stations executes hopping for switching a transmission frequency in each fixed time in accordance with the previously determined initial value of transmission frequency and a hopping pattern so as not to coincide with the transmission frequency of other radio base stations and transmits a stock price message and hopping channel information to be the information of transmission frequency to be hopped next as a radio packet by the hopped transmission frequency and a radio terminal station receives the radio packet while switching receiving frequency in each fixed time in accordance with the received hopping channel information.
