A communication method for learning adaptive 2.4G frequency band wireless frequency hopping

Abstract

The invention discloses a learning type adaptive 2.4G frequency band radio frequency hopping communication method specifically comprising the following steps of 1, judging a communication condition, performing slow frequency hopping when the condition that communication is normal is determined, judging whether communication frequency is synchronous, and if the communication frequency is asynchronous, performing error processing; and 2, when condition that an error occurs in communication is determined, performing fast frequency hopping, wherein a receiver and a transmitter are synchronized within a short time, the receiver and transmitter select proper communication channels, and thus the communication is recovered. According to the method provided by the invention, related parameters during a communication process are recorded and analyzed, and the most proper next communication channel is selected, so that basic compunction such as synchronous linking, high communication speed, periodical change of the communication channel and fast recovery of an error are kept, capacities of resisting interference among the same kind of equipment and avoiding the interference channel are also increased, and thus the different types of equipment work harmoniously in the same frequency band.

Description

technical field [0001] The invention relates to the field of 2.4G wireless communication, in particular to a learning type self-adaptive 2.4G frequency band wireless frequency hopping communication method. Background technique [0002] Wireless products, that is, electronic products using radio technology, should include a wireless signal transmission and receiving system, such as mobile phones, wireless Internet access devices, cordless phones, wireless walkie-talkies, etc. in daily life, which are wireless devices. 2.4G wireless technology, its frequency band is between 2.405GHz-2.485GHz (science, medicine, agriculture), so it is called 2.4G wireless technology for short. This frequency band is a free frequency band stipulated by the international community, and there is no need to pay any fees to relevant international organizations. This provides the necessary favorable conditions for the development of 2.4G wireless technology, and 2.4G wireless technology is different...

AI Technical Summary

Problems solved by technology

[0003] Some of the current 2.4G wireless products have fixed frequency communication; or there is interference to other devices in the same frequency band during frequency hopping, making the interfered device unable to work normally; or they can actively avoid the occupied channels, but in the communication process When an error occurs in the system, it takes a long time to recover, which makes the communication process unsatisfactory and the product experience decline
