As is well-known, the frequency hopping system may have a serious collision problem with the increase of the number of users. Thus a more fast frequency hopping strategy is required to enhanced the collision performance and lead to a higher requirement for frequency hopping rate. In this paper, to overcome this problem a framework of time and frequency system was introduced to satisfied the requirement. The performance of time and frequency-hopping (TH-FH) system for multiple users communication was investigated firstly and then the simulation and measurement results were shown to prove the effectiveness. Based on the frame structure and hopping radio frequency framework the network access with much lower collision probability for multiple users can be realized.
