In actual system, it’s a quite attractive character that one can access the channel as he wants. This paper bases on earlier ideal named ISA-MAC(Instantaneous Spectrum Availability MAC) which is promoted and listed in a paper reference [1], and focus on the optimal encode rate and the number of frequency slots of ISA-MAC. Take the probability of no-error channel transmission and the normalized throughput of the system as constrained condition, an analysis come out and be taken as a guide for reality design which is found on the mathematic model and the capability of error detection and correction, and can be adapted to CSMA, ALOHA using FH similar to ISA-MAC which is designed for fulfilling the requirement of accessing at any moment.
