Abstract: An adaptive control method of packet length is presented in this paper in order to im-prove the capacity of WPAN. This technique is based on the analysis of system capacity in WPAN standard, which uses FHSS schemes such as Bluetooth. A comparison of system capacities be-tween adaptive packet length and fixed packet length has been made for the case of ACL link and SCO link of Bluetooth. Simulation results show that the adaptive packet length algorithm can im-prove the capacitv of WPAN effectively.

Key words: FHSS, system capacity, wireless personai area network(WPAN), Bluetooth system
