Abramson‚ a professor at the University of Hawaii‚ developed the world’s first wireless computer communication network‚ ALOHAnet (operational in 1971)‚ using low-cost ham-like radios. The system included seven computers deployed over four islands to communicate with the central computer on the Oahu Island without using phone lines. Definition A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio)‚ and usually

with PCF. Using fragmentation in DCF did not affect the load much and it remains nearly the same. However‚ using PCF resulted in load drop and when we used fragmentation with PCF the load decreased even more. As expected‚ the throughput of WLAN uses PCF was higher than WLAN with only DCF enabled because collisions decrease by using free contention free period. However‚ although the load was lower in DCF_PCF_Frag than this on DCF_PCF but the throughput was higher because of retransmission of fragments
