The current state-of-the-art of broadband millimeter wave systems were presented, along with the vision for wireless LMDS broadband networks as a complement to the existing fiber backbone. Current WLAN developments, and the evolution of WLANs from incompatible low data rate devices to powerful multi-megabit standardized networks were highlighted. Current WLAN standard activities were also presented. Finally, the emergence of Blue tooth, and the concept of a personal area network (PAN) were described. Armed with a high level understanding of the various emerging markets and competing technology choices facing  the wireless telecommunication industry.
