Overview
        This module will cover new and emerging wireless 
        technologies, both fixed and mobile. For example, 
        ultra  wideband technologies will enable users to 
        enjoy a wide range of applications, which utilize 
        high  data-transfer  rates.  Next,  the  module  will 
        discuss  Voice  over  IP  (VoIP)  and  WAP  and  the 
        advances  it  offers  to  consumers.  Finally,  the 
        module will discuss the various wireless industry 
        organizations  and  certifications  and  provide 
        several case studies of wireless implementations.

             Ultra-wideband Wireless
                                                                       10-5
    UWB Definition
      The first UWB systems should be able to deliver 
      bandwidth in the 40 to 60 Mbps range, with 
      expectations of very high data transmission speeds, 
      from 100 to 500 Mbps, across distances of 5 to 10 m 
      (16.4 to 32.8 ft). Eventually, UWB could even hit data 
      speeds in the 1-Gbps range, and reach distances of 
      up to 2 km (1.2 miles). 
                                                                       10-6
