ABSTRACT
WPANs (Wireless Personal Area Networks), WLANs (Wireless Local Area Networks), WMANs (Wireless Metropolitan Area Networks), and WWANs (Wireless Wide Area Networks) operate at various rates and levels of complexity; feature a multiplicity of architectures, protocols, and topologies; and vary in size and capacity. As with cellular networks, these configurations provision links to Web resources and narrowband and broadband network applications such as e-mail, E-banking transactions, distance education, and telehealthcare treatment via RF (Radio Frequency) waves in free space, thus eliminating requirements for fixed wireline connections.
