Abstract

Wireless is a huge part of the telecommunication technology, which consists of those technologies involving radio waves, infrared waves and microwaves, instead of cables or wires to carry a signal to connect communication devices. The distances involved may be short (a few meters as in television remote control), form a Personal Area Network (PAN), extend to cover a small geographical area (a home, office or a group of building to form the Local Area Network), span cities (ranging from several blocks of buildings to entire cities) to form a Metropolitan Area Network, or cover a broad area (i.e., any network whose communications links cross metropolitan, regional, or national boundaries) to form a Wide Area Network. Wireless technology enables users to physically move while using an appliance, such as a handheld PC, personal digital assistant, paging device, or phone.

WIRELESS COMMUNICATIONS TECHNOLOGIES AND SOLUTIONS introduces many technologies for each one of the above network types. This publication will outline the technologies used for each type, the coverage area provided by each technology, limitation of each technology, and the trend in each one of the above network types. This publication will also evaluate real applications that have been deployed by real vendors and give predictions concerning what application will become very valuable in the next 3-5 years for each technology. Finally, this paper addresses machine technology (M2M), and the different M2M solutions provided in all fields such as Transport and logistics, Retail, Utilities, Security and Construction.

Target audience
  • Wireless Network Operators
  • Wireless Network Application Vendors
  • Any individual interested in wireless technology
