While the term wireless network may technically be used to refer to any type of network that is wireless, the term is most commonly used to refer to a telecommunications network whose interconnections between nodes is implemented without the use of wires, such as a computer network (which is a type of communications network). Wireless telecommunications networks are generally implemented with some type of remote information transmission system.
Applications of wireless technology
1) Security systems
2) Television remote control
3) VOIP
4) Cellular telephony
5) WiFi
Benefits of wireless technology
Wireless LANs offer the following productivity, convenience, and cost advantages over wired networks:
" Mobility -- Wireless LAN systems can provide LAN users with access to real-time information anywhere in their organization. This mobility supports productivity and service opportunities not possible with wired networks.
"
" High Installation Speed -- Installing a wireless LAN system can be fast and easy and can eliminate the need to pull cable through walls and ceilings.
" Minimal Cost-of-Ownership -- While the initial investment required for wireless LAN hardware can be higher than the cost of wired LAN hardware, overall installation expenses and life-cycle costs can be significantly lower. Long-term cost benefits are greatest in dynamic environments requiring frequent moves and changes.
" Flexibility: Wireless LAN systems can be configured in a variety of topologies to meet the needs of specific applications and installations. Configurations are easily changed and range from peer-to-peer networks suitable for a small number of users to full infrastructure networks of thousands of users that enable roaming over a broad area.
Common examples of wireless equipment in use today include:
" Professional LMR (Land Mobile Radio) and SMR (Specialized Mobile Radio) typically used by business, industrial and Public Safety entities
" Consumer Two Way Radio including FRS (Family Radio Service), GMRS (General Mobile Radio Service) and Citizens band (CB) radios
" The Amateur Radio Service
" Consumer and professional Marine VHF radios
" Cellular telephones and pagers: provide connectivity for portable and mobile applications, both personal and business.
" Global Positioning System (GPS): allows drivers, captains of boats and ships, and pilots of aircraft to ascertain/find their location anywhere on earth.
" Cordless computer peripherals: the cordless mouse is a common example; keyboards and printers can also be linked to a computer via wireless.
" Cordless telephone sets: these are the limited-range devices, not to be confused with cell phones.
" Satellite television: allows viewers in almost any location to select from hundreds of channels.
