Wireless Local area network (wLAN): uses radio waves rather than wires to transmit information across a local area network.
Cellular phones and pagers: provide connectivity for portable and mobile applications, both personal and business.
Cordless Computer Peripherals: connect wirelessly to a computer, such as a cordless mouse, keyboard, and printer.
Satellite television: allows viewers in almost any location to select from hundreds of channels.
WiMAX wireless broadband: enables wireless networks to extend as far as 30 miles and transfer information, voice, and video at faster speeds than cable. It is perfect for Internet service providers (ISPs) that want to expand into sparsely populated areas, where the cost of bringing in cable wiring or DSL is too high.
Security Sensor: alerts customers to break-ins and errant pop files. Its dual sensors record vibration and acoustic disturbances-a shattered window-to help avoid fase alarms.
Personal Digital Assistants (PDA): are small, hadheld computers capable of entirely digital communications transmission.
Smartphone: combines the functions of a cellular phone and a PDA in s single device.
Bluetooth: is a telecommunictions industry specification that describes how mobile phones, computers, and personal digital assistants (PDAs) can be easily interconnected using a short-range wireless connection.
Satellite: is a big microwave repeater in the sky.
Microwave transmitter: uses the atmosphere (or outer space) as the transmission medium to send the signal to a microwave receiver.
Location-based services (LBS): are wireless mobile content services that provide location-specific information to mobile users moving from location to location.
Global Positioning System (GPS): is a constellation of 24 well-spaced satellites that orbit the Earth and make it possible for people with ground receivers to pinpoint their geographic location.
Geographic information system (GIS): is designed to work with information that can be shown on a map.
Wireless fidelity (wi-fi): is a means of linking computers using infrared or radio signals.
Radio Frequency Identification (RFID) technologies: use active or passive tags in the form of chips or smart labels that can store unique identifiers and relay this information to electronic readers.
