What is the difference between mobile and wireless? The terms "mobile" and "wireless" are often used interchangeably but in reality, they are two very different concepts applied to modern computing and technology. Mobile is a word that is commonly used to describe portable devices.

Spectrum management Light, colors, AM and FM radio, and electronic devices make use of the electromagnetic spectrum. This determines which frequency ranges can be used for what purpose and by whom. In the absence of such control or alternative arrangements such as a privatized electromagnetic spectrum, chaos might result if, for example, airlines did not have specific frequencies to work under and an amateur radio operator were interfering with the pilot's ability to land an aircraft.

They can be used within range of the mobile telephone site used to house the equipment required to transmit and receive the radio signals from these instruments. For all wireless Internet access, see Wireless broadband. For mobile wireless Internet, see Mobile broadband.

Wireless data communications allows wireless networking between desktop computerslaptopstablet computerscell phones and other related devices. The various available technologies differ in local availability, coverage range and performance, [12] [13] and in some circumstances users employ multiple connection types and switch between them using connection manager software [14] [15] or a mobile VPN to handle the multiple connections as a secure, single virtual network.

Wi-Fi is a wireless local area network that enables portable computing devices to connect easily with other devices, peripheries, and the Internet. Wi-Fi has become the de facto standard for access in private homes, within offices, and at public hotspots.

Mobile-satellite communications may be used where other wireless connections are unavailable, such as in largely rural areas [22] or remote locations. This allows us to detect relevant quantities, monitor and collect data, formulate clear user displays, and to perform decision-making functions [24] Wireless data communications are used to span a distance beyond the capabilities of typical cabling in point-to-point communication and point-to-multipoint communicationto provide a backup communications link in case of normal network failure, to link portable or temporary workstations, to overcome situations where normal cabling is difficult or financially impractical, or to remotely connect mobile users or networks.

Peripheries[ edit ] Periphery devices in computing can also be connected wirelessly as part of a Wi-Fi network or directly by optical infer-red, Bluetooth or Wireless USB.

Originally these units used bulky, highly local transceivers to mediate between a computer and a keyboard and mouse; however, more recent generations have used small, higher-quality devices.

A battery powers computer interface devices such as a keyboard or mouse and send signals to a receiver through a USB port by the way of an optical or radio frequency RF receiver. A RF design makes it possible to expand the range of efficient use, usually up to 10 feet but distance, physical obstacles, competing signals, and even human bodies can all degrade the signal quality.

Wireless energy transfer Wireless energy transfer is a process whereby electrical energy is transmitted from a power source to an electrical load Computer Load that does not have a built-in power source, without the use of interconnecting wires.

There are two different fundamental methods for wireless energy transfer. Both methods utilize electromagnetism and magnetic fields. The MBAN works by sending low powered wireless signals to receivers that feed into nursing stations or monitoring sites.
