This chip is commonly found in smartphones and other NFC devices. Near-field communication ( NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 centimetres (1.6 in) or less. [ 1] NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of ...
The Infrared Data Association ( IrDA) is an industry-driven interest group that was founded in 1994 [ 1] by around 50 companies. IrDA provides specifications for a complete set of protocols for wireless infrared communications, and the name "IrDA" also refers to that set of protocols. The main reason for using the IrDA protocols had been ...
Wireless network technologies. General Packet Radio Service ( GPRS ), also called 2.5G, [ a] is a mobile data standard on the 2G cellular communication network's global system for mobile communications (GSM). [ 1] Networks and mobile devices with GPRS started to roll out around the year 2001. [ 2]
Wi-Fi ( / ˈwaɪfaɪ /) [ 1][ a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks, used globally in home and ...
Wireless power transfer ( WPT ), wireless power transmission, wireless energy transmission ( WET ), or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that ...
wirelesspowerconsortium .com. Qi (pronounced / tʃiː / CHEE; [1] from simplified Chinese: 气; traditional Chinese: 氣; pinyin: qì) is an interface standard for wireless power transfer using inductive charging. The standard allows compatible devices, such as smartphones, to charge their batteries when placed on a Qi charging pad, which can ...
The Certified Wireless USB logo. Wireless USB ( Universal Serial Bus) is a short-range, high-bandwidth wireless radio communication protocol created by the Wireless USB Promoter Group, which is intended to increase the availability of general USB -based technologies. It is unrelated to Wi-Fi and different from the Cypress Wireless USB offerings.
Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access . Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment. [ 1]
