Applications for short-range wireless devices include power meters and other remote instrumentation, RFID applications, radio-controlled models, fire, security and social alarms, vehicle radars, wireless microphones and earphones, traffic signs and signals (including control signals), remote garage door openers and car keys, barcode readers ...
Dedicated short-range communications (DSRC) is a technology for direct wireless exchange of vehicle-to-everything (V2X) and other intelligent transportation systems (ITS) data between vehicles, other road users (pedestrians, cyclists, etc.), and roadside infrastructure (traffic signals, electronic message signs, etc.).

Optical wireless communications (OWC) is a form of optical communication in which unguided light is used "in the air" (or in outer space), without an optical fiber. Visible, infrared (IR), or ultraviolet (UV) light is used to carry a wireless signal. It is generally used in short-range communication; extensions exist for long-range and ultra ...
Wireless technologies can be evaluated by a variety of different metrics of which some are described in this entry. Standards can be grouped as follows in increasing range order: Personal area network (PAN) systems are intended for short range communication between devices typically controlled by a single person. Some examples include wireless ...
On September 22, 2020, the SparkLight Alliance was established to formulate the NearLink short-range wireless technology standard. [16]By the end of 2021, the NearLink 1.0 standards were finalized, establishing a core end-to-end architecture that includes the NearLink access layer, basic service layer, and basic application layer.
Nessum wireless communication is called Nessum AIR. It uses magnetic field communication for short range communication. The communication distance can be controlled in the range of a few centimeters to 100 centimeters. Maximum physical speed is 1 Gbps, with an effective speed of 100 Mbps. [9]
The name Wi-Fi is not short-form for 'Wireless Fidelity', [34] although the Wi-Fi Alliance did use the advertising slogan "The Standard for Wireless Fidelity" for a short time after the brand name was created, [31] [33] [35] and the Wi-Fi Alliance was also called the "Wireless Fidelity Alliance Inc." in some publications. [36]
Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 cm (1 + 1 ⁄ 2 in) or less. [1] NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. [ 2 ]
