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.).

Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of
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 ]
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 ...
Despite the intent of the original allocations, in recent years the fastest-growing use of these bands has been for short-range, low-power wireless communications systems, since these bands are often approved for such devices, which can be used without a government license, as would otherwise be required for transmitters; ISM frequencies are ...
They also unveiled "The White Paper for Promotion of SparkLink Short-Range Wireless Communication (SparkLink 1.0) for Industrial Use." [18] [19] On August 4, 2023, Huawei officially unveiled the NearLink short-range wireless communication technology at the Developer Conference, providing a new wireless communication method for HarmonyOS.
