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.). [1]
Short range agent communications (SRAC) are one-way or two-way short-range wireless communications used for intelligence purposes. This communications technology became possible with the arrival of the transistor and small scale integrated circuits.
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.

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 ...
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 up to 10 metres (33 ft).
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 ...
Some examples of node devices – door locks, smoke detectors, motion detectors, remote controls, gas and electricity meters, baby monitors, elderly care, etc. ULE communication range is among the longest in the short range wireless communication technologies: over 50 meters in buildings and up to 300 meters in the open air.
