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
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.
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 ...
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 ...
NFC and Bluetooth are both relatively short-range communication technologies available on mobile phones. NFC operates at slower speeds than Bluetooth and has a much shorter range, but consumes far less power and doesn't require pairing. [90] NFC sets up more quickly than standard Bluetooth, but has a lower transfer rate than Bluetooth low ...
Task Group 6 was formed in November 2007 to focus on a low-power and short-range wireless standard to be optimized for devices and operation on, in, or around the human body (but not limited to humans) to serve a variety of applications including medical, consumer electronics, and personal entertainment.
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.).

IEEE 802.11ad is a protocol used for very high data rates (about 8 Gbit/s) and for short range communication (about 1–10 meters). [59] TP-Link announced the world's first 802.11ad router in January 2016. [60] The WiGig standard as of 2021 has been published after being announced in 2009 and added to the IEEE 802.11 family in December 2012.
