The Bluetooth adapter basically allows users to exchange data between the system and connected devices, and it’s recommended that the wireless technology be used only over short distances.

The effective range varies depending on propagation conditions, material coverage, production sample variations, antenna configurations and battery conditions. Most Bluetooth applications are for indoor conditions, where attenuation of walls and signal fading due to signal reflections make the range far lower than specified line-of-sight ranges of the Bluetooth products. After the subsequent success of version 4.0, the market introduced Bluetooth version 5.2 on December 31, 2019. Although geared towards low-powered apps, it offers an improved BLE data rate and range - allowing devices to send even more sophisticated data to the end-users. Avishai Wool – אבישי וול". tau.ac.il.

Bluetooth's early incorporation into consumer electronics products continued at Vosi Technologies in Costa Mesa, California, initially overseen by founding members Bejan Amini and Tom Davidson. Vosi Technologies had been created by real estate developer Ivano Stegmenga, with United States Patent 608507, for communication between a cellular phone and a vehicle's audio system. At the time, Sony/Ericsson had only a minor market share in the cellular phone market, which was dominated in the US by Nokia and Motorola. Due to ongoing negotiations for an intended licensing agreement with Motorola beginning in the late 1990s, Vosi could not publicly disclose the intention, integration, and initial development of other enabled devices which were to be the first " Smart Home" internet connected devices. a b c d "Bluetooth Wireless Technology FAQ – 2010".

PXP – the proximity profile – allows a proximity monitor to detect whether a proximity reporter is within a close range. Physical proximity can be estimated using the radio receiver's RSSI value, although this does not have absolute calibration of distances. Typically, an alarm may be sounded when the distance between the devices exceeds a set threshold.

Bluetooth services generally require either encryption or authentication and as such require pairing before they let a remote device connect. Some services, such as the Object Push Profile, elect not to explicitly require authentication or encryption so that pairing does not interfere with the user experience associated with the service use-cases. Pairing often involves some level of user interaction. This user interaction confirms the identity of the devices. When pairing completes, a bond forms between the two devices, enabling those two devices to connect in the future without repeating the pairing process to confirm device identities. When desired, the user can remove the bonding relationship. Ultra HD 4K@60Hz Dual Display] The Mini Computer W11 Pro supports 4K@60Hz Dual HDMI screen output. High-definition true-to-life picture quality brings you an immersive visual experience. You can also easily connect dual monitors at the same time, perform different tasks on the dual screens and monitor the images inside at the same time, reducing unnecessary operating procedures and improving work efficiency. Numeric input devices: Mobile phones are classic examples of these devices. They allow a user to enter a numeric value up to 16 digits in length. Carrie Marshall (30 August 2023).

Historically, the Bluetooth range was defined by the radio class, with a lower class (and higher output power) having larger range. [2] The actual range achieved by a given link will depend on the qualities of the devices at both ends of the link, as well as the air and obstacles in between. The primary hardware attributes affecting range are the data rate, protocol (Bluetooth Classic or Bluetooth Low Energy), the transmitter power, the receiver sensitivity, and the gain of both antennas.
