Bluetooth devices intended for use in short-range personal area networks operate from 2.4 to 2.4835 GHz. To reduce interference with other protocols that use the 2.45 GHz band, the Bluetooth protocol divides the band into 80 channels (numbered from 0 to 79, each 1 MHz wide) and changes channels up to 1600 times per second.
A Bluetooth earbud, an earphone and microphone that communicates with a cellphone using the Bluetooth protocol. 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).
Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart [1]) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) [2] aimed at novel applications in the healthcare, fitness, beacons, [3] security, and home entertainment industries.

Continuing with the bedroom example, if Wi-Fi signal strength in there isn't great, the Dot can boost it. All this comes from a little orb that sounds surprisingly decent for its size.
These systems are used to provide wireless access to other systems on the local network such as other computers, shared printers, and other such devices or even the internet. Typically a WLAN offers much better speeds and delays within the local network than an average consumer's Internet access.
The Tile Pro is arguably the best product in Tile's lineup, offering better range and a louder chime than the slightly cheaper Tile Mate and the Tile Sticker. It also has a replaceable battery.
Wireless speakers are loudspeakers that receive audio signals using radio frequency (RF) waves rather than over audio cables. The two most popular RF frequencies that support audio transmission to wireless loudspeakers include a variation of WiFi IEEE 802.11, while others depend on Bluetooth to transmit audio data to the receiving speaker.

WiFi and Bluetooth operate on the 2.4 GHz bandwidth which manages a lot of traffic among devices that consume a lot of power. Other network standards include Bluetooth LE and Thread. Z-Wave has better interoperability than ZigBee, but ZigBee has a faster data transmission rate. Thread and Zigbee operate on the busy Wi-Fi standard frequency of 2 ...
