In the UK, use of wireless microphone systems requires a Wireless Telegraphy Act license, except for the license free bands of 173.8–175.0 MHz and 863–865 MHz. In 2013 the UK communications regulator, Ofcom, held an auction in which the UHF band from 790 MHz to 862 MHz was sold to be used for mobile broadband services. [23] [24] [25]
A wireless microphone with a non-diversity receiver (a receiver having only one antenna) is prone to random drop-outs, fades, noise, or other interference, especially if the transmitter (the wireless microphone) is in motion. A wireless microphone or sound system using diversity reception will switch to the other antenna within microseconds if ...
Litke’s wireless mike resembled a silver tube with “a microphone at the top, a transmitter in the middle and its battery power supply at the bottom.” [1] It was 6 inches long, 1 inch in diameter, and weighed 7 ounces; the device had a broadcast range of up to a half-mile. Two types of mikes were available: lavalier and hand-held.
The first data application for DECT was Net 3 wireless LAN system by Olivetti, launched in 1993 and discontinued in 1995. A precursor to Wi-Fi, Net 3 was a micro-cellular data-only network with fast roaming between base stations and 520 kbit/s transmission rates.
In the UK, the use of wireless microphone systems requires a Wireless Telegraphy Act license, except for the license-free bands of 173.8–175.0 MHz and 863–865 MHz. These license-free bands are sometimes referred to as "Channel 70" (not to be confused with TV Channel 69, which operated on 854–862 MHz and always required a license from JFMG ...

With this technique is the angle between the microphone axes α = ± 55° = 110° and the distance between the cardioid microphones (microphone basis) is in this case a = 17 cm and gives a total recording angle of 96°. The choice between one and the other depends on the recording angle of the microphone system and not on the distance to and ...
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.
