Wireless Bluetooth

Bluetooth Description

Bluetooth transceivers operate in the 2.4GHz ISM band. The frequency range is 2400MHz to 2483.5MHz [in most countries]. The channel spacing is 1MHz, with an upper and lower guard band. Output power is also specified. Bluetooth uses GFSK [Gaussian Frequency Shift Keying] as its modulation. The symbol rate is 1Msps

The 2.4GHz band is part of the ISM [Industrial, Scientific, and Medical] license-free radio bands. Both Bluetooth and 802.11 operate with in the band. Additional frequencies of the ISM band include the 900MHz band, and 5.8GHz band. The un-licensed ISM band also means that devices need to be short range so that they do not interfere with other devices which may also be using the band.

Bluetooth Interface IC Manufacturers

Of course Bluetooth is a wireless specification, however this site deals with physical electrical interfaces.
But at the same time also the site also covers electronic products, and the manufacture of IC products.
Unfortunately a Bluetooth products covers a wide range of products, but there are few manufacturers of integrated circuits.
