Question

What is the communication area of bluetooth & Wi-Fi?
​

Answer 1

Bluetooth technology operates in the unlicensed industrial, scientific and medical (ISM) band at 2.4 to 2.485 GHZ, using a spread spectrum hopping, full-duplex signal at a nominal rate of 1600 hops/sec. the 2.4 GHZ ISM band is available and unlicensed in most countries.

Answer 2

❥︎It differs from other radio technologies (mobile phones, radio, and television), in that Bluetooth uses radio waves to transmit over a much shorter distance (164 feet and less, rather than many miles) in what is called a LAN (Local Area Network) or PAN (Personal Area Network), figure 1 .
