What is the difference between rf and wireless

In the mobile phone market Bluetooth wireless technology connects headsets to phones, giving the user a true hands-free experience and a greater sense of freedom.

Bluetooth is safe. It utilizes radio signals times weaker than the standard wireless technologies used by mobile phones. It is secure too, so once a connection has been made no-one can listen in and there is no interference from other Bluetooth devices either. It works over distances up to 33 feet and connected units do not need to have line of sight. Headsets are connected to phones using a procedure called "pairing.

Bluetooth technology runs on 2. Most Bluetooth headsets run with Class 2 Bluetooth, which provides a range of up to 33 feet. There are a couple of Class 1 Bluetooth headsets that have ranges up to feet. Bluetooth headsets are generally small and worn on or in the ear. The useful links to difference between various terms are provided here. Both RF and Microwave are used to represent frequency ranges in the electromagnetic spectrum.

Both are used for many similar as well as different applications. RF is the short form for 'Radio Frequency' signal. Following table-1 mentions frequency and wavelength of both of these terms. EM spectrum has been classified into eight regions based on radiation intensity. The major divisions are into radio spectrum and optical spectrum.

Click to expand Wi-Fi Alliance is a consortium of separate and independent companies agreeing to a set of common interoperable products based on the family of IEEE Now hang on a mo here Wi-Fi, as I mentioned above, is a standard.

A standard protected by lawyers. Wi-Fi operates on a radio frequency - RF for short. So, I suppose there may be some confusion here. If we're going to talk 'how does wifi operate' then yes, wifi and rf are the same things. If we're going to talk 'can I label this device wifi and rf the answer may be yes Wait, hang on I'm confusing myself Answer any clearer now? Oh well, who gives a flying one anyway? Ultimately low-frequency radio waves display low signal attenuation, making them suitable for long-distance communications, whereas high-frequency radio waves tend to display high signal attenuation and is suitable for short-distance communications.

Both are affected by obstacles such as walls and other matching radio frequencies, therefore you have a better chance of reaching the distances you need using low-frequency radio technology. When the connection is lost from the WiFi router, then the transmitter battery power will be drained trying to re-establish a connection to the router.

Typical wireless systems using independent radio technology have wireless radio ranges of around meters; whereas Hanwell wireless technology using Hanwell Pro or Hanwell IceSpy line of sight can reach up to 3, meters.
