bluetooth circuit in mobile phones


Posted on Feb 7, 2014

Bluetooth is an open wireless device technology standard for exchanging data over short distances from fixed and mobile devices(using short wavelength radio transmissions), creating personal area networks (PANs) with high levels of security. The Bluetooth baseband protocol is a combination of circuit and packet switching. Slots can be reserved for synchronous packets.

Each packet is transmitted in a different hop frequency. A packet nominally covers a single slot, but can be extended to cover up to five slots. Bluetooth can support an asynchronous data channel, up to three simultaneous synchronous voice channels, or a channel, which simultaneously supports asynchronous data and synchronous voice. Since we are talking about mobile phones here, it is much more really great to know how really bluetooth circuit works on cell phones circuit Isn`t it nice to know, so that we can easily managed how to fix it since it is our main reason in this tutorials by learning how to repair damaged cell phone devices. In mobile phones Bluetooth problems also occurs when the bluetooth circuit is damaged, Some new cell phone techie find it hard to fix bluetooth for not knowing how the circuit works. Okay, lets tackle it for a while in just very simple explanation so that all of those without any background in electronics might can catch up too, and then we can use it in our everyday job on GSM field. Figure the bluetooth circuit block diagram below for it shows how the Bluetooth Circuit works according to each corresponding parts or components that is being connected to it. The bluetooth transceiver module is packed into chip or IC (integrated circuit), this chip needs a certain power supply to make it work. All the data that has been transmit (send) and receive from the bluetooth antenna and bluetooth RF...
