hai friends
i am doing my final year project on bluetooth charge can any one give me idea about it……..
i.e charging the mobile phone wirelessly using the bluetooth technology
pls some one suggest me the website where i can gain the knowledge about it…..
Hi Hariharan,
As far as I know bluetooth is a radio frequency based communication protocol. It is designed for low power and short distance communication.
There are microwave wirless battery charging techiques, but how can you use a protocol based wireless data transfer to charge a battery? Bluetooth uses frequency hoped spread spectrum, I think. Inorder to receive such signals, the receiving device (your charger) should be running using an already charged battery!!
Don’t worry, these are my genuine doubts, please correct me if I’m wrong.
@alfred
the bluetooth is a rf signal but it uses emf waves to propagate that means it contains both electrical and magnetical component
i.e. magnetic component (ur data eg.pictures, music….etc) guided by a electrical component so there is a possibilities for the bluetooth charger……
since i dont have enough time i am struggling with this one………..
i have a doubt how the blutooth mouse or keyboard works same principle wat the think is we have to write the coding for that in application layer of the bluetooth header format…….
i am not sure if there is any mistake means pls rectify it……
thank you
Hi Hariharan,
The name Bluetooth charger is really confusing, because bluetooth is nothing but a name of communication protocol using RF tehnology. If you said RF battery charger or Microwave battery charger it would have been OK.
If you think a bluetooth device can perform the function of an RF transmitter for charging a battery, then I doubt it for the following reasons,
– Bluetooth is designed for short distance, LOW POWER communications.
– If you need to operate any electronic component at the receiving end, you need higher transmitting
power in Watts
– A blutooth device will continuously send signals, only when it got connected to another such device,
and there is actual data transmittion between them
– If you think, your battery charger can be made bluetooth capable, then it should have another battery
operating on full charge, powering the battery charger’s bluetooth module alone. And such a system
dosen’t have any advantage over the existing system. Because one can ask, why dont you simply use
that fully charged battey to charge the other one.
Anyway, your project topic is very exciting. And I’m sure you will learn a lot of things during the course of this project.
