What exactly does Bluetooth do?

Question

Tonight I connected my Samsung Fascinate (an Android phone) and my Sony Vaio laptop via Bluetooth.

My main question is that I've heard that now that this is done, I should be able to use my laptop with Internet access anywhere.

Is this true? If not what does Bluetooth do exactly and do you know how I can get myself free Internet access anywhere?

Thanks!

Answer 1

bluetooth has a various profiles, various ways in which it can work depending on the bluetooth technology you have with your phone and laptop, you will be able to do certain things like for this example you gave above you might be able to get connected to the internet by using the signal of your cellphone to reach out and get information from the internet. ( to make more clearer, you would be using your cellphone as an antenna in a way to grab internet and send it directly to your laptop through the bluetooth connection.



I would be careful doing that because some cell companies dont want you to do that and they will charge if you browse the internet by way of your cellphone via bluetooth to your laptop, hope that helps

Now, about how bluetooth works … Bluetooth Special Interest Group manages and maintains the Bluetooth Standard. IEEE has accepted it as 802.15la standard. Bluetooth was developed with a purpose of creating a single digital wireless protocol, capable of connecting multiple devices and getting over the synchronization issues. It enables short-range wireless communication thus replacing wires connecting the electronic devices. The Bluetooth RF transceiver lies at physical layer. There are 79 bluetooth channels spaced 1MHz apart. A spread spectrum technology is used at the physical layer. Both voice and data transmissions over short distances are possible, creating wireless PANs. A bluetooth device consists of an adapter. A Bluetooth adapter can be built into a device or can be in the form of a card that connects to a device. Instructions are embedded into the device, which enable it to communicate with other devices. When devices come in each other’s radio range, their link managers discover each other. Link management protocol (LMP) engages itself in peer-to-peer message exchange. LMP layer performs link setup and negotiation of packet size. Segmentation and reassembly of packets is done, if needed. Service delivery protocol enables a bluetooth device to join a piconet. A device inquires what services are available with the piconet. Bluetooth GlobalID is exchanged between the devices. Their profiles are matched and a connection is setup. Bluetooth uses frequency hopping in timeslots, which means that the bluetooth signals avoid interference with other signals by hopping to a new frequency after transmission or reception of every packet. One packet can cover up to five time slots. Bluetooth can support an asynchronous data channel, or up to 3 simultaneous synchronous voice channels, or a channel, which concurrently supports asynchronous data and synchronous voice. Bluetooth technology makes use of the concept of master and slave. Devices have to wait until the master allows them to talk! One master and up to seven slaves employ a star topology to form a piconet

Answer 3

actually bluetooth is a specific term. It is an enterprise that created a technology a standard way of exchanging data over short distances approximately up to 50 meters using a short wavelength radio transmission. The reason why you might access internet is that you might capture wireless internet service provider in your area.

You need to tether your phone first.



Google up "Samsung Faschinate tethering" for instructions and videos.



Bluetooth just connects devices to each other so that they can transfer data, but in order to "tether" your Android phone you will need Android 2.2 and a mobile phone plan that actually allows you to tether, else it won't work.

Answer 5

nope no free internet for your pc via bluetooth but some apps let you control your pc via bluetooth.if you want free internet go to places with wifi.

Answer 6

Bluetooth Connect you through wireless stuff for e.g PHONE

Answer 7

I highly doubt it. But you can totally transfer pictures and crap between your phone and laptop now. Sweet!
