BLUETOOTH USAGE MODELS

Usage models are accompanied by a profile. Profile defines the protocols and protocol features supporting a particular usage model.1. FILE TRANSFER MODEL This usage model offers the ability to transfer data objects from one device to another. Object types include .x1s, .ppt, .wav, .jpg and .doc files, entire folders or directories or streaming media formats. It also offers a possibility to browse the contents of the folders on a remote device.

2. INTERNET BRIDGEUsing this model, mobile phone or cordless modem acts as modem to PC, providing dial-up networking and fax capabilities without need for physical connection to PC.The dial-up networking scenario of this usage model needs a two piece protocol stack. AT-commands are needed to control the Mobile phone or modem and another (PPP over RFCOMM) to transfer payload data.The fax scenario has a similar protocol stack but PPP and the networking protocols above PPP are not used and the application software sends a fax mail directly over RFCOMM.

3 IN 1 PHONE MODEL

Telephone handsets built to this profile may connect to 3 different service providers.1. Telephone may act as Cordless phone connecting to the Public Switched Telephone Network (PSTN) at home or office. This scenario includes making calls via a voice base station, making direct calls between 2 terminals via voice base station and accessing supplementary services provided by an external network.2. Telephones can connect directly to other telephones for the purpose of acting as a “WALKIE-TALKIE” or handset extension. This intercom scenario incurs no additional charges.3. The telephone may act as Cellular phone connecting to the Cellular infrastructure and incurring cellular charges.

ULTIMATE HEADSET MODEL

The headset can be wirelessly connected for the purpose of acting as a remote device’s audio input and output interface. The headset increases the user’s freedom of movement while maintaining call privacy.Example is Headset used with a Cellular headset, Cordless headset, PC for audio input and output.The headset must be able to send AR-commands and receive result code. This ability allows the headset to answer incoming calls and then terminate them without physically maintaining the telephone headset.

CONCLUSION

Bluetooth wireless technology – The technology that propels you into a new dimension in wireless connectivity. It is important to surround yourself with the right kind of people. Bluetooth is a new standard developed by a group of electronics manufacturers, that will allow any sort of electronic equipment to make it's own connections without wires, cables or any direct action from user. It is a rapid growing technology that makes man easy to transfer his electronic equipments from one place to another.It is a technology that not yet completely developed. Hope this will be achieved very soon.
