WIRELESS COMMUNICATION

• Wireless Communication ,as the name suggests, is a type of data communication that is performed and delivered wirelessly.

• It is the transfer of information between two points that are not connected by an electrical conductor.

WIRELESS COMMUNICATION

• Wireless Communication takes place via electromagnetic waves.

• Examples of wireless technologies include: VSAT, Bluetooth, microwave and Wi-Fi.

BLUETOOTH

DEFINITION OF BLUETOOTH• Bluetooth is a short range and low price

wireless technology originally developed for exchanging data over short distances from fixed and mobile devices, creating personal area networks(PAN).

• Wireless signals transmitted with Bluetooth cover short distances, typically up to 30 feet (10 meters). Bluetooth devices generally communicate at less than 1 Mbps.

Bluetooth

• Bluetooth is a wireless technology that is embedded in the electronic gadgets. It allows us to talk and share information such as music, voice and video wirelessly. Bluetooth technology uses radio waves just like mobile phones, TV and FM radio. The difference between these devices and Bluetooth wireless technologies is the distance.

PARAMETERS OF BLUETOOTH DEVICES

• It is a protocol for exchanging data over short distances from fixed and mobile devices, creating personal area networks.

• There are two important parameters of Bluetooth devices:

• 1.CLASSES• 2.PROFILE

CLASSES• “CLASSES” signifies the distance at which a

Bluetooth connection is possible.

PROFILE• A “Profile” is a type of Bluetooth connection.

The most common are headset(hsp)and hands free(hfp).

• Profiles that enable the device to connect to a wireless headset or hands free.

• Some other Profiles are (OBEX) i.e,( object exchange), which allows transfer of files, contacts and events and (A2DP) i.e, (advanced audio distribution profile),which adds support for streaming of stereo sound.

HISTORY OF BLUETOOTH

• Bluetooth was discovered in 1940.• In 1994,Ericcson a Swedish company created

the Bluetooth technology.• In 1998,five major companies

IBM,INTEL,NOKIA,TOSHIBA AND ERICCSON worked together to connect their products using Bluetooth technology.

• Seeing that the technology worked, companies formed the special interest group (SIG) Bluetooth. This organization is dedicated to keeping this technology. Bluetooth technology is not possessed by a single company, but the members of the Bluetooth SIG all work together to develop the technology.

TYPES OF BLUETOOTH

• THERE ARE TWO TYPES OF BLUETOOTH:• 1. BLUETOOTH DONGLE• 2. BLUETOOTH HEADSET

BLUETOOTH DONGLE• Bluetooth Dongle is simply defined as an

accessory to the computer. By using a Bluetooth dongle a computer can be wirelessly linked to other devices.

• Installing a Bluetooth dongle is easy. Simply insert the CD that came with it .Follow the instructions given and then plug the dongle into a free USB port.

BLUETOOTH HEADSET

• Bluetooth headsets are mainly used with compatible cell phones.

• We can place the Bluetooth headset on our ears and roam freely while talking on phone.

APPLICATION OF BLUETOOTH

APPLICATION OF BLUETOOTH• With Bluetooth being very popular with

wireless, it’s no wonder there are many applications available for the technology. Bluetooth has eradicated the use of cords, cables, adapters and permits the electronic devices to communicate wirelessly among each other.

• 1. Bluetooth's biggest contribution is to provide a phone with a headset that works wirelessly.

APPLICATION• 2. PC OR Laptop which has an enabled

Bluetooth can communicate with each other and update the latest information. This technology has helped in synchronizing the data easily.

• 3.Wireless Mouse and Keyboards are used.• 4.Transfer of files, contact details ,calendar

appointments between devices becomes possible.

APPLICATION

• 5.In game consoles like Sony's play station 3 and PSP go use Bluetooth for there respective wireless controllers.

• 6.IN 2004, released cars like Toyota Prius have hands free call system.

Advantages Of Bluetooth

• 1.Bluetooth devices are wireless.• 2.Bluetooth technology is inexpensive.• 3.Low energy consumption.• 4.Provides range up to 100 meters.• 5.helps to send data and voice easily to other

devices.

Disadvantages Of Bluetooth

• 1.It has a short range.• 2.Lowers the battery life when kept on even

after using.• 3.Less security. It can be hacked easily.

Conclusion

• BLUETOOTH IS A WIRELES TECHNOLOGY THAT HAS BROUGHT CONVINIENCE TO OUR LIFE AS:

• 1.IT REDUSES COST AND USE OF CABLE WIRES.• 2.FURTHER IMPROVEMENTS ARE TO BE MADE

IN TERMS OF POWER REDUCTION AND RANGE.
