Bluetooth will enable users to connect to a wide range of computing and telecommunications devices without the need for proprietary cables that often fall short in terms of ease-of-use. A global specification for wireless connectivity: The Bluetooth SIG Special Interest Group is an industry group consisting of leaders in the telecommunications and computing industries that are driving development of the technology and bringing it to market.

A piconet is a collection of devices connected via Bluetooth technology in an ad hoc fashion. A piconet starts with two connected devices, such as a portable PC and cellular phone, and may grow to eight connected devices.

All Bluetooth devices are peer units and have identical implementations.

However, when establishing a piconet, one unit will act as a master and the other s as slave s for the duration of the piconet connection. Bluetooth technology provides a meter personal bubble that supports simultaneous transmission of both voice and data for multiple devices.

Up to 8 data devices can be connected in a piconet, and up to 10 piconets can exist within the meter bubble. Each piconet supports up to 3 simultaneous full duplex voice devices CVSD.

A Time Division Duplex scheme is used for full-duplex transmission. Bluetooth uses a frequency hopping spread spectrum technique.

Spectrum spreading is accomplished by frequency hopping up to hops per second on 79 channels between 2. Bluetooth radio modules avoid interference from other signals by hopping to a new frequency after transmitting or receiving a data packet. The sophisticated mode of transmission adopted in the Bluetooth specification ensures protection from interference and seeks to insure the security of the data.

Bluetooth operates in the 2. This band provides license-free operation in the United States, Europe, Japan, and most industrialized nations worldwide.

Power transmitted by the Bluetooth: In the Bluetooth specification there are three classes of radios, which are characterized by their output power. Class 3 has a maximum transmit power of 0 dBm 1 milliwatt.

The Bluetooth specification limits the radio output power exactly to that actually required. For instance, if the receiving radio indicates that it is only a few meters away, the transmitter immediately modifies its signal strength to suit the exact range. Furthermore, the radio chip automatically shifts to a low-power mode as soon as traffic volumes becomes low or stops.

The low-power mode is only interrupted by very short signals with the purpose of verifying the established connection. The radio with Bluetooth wireless technology consumes less than a few percent of the power consumed with a modern mobile phone.

The transmission mode is only used as necessary, and always for the shortest possible period of time. Bluetooth technology was designed to be small and inexpensive. Bluetooth technology has no lineof sight requirements making it a potential replacement for infrared ports. Bluetooth can operate through walls or from within your briefcase.

Bluetooth supports a variety of profiles. The following profiles are currently available with Bluetooth.

ABSTRACT 4G TECHNOLOGIES Wireless technology has transformed our lives in many ways. Until very recently, we needed a computer wired to a port, to get online. Even wired telephones are becoming a . Blue tooth specification is a de facto standard, which contains the information needed to ensure that the devices supporting the Blue tooth wireless technology can communicate with each other worldwide.

With the number of wireless communication standards emerging, it is important to understand how each of the standards compare. To understand relative positioning of each wireless standard it is important to first understand there are three primary usage scenarios for wireless connectivity: The emphasis is on instant connectivity between devices that manage personal data or which facilitate data sharing between small groups of individuals Wireless communication adds value for these types of usage models by reducing complexity i.

The emphasis is on a permanence of the wireless connection within a defined region like an office building or campus. This implies that there are wireless access points that define a finite region of coverage.Wireless communication is defined as "electronic products and systems that interact by using electromagnetic energy, to carry information between them, so they can communicate with each other." (Wireless Technology Advisor).

Everywhere we look, the wireless technology is being utilized/5(3). ABSTRACT 4G TECHNOLOGIES Wireless technology has transformed our lives in many ways.

Until very recently, we needed a computer wired to a port, to get online. Even wired telephones are becoming a . Bluetooth is a low cost, low power technology which provides small wireless networks.

The devices with this technology connect each other through short range,ad hoc networks known as piconets. Every time a bluetooth enabled device enter or leave radio proximity the piconets gets established automatically and dynamically.
