Bluetooth wireless technology is a short-range communication system intended to provide connectivity of voice and data between information appliances. Initially designed to operate with a peak data rate of 1 Mb/s, the Bluetooth core specification has evolved to support 2 Mb/s and 3 Mb/s peak data rates with the introduction of the enhanced data rate (EDR) feature. The Bluetooth Special Interest Group (SIG), chartered to advance and promote Bluetooth wireless technology, has defined a test specification for conformance testing of the RF layer including the EDR mode. This article is intended for the Bluetooth EDR operation and test. Included is a brief discussion of the market needs that drove the evolution of the core specification from v1.0 to v1.2 and continuing on to v2.0+EDR. An in-depth examination of the Bluetooth EDR standard will be provided which includes new test cases for provisional testing of transmitter and receiver designs.

Wireless communication is one of the most active areas of technology development of our time. This development is being driven primarily by the transformation of what has been largely a medium for supporting voice telephony into other services, such as the transmission of video, image text and data. The traditional resources that have been used to add capacity to wireless systems are radio bandwidth and transmitter power. Two resources area among the most severely limited in the deployment of modem wireless network. The focus of the article is to provide a detailed discussion on the performance of cellular radio systems. It also provides future directions and innovations of the cellular mobile technology.
