Wireless Mobile Networks.

Abstract

Wireless networks have been an essential part of communication in the last century. Over recent years, telecommunications has been a fast-growing industry. Traditionally, first-generation wireless networks were targeted primarily at voice and data communications occurring at low data rates. Then evolution of second- and thirdgeneration wireless systems that incorporate the features provided by broadband. Like most technologies, advances in wireless communications occur mainly through a process of steady evolution for example a big evolution in GSM like GPRS, IS 136 and IS 95 and CDMA is discussed in this thesis. Bluetooth, a new wireless interconnect technology standard, is designed to replace the many cables we need to connect devices to our PCs or networks. Its usage, specification and what is the future of Bluetooth is discussed. A new teleology in third generation mobile networks UMTS is also discussed. Its history and improvement which it needs from other networks are discussed
