A wireless network is a computer network that uses wireless data connections between network nodes. Wireless networking is a method by which homes, telecommunications networks and business installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. This implementation takes place at the physical level layer of the OSI model network structure. Examples of wireless networks include cell phone networks , wireless local area networks WLANs , wireless sensor networks, satellite communication networks, and terrestrial microwave networks. The first professional wireless network was developed under the brand ALOHAnet in at the University of Hawaii and became operational in June
The information is presented in a logical order within each chapter making it ideal for all levels of reader including researchers involved in modelling and analysis of future networks as well as engineers working in the area. Each chapter starts with introductory material and gradually includes more sophisticated models and mathematical tools concluding with a comprehensive list of references. His areas of interest include radio resource management in wireless mobile IP networks, network management, symbol synchronization in digital communications, automatic decision threshold level control ADTLC and frequency hopping modulation for wireless ad hoc networks. He has vast international experience in the field of telecommunications and has published prolifically on the subject, including three previous books with Wiley.

There is no formal definition for what 4G is; however, there are certain objectives that are projected for 4G. These objectives include: that 4G will be a fully IP-based integrated system. The term 4G is used broadly to include several types of broadband wireless access communication systems, not only cellular telephone systems. While neither standard bodies nor carriers have concretely defined or agreed upon what exactly 4G will be fourth generation networks are likely to use a combination of WiMAX and Wi-Fi technologies. With 4G, a range of new services and models will be available. These services and models need to be further examined for their interface with the design of 4G. Almost all of the systems from this generation were analog systems where voice was considered to be the main traffic.
The most important promise made by the proprietors of 5G wireless technology -- the telecommunications service providers, the transmission equipment makers, the antenna manufacturers, and even the server manufacturers -- is this: Once all of 5G's components are fully deployed and operational, you will not need any kind of wire or cable to deliver communications or even entertainment service to your mobile device, to any of your fixed devices HDTV, security system, smart appliances , or to your automobile. If everything works, 5G would be the optimum solution to the classic "last mile" problem: Delivering complete digital connectivity from the tip of the carrier network to the customer, without drilling another hole through the wall.
