Nodes labeled by component databases have sets of successor nodes each labeled by one of the components. These nodes are called AND nodes because in order to process the compound database to termination all of the component database must be processed to termination. so this node here in order toRead More →
What is a variable? • A variable refers to memory location.• It is used to store the value .• Variable is used to give data to the computer for processing .Specifying a variable• In python we don’t need to specify the type of variable because python isa dynamically typed toRead More →
Cellular Concept: Cellular concept deals with reduction of service area by employing high power transmitters that offer high capacity in a limited spectrum allocation. In a geographic region, each base station is assigned with different group of channels from the total number of channels available to the entire system. ThisRead More →

The three subsystems of the cellular system are connected using high speed data links. The mobile unit and cell site are connected through radio link that conveys the voice and signaling information between them. The channel used by each mobile unit for communication is not fixed, the channel can beRead More →
Cellular Telephone System Cellular system accommodate a large number of users over a large geographic area, within a limited frequency spectrum and provide high quality service that is often comparable to that of the land line telephone system. High capacity is achieved by limiting the coverage area of eachRead More →
The evolution of mobile radio communication throughout the world is beneficial. This is because it helps to understand the vast influence of cellular radio and personal communication services over the next future decades. It helps to understand the variation in the evolution of wireless systems, services and technologies due toRead More →
Conventional mobile Systems Cellular mobile system Spectrum utilization is inefficient in conventional mobile system since each channel serves only one customer at a time. The cellular system improves efficiency by three approaches The allocated frequency band is divided into maximum number off channels The allocated frequency band is reused inRead More →
