Advanced Cellular Network Planning and Optimisation: 2G 2.5G by Ajay R. Mishra

By Ajay R. Mishra

A hugely functional advisor rooted in conception to incorporate the mandatory historical past for taking the reader during the making plans, implementation and administration levels for every form of mobile network.Present day mobile networks are a mix of the applied sciences like GSM, EGPRS and WCDMA. They even comprise good points of the applied sciences that may lead us to the fourth iteration networks. Designing and optimising those advanced networks calls for a lot deeper knowing. complex mobile community making plans and Optimisation offers radio, transmission and middle community making plans and optimisation points for GSM, EGPRS and WCDMA networks with specialize in useful facets of the sphere. specialists from all the domain names have introduced their reviews less than one e-book making it a vital learn for layout practitioners, specialists, scientists and scholars operating within the mobile industry.Key HighlightsFocus on radio, transmission and middle community making plans and optimisationCovers GSM, EGPRS, WCDMA community making plans & optimisationGives an creation to the networks/technologies past WCDMA, and explores its present prestige and destiny potentialExamines the total variety of power situations and difficulties confronted through those that layout mobile networks and gives suggestion and strategies all subsidized up with real-world examplesThis textual content will function a guide to somebody engaged within the layout, deployment, functionality and enterprise of mobile Networks."Efficient making plans and optimization of cellular networks are key to assure stronger caliber of provider and consumer adventure. additionally they shape the basic beginning for the luck of destiny expertise improvement, making this e-book a useful learn at the highway in the direction of 4G."—Tero Ojanper?, leader know-how Officer, Nokia Networks

Sample text

The UE or ME contains the mobile phone and the SIM (Subscriber Identity Module) card called USIM (Universal SIM). USIM contains member specific data and enables the authenticated entry of the subscriber into the network. This UMTS UE is capable of working in three modes: CS (circuit switched) mode, PS (packet switched) mode and CS/PS mode. In the CS mode the UE is connected only to the core network. In the PS mode, the UE is connected only to the PS domain (though CS services like VoIP (Voice over Internet Protocol) can still be offered), while in the CS/PS mode, the mobile is capable of working simultaneously to offer both CS and PS services.

Coverage maps are made for the planned area and final site locations and configurations. Detailed Planning After the planning phase has finished and the site location and configurations are known detailed planning can be started. The detailed planning phase includes frequency, adjacency and parameter planning. Planning tools have frequency planning algorithms for automatic frequency planning. These require parameter setting and prioritization for the parameters as an input for the iteration. The planning tool can also be utilised in manual frequency planning.

No errors are due to coding and decoding. The same baseland bit sequence can carry several coded information sequences. Spreading codes are also called channellisation codes. This is because spreading codes are used in uplink to separate user and control data (one user) and in downlink to separate common and dedicated channels within a cell (multiple users). 7). Spreading codes must be orthogonal. When selecting a scrambling code to be used, other spreading codes belonging to the same code branch cannot be used.
