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

By Ajay R. Mishra

A hugely functional advisor rooted in concept to incorporate the required historical past for taking the reader throughout the making plans, implementation and administration phases 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 positive aspects of the applied sciences that may lead us to the fourth iteration networks. Designing and optimising those complicated networks calls for a lot deeper knowing. complicated mobile community making plans and Optimisation provides radio, transmission and middle community making plans and optimisation elements for GSM, EGPRS and WCDMA networks with specialise in useful features of the sphere. specialists from all the domain names have introduced their studies less than one e-book making it an important learn for layout practitioners, specialists, scientists and scholars operating within the mobile undefined.

A Guide to the Wireless Engineering Body of Knowledge (WEBOK)

The final word reference booklet for pros within the instant undefined the data offered during this publication displays the evolution of instant applied sciences, their effect at the career, and the industry's generally approved top practices. equipped into seven major parts of workmanship, A consultant to the instant Engineering physique of information (WEBOK) complements readers' knowing of: instant entry applied sciences community and repair structure community administration and safeguard Radio frequency engineering, propagation,and antennas amenities infrastructure Agreements, criteria, rules, and rules instant engineering basics Complemented with a lot of references and recommendations for additional examining, the WEBOK is an essential source for an individual operating within the instant undefined.

Software Radio: A Modern Approach to Radio Engineering

I often count on any ebook popping out of a college to be hugely theoretical and math-centric, yet this booklet is neither. it is a transparent exposition of software program radio strategies and concerns, with loads of realization paid to sign new release and processing. not like one other reviewer, i used to be satisfied to work out 70 pages dedicated to clever antennas, due to the fact any multi-protocol transceiver working within the GHz variety goes to want them.

Sample Rate Conversion in Software Configurable Radios

This authoritative, modern source provides a entire evaluation of pattern price conversion (SRC) and its purposes in software program configurable radios. The publication is helping you know the boundaries of possible structures for pattern price conversion, in addition to the bounds of interpolation. You get sound suggestion on determining the right sorts of SRC for particular functions, and counsel in dealing with the trade-off among complexity and the clock fee of a process.

The Radio Spectrum: Managing a Strategic Resource

Radio frequencies became a simple source for the advance of the knowledge society. in truth, radio waves are a compulsory automobile as a way to hold the message to shoppers and a very world wide conversation wishes their houses. Given the industry calls for for increasingly more frequencies, potential need to be came upon to percentage this constrained source such a lot successfully and to continually increase its potency.

Example text

These are explained in detail in the planning sections. 3 Radio Network Dimensioning Dimensioning is the main part of the preplanning phase. In addition to the dimensioning parameters the priority of the parameters also needs to be agreed. The radio network dimensioning parameters have an impact on each other and therefore it is important to decide the emphasis in order to get an optimal dimensioning result within the agreed parameter ranges. It is imperative to agree the network layout, usage of three sector sites or a combination of three sector and omni sites with the operator.

The CN is divided into the CS and PS domains. Circuit switched elements are the Mobile Services Switching Centre (MSC), Visitor Location Register (VLR) and Gateway MSC. Packet switched elements are the Serving GPRS Support Node (SGSN) and the Gateway GPRS Support Node (GGSN). Network elements like EIR, HLR, VLR and AUC are shared by both domains. The Asynchronous Transfer Mode (ATM) is defined for UMTS core transmission. The ATM Adaptation Layer type 2 (AAL2) handles the circuit switched connection and the packet connection protocol AAL5 is designed for data delivery.

The main function of the Core Network (CN) is to provide switching, routing and transit for user traffic. The CN also contains the databases and network management functions. The basic CN architecture for UMTS is based on the GSM network with GPRS. All equipment has to be modified for UMTS operation and services. The CN is divided into the CS and PS domains. Circuit switched elements are the Mobile Services Switching Centre (MSC), Visitor Location Register (VLR) and Gateway MSC. Packet switched elements are the Serving GPRS Support Node (SGSN) and the Gateway GPRS Support Node (GGSN).
