A whole and useful advisor to WCDMA/UMTS mobile community deployment.After introducing the community structure of the sort of approach, the WCDMA (UMTS) Deployment instruction manual defines the insurance and potential innovations linked to the dimensioning and layout stages. Progressing to a dialogue of the most approach parameters linked to community optimization and detailing optimization innovations for the most companies supported by means of UMTS, and contains the specifics of indoor deployment and HSDPA networks evolution. * Covers all phases from making plans to optimization with enough info as required on a day by day foundation, and thorough reference details for the reader who desires to comprehend the ideas in additional element * proper for day-by-day projects: The technique taken during this booklet is identical to the paintings move of community planner and optimization engineers, permitting such group of workers to simply locate the proper info * Written through the corporate which made CDMA a loved ones identify: QUALCOMM was once the 1st corporation to take advantage of CDMA expertise for mobile software and is a technical chief during this area * in keeping with suggestions: the entire members to this publication were operating in direct interplay with WCDMA operators, in the course of the international, because the early days of WCDMA advertisement deployment * trying to the long run: This e-book addresses the following point of problem that WCDMA operators will face - deployment of indoor structures and HSDPA supplying a whole advent and reference consultant to every thing linked to the existence cycle of a WCDMA/UMTS mobile community, from preliminary dimensioning via to the winning deployment of indoor strategies, or migration to HSDPA, this publication is a must have for community planners and optimization engineers in addition to Telecommunication Engineering scholars.

8 PICH RACH DCH HS-DSCH PRACH DPDCH HS-PDSCH DPCCH HS-SCCH HS-DPCCH Transport channels PHY CPICH Physical channels SCH Physical and transport channels with their relation to the ISO model how they map between different layers. At the Physical Layer, some of the channels, for example Synchronization Channel (SCH) and Common Pilot Channel (CPICH), are not mapped onto any transport channels. This is because these channels only support Physical Layer procedures; no actual data from higher layers is transmitted over them.
8 and Chapter 8 discuss the RF and service optimization processes. 3 Continuous Optimization Once the desired QoS for each service has been achieved and the network is commercially deployed, the process of continuous optimization begins. The early stage of continuous optimization veriﬁes that performance meets expectations after the ﬁrst commercial users are introduced. Differences between the initial optimization and the continuous optimization are likely to be observed because commercial trafﬁc patterns rarely match test trafﬁc patterns.
Link Budgets are further limited by their inability to estimate coverage and capacity trade-offs. Although Link Budgets include a loading term (for Uplink or Downlink), this term usually does not represent a true distribution of trafﬁc over time, service, and 26 WCDMA (UMTS) Deployment Handbook: Planning and Optimization Aspects location. These factors affect loading and are important for understanding the coverage and capacity trade-off. In contrast to how it is commonly done in FDMA/TDMA, network planning for WCDMA examines the Uplink path before the Downlink path, from both the CPICH and the different Radio Bearers.
