By Jaana Laiho, Achim Wacker, Tomáš Novosad

Radio community making plans and Optimisation for UMTS, moment Edition, is a finished and entirely up to date creation to WCDMA radio entry know-how utilized in UMTS, that includes new content material on key advancements. Written by means of major specialists at Nokia, the 1st version fast confirmed itself as a best-selling and hugely revered booklet on how one can size, plan and optimise UMTS networks. This priceless textual content examines present and destiny radio community administration concerns and their impression on community functionality in addition to the appropriate means and insurance enhancement equipment.

In addition to insurance of WCDMA radio entry know-how utilized in UMTS, and the making plans and optimisation of the sort of procedure, the carrier keep watch over and administration notion in WCDMA and GPRS networks also are brought. this is often an outstanding resource of data for these contemplating destiny mobile networks the place caliber of carrier (QoS) is of paramount importance.

Key gains of the second one version include:

  • High-Speed Downlink Packet entry (HSDPA) – actual layer, dimensioning and radio source management
  • Quality of carrier (QoS) mechanisms in community for carrier differentiation
  • Multiple enter – a number of Output (MIMO) technology
  • Practical community optimisation examples
  • Service optimisation for UMTS and GPRS/EDGE capability optimisation
  • The ‘hot subject’ of provider keep an eye on and administration in WCDMA and GPRS networks, that has advanced because the first edition

Companion web site includes:

  • Figures
  • Static radio community simulator carried out in MATLAB®

This textual content may have speedy attract instant operators and community and terminal brands. it's going to even be crucial analyzing for undergraduate and postgraduate scholars, frequency law our bodies and all these drawn to radio community making plans and optimisation, rather RF community structures engineering professionals.

Sample text

MAC provides an efficient use of transport channels; based on the instantaneous source rate(s), it selects the appropriate transport format (TF) within an assigned transport format set (TFS) for each active TrCH. The transport format is selected based on the transport format combination set (TFCS), which is assigned by the RRC protocol and produced by the admission control in the RNC when a radio access bearer is set up or modified [5]. The functionality of the MAC layer includes priority handling between data flows of one connection (selection of a TFC for which high-priority data is mapped onto L1 with a 'high bit rate' TF); priority handling between UE(s) by means of dynamic scheduling and identification of UEs on common transport channels (in band identification).

Operators face the following challenges in the planning of 3G networks: • Planning means not only meeting current standards and demands, but also complying with future requirements in the sense of an acceptable development path. • There is much uncertainty about future traffic growth and the expected proportions of different kinds of traffic and different data rates. • New and demanding high bit rate services require knowledge of coverage and capacity enhancement methods and advanced site solutions.

Each block represents an instance of the corresponding protocol. The dashed lines represent the control interfaces through which the RRC protocol controls and configures the lower layers. The service access points between the MAC and physical layers and between the RLC and MAC sub-layers provide the transport channels (TrCHs) and the logical channels (LoCHs), respectively. The TrCHs are specified for data transport between the physical layer and L2 peer entities, whereas logical channels define the transfer of a specific type of information over the radio interface [2].
