Subject Overview: This subject provides the fundamentals of mobile and wireless network design. In particular it includes the following topics:
  • Introduction to wireless communications.
  • Frequency division, orthogonal frequency division, time division and code division multiple access. Frequency division duplexing and time division duplexing
  • The cellular concept, frequency reuse, channel allocation schemes, handoff, call control, interference, C/I analysis, interference limited capacity, sectorisation, system capacity based on call blocking.
  • Teletraffic models for cellular mobile networks, Erlang loss function (Erlang B), Erlang delay (Erlang C), M/M/m, M/M/m/n, M/G/1 Processor Sharing queue and their application to dimensioning cellular communications networks for voice and data, system capacity, demand modelling and performance, Grade of Service and Quality of Service
  • Propagation, free space propagation, basic propagation mechanisms, two ray model, empirical path loss models (Hata, Cost231-Hata, Erceg), log-normal shadow fading, small-scale multipath propagation and Rayleigh fading:.
  • SNR, sensitivity and link budget calculations, micro and macro diversity to combat fading, calculation of radio coverage for cellular networks: multiple access techniques for cellular communications.
  • CDMA system principals & spread spectrum for 3G wireless systems
  • Cellular broadband wireless systems (3G+ and 4G).
Objectives:

On completion of this subject, students should have developed the skills and knowledge required to understand the fundamentals of the design and evaluation of mobile and wireless networks and to be able to solve technical problems in the following areas:

• Analysis and evaluation of re-use planning via the calculation of key performance indicator such as CIR
• Application and evaluation of propagation models to wireless networks.
• Teletraffic modelling and performance analysis for wireless networks
• Dimensioning of wireless networks
• Modelling and design of CDMA wireless systems
• Performance evaluation of wireless broadband networks
• Design and evaluation of coverage for wireless networks based on a link budget
• Large and small scale fading mitigation using space diversity techniques

The student should be able to perform a basic design of a wireless system for both coverage and capacity for given performance targets. They should also be able to evaluate the coverage, capacity and or performance of a wireless system.

Assessment: • Formally supervised written examination – 3 hours 70% (end of semester). This final exam is a hurdle. To pass the subject students must pass the final examination
• A Project equivalent to 3000 words 30%.
