Requisites for this module
MSC H64112 5G and Emerging Communication Systems
This course provides an introduction to the architecture and services of modern telecommunication networks. A general introduction illustrates the major features of a network, how they interact and introduce the concept of an intelligent network. Switching is an essential requirement and the ideas behind circuit, packet and cell switching are presented.
The basics of the TCP/IP protocol suite are described. Optical transmission and networking, key features for future networks, are discussed. To present the main concepts involved in current and future telecommunication and information networks, the concepts presented will be supported by the other core courses.
The aim of this module is to introduce the architecture and services of modern telecommunication networks illustrating the major features of a network, how they interact, and the concept of an intelligent network.
On completion of the course, the student is expected to:
1. Explain the architecture and technology involved in a telecommunication network
2. Describe the basic concepts of multi-user communications
3. Compare in detail the features of circuit and packet switched networks
4. Examine the concept of optical networking in terms of transmission, switching and architecture
5. Describe and understand the basic features of the TCP/IP protocol suite
6 Describe the principles of network analysis and solve simple problems using Markov models
Introduction to architecture and technology, Network structures, analogue and digital technology, plesiochronous and synchronous transmission, the core network, circuit, packet and cell transmission & switching, the access and mobile network networks.
Multi-user communications and OSI seven-layer model:
Introduction to multi-user communications. Basic concepts: multiple access, time sharing. Resource sharing: circuit switching, packet techniques, evolution to integrated service digital networks. Diverse response to excess demand; blocking, delay, degradation, adaptation. ISO 7-layer model for OSI: layering concepts; protocols and services; functions of each layer; applicability to communication network architectures.
Introduction to circuit switching for telephony. Basic requirements: connection and control. Hierarchical network organisation. Common control link switching systems, blocking probability calculation via link independence approximation. Digital circuit switching: time slot interchangers and TDM space switches; TST and STS arrays.
Packet switched networks, ARQ protocols, congestion and flow control. WAN: ALOHA and slotted ALOHA. LAN: CSMA/CD, token ring, Cambridge ring. Multi-service networks: MAN; DQDB, FDDI, gateways and bridges.
Optical Networks (Transmission, Switching & Architectures):
Network transmission techniques. WDM: principles, limitations on wavelength numbers. Advanced technology: multiplexers, filters, optical amplifiers. Application of advanced technology to WDM systems. Optical time division multiplexing. Subcarrier multiplexing. Optical switching: relational and logical switching, switching bandwidth and power, spatial bandwidth, optical switch elements, space, time and wavelength switching. Network architecture: broadcast and select, wavelength routing, bandwidth limits.
An introduction to TCP/IP
History, function, implementations
Probability, conditional probability, random variables, probability density functions, cumulative distribution functions, mean and variance of a random variable, statistical distributions.
Network performance analysis
Markov chains and their properties. Erlang and Engset distributions. M/M/1 and related queues. Blocking, delay and packet loss. Traffic problems using Markov model.
The above list is indicative of the essential reading for the course.
The library makes provision for all reading list items, with digital provision where possible, and these resources are shared between students.

be necessary to make changes, for example to programmes, modules, facilities or fees. Examples of such reasons might include a change of law or regulatory requirements,
industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to modules may for example consist
of variations to the content and method of delivery or assessment of modules and other services, to discontinue modules and other services and to merge or combine modules.
The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications and module directory.
