Elements and Performance Criteria

1. Plan and prepare for design of cellular mobile networks
   • Analyse requirements of the mobile network
   • Examine technical characteristics of the GPRS systems
   • Develop network architecture for a GPRS network, in addition to the circuit-switched domain of 2G (Generation)
   • Review 3G structure and identify network requirements to provide a wide variety of services ranging from voice and paging services to interactive multimedia, including teleconferencing and internet access
   • Examine technical characteristics, data rates, operating frequencies and multiplexing schemes of the 3G system
   • Establish positioning and types of antennas, terminals, processors, required protocols and architecture, based on technical specifications and requirements
2. Design a GPRS (2.5G) cellular network
   • Investigate how 2.5G GPRS overlays the GSM network to transmit and receive transmission control protocol (TCP) and/or internet protocol (IP) based data to and from GPRS mobile devices
3. Design a 3G cellular network
   • Develop network architecture for a 3G network and explain functions of the network elements
   • Integrate a 3G network with a wireless local area network (WLAN)
4. Research and evaluate design features of proposed 4G cellular network
   • Investigate how a fully IP-based 4G system will provide an end-to-end IP integrated solution for voice, data and streamed multimedia to end-users roaming anytime and anywhere
   • Investigate access schemes of a 4G network
   • Investigate the implication for Internet Protocol version 6 (IPv6) in relation to 4G support of a greater number of IP-based wireless devices with applications for improved multicast, security and route minimisation capabilities
   • Investigate use of advanced antenna systems to enable 4G with high rate, high reliability and long range communications
5. Produce reports for architectural design for cellular networks
   • Present a report on the impact of competing technologies on each other and get consensus on concepts
   • Investigate potential interoperability and global roaming issues that may be faced by GSM, 2.5G, 3G and 4G cellular technologies
