Department of Science and Technology (DST) and Microsoft have recently signed memorandum of understanding (MoU) to ensure the foreign direct investment in research and development. The MoU is aimed encouraging existing information and communication technology (ICT) skills program to support knowledge-generating capacity. The DST and multinational private sector partners have a solid framework against which to quality-check projects in which they are engaged together. A student-to-government program could do much to engage unemployed graduates, give them the appropriate practical training and place them in internships to expand their skills. DST is leading the implementation of the National Information and Communication Technology Research, Development and Innovation strategy aimed at achieving an increase in advanced human resource capacity, and build robust innovation chains that results in the creation of high-tech ICT small enterprises.

Dr. Timothy Gibbon at the Department of Physics at the Nelson Mandela Metropolitan University (NMMU) in Port Elizabeth shares views on a project, GigaWam, undertaken by him during a three year post-doctoral stint in Denmark. GigaWam is a €6,9-million EU-funded project aimed at developing all technologies for a complete fiber to the home-network based on wavelength-division-multiplexed passive optical network (WDM-PON) technology. GigaWam offers 1 Gbps bi-directional access per user. Dr. Gibbon worked with six different companies, each one producing a different component for the network. He worked to produce a system specification for the entire network. Each company would then develop and provide their components to be incorporated into an experimental network that put together and tested in the lab at the Technical University of Denmark. Dr. Gibbon also worked on other projects that include the short range ultra wideband (UWB) wireless technology for home and personal network applications such as connecting a DVD player to a TV.

Telkom Mobile has introduced its network that uses billboards to house their base stations and antennas. There are 22,000 billboards in South Africa and Telkom Mobile has signed a long term agreement with the owners to collocate their base stations on these sites. Base stations at billboard sites reduce the visual impact associated with mobile radio networks. The total antenna solution fits over the billboard without any invasive measures to secure it. The antennas are equipped with remote tilt functionality to allow vertical adjustment of the radiated pattern in the field. The unique facility allows the signals to be beamed to the target area, increasing efficiency and focusing signals where it benefits users of the network most. The radio network is built on a flexible technology platform that allows it to switch between multiple technologies such as GSM, UMTS and in the near future to LTE, operating on the network's currently operating frequency bands.

The mobile radio industry or public mobile radio (PMR) is rapidly changing from FM to digital due to increasing demands from the private and public sectors. These sectors seek more services, greater flexibility, and security and need to make more channels available within the limited frequency allocations for mobile services. There are two standards in the existing markets for transition of PMR from FM to digital, such as a system originating from Icom Japan, called IDAS and terrestrial trunked radio (TETRA), a digital trunked mobile radio standard developed by the European Telecommunications Standards Institute (ETSI). The objective of the TETRA standard is to meet the needs of traditional professional mobile radio (PMR) user organizations. it specifies the network interfaces, along with the services and facilities in detail to enable independent manufacturers to develop infrastructure and radio terminal products for full interoperatability with each other.

Several companies are outsourcing their data centers or collocating in a vendor-neutral data center ensuring the reduced costs for companies. The increased demand for mobility, with more and more employees bringing their laptops and tablet PC into the workplace leads to a challenge for connectivity and more comprehensive security. Lex van Wyk, MD of Teraco believes that in multi-tenant data centers the energy resource requirements are reduced through the economies of scale gained from centralized and shared services. Companies can host their own business critical data but with equipment located in a vendor-independent data center. Van Wyk believes that there are several issues that need to be addressed before collocating such as the company offer a good service level agreement and 5/9 availability and there should be an open access with multi-vendor connectivity.
