This study was conducted to look into state-owned ICT institutions. The emphasis was on devising a strategic management framework that would be robust and agile, thereby enabling government companies within the ICT sector to rapidly respond to changes in the market and to also enable them to forecast and plan for the future in respect of technology. The main objective of the study was to derive an ICT strategic management framework for the rapid technological evolution of state-owned companies. Further, the study aimed to provide a critical exposition of the factors that affect company ICT strategies; assess the impact of technological changes on company ICT strategies; and propose guidelines on keeping companies‘ ICT strategies responsive to rapid technological changes. Through the literature review as well as an empirical study, common variables and factors that affect a company‘s ICT strategy and its response to technology changes were explored and guidelines were compiled into a framework that will assist SOEs (state-owned enterprises). Through a literature study of available material on the world‘s telecommunication trends and developments in developed nations, some key observations were recorded such as the concept of convergence, which in the main is driven by consumers‘ need for mobility and flexibility, as well as applications with high capacity demands on the one hand and the need for companies and telecommunications operators to be more efficient on the other. Convergence delivers this benefit of efficiency within the market and stimulates competition. Innovation and creativity continue to be the driving force behind the technological evolutions in the ICT sector. The study also considered how both the PEST model and Porter‘s five forces affect these companies. Issues such as the legislative and policy framework of the ICT industry in South Africa were looked at, with emphasis on how they affect ICT parastatals. The study ended with key recommendations and guidelines summed up into a comprehensive framework. / MBA, North-West University, Potchefstroom Campus, 2015

International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / The use of low windload FLAPS™ antennas in telemetry tracking systems yields sizable savings in system cost due to the reduced requirements imposed on the pedestal assembly and on the underlying support structure. Traditionally the use of these antennas has been limited to applications in which frequency bandwidths did not exceed 10-13%. This paper describes a variation of the FLAPS™ technology which allows operation over bandwidths in excess of 35% and makes it usable in broadband systems. Two new applications are feasible: one for a ground based telemetry system operating in the 1435-1850 or 1750-2400 MHz band and one for a shipboard satellite communication system operating in the 4000-6000 MHz band.

International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The requirement for a lightweight, quick deployment C-Band satellite communication antenna system for Aegis Class Destroyers has been addressed and this paper describes a novel solution currently being implemented. The new antenna system takes advantage of the low windload properties of the FLAPS™ (Flat Parabolic Surface) reflector and features a broadband FLAPS™ reflector mounted on a lightweight, high performance X-Y positioner. The system is designed in a modular fashion and operates in a shipboard environment without the protection of a radome. The system is stabilized to counteract the ship's motion, operates without counterweights, weighs less than 250 kg and provide communication links in the 3900 to 4100 MHz and 6000 to 6200 MHz frequency bands.

ITC/USA 2015 Conference Proceedings / The Fifty-First Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2015 / Bally's Hotel & Convention Center, Las Vegas, NV / Power line communications (PLC)-based transceivers provide an alternative to establishing dedicated aircraft Ethernet networks. Adding new aircraft functionality or installing special purpose instrumentation often requires significant engineering and aircraft down time to complete. PLC-based networks can reduce project cost and schedule by enabling localized aircraft modifications and leveraging existing aircraft wiring for the Ethernet medium. PLC standards continue to evolve and achieve greater throughput rates and noise mitigation. Ethernet communications have been tested over AC and DC power busses, data busses, and discrete wiring. PLC networks have been successfully demonstrated in avionics test beds and aircraft (including live video transfers) without causing interference to the basic systems or the underlying wiring functionality. PLC transceivers provide a cost effective solution to the adding Ethernet capabilities or Ethernet-based subsystems to existing aircraft.
