Improving Transmission of Television Signals in Zimbabwe: Use of Microwave Links-Case of ZBC Harare

Abstract

With the explosive evolving world of technology, the paradox between volume dimensions and band scarcity has notably been rising. Competition for wireless bandwidth, particularly for 5G (fifth generation) has been a major problem for unguided media and networks. To satisfy transmissions for high-definition televisions (HDTVs) while providing ultra-high-definition videos (UHDVs) in 5G networks, anticipation has been on microwave link transmission due to its massive bandwidth. This is a maiden study which aims to improve the television signal transmissions of Zimbabwe Broadcasting Corporations (ZBC) by introducing microwave links to minimize system downtimes and overload in TV signaling currently experienced with radio links and fiber optic cables. The case-based study followed a mixed research approach with interviews and questionnaires done to 30 respondents in the production, IT, and programs department at different levels across ZBC Harare. The results were analyzed using SPSS and Microsoft Excel and the findings of the study showed that ZBC is using the fiber cable analogy television signals which are affected by such factors as high latency, fading, noise and size of antennas which lead to signal distortion and reduced signal strength. This research recommended the organization to turn a new technological launch into an event, keep the new technology on their radar and stakeholder awareness of benefits as the strategies to ensure the use of microwave link.
