Projects

Radio Telecommunication Services (Pty) Ltd assisted The Independent Communication Authority of South Africa (ICASA) with the review of the National Radio Frequency Plan 2018 which was based on input from WRC-15 to produce a new NRFP based on WRC-19.

The scope of work entailed the following:

  • To update the National Radio Frequency Plan to reflect the Final Acts of WRC-19.
  • To ensure the National Radio Frequency Plan is in harmonisation with the Southern African Development Countries (SADC) Frequency Allocation Plan.
  • To review the existing National Radio Frequency Plan to ensure that the spectrum allocations reflect the usage of the radio frequency spectrum up until the planned date of the next WRC in the short term.
  • To ensure that the International footnotes included in the WRC-19 Final Acts are properly reflected in the National Radio Frequency Plan.
  • To ensure that the National footnotes to the National Radio Frequency Plan adequately explain the use of the radio frequency spectrum band where this is required.
  • To ensure that the National Radio Frequency Plan, including the National footnotes, reflect  any frequency migration that is necessary in the short term and as described in the Frequency Migration Plan (FMP).

The updated NRFP-21 included thus frequency band changes, new ITU resolutions,  ITU-R Recommendations  and footnote changes that were accepted at the last WRC. The latest recommendations and resolutions were added where applicable to a specific frequency band.

Radio Telecommunication Services (Pty) Ltd has developed and launched a digital version of the NRFP (National Radio Frequency Plan) – 2021, as gazetted on 25 March 2022.

The general idea of the project is to develop a user-friendly web interface hosted on the ICASA and RTS/LSofSA websites which can be used to view a digital version of the NRFP-2021. The interface allows any user to run various types of filters to be able to view required extractions from the NRFP-2021.

The Independent Communication Authority of South Africa (ICASA) appointed RTS to develop and implement the migration plan, which includes the development of radio frequency spectrum assignment plans and implementation of the IMT Roadmap services.

The Authority’s primary objectives are to ensure spectrum efficiency, universal availability of broadband services as well as a vibrant and competitive telecommunications industry and promote investments.

Radio Telecommunication Services (Pty) LTD was appointed by South African Radio Astronomy Observatory (SARAO) for the supply, implementation, and maintenance of a professional Automated Spectrum Management System with a web interface.

The SPECTRA system and with all its functionalities were offered and successfully implemented at SARAO.

The Spectrum Management System offered to SARAO is a unique solution, ideally suited for the SKA’s intention to further enhance its spectrum management capability. The system implement in South Africa can be replicated and linked up to the system in Australia to manage the spectrum on the Australian portion of the array. The Australian regulator ACMA also makes use of our SPECTRA spectrum management system for its spectrum management requirements.

Radio Telecommunication Services (Pty) Ltd was contracted by the City Of Umhlathuze to perform a survey of a 132 kv Overhead Line that runs across the City. The complete survey consisted of 27 Pylon inspections by means of a Remote Piloted Aircraft. 

The inspection was done by flying a highly specialized drone near the pylons and over the line. The drone was equipped with a High Definition RGB camera, with both a 15mm and 45mm lens to ensure that the best quality images were delivered to the client. A thermal camera was also attached to the drone and all inspections were completed with both payloads.

The scope of work entailed inspection of the Pylons and reporting on the condition of the following:

  • Visual and Thermal Images
  • Condition of Steelwork
  • Condition of Metalwork (Coating)
  • Condition of Earthing
  • Condition of Concrete Structures
  • Condition of Vibration Dampers
  • Condition of Tower Labels
  • Condition of Arching Horns
  • Condition of Foundation
  • Condition of Stays
  • Condition of Phase Insulators
  • Condition of Anti-Perching Devices
  • Condition of the Conductors
  • Condition of Corona Rings
  • Condition of Compression Joints

Sentech a state-owned company and the largest broadcasting signal distributor in South Africa appointed RTS for the supply, delivery, installation, and support of a 25KW medium wave transmitter at the Klipheuwel site in Cape Town for Cape Talk service and Cape Pulpit.

Sentech is a licensed Electronic Communications Network Service provider in South Africa. It currently operates many telecommunication networks for Satellite, Television, Radio, Internet and more. As such, Sentech is a global enabler of broadcasting and digital content delivery. The replacement of this transmitters was critical to ensure that Sentech meets the SLA with customers, avoid possible revenue loss due to long delays and protecting Sentech reputation.

 RTS offered a Nautel’s NX25 solid state medium wave broadcast transmitter for both radio stations.
