A global integrated chemicals and energy company spanning 30 countries - converting coal into liquid fuels, pipeline gas and a broad spectrum of chemical feedstock - selected Aviat microwave radio for its refreshed communications network.

The plant needed a solution for connecting their TETRA sites that provides mission critical communication and plays an integral part of the safe and efficient functioning of the plant to ensure the smooth operation of a world class organisation.

SGT Solutions, in partnership with Aviat Networks (SA) (and local distributor), fulfilled the requirement with an industry-leading point-to-point microwave solution for the plant.

The preferred solution was the Aviat WTM 4000 all outdoor radios, considered to be the industry-leading radio with the highest capacity in a single transceiver, and exceptional price and performance.

The adaptive dual carrier (A2C+) feature enables two channels over a single transceiver, leading to twice the capacity compared to single header radios, or half the transceiver hardware as compared to dual-header radios. This means, less cost and power consumption per bit with more capacity.

Other features include 112MHz channels, 4096QAM, header compression and a built-in spectrum analyser with which you have the power to detect interference, determine alternative channel options, elimination of the source with the regulator and deliver exceptional service to your customers. Aviat Networks has also introduced the multi-band radio combining 80GHz with 11/13/15/18/23GHz bands in a single compact device which can make your network ready to deliver 5G services with high capacity and reliability.

This network consists of 22 point-to-point links connecting 19 TETRA sites. This includes nine sites located in the close proximity of the production plant and 10 sites located outside the plant. The furthest site is located 35km from the technical operating centre.

The network of 22 links was designed with a mix of 18GHz and 7GHz radios. This includes four high-capacity links with the transmission capacity of 500Mbps and 18 links with the transmission capacity of 230Mbps.

All links on this network can be upgraded to double the transmission capacity with licence and software upgrades only. The WTM 4000 features, including QinQ, which allows frames from multiple services to be tunnelled between the TETRA sites using service VLANs, QOS to guarantee high-priority traffic takes precedence over the lower priority traffic and Adaptive Coding & Modulation (ACM) which uses a rate adaptation algorithm that adapts the modulation and coding scheme according to the quality of the radio channel.

These features together with design of the network in a ring configuration for redundancy guarantees robustness and stability of the network. The Aviat radios also offer mean time before failure (MTBF) reliability figures approaching a 100 years, which ensures the ease of support on networks deployed with these radios.

“SGT Solutions was able to seamlessly solution a backhaul network that provided the highest value realisation for our customer with no QoS compromise,” notes Suraj Ramlall, GM, SGT Solutions.

The Aviat WTM 4000 radios deployed on the plant are managed by ProVision Plus which is Aviat’s next-generation management and application platform, designed from the ground up to minimise the total cost of ownership and maximise the intelligence and flexibility of modern complex wireless transport networks. ProVision Plus is an easy to use web-based system accessed via modern web browsers such as Google Chrome and Microsoft Edge.
