Comsol, the South African enterprise and wholesale network operator, is working with ZTE to deploy 5G-Advanced broadband connectivity in South Africa, according to a report by The Fast Mode.

The announcement puts two names on a familiar promise: faster mobile broadband built on 5G-Advanced, the 3GPP Release 18 evolution of 5G. What the announcement does not yet put on the table is equally telling. Neither subscriber targets, deployment timelines, spectrum bands, nor investment figures appear in the reported material.

What is actually on the record?

The core claim is straightforward. Comsol and ZTE are advancing 5G-Advanced broadband connectivity in the South African market. ZTE brings the vendor side of the equation — radio access equipment and the chipsets, antennas and software features that Release 18 enables, including uplink capacity gains and better performance at cell edges.

Comsol brings the operator side. The company operates a carrier-grade network used by enterprises, wholesale customers and ISPs across South Africa, and it has positioned itself around private 5G and fixed wireless services rather than consumer mass market.

Beyond those two facts, the reported announcement offers little that can be stress-tested.

What 5G-Advanced means in practice

5G-Advanced is the standards-track name for 3GPP Release 18 and onward. Compared with earlier 5G releases, it targets:

• Higher uplink throughput, relevant for enterprise video, surveillance and cloud workflows
• Improved spectral efficiency on existing spectrum holdings
• Lower latency for industrial and private network use cases
• Better support for RedCap devices and IoT at scale

For an operator like Comsol, whose business leans on enterprise connectivity, the uplink and efficiency gains matter more than the headline downlink peaks vendors tend to quote.

The South African context

Spectrum remains the structural constraint on any 5G story in South Africa. The country's long-delayed spectrum auction in March 2022 finally released high-band and mid-band licences to the major operators, and ICASA, the regulator, continues to weigh further assignments and licence conditions. Any 5G-Advanced rollout's real-world throughput will depend on which bands Comsol holds and how much bandwidth it can aggregate — details absent from the announcement.

ZTE's position also carries geopolitical weight. The vendor faces restrictions in the US and parts of Europe, and its footprint is concentrated in markets across Africa, Asia and the Middle East. For South African operators, ZTE typically offers pricing pressure against Ericsson, Nokia and Huawei, and that commercial dynamic may be as significant as the technology itself.

What the announcement leaves unsaid

A skeptic's read of the report produces a short but important list of gaps:

• No coverage targets — how many sites, cities or provinces the deployment touches
• No throughput figures — nothing a customer could measure against current 5G service
• No timeline — no dates for trials, commercial launch or nationwide availability
• No financial terms — whether this is a commercial contract or a joint showcase

Vendor-operator announcements of this kind frequently precede a proof-of-concept or a demo at an industry event rather than a revenue-bearing deployment. Until Comsol publishes sites, speeds or customers, the claim remains a statement of intent.

Why it still matters

South Africa has one of the more developed 5G footprints on the continent, with Vodacom, MTN, Telkom and Rain all running live 5G networks since 2020–2021. A move to 5G-Advanced by a wholesale-focused operator would mark one of the first such upgrades in the market, and it would give enterprise customers a reason to revisit service-level agreements.

The economics also bear watching. Fixed wireless access is a competitive alternative to fibre in a market where last-mile fibre deployment remains uneven; efficiency gains from Release 18 translate directly into more subscribers per site or more throughput per rand of capex.

For now, the pairing of Comsol and ZTE signals direction rather than delivery. Whether the two convert 5G-Advanced from a standards label into measurable South African broadband performance will depend on the deployment specifics — sites, spectrum and dates — that neither party has yet disclosed.
