MTN South Africa has completed a commercial network validation of a microwave spectrum-reuse capability. This new deployment enables the reuse of existing frequencies to support network expansion and accelerated 5G roll-out.

Why it matters

The solution helps address spectrum scarcity at hub sites where acquiring additional frequency bands is often difficult or prohibitively expensive for mobile operators. It effectively bypasses physical isolation limitations inherent in traditional microwave systems.

The system utilizes Huawei's Co-Channel Interference Cancellation (CCIC) solution to analyse interference in real time and generate compensation signals. This allows for frequency reuse by overcoming the physical isolation limits of legacy microwave setups.

The players

MTN South Africa

A leading telecommunications provider offering cellular network services across the country.

Huawei

A global technology company that provides the Co-Channel Interference Cancellation microwave solution.

The details

By deploying the CCIC technology, MTN South Africa can significantly increase capacity on existing microwave links without needing new spectrum licenses. The system suppresses co-channel interference, allowing signals to operate on shared frequencies within the network.

The Tech Race

This development represents a shift towards software-based capacity growth, replacing the traditional reliance on acquiring new, often scarce physical spectrum bands. It positions MTN to better compete in the infrastructure arms race by maximizing the utility of existing hardware.

Users can expect more stable connectivity and improved network speeds as the provider expands capacity in congested areas. This technology helps ensure that 5G services remain accessible even in locations where frequency bands are limited.

The takeaway

Operators are increasingly relying on advanced signal processing to stretch their existing assets further rather than solely depending on new spectrum auctions. Readers should expect continued improvements in network reliability as these efficiency-focused technologies become standard.
