Reliable and affordable telecommunications services have never been more vital to our national economic and social resilience.

That is why, across Africa and throughout the globe, national leaders and policymakers are prioritising the preservation of satellite broadband access – and why South Africa needs to keep pace with the rest of the world on this critical issue.

The technical details are relatively simple: the most widely useful and applicable satellite services are provided using the Ka-band, also known more widely as the 28GHz band.

What kind of useful services? They include:

Reducing “digital deserts” by bringing broadband Internet connectivity for unserved and underserved communities.
Ensuring near-ubiquitous access and vastly improved quality across the most densely populated urban areas. Among other benefits, the 28GHz band lets satellite operators deliver the capability to pinpoint configurations of access when demand is at its peak.
Reducing constraints on access by delivering a wider range of price choices and service options. The 28GHz band also lets satellite companies pass along its lower costs of transferring to consumers.
Powering economic development through new connectivity services for expanding market segments, such as land, air and maritime transport routes.

On top of all that, equipment costs for satellite systems using the 28GHz band are also more affordable, smaller in size and widely available. All those benefits are at risk, because some “terrestrial” telecoms equipment manufacturers and providers are trying to take the 28GHz band for themselves. Do they need to? Absolutely not. Terrestrial operators have more than enough other spectrum to accommodate 5G mobile service. Additionally, the 28GHz band is not being used globally for 5G.

Governments, Apple and consumers in other parts of the world are not prioritising 5G networks using 28GHz. Those that have in the past, including the US, are now shifting their focus due to the high costs of new antennas and handsets: terrestrial telecoms companies would need thousands or millions of new towers, making 5G networks using the 28GHz band unrealistic, while lower-frequency bands require far fewer towers.

The reality is that terrestrial telecoms providers can easily be accommodated in the 26GHz band as it offers 3.25GHz of spectrum. There are also mid-bands and low bands becoming available for 5G. So, what are these terrestrial telecoms claims to the 28GHz band? Not much more than an attempt to eliminate competing companies — satellite broadband companies — that have a proven history (and a future) of offering tangible benefits in accessibility, service, cost and socioeconomic development.

The rest of the world has taken the position that the 28GHz band should be preserved for satellite broadband access. Precisely because 5G has multiple substitute bands and large amounts of spectrum available already, countries have prioritised the entire 28GHz band without fragmenting it or splitting it with 5G services. Most of Africa, the entire European Union, Latin American nations, Australia, China and the United Arab Emirates have now protected the 28GHz band for satellite services. The US has recently moved to focus on low bands and mid-bands for 5G because of the better propagation characteristics in those bands.

There are also economic and even national security downsides to not preserving the 28GHz band for satellite broadband access, which would lead to costly and complicated arrangements, especially given that 5G systems are incompatible with satellite services in the 28GHz band and that the 28GHz band is ubiquitously used around the globe by satellite operators, which has implications for commerce, travel, accurate weather forecasting and national security.

The solution is as simple as the benefits are clear – South Africa should make the right decision today, follow the African and global trends, and preserve the 28GHz band for satellite services to get the benefits of satellite in the 28GHz band, while retaining the value of 5G in other globally harmonised bands.
