Negotiating SA’s broadband bottleneck

While wholesale pricing has dropped dramatically and the end consumer continues to get more bandwidth more affordable, there is still work to be done in achieving a fully connected society by 2020.

The government and the regulator in South Africa are critical players in unlocking further growth through exploring a range of unified initiatives from private-public partnerships, rural development mandates to spectrum allocation and local loop unbundling.

“The journey of a byte from its global point of origin to the South African consumers’ screen is a long and complex one that involves several players along the way, starting from the upstream supplier, through the submarine cables, and then pushing through long-haul fibre networks linking cities and cellular towers to each other.

“Internet service providers (ISPs) collect the bandwidth from datacentres and then use their own or shared last mile infrastructure to get to consumers either over the air to their handsets or through the ground to houses and offices,” says Aidan Baigrie, head of business development at SEACOM.

“Whilst we have seen spectacular growth in submarine capacity over the last two years, this has not been the case downstream with the backhaul and last mile infrastructure players.

“As a result there is a disconnect between the ample supply of affordable international connectivity to the shores, and the supply of affordable bandwidth to both rural and city based end consumers inland,” Baigrie says.

Submarine connectivity accounts for around 90-95 percent of the distance a byte of information travels, yet is only a fraction of the total cost of a service to the consumer.

Backhaul and last mile connectivity on the other hand is scarce and as such is priced at a premium, traditionally providing healthy margins for operators and infrastructure providers who have these assets.

The upside to the higher margins being offered to terrestrial backhaul players is that this promotes competition. With the inevitable arrival of competitors, there will be increased supply of fibre, and as such further competitive pricing reductions ensuring the end user reaps the benefits.

This will ensure that busy routes will be priced more affordable in the next 12 months. However this story changes for those in less densely populated areas where the monetary return on investment for rural fibre initiatives is harder to achieve.

Here government needs to continue to facilitate and provide incentives for operators to invest in, enter into private-public partnerships or use vehicles such as state-owned enterprises (SOE) to get backhaul and last mile infrastructure built, Baigrie adds. Whilst this is being done by a handful of SOEs, the most effective means is to incentivise the private sector.

The final and arguably most crucial leg is the last mile. Last mile connectivity comes in two forms, either through a fixed line such as copper or fibre into homes and offices or over the air from mobile operator base stations to mobile devices. South Africa, being a mobile centric internet market is critically dependant on the latter.

“With the influx of affordable and open access ‘smart’ handsets and devices African’s have leapfrogged the fixed line era and substituted it with mobile connectivity. The result is a strong dependence on our mobile operators and their networks,” says Baigrie.

Mobile networks are dependent on available and allocated spectrum to deliver internet over the air and to utilise new technologies such as LTE or 4G.

Spectrum is a rare commodity and the government and regulator have key roles to actively optimise the country’s use of spectrum and allocate it fairly and effectively.

We are seeing positive private sector engagement here in supporting the crystallisation of the Regulator’s approach and this issue is being further addressed through initiatives such as the migration from analog, spectrum heavy, television signalling to a digital television service, freeing up bands for reallocation amongst operators.
