As consumer needs and requirements evolve and as interest in emerging technologies grows, what are the telcos doing to provide the backbone?
South Africans are spending more time online than ever before. In-fact, over the last decade, internet traffic in South Africa has grown by around 500 000%. This leap can largely be attributed to changes in the type of content users consume, notably the significant increase in high-definition video streaming. And with the rise in future technologies promising to transform everything from entertainment and training to workplaces and healthcare by making it possible for connect in new and different ways, the amount of capacity that network operators need to provide is only set to climb.
But this doesn't necessarily mean that telcos need to rush out and build super-fast, advanced networks right away, says Spiwe Chireka, a telecoms expert. "We must remember that relevant supply drives demand", she says. According to Chireka, the market in Africa is always driven by the three as: availability, accessibility and affordability. All three must co-exist in order for anything really take off and, at present, when it comes to many of the sexy emerging technologies that are making news headlines, they don't.
Mark Walker, associate VP for Sub-Saharan Africa at the IDC, shares this sentiment. Using the metaverse as an example of the future of the internet he says that this immersive world and its related technologies are still very incipient. He cites the gaming segment as one area where we can already see real use cases for highly immersive, virtual environments. "Business will only invest in something if it is going to help them make money. So, at the end of the day, gaming may be showcasing what can be done in the metaverse but, currently, the use cases are still far too specific. "But that doesn't mean that local telcos aren't making moves to ensure that their networks are ready for the technologies of the future. Schalk Visser, CTO at Cell C, says it's focusing on partnership, both with enablers and content. Modern telcos are working to better understand their customers' core requirements so that they can tailor their offerings to address these needs. "By adding to the ecosystem and providing the services that our customers want and need, we can open up a lifetime of value for our existing, as well as our prospective customers," he says. In this way, new and emerging technologies provide an incredible opportunity for telcos to tap into new markets and play further up the digital value chain, he further states.
"As telcos start investigating what they need to do move away from being a traditional communication provider and toward becoming a technology provider, they are no longer just offering the plumbing, they are also adding value and expanding the use of their plumbing," says Walker. "In this way, they are moving from being a communication or connectivity provider to becoming a full digital services provider."
The role of 5G in our digital future
While current 5G networks serve as a solid foundation for the innovations of the future, the high-performance networks needed to enable this will be powered by 5G Advanced – which is expected to strengthen 5G by improving speed coverage, mobility and power efficiency – and 6G. Offering significantly higher bandwidth, super-fast data speeds and extremely low latencies, the emergence of 5G Advanced and 6G will enhance use cases for more connectivity. "Current 5G implementations do not give consumers any revolutionary experiences other than perhaps a slight improvement. This is because the applications used by consumers today don't really demand too much from 5G networks," says Octavio Garcia, a senior analyst at Forrester Research. Garcia's colleagues agree. "By the time we have any type of critical mass of untethered VR headsets or the metaverse, 5G will likely be considered to be a slow network," says Forrester Research's Julie Ask, a VP and principal analyst. When discussing infrastructure development, Walker says that as we move to higher frequencies, the physical constraints emerge. The higher the frequency (from 5G to 6G), the shorter the wavelength, which equates to less transmission power and means that we are going to need a lot more base stations to cover the same area. And it's not just about communication infrastructure, Walker adds, it's also about all the associated infrastructure needed to move huge amounts of data from one point to another very quickly. And let's not forget that something like satellite connectivity has the potential to change the game entirely. In the case of satellite, cost remains a major inhibitor, but as use increases, costs will naturally come down. Walker points out that internet systems such as Starlink, the world's first and largest satellite constellation using a low Earth orbit to deliver broadband internet, almost eliminates the need for telcos entirely because satellites don't have to link up with base stations on the ground.
And given the South Africa's energy woes, local mobile operators are increasingly looking to Open RAN to build their mobile networks. Not only does Open RAN reduce power consumption and emissions, it also promotes vendor diversity and creates opportunities for smaller suppliers to enter the game. So, what should telcos be doing to prepare for the future of their industry? Walker advises that they wait. This doesn’t mean they should sit back and do nothing, but he suggests that they make any big bold moves just yet. "Take strong observatory approach. Get your periscope up there and be on the lookout for what's happening." He also suggests that local telcos get close to the players of the market that are making big strides in the network innovation space so that you can keep an eye on what's going on. "And, perhaps more importantly, watch what your clients are doing so that you can identify potential avenues to apply modern solutions and technologies to replace existing processes and improve business outcomes."
