Wi-Fi calling in SA to go mainstream


Wi-Fi calling will soon become a natural part of South African networks once they get over their fear of the technology, says a local provider.

“I think with time they will. What I’ve noticed locally is that as South Africans we are very cautious of change and undertake smaller roll-outs to test technology solutions to see if they work before we make huge invests in them,” said Michael Fletcher, sales director sub-Saharan Africa at Ruckus Wireless.

Wi-Fi has long been seen as a high-speed alternative to mobile data networks, but despite widespread adoption on small scales, the technology faces resistance from mobile network operators.

Wi-Fi is regarded as ideal for only short range communication and the spectrum is unlicensed — a key concern for large network operators.

Despite this, new technologies are causing operators to take a second look at Wi-Fi technology, especially in high traffic areas where it is difficult for companies to cope.

“Wi-Fi has proven to be a complementary solution for mobile operators in their effort to improve their service delivery to their customers and Wi-Fi calling is the next step,” said Fletcher.

Ruckus has demonstrated a number of key technologies that makes Wi-Fi viable, especially as regulatory delays continue to stymie efforts to deliver true 4G and even 5G spectrum.

Some technologies include secure networks, carrier grade traffic management and long range Wi-Fi switches.

In South Africa, AlwaysOn has launched its Wi-Fi calling service which operates along the lines of popular services such as Skype and WhatsApp calling.

In the US, Sprint and T-Mobile provide Wi-Fi calling where the device can automatically switch to a Wi-Fi network if the mobile network in unavailable.

Wi-Fi could make an impact in rural areas traditionally under-served by mobile operators.

“Wi-Fi installations could mean the difference between no ICT access of any kind and an affordable service as it can be used as a complementary medium to enhance the operators’ offering — allowing them to get cost effective access to consumers in these areas,” Fletcher said.

In the City of Tshwane, Wi-Fi is seen as a critical element of the government’s policy of driving universal Internet access by 2020.

The Western Cape government is intent on spending R1,3bn as part of a broadband initiative for the province, in line with the South Africa Connect broadband policy.

“Pervasive and affordable broadband is likely to stimulate innovation in broadband applications and services. This needs to be accompanied by investments in the development of critical mass, in ICT R&D capabilities, in innovation support measures and in advanced human capital development,” says the policy document.

Project Isizwe has launched a pilot programme of Wi-Fi Internet access in the rural Eastern Cape at the Ingwe TVET College Mount Frere and Lusikisiki campuses.

“Everyone says ‘It’s easy in Tshwane, but you can’t do it in a rural area’, but here we are,” Alan Knott-Craig, the brains behind Project Isizwe, said recently.

But Wi-Fi access through calling has serious implications for mobile networks — especially if there was widespread adoption, warned Fletcher.

“The technology used for Wi-Fi calling will drive greater amounts of smartphone traffic onto Wi-Fi networks and this could fundamentally change the mobile network operator business model.”

He added that consumer patterns have already dictated that Wi-Fi is a national connectivity standard.

“The reality is many consumers have become used to the idea of connecting their mobile devices to their home networks or other wireless hotspots to save on costs. It would therefore be a natural extension to use this connectivity for things such as voice calls and text messages.”  — Fin24


  1. Do the right thing on

    I use wifi calling as it is cheaper than call tariffs , so in a nutshell if the vodacom,cell c and MTN etc cannot provide more competitive rates why use them.The consumer has in any event been ripped off over the years by these operators who sold and packaged data as voice calls and sms.I for one have saved hundred already from using wifi and data calling using whatsapp.This is what service providers forget , the market always normalises , now the SP’s are under pressure to cut staff and costs as the previous revenue streams(voice , sms etc) are no longer profitable , in the end they will become suppliers of data or even be taken over by whatsapp etc.

  2. It’s worth noting that all WiFi calling is not the same. The key difference is whether the call is simply a VoIP call from device to device over the WiFi network/Internet, or whether you can place a call to a fixed or mobile network. The latter means there has to be some kind of settlement with the fixed or mobile operator — interconnect charges will apply.

    Skype (free) and WhatsApp calling are simply peer-to-peer VoIP, but don’t allow breakout.

    Skype (paid) AlwaysOn’s WiFi calling can call fixed or mobile if you cough up some money. Not a lot… better value than existing fixed or mobile.
