EXECUTIVE SUMMARY(PDF)

In the early days of WiFi and 3G, operators and vendors invested significant effort in trying to understand how the two technologies would interact: whether 3G would wipe out WiFi, or vice versa, or whether we would see a world with a harmonious mix of both technologies.

At the advent of 5G we find people having the same discussion. Will 5G make WiFi redundant? If not, how will the two technologies fit together? And what should this mean for any individual company's strategy?

Whether or not WiFi has a future is not in doubt. The evidence is overwhelming that WiFi will be a major means of delivering wireless connectivity in coming years, all around the world. Organizations of many types will continue to invest in large-scale WiFi networks, and mobile network operators will not be the only types of firm deploying WiFi.

Delivering 5G service performance objectives will likely require a mix of licensed, shared and unlicensed spectrum approaches, but this does not mean that WiFi will necessarily be become a chargeable extension of mobile services. Customer expectations in most markets will simply not allow that. WiFi is seen as free at the point of access in many scenarios; and even where it isn't, building owners won't want to share control or money with the mobile operators.

Mobile operators should nonetheless pursue strategies that integrate their LTE and 5G networks with WiFi infrastructures as far as they can. Rather than planning a LTE/5G strategy to replace WiFi, they should take advantage of the cost, reach and customer satisfaction qualities it can deliver. They should be realistic about their very poor prospects of getting people to pay for better mobile in the home or office – particularly when they have had WiFi for "free."

WiFi Prospects in a 5G World explores recent patterns in WiFi deployment and improvements to the technology. It reviews the likely impact of business models, installed base of legacy infrastructure and vested interests – all of which will influence the evolution of the market – exploring how WiFi and 5G are likely to fit together.

While WiFi technology has been steadily improving, so its adoption within global markets has continued to rise. In fact, there is no immediate sense that investors are shying away from WiFi in anticipation of the arrival of 5G networks. On the contrary, there are several reasons why WiFi will be around for a long time.

WiFi Prospects in a 5G World is published in PDF format.

Google's Investment in India's Public WiFi Infrastructure: A Waste of Time & Money?

Heavy Lifting Analyst Notes

Back when WiFi and 3G were young, operators and vendors were trying to figure out if and how wide local area network (WLAN) and cellular technologies would coexist. They were wondering whether WiFi would dominate, whether cellular networks would sweep all other wireless technologies before them and what either outcome would mean for their strategies. (I know this because I was sitting in a room with very many of them, running scenarios to think through the possibilities.)

What came to pass was a pretty harmonious mix.

Fast forward nearly 20 years. As operators collectively spend billions of dollars on deployment of Long Term Evolution Advanced (LTE-A) and soon 5G networks, some pundits have suggested that in the context of 5G, with all-you-can-eat mobile data packages, the days of WiFi might be numbered.

Google, however, does not seem convinced. As part of its "Next Billion Users" project, Google has been installing public WiFi hotspots at over 400 railway stations throughout India. Over 8 million users per month are already using the service, which gives 30 minutes of free Internet access, consuming 350 MB per session, with more than half of them active for more than one session in a day. Next Google plans to install additional hotspots in city locations around the country.

Is its effort a waste of capital? Mobile services are not going to compete with that any time soon. Google, of course, has an alternative revenue source -- advertising -- that clearly helps to justify its expenditure here. The same is also true of other independent WiFi providers, of which there are many, city and government investors with other business models in mind and of cable operators seeking to make their fixed broadband services more attractive.

Instead, perhaps it is would-be 5G cellular network operators who have got it all wrong? They are planning dense deployments of millions of 5G small and micro cells to deliver their next-generation services, including in homes and business where WiFi has traditionally been strong and in busy urban areas where WiFi hotspots are being installed.

Heavy Reading's latest report WiFi Prospects in a 5G World explores recent patterns in WiFi deployment and improvements to the technology. It reviews the likely impact of business models, installed base of legacy infrastructure and vested interests -- all of which will influence the evolution of the market – and considers how WiFi and 5G are likely to fit together in the coming years.
