The report, compiled by Maravedis on behalf of the WBA, comes at a significant time for the wireless ecosystem. There is a growing consensus that the success of 5G, unlike previous generations of standards, will rely on the convergence of multiple Radio Access Technologies (RATs) in unlicensed, shared and licensed spectrum, with Wi-Fi playing a central role. Developments in the latest Wi-Fi standards, including 802.11ax, will improve Wi-Fi performance and capabilities to support 5G use cases – including high density networks, extreme Mobile Broadband (eMBB) and aggregation of multiple frequencies, amongst others.
“Wireless use cases are expanding rapidly, enabled by new technologies and spectrum in the unlicensed and shared bands”, said Adlane Fellah, Senior Analyst, Maravedis. “These innovations are laying the foundations for the 5G era, in which Wi-Fi will play a central role.”
As industry attention moves toward monetising Wi-Fi, the study also highlights the drivers of additional traffic over the network, as well as use cases with initial revenue potential in different verticals. In this year’s survey, the services most important to monetisation strategies for 2018 according to respondents included location based services (37.5 per cent), roaming (33 per cent) and marketing analytics (almost 33 per cent). The three Wi-Fi use cases tipped to drive near term revenue potential include: extending internet access and media to a full smart home, richer and more efficient enterprise services driven by cloud managed networks and security, and expansion of the Wi-Fi roaming model.
The report also highlights the power of Wi-Fi, along with Low Power Wide Area Network (LPWAN) technologies, to provide a rapid and cost effective deployment of various Internet of Things (IoT) applications, including the deployment of smart cities. But interoperability between different technologies, independent certification of devices and equipment and collaboration between different city stakeholders were identified as areas that connected city ecosystems must urgently address. The WBA’s Connected City Advisory Board produced the second version of its Blueprint in November 2017, which intends to help cities develop their plans to become smart and emphasises the need to bring together the complex value chain of city stakeholders.
Also uncovered in the report is the rising adoption of the WBA’s Next Generation Hotspot (NGH) to support seamless authentication and multi-RAT access. The survey found that NGH had crossed the chasm with 23 per cent of respondents confirming its implementation, and 30 per cent planning to by the end of the year,
“As Wi-Fi continues to evolve, enabled by new technologies, it has the ability to support new connected services and use cases in the 5G era across all segments including, Carriers & Service Providers, Connected Cities and Enterprise & Hospitality ecosystems”, said Shrikant Shenwai, CEO, Wireless Broadband Alliance.
“This report shows that confidence in Wi-Fi is at its highest level ever, as the industry starts to recognise the central role the technology will play in next-generation wireless networks. Further extended by 802.11ax, Wi-Fi will remain incredibly important to support a range of use cases and industries, but ensuring interoperability with other technologies will be the key.”
