The increasing appetite for Carrier Wi-Fi solutions will result in revenues growing to nearly $8 billion (€6.4 billion) by 2019. The pieces of the carrier Wi-Fi puzzle are falling into place as the standardization process speeds up with the recent updates on Hotspot 2.0 and commercial Next Generation Hotspot deployments counting more than 12 networks worldwide--implementing Cisco and Ruckus equipment. Other main market players include Alcatel-Lucent, Nokia, and Ericsson. Asia-Pacific is the top region in [terms of the] number of installed Wi-Fi hotspots while Europe and North America continue to grow their networks through the use of community hotspots. MSOs like BT, Liberty Global, and Comcast are advertising millions of public hotspots, thanks to switching on the dual-access feature in their massive home gateway deployments. Mobile operators have started turning to Wi-Fi for voice support in addition to data which further increases the value of public hotspots. Examples include AT&T, Verizon, T-Mobile, and EE which are either currently offering Wi-Fi calling services or planning to do so in 2015. Release
