Trustive researched more than 100 Hotspot operators with more than 44,000 Hotspots in Europe, Asia and the US. 80% of the operators have at least one roaming agreement with a hotspot aggregator. Almost 20% of the current revenue is coming from roaming. The three most used hotspot aggregators were Trustive (45%), iPass (43%) and Boingo (40%). Those same three aggregators also provided the most supported smart clients: iPass (45%) Boingo (33%) and Trustive (31%). 36% of Hotspot operators believe Voice over Internet Protocol (VoIP) will be the “killer application” at their Hotspots over the next 12 months.
