Why are Wi-Fi hotspots making a comeback?

Recent figures from In-Stat suggest that hot-spot usage surged in 2009. In-Stat predicts that usage will increase 47% in the year to 1.2 billion – presumably it means sessions, although that isn’t clear in the release. The analyst says that the turnaround for the market has been driven by mobile operators who are looking to offload browsing traffic from their 3G networks onto Wi-Fi. In some Wi-Fi hotspots smartphones already account for the majority of sessions. In the UK, mobile broadband networks such as 3G and HSPA overtook Wi-Fi as the most popular way of accessing Internet on the move back in September 2008 – according to Point Topic.
So why are we looking to Wi-Fi again for browsing on the smartphone? Part of the reason is simple usability, because it is much easier to access Wi-Fi network on the new generation of smartphones. But there is also a network reason: new mobile internet browsers – such as Safari and Opera – are also much more multimedia rich, which puts strain on available network capacity. Although HSPA is becoming increasingly widespread, coverage is still very patchy in rural areas and browsing the Internet or downloading email over GPRS is truly a painful experience. You could, therefore, consider the surge in Wi-Fi use as an indictment on the quality of 3G networks, because operators have been forced to offload traffic. Essentially, however, the underlying network technology should be irrelevant to the user. Operators just need to make sure that they provide the necessary bandwidth by whatever means if they don’t want their users to churn.
