I think the last time I was really excited about EDGE, the data transmission technology of GSM, was back in 2010. Back in 2008 there was a lot of activity around Evolved EDGE with it's main feature bundling several carriers to increase single user speeds. Since then it has become pretty quiet.
Back in 2010 I had a brief personal resurgence of interest while having been in Thailand and depending on EDGE for connectivity. Since then, however, 3G and also LTE networks have increased their coverage areas in Europe and the US considerably. That's good as web pages are becoming ever more complex and require tons of data to be downloaded. In addition, cloud services that are becoming ever more popular and require more and more data being shuffled back and forth.
So in retrospect my interest in EDGE has noticeably diminished in the past 4 years up to the point where I wouldn't even consider it as a kind of spare backup. It has become too slow for how I interact with the network today.
I also haven't heard much from Evolved EDGE since back in 2008 so I don't think there's a lot of activity to bring this from paper to practice. Certainly not in countries that already have LTE deployed. So I can but just wonder what the options are in evolving countries with little 3G or LTE coverage yet!? I have no hard facts but I have a feeling that Evolved EDGE is not the way they will take either.
