Peter Wayner has a story about a WiMax rollout in Baltimore in the US. They seem to be getting 6 Mb/s download and 1 Mb/s upload. This is termed a `4G' network (which might just be marketing speak).
In India, Thomas K. Thomas has an article on price cuts by Airtel. My sense is that we're in for a big crash in prices of bandwidth through a combination of improvements in prices of wired services and the rollout of 3G which is now a credible alternative to land lines.
The exciting new development on mobile bandwidth is the CDMA EVDO devices being sold by Reliance and Tata Indicom. Last night I did a bulky upload and it worked at 350 kb/s without interruptions. Naman Pugalia and Alok Parekh are measuring the performance of Reliance and Tata Indicom at locations all over India. The picture so far is that EVDO is a lot better than dialup (or CDMA 1.x) but it ain't really fast.
