My current toy is a freebie demo Sprint Vision phone (the spiffy Samsung A920). It does so many things, from music to live TV, that I’m sure it will cause an uptick in hospital emergency visits in regions where it is rolled out. Anyway, more on that later.
In the interim, and in a similar vein, there is some very worthwhile reading in the current IEEE Communications magazine on the evolution of 3G technologies. There is good stuff on symmetric bandwidth requirements and related solutions.
