Mind the Gap - Or Not
Anyway, the US's leadership in CDMA led to the thought that perhaps the US isn't behind Europe at all in wireless, and the evidence supporting this began to mount. We have a variant of GSM available from Cingular, and triple- and quad-mode phones even allow roaming on a global basis. The next set of throughput enhancements for GSM, HSDPA (High-Speed Downlink Packet Access) are available today from Cingular, although the really fast stuff isn't available anywhere yet. Yesterday at CeBIT I saw Samsung's "Calypso" prototype, and HSDPA handset that can do 3.6 Mbps. In theory, HSDPA could reach 14.4 Mbps! I think it will do so in Europe and the US at roughly the same time, a few years from now.
We have ultra-wideband spectrum rules in places (and wireless UWB and USB were being shown here), but the rules for Europe won't be set until late this year or early next. WiMAX is evolving at the same rate in both geographies. Wi-Fi is everywhere.
So - is Europe ahead? Nope. No gap here, not any more.
BTW - my search for advanced battery technologies proved fruitless, even among the many battery firms from mainland China, that bastion of battery manufacturing. None of them had even heard of lithium-air technology. Oh well.
