arthur, i don't pretend to be as market savvy as Greg, although followed his same choices. but one company which is not public yet, but which stated they will be coming public is Golden Bridge Technology (GBT). their ASIC based matched filter process for information transfer/receipt is relevant to both 3g and 4g. they claim to have sent info up to 36 mbps. their ASIC doesn't become "fully operational" until 2mbps and can send without significant degredation up to 10kilometers (they've sent info using TDMA, CDMA, and B-CDMA coding). no one company has proposed such high standards yet. and it's currently operational. they have contracts with AT&T and some other knowns. but, in fact, their claims appear so outrageous that some have called their claims "hooey". QCOM, by contrast, is working on a system expected to be operational by 2002 which will transmit up to 1.5mbps (Q uses correlator filters which by nature can not handle current information overload demands - speed is necessarily acquainted with increased data given proper spectrum allocation - obviously, to transmit video over the net you'll need a ton of bandwidth and a ton of speed- both which GBT says they can deliver). i've called them on several occassions to discuss their claims - their engineers chuckle at the naysayers, so there's been no pullback whatsoever on their part. their contract with T also carries weight.
