Over at TheFeature there is a great piece on Software Defined Radio. For a long time this has been flagged as the ultimate radio as it selects the best network to use dependent on the type of service you require and what spectrum is available.
This could see the most effective system giving broadcast qualitity services which would make BT's Bluephone project look as sleek as a barge!
The problem is that the technology was outlines many years ago and working parties in BOTH the US & Europe set the standards for SDR over two years ago and still we are no closer to a commercial device. Could it be because the manufacturers are busy building 3G, Bluetooth, WiFi, GSM chip based products which they need to make revenue from for the R&D spend?
I don't expect to see any inteligent radio device before my five year old finishes secondary school, but she might get one when she finishes University!
