*'Tower of Babel' technology nears
The problem of compatibility between wireless devices is being addressed 
at an international conference this week.  Scientists will be discussing 
what has been dubbed "Tower of Babel" technology - software that can 
converge different wireless gadgets into a single device. The aim for 
Software Defined Radio (SDR) is to be able to translate and understand 
any kind of radio wave signal, such as 3G or wi-fi.


*Intel's UWB Chip and First Customers*

Intel <> has worked behind the scenes on 
ultrawideband standards with the WiMedia Alliance 
<> but this week at the Intel Developers 
Conference finally revealed its initial plans for a UWB chip. And while 
on the surface it doesn't appear too exciting, you can never count out 

The first UWB from them is the Intel Wireless UWB Link 1480 media access 
controller (MAC) silicon, a host solution suitable for use with third 
party physical (PHY) layer chips. Intel's initial partner here is Alereon.


*Wireless USB Devices Coming This Year*

SAN FRANCISCO -- Amid the Itaniums, Xeons and Core 2 Quads here at the 
Intel Developer Forum, perhaps the sleeper hit will turn out to be a USB 

The USB Implementers Forum (USB-IF) announced it is now ready to certify 
devices for compliance for the Wireless USB specification, which allows 
for USB data transfers without the rat's nest of wires found on so many 

In a way, it's similar to Bluetooth, which hasn't really found much use 
beyond wireless cell phone earpieces.

The problem, said Jeff Ravencraft, chairman and president of the USB-IF 
and technology strategist at Intel, is that Bluetooth only offers 1Mbps 
data transfer rates, while USB 2.0 can reach 480Mbps.
