Re: 1xEVDO now in Seattle

This used to be the case in the late 1990's, but the United States is
not as far behind as people assume.

The United States has been in pretty much sync with GSM technologies
as of late, and blowing Europe away with other competitive
technologies such as qualcomm's CDMA 2000.

The EU is reluctant to implement any competitive technologies other
than GSM for cellular communication.  A major CDMA2000 effort
(basically launched by carriers AND qualcomm because UMTS was late)
was stomped out in favor of adopting UMTS/WCDMA.  Uncompetitive
practicies in Europe are killing innovation and 3G/4G cellular.  Here,
in the US, the FCC could care less what you used.

The current revision UMTS/WCDMA is barely a 3G technology, much like
1xRTT is today.  Peak upload rates of 64Kbps and downloads of 384Kbps
are specified, but in reality, these speeds are rarely reached. 
Upwards of 200Kbps is typically seen.   1xRTT provides symetrical
153Kbps up and down, and typically reaches near the maximum speed in a
lot of markets I have seen.  100Kbps-130Kbps is not uncommon.

I am not going to even mention EDGE, because it is slower than 1xRTT
and a complete disappointment.

Asia has definately a more adoptive culture, so naturally they will
see the first implementations of future standards, but the US follows
closely behind.  Looking that the graphics you cited, most of the
users are 1xRTT anyway.  Same here in the US.  Sprint has had its CDMA
1xRTT service in all markets since 2002.  The one unusual thing about
Sprint is not only do they have some pretty attractive network
offerings, but they have been able to keep their new technology
adoption rates abnormally high.

There are a million different cellular technologies on the horizon,
but unless they are in production and widely used, it simply does not
matter.

People beat up the US for poor cellular coverage and slow technology
rollouts, but lets be honest guys, a lot of these countries are about
the size of one US state.  We have a lot of rough geography to cover
here.
