re: the number of 3G 1x phones out there

==========

Hey engineer,

Remarkably, there are rather sad - and deservedly frustrated - souls who still attempt to disparage this impressive collection of handsets as not being 3G...

Ironically, some of them have previously and consistently exhibited a hearty affection - or perhaps fetish - for European standards bodies, including the ITU, who dictate and define 1x as 3G.

I wonder how they manage the spiritual conflict? Perhaps they simply feel betrayed...

However, a greater challenge awaits these conflicted souls (or rather may await them, if they're very, very lucky, in 9 months or so) if NOK's 128kbs max, and truly 2.5G, wCDMA wonder graduates to commercial service.

For those who may not recall, this is the handset that, on September 26, NOK lacked the balls and capability to trial on Sonera's network - and instead spun pundits across town, conveniently out of range, cloistered in a Helsinki museum.

But it may not be a challenge for them at all. By all appearances, they've grown accustomed to contradiction, and are most skilled in the application of real-time revisionist history.

Their problem, however, is that fewer and fewer people will listen.

re 450mhz chips

Hi engineer,

I assume that the 450mhz phones are using non-zif msm chipsets (i.e. 3xxx and 5xxx). Will they all work with appropriate SAW filters?

The other question I was hoping you could address ... Is it practical to incorporate 450mhz into the 6xxx series?

I briefly remember reading somewhere something about the filters for 450mhz being large (in surface area?). Is this correct?

If you (or others) could post thoughts on multi-mode zifs (i.e. combinations of 450mhz, 800mhz, 1800mhz, 1900mhz and 2100mhz), it would be appreciated. Obviously, 1900mhz and 1800mhz are today's reality. What needs to be considered in extending that reality down to 450mhz and up to 2100mhz?
Am I correct, in assuming that the current batch of 6xxx zifs don't support analog/cdma at 800mhz (I'll check this out later today)?

Thanx to whoever posts whatever related info.

Trevor
