Rarely I get to brag, but here's a system with an ASIC in it that I
designed...

Inneresting.

Silicon-based sensors are fascinating, particularly the MEMS one (which
this ain't, I think, but still...).

Sensors were external.

The MEMS stuff requires heavy physics, and seems to be on the mechanical
engineering side of things.

Neat, 0.8 mA.  I can see GPS applications, but  cell phones not so much.
I just donít see a practical app in the phone, maybe the Japanese will
find it a novelty.

Cheers

0.8mA was quite the struggle.  Everything you can think of was able to
be powered down.

Actually, When I did the design (February to December 2007) I didn't
have a clue about the application(s), just the required specifications
;-)

Cell phones need GPS in order to give their location to 911.  They
already have a display and UI...  So anything you can do on a GPS
toy, you can do on a cell phone.

Phones also have network connections.  They aren't really phones
any more so much as platforms for collecting junk/hacks and goodies.

Cell phones get their location by talking to the nearest fixed
transmitters - which is what defines the cell they are in. They don't
need GPS to do that. The basic hardware doesn't translate this
location into GPS coordinates, and some cell-phones - such as my Mio
A701 - have separate GPS hardware.

You have to pay extra to be able to exploit the network connection.

I thought the FCC had mandated GPS.  Thanks for making me do some
investigation.  (I knew about the triangulation, but I didn't think
it worked very well.)

Here is the best URL I found:
  http://library.findlaw.com/1999/Nov/1/130152.html

Quick summary:
  The FCC mandated accuracy.  The cell phone companies could get
that by either upgrading the gear at all their towers, or upgrading
all their cell phones to use GPS.  Some went each way.

That is the US situation now. Here's a lawyer's view of the
geographical information available from cell-phone company records in
the UK and Australia.

Ain't that the truth!  I'd like a phone with a full keyboard (for
E-mail), but NO camera... _many_ locations I visit forbid cameras
inside the facility.

What do they do about cell phones?  Do they check for them?  Do
they know which ones don't have cameras and let them in?  Or just
prohibit all cell phones?  ...

Mmm, similar to some places I visit. Others just ban all non approved
cell phones (I.E. not company issued ones)

Wish I still had my old analog nokia. Was cheap and the battery never
died. No camera either.
That was before ATT sold off its Wireless business. Perfect for the G
job.
