'[EE] : Cellular Phone Interface'
2001\06\24@125831 by Chris Carr

For a project I am doing I would like to be able to use a cell phone and
connect the phone to a modem.  Preferrably the modem would be a serial port
type, but PCMCIA could be acceptable.  I've searched around and found one
PCMCIA modem that does this and interfaces to Motorola cell phones and
Nokia.
But I would like alternatives.

My questions are:

1) Does anyone know of a interface between a cell phone and a modem?
2) Are there modems available, specifically serial port ones, that are
available?
3) If price is prohibative and I need to make my own interface, where can I
find data sheets or specs on cell phone pinouts and protocols. The design
would be based around a PIC.

Robert,

I suspect that you have used the Search Engines looking for modems and drawn
a blank. In fact digital cell phones do not use a modem, the data stream is
fed directly into the digital stream on the cellphone network. Try looking
using keywords such as Nokia Motorola Data Interface, Data Cable Kit,
cellphone data protocols.

Incidentally the Nokia 9000 series of handsets (I believe the 9110 is the
current model) does not require a special interface as it accepts RS232.
Nokia supply a lot of development software for these machines.

I think from what you say in point 2 below, a cellular engine might do you.
Basically what they are is a cellphone with either an RS232 port or some
other kind of comm port on it. They are intended as devices for integration
into other products, and offer the full set of - usually GSM - protocols and
standards.

Motorola have a single band one called the D10 and a new triple band one
called the D15.
Ericsson have a couple, the GM22 and GM25.
Siemens have several, the 8 Watt A20, the M20, the new TC35, and the MD32
DECT Engine.

I'm sure there'll be a few others available too as it should be quite
profitable for telematic/telemetry uses compared to making boxes for the
consumer market.

you can take a nokia cellphone with a built-in modem and the datacable, gives your rs232 access to a modem, I used a terminal program on my Palm to access my nokia 6210 via IR and that works great
it accepts standard AT commands.
including some special ones to read/send SMS.

the specs for the SMS is on nokias website.

I'm sure ericsson/motorola/etc offfer similar solutions.

Robert,

Check this website.  They have an interfaces for cell phones that makes them
work like a regular phone line.  This appeared about a month ago on the
list.  Using this device and a regular external modem might work.

Hope this helps.

There's never enough time to do it right, but plenty of time to do it over.
