Because you are talking abourt it....
I have a GSM-Modem (costs around 50 Euro) which suppoert HSCSD and
GPRS and sit on the serial port it allows connections up to 56kBit.
I was searching for EDGE/UMTS ones...
..but found only overpriced PCMCIA cards for 350-600 € plus the
price for the PCMCIA/PCI adaptor.
Do you know, whether Serialport EDGE/UMTS modems exist?
I am customer from Philips Semiconductor and I have a full
specification for a PCI-GSM-Modem (GPRS, EDGE, UMTS) but not the
time and technical equipment to do it currently my own...
Price for the micro chips and the production for the cards are
around 80 Euro for a working PCI-GSM-Modem if I produce 100 pieces.
So, the PCMCIA stuff IS OVERPRICED, because I am electronic engineer
and know what I am talking about...
Oh yes, I was already thinking about an Open-Hardware-Project like
the Open-Source-Software... We can develop Hardware which works
100% with Linux and other OS whith out head-stands.
