<<PS It might surprise people to know that current top line GSM handsets use 4Mbyte of FLASH, 256K RAM and contain close on 1 million lines of code. Compare this to early PC's of 15 years ago.>> w, Are you familiar enough with PC hardware/software to provide a comparison as to why the GSM call model is difficult? This might be asking a lot, but it would help the computer guys to understand. Thanks, Cooters

It might also suprise many people that there are actually about 15 differnt flavors of GSM and the handset must be abel to decode the software stack for all of these wihtout a hitch. Each of the original 13 countries in Europe insisted on having their own GSM standard, so the original SW coders had to create actually 13 sets of real time code. Later as more countries were added this got to be more versions. finally they agreed (after loosing ground to CDMA) that this was crazy and kind of standardized on the last 15 or so. It is getting this SW stack right which is tough, altough there are companies out there which lic this stack for a royalty and IF QCOM wanted to proceed with a GSM phone, they could lic the code from these companies. there are a few companies around who have tried to make a GSM core and SW stack and have worked at it for more than 3 years and failed badly.
