GPRS and WAP Neither one is really anything without the other, this is a must to consider when thinking about either one. The key thing is - being constantly connected through GPRS (without draining the battery, some problems with commercials here) - low cost possible as only extra capacity of network is needed but additionally high burstrates and additionally high streaming rate (probably for cold cash) This is why a special protocol is needed, very short messages back and forth when nothing or little, happens, something WAP can do, other present protocols cannot. (battery-battery-battery for mobile devices) Eg, WAP has been specifically designed to do a lot of smart caching of repeated, "empty" messages to save transmit power and capacity. This is also one of the more difficult things to handle, both for those building the standard and especially for "high" level programmers who do not really grasp what actually goes on (deep down at the hardware level) and additionally to make the whole network plus devices work together. But to "analyse" GPRS and WAP separately is just a way of saying one hasn't understood the whole thing.. Ilmarinen.
