| A bletcherous protocol stack which basically reinvents TCP/IP from the ground up, under the guise of "wireless is different" (kind of ironic considering that TCP was invented because of the radio network on alohanet). As a result, you have people reimplementing all the mistakes that were made in the history of the internet, but in a tenth of the timespan.
This would be understandable if WAP (more precisely, WDP and WTP) actually did anything that UDP and TCP didn't do. As it is, it's a hodge-podge of ideas borrowed from the IETF and misimplemented by a closed committee.
