WTP provides functions similar to [[Transmission Control Protocol|TCP]], except that WTP has reduced amount of information needed for each transaction (e.g. does not include a provision for rearranging out-of-order packets).<ref name="novell-networking-primer"/> WTP runs on top of UDP and performs many of the same tasks as TCP but in a way optimized for wireless devices,<ref name="novell-networking-primer"/> which saves processing and memory cost as compared to TCP.

It supports 3 types of transaction:<ref>{{cite book |last1=Mann |first1=Steve |last2=Sbihli |first2=Scott |title=The wireless application protocol (WAP) : a Wiley tech brief |date=2000 |publisher=John Wiley |location=New York |isbn=978-0-471-39992-6 |page=39 |url=https://books.google.com/books?id=EbyMMPt894EC&dq=wtp%20packet%20reliable%20two%20way&pg=PA39 |access-date=26 February 2022}}</ref>
