Wireless Communications Transfer Protocol

Wireless Communications Transfer Protocol (WCTP) is the method used to send messages to wireless devices such as pagers on NPCS (Narrowband PCS) networks. It uses HTTP as a transport layer over the World Wide Web.

Development of WCTP was initiated by the Messaging Standards Committee and submitted to the Radio Paging Community. When the first proposal was received, a sub-committee was established to improve the protocol and issue it as a specification. The sub-committee was moved into the PTC (Paging Technical Committee) which is a volunteer committee composed of industry representatives. The PCIA (Personal Communications Industry) accepted the first full release and adopted the protocol as a PCIA standard. The current version is WCTP 1.3.
