What Is SNPP

   SNPP is a simple way for delivering wireless messages, both one and two-way, to appropriate receiving devices such as pagers and cellular phones. In its simplest form, SNPP provides a simple way to implement a "shim" between the Internet and a TAP/IXO paging terminal. In a level 3 form, it receiving end-to-end acknowledgments and replies from a two-way messaging device such as ReFLEX units.
    Gateways supporting this protocol have been in use for well over a year at several commercial companies such as Nextel and American Messaging, and private businesses as well. A list of companies that currently have SNPP Gateways can be found here.
