Compiled Wireless Markup Language

In networking for mobile devices, WMLC is a format for the efficient transmission of WML web pages over Wireless Application Protocol (WAP). Its primary purpose is to compress (or rather tokenise) a WML page for transport over low-bandwidth internet connections such as GPRS/2G. WMLC is apparently synonymous with Wireless Application Protocol Binary XML (WBXML).
