"Designed by Motorola, FLEX is the highest speed paging protocol available today.
It's quickly become the worldwide paging technology, and has set a new standard for the future of paging.
FLEX defies technological barriers created by other paging protocols (ie. POCSAG, GOLAY)."

The FLEX Technology: Paging Protocol page, is designed as a resource for everyone in the telecommunications industry and "underground" scene to learn more about the less known paging protocol. Over the years the POCSAG protocol has become an interest to many hackers and phreakers which started it off by the infamous hacker Erik Bloodaxe who wrote the extraordinary guide to the POCSAG protocol titled 'The Wonderful World of Pagers' (in Phrack 46-08).

Now there's a new breed of techno-junkies who thrive on knowledge. We know that project POCSAG is finished. It's been done. But what about FLEX Technology?

This protocol has taken over where other pager protocols left off. We see that over the past eight years FLEX has grown at an astronomical rate and very few people appear to be exploring it.

That's about to change...
