Handheld device useage in Electronic Trading

Imported from previous forum

Where can I get info about current useage of handheld devices in Electronic trading? To be specific, I want more info about WAP and its useage in FIX PROTOCOL ( if any ), security contraints in this issue and related info on similar lines.

    Could someone point me to the location where I can get more info on this topic?  

Thank You,
Raj Bandu.

HP and CME have been working together along with a solution that seems to be exactly the one you informed. Follows the HP media folder:
