I'm a newbie to the world of GSM and have been thrown into having to solve a problem which I hope someone might provide some guidance. I'm researching the various ways of detecting mobile devices and have a system that works for devices which are wifi and/or bluetooth enabled, but I need to resolve the case where both are not enabled. The task is to not communicate with the mobile device but to uniquely capture the date/time that device was in a proximity. From my readings, is it possible to create a "stripped down" BTS system that actively listens for Um traffic and if so would that uniquely identify the mobile device?
I looked at the range network dev kit:

For my needs, I'm wondering what is the best approach.
Whatever suggests or help you can provide would greatly be appreciated.
