Introduction

The goal of the GSM Activity Scanner project is to develop a low cost GSM Activity Scanner.. The GSM Activity Scanner project originated as feasibility study for the more advanced GSM Radar concept.

The GSM Activity Scanner will be able to indicate the amount of phone traffic in the region where it is operational. Since the device is low-cost, it will be possible to place them on several places and since the devices are connected to a PC the information can be gathered on a central website.

Possible applications are detecting popular providers and/or detecting peaks in phone traffic related to public events.

The current design is based on a modified GSM and some glue logic to enable interfacing the modified GSM with a PC over RS232. The GSM Activity Scanner is operational and some results are available in the Scanner Results section. Information on ordering one of these GSM Activity Scanners can be found in the Order Scanner section.

A future design replaces the simple glue logic with a more advanced FPGA, which allows to connect multiple modified GSM's to the same GSM Activity scanner and to scan faster. The interface of this design with the host PC will be USB.
