Mobile Radio Usage
The Problem
As part of the British Department of Trade and Industry (DTI), the
Radiocommunications Agency monitors and manages public and private
radio transmission throughout the UK. The Agency set out to
evaluate activity in the VHF (very high frequency) PMR (private mobile
radio) high band used by emergency medical services, local government
councils and private businesses. While monitoring user occupancy in
the VHF PMR was a fairly straightforward project, analyzing the volume
of acquired data proved daunting.
High Volume Data
The Agency's Mobile Monitoring Section set up six unattended monitoring
systems between the city center and the M25, the major highway artery
encircling the metropolitan area. A seventh manned monitoring system
was activated in London's Hyde Park. For thirteen weeks each of these
monitoring systems collected 12 megabytes of ASCII data on more than
300 radio channels.
Finding the Right Tool
According to the Agency's Quality Manager, Kevin Mylan, the spreadsheet
and database software they were using "proved to be incapable of
analyzing the vast amount of data we were gathering and so the search
began for new software."
