TECHNOLOGICAL AND ECONOMIC BARRIERS AND ISSUES
The capabilities of existing (and possibly future) narrowband and wideband dedi-
cated mobile networks currently used in the PPDR sector will not be sufficient to 
meet the envisaged future requirements. This is inevitable, unless a steady growth 
approach is introduced where PPDR operation methods change gradually, voice re-
mains the dominant method of mission critical communication, and existing data 
applications continue to be used alongside voice (with a gradual increase in use). 
However, this is not suitable in the longer term since there is already growing evi-
dence of changes in working methods and trends within the PPDR sector that suggest 
that this path will not match future demands. A new generation of mobile broadband 
service is required to accommodate the range of future data, image and multimedia 
applications that PPDR users demand. The options for delivering this new generation 
of services are to make use of upgraded commercial networks, or to develop a new 
generation of dedicated mobile broadband networks for exclusive public safety use. 
While the new generation of data service could theoretically be delivered through 
upgrading and re-engineering commercial networks, there are certain barriers, which 
range from technical to cost and commercial considerations, that might make it dif-
ficult to achieve in practice. These include the following:
• The PPDR sector requires very extensive geographic coverage as well as in-
depth coverage penetration inside buildings, irrespective of location, which does 
not match the typical roll-out requirements of commercial network. Commercial 
operators typically invest in coverage where populations exist, and capacity is 
designed to maximize revenue generation in those areas, with little incentive to 
invest in areas of low density population.
