The ultimate counterargument is always that there will be situations when none of the commercial networks will function. They can be blocked due to other traffic, there are areas where commercial networks don't exist or power could be cut off. In these cases there remains a need for priorisation, QoS or even dedicated networks. Different dedicated LMR technologies, like TETRA, need to be there as a back up also for data.
There is, however, a chicken and an egg problem here. The broadband solutions are needed in daily operations today. Should we postpone the introduction of broadband data to PS because of possible rare incidents or could we introduce a concept that works now and can be upgraded to meet the requirements of future as needed regulatory decisions are made? I think broadband should be introduced today and upgraded later. But not just any kind of a solution. We need a future proof solution that is capable to meet most of the demands of criticality today!
Overall Picture of the Needed Router Solution
- Image and file transfer
- Database queries
- Location based services
- Biometric checks
- and ultimately streaming video
These services can be used in critical environment only by using routers that are specifically designed for the purpose. This includes special hardware, software and management features.
