New Study Identifies Alternatives for Public-Safety Broadband
10th Oct 2018
A new dissertation aims to identify the most feasible alternative for a broadband public protection and disaster relief (PPDR) mobile service and uses Finland as a verification case. According to the analysis, the solution creating the most socioeconomic benefits would be a hybrid network.
Matti Peltola outlined the socioeconomic benefits as a measure for making the valuation of governmental infrastructure services. In his thesis, he analyzed four different network variants —dedicated; commercial, but fulfilling PPDR requirements; a hybrid; and existing narrowband plus commercial best-effort network — in five Finnish provinces.
The net benefits of the alternatives are defined with each province having a different population density from 3.3 to 2,785 people per square kilometer.
The study found that the PPDR mobile service should be implemented using the commercial networks as platforms in sparsely populated areas and the dedicated network would be used in densely populated areas with the exact threshold point depending on local circumstances.
The same nationwide fee for mobile users in commercial networks would mean that users in sparsely populated areas are subsidized. Moreover, the time boxed use of existing narrowband PPDR networks, in parallel with commercial best-effort networks, in certain sparsely populated areas, would increase socioeconomic benefits.
Furthermore, when the PPDR broadband mobile service is based on a commercial network, and if the part of that network is still based on 2G/3G technology, the tight voice call setup time cannot be fulfilled in the 2G/3G network. The call setup requirement can be solved using the existing narrowband network in parallel in those areas until the whole network is updated to 4G/5G technology.
