“…Network availability depends on network technical capability, on the used applications within the network and on the number of users, which may overload the network. But many other issues can also influence the availability, such as cyberattacks, unreliable ownership, unsecured physical location, poor network coverage, unreliable or incapable personnel (Peltola and Kekolahti, 2015).…”

“…If commercial networks are utilised for the deployment of mobile BB for PPDR users, both the financing and radio spectrum issues will be more easily resolved. The commercial networks fulfil functionality (3GPP, 2013), security (end-to-end encryption), resilience requirements (multiple alternative networks) and communication performance issues (high bitrates and wide coverage), but the question has been raised whether commercial networks can fulfil the availability requirements of the authorities (Swan and Taylor, 2003;TCCA, 2012;Peltola and Kekolahti, 2015). The priority functionality has been developed for LTE technology (3GPP, 2016) to enable prioritised communication for certain user groups -if needed and allowed by regulators and operators.…”

Purpose The purpose of the paper is to define the best deployment alternatives for a public protection and disaster relief (PPDR) mobile network service – the implementation alternatives being either a dedicated network, a commercial network or a hybrid of the two network types. The selection criteria are based on the social benefits that the PPDR mobile service is expected to bring to society. The critical parameters are population density and service availability, which both directly relate to the socioeconomic benefits achieved by providing broadband (BB) mobile services in various demographic areas. Design/methodology/approach A causal loop model has been developed to define the socioeconomic benefits of the PPDR network, the parameters being population density, service availability, socioeconomic value of the service and the costs of the network. The network solution alternatives are studied using the Finnish PPDR network as a reference – analysing various areas of the country with differing population densities from remote, rural and more densely populated suburban and urban areas. Findings Socioeconomic value is a common measure for assessing the value of governmental investments; population density has a strong impact on the optimum deployment alternatives as the socioeconomic value is directly proportional to this variable. The flat nationwide fee of the mobile users means that the users are subsidised in sparsely populated areas – and overcharged in densely populated areas. This is the main reason why the commercial network seems to be most feasible in rural areas, whereas the dedicated network works best in urban areas. Based on the case study, the commercial network is most preferable up to the point when the population density reaches 50-125 persons/km2. After that point, the dedicated network becomes more appropriate. Proposals are being made to improve the availability of the commercial networks enabling them to serve as a PPDR network: ensuring priority functionality and a protected power supply; allowing PPDR subscribers the exclusive use of one of the 700 MHz spectrum bands in restricted, critical areas; and extending use of the existing narrowband PPDR network in areas where communication availability is crucial. Originality/value On the one hand, the financing of BB PPDR mobile networks is an unresolved issue in many countries. On the other hand, the ability of commercial BB networks to provide better quality of service is improving, making viable the alternative to subscribe for radio service from a commercial operator. Therefore, the feasibility study on how to provide an optimum mobile BB service for PPDR organisations is of real value at this time.

“…Peltola and Kekolahti [30] use Bayesian networks and expert knowledge to perform a risk assessment of the Finnish TETRA PSS network, where several risk sources and controls affect the availability of the network. Bayesian networks have been also used in several research papers to model interdependent information security vulnerabilities as attack scenarios [13][14][15]17].…”

This study comprises an information security risk assessment of smartphone use in Finland using Bayesian networks. The primary research method is a knowledge-based approach to build a causal Bayesian network model of information security risks and consequences. The risks, consequences, probabilities and impacts are identified from domain experts in a 2-stage interview process with 8 experts as well as from existing research and statistics. This information is then used to construct a Bayesian network model which lends itself to different use cases such as sensitivity and scenario analysis. The identified risks'probabilities follow a long tail wherein the most probable risks include unintentional data disclosure, failures of device or network, shoulder surfing or eavesdropping and loss or theft of device. Experts believe that almost 50% of users share more information to other parties through their smartphones than they acknowledge or would be willing to share. This study contains several implications for consumers as well as indicates a clear need for increasing security awareness among smartphone users.

“…Studies have already been done to demonstrate, which functionalities are needed to improve the performance of the PSE agencies (Borgonjen, 2012). Studies have also been conducted to understand the best roadmap to implement high speed mobile data communication for PSE (Peltola, 2011).…”

“…the networks already exist and the coverage is excellent. Nevertheless, the commercial mobile networks seem to have some fundamental problems if these networks are to be used for PSE mobile communication (Peltola, 2011), one of the most critical problems being that the networks become jammed in disaster situations (Swan & Taylor, 2003). For this reason, it has been concluded that the utilization of the commercial mobile networks as a media for PSE mobile communication is possible for non-critical communication.…”

We calculate the added value for society of Public Safety and Emergency (PSE) agencies when they have a dedicated mobile wideband/broadband network to complement the offering of the existing PSE mobile networks. The principles of benefit valuation are demonstrated. The basic PSE operational processes are divided into operations. The operations of an organization can be modelled and the sub-tasks of operations utilizing improved communication tools and applications can be redefined. The modelling and the definition of the costs of every operation can be done using the System Dynamic analysis and Three Viewpoint Model analysis (Martikainen and Halonen, 2011) tools. After that the costs of the new mobile network service are estimated; the alternatives analysed include the dedicated TEDS (TETRA Enhanced Data System) and LTE (Long Term Evolution) networks. The proposed approach gives answers to the three following questions: (1) is there any benefit in building a new high speed mobile data network for PSE agencies; (2) what is the Net Present Value (NPV) of the business case including the costs of the new PSE wideband/broadband mobile network and what are the social benefits that the new network makes possible, and; (3) how can the benefits of mobile broadband/wideband communication be correlated to population density in order to create additional value for society.
