that we can bring in other customers. We need to plan for that. We also think that the return to society would benefi t from us managing to attract other organizations. These thoughts must be similar all around, where they have a nationwide system. “The challenge now is that so far we only have
one out of six phases that we have built. So the customers we will be trying to attract now are in the areas where we have built. That limits us geographically and it limits us also in which organizations we are talking to. On the other hand, some of the organizations we would like to bring in have a rather long cycle to get the funding and the money to be part of the network. “Some of the challenges we see are that the users

or a large network spread out over Norway’s thin population, usage by the emergency services alone will not be suffi cient to justify the huge cost of construction. So it up to marketing manager Jostein Hesthammer to recruit other bodies with a public service role as future sharers of the network. “We are trying to bring in health, fi re and police at the same time”, he explains. “So, in a way, we have a good starting point from the customer point of view, that we have the biggest organizations in Norway with us from the start. Many networks around the world have started as a police network and then tried to bring in the other ones.
“It would have been much easier to build this network
5–10 years ago, because now people are spoiled”, laments Mr Lyngstøl. “T ey can use the mobile network everywhere, and they expect so much in these terminals. “In Norway, it’s common now to have a smartphone.
Very few people (older people, and so on) use small, simple terminals. T ere’s been an explosion here and people expect everything from Day One. And of course, this is a network where the State is covering the cost. It is not a commercial network with millions of users generating cash.” A separate coverage problem resulting from Norway’s
mountainous terrain is its many road tunnels. TETRA enhancement has already been installed in 44 tunnels – but Mr Lyngstøl adds: “From what we know today, we probably have to build coverage in at least 200 tunnels in this country. At each of those projects there is something to mention. Some of these tunnels are very long.” Discussion continues on which ones are to be included in the roll-out, because coverage systems are not cheap. In some

would like to select radio terminals themselves, which has not been the case so far in the roll-out of the project. We need to establish better routines for offering equipment like this. We need some kind of recognition of certain brands and models so that we at least know what is entering our network. “Security is, of course, a huge issue in this network
– so we would still keep at least a controlling hand on the steering wheel.”
Sharing the network with a widening pool of potential users will help defray the heavy cost of construction
tunnels, the traffi c load is light, yet the consequences of an accident could be serious.
Deploying TEDS Wireless data coverage is another feature today’s mobile users expect, but DNK intends to begin cautiously by introducing it to just 30–40 per cent of the network, to gain experience. “We will see how successful that is and what we will do with the rest of the network in the future”, Mr Lyngstøl says. “When we started the specifi cation work here, you had
maybe 14·4 kbit/s in the GSM network. But this has changed dramatically. We expect to get approximately 80 kbit/s TEDS and I think I can say that there is very little experience on the supplier side here. For instance, we have to be sure that the data user – let’s say he is within a TEDS coverage area and then he moves out of the TEDS coverage area – we have to be sure that he can be handed over to a multi-slot packet data area, that we have all over the country. And the next question is what throughput are you getting within TEDS and out of TEDS.
