Norwegian Roads Agency
Deploys Hardened Wireless Network
NPRA upgrades roadside monitoring stations to Cisco wireless machine-to-machine gateways for remote manageability, reliability, security.
Business Challenge
Electronic devices generate heat; often, they generate enough heat to threaten their own proper operation, even to shut themselves down. So for most network managers worldwide, maintaining a sufficiently cool environment for their equipment is a constant concern. But not always, and not everywhere.
Norway is one of the northernmost countries in the world. From Kristiansand in the south (at 58° latitude) to Honningsvag, the country’s northernmost city (71° latitude), is a drive of 1400 miles, or 2260 kilometers. So Norway’s countrywide network of roadways traverse a range of climates from cool, to cold, to very cold indeed.
From April through September, monthly average temperatures range from 49° F (9.4°C) in April to 71° F (21.7° C) in July; winter averages (October through March) are mostly in the 20° to 30° F (-6.7° to -1.1° C) range. Lows below the freezing point can occur in all but three months of the year anywhere in the country, and in the far northern reaches of Norway winter temperatures can plunge well below freezing.
In short, only about 30 percent of the time is the average ambient temperature across Norway within the normal operating range of typical networking equipment. Read more on Cisco…
