Keeping Commuters Connected: How We Helped Telenor Provide Coverage to the Oslo Metro
Cobham Wireless worked with Telenor to provide a customised multi-band, multi-operator distributed antenna system (DAS) to enable seamless mobile phone usage inside the trains and station of the metro.
The Challenge
Norway’s capital city, Oslo, has a metro network consisting of six lines totalling 86Km of track that all run through the city centre, connecting 97 stations over 14 boroughs.
The Oslo metro is utilised by 85 million commuters every year. With the mass proliferation of smartphones, all commuters expect to make calls, text and browse the internet while on the move from one location to another. Therefore it’s just as important to provide a smooth coverage handover from the station to the tunnel as it is to provide coverage in those individual areas.
With an environment like a metro, there are multiple challenges from limited space for the equipment to extremely high capacity demand, but how do we overcome them?
Due to our extensive experience providing coverage to 70% of metros worldwide, Telenor, a leading mobile phone operator in Norway, approached Cobham Wireless to ask for guidance when choosing and designing the right solution for this complex environment.
Telenor were joined by two additional mobile operators, Netcom and Mobile Norway, making this a multi-operator project. All three supported the project financially, with Telenor as the project developer/owner and our main point of contact during this deployment.
The Solution
On review of the project, the Cobham Wireless team determined that a customised multi-band, multi-operator distributed antenna system (DAS) would be needed to meet all the requirements…
