Mobile network coverage of the highways

CTU performed measurements of the mobile network coverage of the highways in the Czech Republic. This was a follow-up to the previous one of the railway corridors.  The coverage of the D8 highway proved to be the biggest issue for the operators regarding the coverage.

The measuring vehicle went through all the highways in both directions and the measurement was performed on a per-second basis. Thus, CTU obtained the data with a density of every fifteen meters.

The data showed that there are sharp lines between the covered and uncovered parts. In case there are more consecutive places like these, users can view the whole area as the one without the coverage due to a lack of time for the mobile telephones to get connected.

The operators´ commitment from the spectrum auction for the LTE networks stipulates the following obligations. The operators are obliged to cover 50% of the highway network in total until 5 years (in 2019) and to cover 100% of the highway network until 7 years (in 2021) after the decision on block allocation of frequencies became effective. The measurement proved that all the operators have already met the first obligation.    

The mobile signal passes through the bodyworks of the vehicles easier than through the constructions of the railway wagons. The 6 dB average damping of the bodywork is presumed. With regard to this fact, the difference between the indoor and outdoor sufficient coverage is in a range of a few percent or less.

CTU provides the data resulting from the measurements in open data format for further processing. It has been preparing a visualisation of the results in an interactive application which will be available on the websites.
