Mobile networks constantly change with implementation of new technologies, optimisation of existing networks etc., and it is very important that the DAS facility inside a building works with the macro network outside the building.
In the spring of 2015, Ramboll has completed a comprehensive benchmark of two mobile operators, measuring voice and data transfers on both 2G and 3G networks.
In the autumn of 2015 Ramboll performed a comprehensive analysis of the mobile coverage in a newly-constructed hospital wing. All operators and mobile technologies supported were measured in the frequencies supported by the DAS. The goal is to achieve 100 % coverage all over the facility. The analysis ensured that the handover, when entering and leaving the building, functioned correctly.
