Telefonica Deutschland has announced that it is connecting its 5G mobile stations via high-capacity microwave radio relay systems where no fibre-optic infrastructure will be available in the foreseeable future. Thanks to technological progress, innovative radio relay solutions now support bandwidths of several gigabits per second. Reliable transmission of mobile radio signals from mobile radio systems to a core network almost in real time, as required by the 5G mobile radio standard for broadband applications, among other things, is therefore also possible via directional radio. In rural areas in particular, Telefonica will therefore increasingly use high-capacity 80GHz directional radio (‘E-band’) in addition to fibre-optics, depending on the location, when expanding its 5G network.
‘By shifting the previously applicable physical limits for microwave radio relay systems and due to the high flexibility as well as the cost and time savings, the microwave radio relay solution thus supports the goal of a rapid 5G network expansion,’ a press release from the company said. Telefonica is aiming to supply the entire population of Germany with 5G by the end of 2025.
