MWC 2019 - Interview with Magnus Frodigh - Head of Research @ Ericsson
Ovidiu Mățan: Hello. We are at MWC (Mobile World Congress) in Barcelona and we are talking to Magnus Frodigh, Head of Research at Ericsson.
Magnus Frodigh: Hello.
Ovidiu Mățan: 5G seems to be the trend at MWC Barcelona. How do you see 5G adoption? Can we leverage any of the existing infrastructure?
Magnus Frodigh: We are seeing a rapid take-up of 5G. We started the standardization for this 5-6 years ago. We were aiming for 2020, but now we have full commercial builds out there. Our customers’ interest is enormous (and it should be) because 5G offers such a powerful platform for the operators, for the society, for the industries. It is super important to get involved early on. To do this, you must build on what you have. You cannot build completely new networks. We have designed 5G so that 4G is actually a subset of 5G. This is done so that 5G is so much more, but the 4G fits in the 5G. We built a system that can instantly switch between 4G and 5G because they share the spectrum. So, if you have an operator that has an attractive spectrum, 4G customers, it is hard to switch completely, but if you add 5G on top of it, you cater for all your subscribers.
