Our first 56 capable radio is a showcase of cost efficient evolution to 5G: Christian Hedelin, ricsson

摘要

Christian Hedelin: If we talk from use case point of view, it can be divided in terms of supporting two different use case clusters. The first one is to have a continuous improvement of the mobile broadband services and that includes being able to support higher data rate, video resolution, high bandwidth requirements for smart phones and other devices. With 5G we have opportunity of using the wireless network as a last mile access. So that is one use case cluster. Basically, continue to build the existing mobile networks to provide better broadband services. The second use case is massive machine type communications, and that is what we are looking at. There are two types of machine-to-machine communication. First is, massive machine type communication, which is a large sensor network that enables you to deploy sensors for applications like utility, agriculture etc. That is also one area, which will evolve a lot. Secondly, we also have mission critical machine type communication, which is large sensor network for smart grids, fleet management, tracking of logistics, etc. The third use case is critical machine type communications that require higher reliability and latency. These are needed for industrial applications, where we have everything from autonomous vehicle to industrial application and process control. You would like to improve the productivity and things that are very mission critical. There you would need to have high reliability, security and low latency. What we foresee is that we will have 3G and 4G network, and we will add on 5G capability, so there is a network evolution towards 5G. And we are investing a lot of money in this. We are implementing 5G like capabilities into the 4G network also. So, basically we have more than doubled the investment in 5G product development and more than 20% on the radio side right now.
