Publikováno v: 5G World Forum

One of the aims of beyond 5G (B5G) wireless communication networks is to increase the data rates, while keeping lower latency and high energy efficiency. To achieve this, massive multiple-input-multiple-output (mMIMO) systems combined with two dimens

The increased carrier bandwidth and the number of antenna elements expected in 5G networks require a redesign of the traditional IP-based backhaul and CPRI-based fronthaul interfaces used in 4G networks. We envision future mobile networks to encompas

To meet the requirements of 5G mobile networks, several radio access technologies, such as millimeter wave communications and massive MIMO, are being proposed. In addition, cloud radio access network (C-RAN) architectures are considered instrumental
