5G is primarily deployed using the 3.5 Gigahertz (GHz) bands, which is very likely to suffer in indoor settings because outside-in typically does not provide adequate indoor coverage in the mid and high bands. Therefore, in-buildings wireless solutions are becoming more important for consumer and enterprise 5G markets. The new generation of use cases beyond 5G require even higher levels of performance and Quality of Service (QoS), so new technologies are needed to be developed to tailor to the need of every specific use case. Many new technologies are now being developed to fill this gap. The distributed Massive Multiple Input, Multiple Output (mMIMO) solution was developed by Huawei to boost indoor experience and a network operator’s competitiveness, and is expected to be implemented on a larger scale for 5.5G. pCell is commercialized by Artemis with a focus on improving private network performance. In the longer term, Radio Information Systems (RISs) and radio stripes are viewed as real value-added technologies for 6G systems.
