Three levels of details in mmWaves propagation modeling

2020-12-14
How to predict the power received in the given area when mmWaves are in use? This post describes three classes of propagation models can be addressed starting from very basic to precise ray-tracing models for mmWaves.

5G Core Summit – Cloud, Fog, Private 5G and Initial Deployments

2020-12-01
We recently took part in the 5G Core Summit by Informa and Knect365, a virtual conference, which I'd like to shed some light on. The conference's main areas included: 5G use cases and ecosystem development, network cloudification, edge clouds, and network slicing, trials and lessons learned from initial deployments, specialized use cases, private networks and practical aspects of the first implementations, evolution strategies, and alike.

3GPP Rel-17: Way forward within 5G standardization

2020-11-16
As the first two releases covering the 5G system are completed (i.e. Release-15 and Rel-16), further features and enhancements are being covered within the ongoing 3GPP Rel-17. This post discusses a subset of the features from that release, including Non-Public Networks, higher frequency ranges, Unmanned Aerial Systems, Network Slicing enhancements and alike.

5 Key Differences Between mmWave and sub-6GHz

2020-11-02
5G is the first system where frequencies higher than 6 GHz are taken into account. The motivation behind new spectrum portions is the mentioned need for offering throughput of gigabit/s and more. The game is worth playing since, in the mmWave, Gigahertz spectrum bandwidths can be applied. But one may pose the question: if the price is so exciting then why nobody used mmWaves previously in cellular systems?

Green Communication and Computing for 2030

2020-10-19
Since the UN General Assembly in 1987, sustainable development has become the aspiration of modern societies. The development of ICT, has contributed remarkably to global energy consumption, although the translation of the data traffic volume to energy use and greenhouse gas emissions is not straightforward. According to SMART2020 report, the ICT carbon footprint was supposed to increase about 3 times between 2002 and 2020. However, newer reports, corrected these predictions and showed a stabilized trend in the ICT footprint.
