6G Wireless Systems: Vision, Requirements, Challenges, Insights, and Opportunities
Mobile communications have been undergoing a generational change every ten
years or so. However, the time difference between the so-called "G's" is also
decreasing. While fifth-generation (5G) systems are becoming a commercial
reality, there is already significant interest in systems beyond 5G, which we
refer to as the sixth-generation (6G) of wireless systems. In contrast to the
already published papers on the topic, we take a top-down approach to 6G. We
present a holistic discussion of 6G systems beginning with lifestyle and
societal changes driving the need for next generation networks. This is
followed by a discussion into the technical requirements needed to enable 6G
applications, based on which we dissect key challenges, as well as
possibilities for practically realizable system solutions across all layers of
the Open Systems Interconnection stack. Since many of the 6G applications will
need access to an order-of-magnitude more spectrum, utilization of frequencies
between 100 GHz and 1 THz becomes of paramount importance. As such, the 6G
eco-system will feature a diverse range of frequency bands, ranging from below
6 GHz up to 1 THz. We comprehensively characterize the limitations that must be
overcome to realize working systems in these bands; and provide a unique
perspective on the physical, as well as higher layer challenges relating to the
design of next generation core networks, new modulation and coding methods,
novel multiple access techniques, antenna arrays, wave propagation,
radio-frequency transceiver design, as well as real-time signal processing. We
rigorously discuss the fundamental changes required in the core networks of the
future that serves as a major source of latency for time-sensitive
applications. While evaluating the strengths and weaknesses of key 6G
technologies, we differentiate what may be achievable over the next decade,
relative to what is possible.Comment: Accepted for Publication into the Proceedings of the IEEE; 32 pages,

5G Mobile Phone Network Introduction in Colombia
This research received support from the AUIP (Iberoamerican University Association for
Postgraduate Studies).The authors would like to thank the following members of Ericsson and Nokia
Company for their valuable technological support in relation to the deployment of 5G networks in
Colombia and Latin America. To Ericsson Company: Fabian Monge, Head of Networks & Managed

Director & Business Development Colombia—Nokia.The deployment of the 5G mobile network is currently booming, offering commercially
available services that improve network performance metrics by minimizing network latency in
countries such as the USA, China, and Korea. However, many countries around the world are still in
the pilot phase promoted and regulated by government agencies. This is the case in Colombia, where
the assignment of the first 5G band is planned for the third quarter of 2021. By analyzing the results
of the pilot phase and the roadmap of the Colombian Ministry of Information and Communication
Technologies (MinTIC), we can determine the main issues, which contribute to the deployment of
5G mobile technology as well as the plans to achieve a 5G stand-alone network from 4G networks.
This is applicable to other countries in Latin America and the world. Then, our objective is to
synthesize and share the most important concepts of 5G mobile technology such as the MIMO
(multiple input/multiple output) antenna, RAN (Radio Access Network), C-RAN (Centralised-RAN),
and frequency bands, and evaluate the current stage of its introduction in Colombia.AUIP (Iberoamerican University Association for
