5G is not going to measure up to the hype and will not answer our lack of competition, innovation, high-speed, reliable, and cost-effective broadband options…
This post is a “deep drive” into what has come before, the technology and science, and the application of 5G (in the US). A need was seen after talking with numerous elected officials to provide more comprehensive information on what 5G is and is not for McHenry County, Illinois and other communities.

5G is the next generation, fifth generation, in cellular network technology. 5G follows 4G, 3G, 2G and 1G and their respective associated technologies.
5G is an early technology, still in the planning and testing stages, but is a compilation of many different technologies. Companies and industry groups are working together to figure out exactly what it will be.
5G is distinct from earlier technologies, that 5G is going to offer additional frequencies (bandwidth) and more advanced technologies. Such frequencies in the <6 GHz range and >24 GHz range are going to be offered, which is going to provide much more bandwidth throughput, but with shorter ranges and additional interference issues. 5G is going to include such technologies like Millimeter Waves, Small Cells, Massive MIMO, Beamforming, and Full Duplex.
5G spectrum is going to consist of three different types of bands, Low-bands of below 1 GHz, Mid-bands between 1 GHz and 6 GHz, and High-bands of higher than 24 GHz. In essence, longer (low frequency) wavelengths travel longer distances and go through things like buildings, trees, and water more effectively, but support slower data speeds. High frequency wavelengths travel shorter distances, but do not go through buildings, trees, and water effectively, but the data speeds can be much faster.
5G is not a finalized standard yet and will not be until late 2020, even if it does finalize, there is a chance it’ll splinter into different standards as 4G has.
5G has already turned out to not be 5G, like in the case with AT&T’s 5GE. Most of what you see being advertised is hype and should be viewed with skepticism going forward. While some cellular companies are saying they have 5G, those claims, are arguably, inaccurate. This emerging technology is still being developed and implementation is still years away.
One of the biggest challenges for the cellular providers is the ability to offer the full capability of 5G everywhere. 5G requires fiber and millions of miles will have to be built along to connect the respective 5G antennas and towers. The respective business case for laying, what is essentially, fiber to the curb, is not very profitable and will unlikely occur without some significant strategy changes in our communities across America.
5G is not going to measure up to the hype and will not answer our lack of competition, innovation, high-speed, reliable, and cost-effective broadband options due to a number of limitations ranging from lack of fiber-optics everywhere, interference and distance issues, profitability, spectrum ownership, and more. Alternatively 5G will, very likely, be a continuation of the current status-quo. Without implementing forward-thinking strategy and infrastructure that is focused on the needs of the community, arguably, nothing is going to change.
5G will be a very useful evolution in wireless in that it will provide faster, lower latency networks that are more easily managed (in large part due to virtualization technology). But 5G is not some mystical fucking panacea.

These videos are very helpful to distill very complex topics to very simplistic ways, but are not necessary to understand 5G and the conclusion.
