Does the current technologies capable of providing affordable site equipment necessary to deploy 5G network at 20-90 GHz for mobile access?
at what price ?
We all know that 5G should appear at 2020.
Dear Naser,
welcome,
The best way to follow the state of the art of certain technology is to survey its review papers. In the this link you will find a useful review about the state of the art of using mm wave in 5G mobile networks:https://arxiv.org/pdf/1708.02557.pdf
One of the most suitable applications is to use mm wave in backhaul link between the base stations and the core of the network.
From the electronic side, please see the attached mm wave technology report: https://www.highfrequencyelectronics.com/May09/HFE0509_TechRept.pdf
I think the two papers will give you an idea about state of the art of mm-wave communications and electronics.
Best wishes
Hi very interesting question. So far what I know is that the first deployment will be at sub 6 GHz.
Good Question from Dr Naser Al-Falahy and good answer from Dr Abdelhalim abdelnaby Zekry

Hi, there is already one live deployment at mmWave from Verizon, which was actually the first globally and was launched in June 2018 at 28 GHz. Other USA operators have also plans to launch 39 GHz in the next couple of months. Vendors have already radio equipment commercially available in mmWave, e.g. Ericsson AIR 5121 (28 GHz) and AIR 5331 (39 GHz). This equipment is apparently more expensive than the corresponding for low frequency, but in any case this is an issue of cost-benefit analysis for the operators.
Dear Mr Al-Falahy,
For the first question, according to a survey that I have done recently, the answer is:
"In the initial phase, the principal worldwide spectrum options for 5G are at 3.3–4.9 GHz, 24–28 GHz, and 39 GHz."
By the end of the year, the full set of certification test suites for 5G chipsets, modules and modems will be complete by The Global Certification Forum (GCF). GCF is already collaborating with the mobile industry to prioritize work items supporting the functionality of initial 5G devices aligned with the 3GPP roadmap (which includes the millimeter wave communication in the first phase), as well as financial support for the development of 5G.
I hope that I gave you an informative answer.
Sincerely,
Currently, the 26 GHz and/or 28 GHz bands have the most international support in this range. A key focus at the ITU World Radiocommunication Conference in the end of this year 2019 (WRC-19) will be on establishing international agreement on 5G bands above 24 GHz.
The first phase of 5G deployment is already in the field.
That's mean only after adoption of Agenda Item 1.13 of WRC -19 (I hope!) in the end of November.
