5G mmWave Facts And Fiction You Need To Know

By | November 29, 2020

5G networks are upon us and this next-generation of wireless communication is being powered by a replacement technology referred to as millimeter wave (mmWave).

As with every new technology, there are inevitable teething problems and hurdles to beat before it goes mainstream. Millimeter-wave technology has had its justifiable share of doubters within the past few years, with questions arising about its suitability over long distances, how well it can undergo walls, and albeit rain or a user’s hand might block the signal.


These issues aren’t unfounded, but most of them are figured out in recent years. MmWave technology is simply about able to make its public debut, so let’s examine the present state of those concerns. First, let’s quickly recap what millimeter wave is all about.

A Quick Primer on mmWave

MmWave and 5G are used almost synonymously, but there are key differences between the 2 . The mmWave technology is simply one a part of what future 5G networks will use. you’ll even have heard about “low band” frequencies and “sub-6GHz,” both of which can even be a part of the quality , and when combined will offer much faster data speeds to customers, among other benefits.


The term mmWave refers to a selected a part of the frequency spectrum between 24GHz and 100GHz, which have a really short wavelength. This section of the spectrum is just about unused, so mmWave technology aims to greatly increase the quantity of bandwidth available. Lower frequencies are more heavily congested with TV and radio signals, also as current 4G LTE networks, which usually sit between 800 and three ,000MHz. Another upside of this short wavelength is that it can transfer data even faster, though its transfer distance is shorter.

5G Won’t Work When it Rains

This sounds pretty damning. It’s not like 5G doesn’t add the rain in the least , but there’s some truth to the present .Much like the 2 previous points, rain within the air adds an additional level of density and thus attenuation to signals as they travel. Humidity can cause an equivalent problem. This isn’t a replacement phenomenon for 5G though. “Rain fade” is a problem for contemporary GPS and other high-frequency satellite communication systems. Granted, those operate all the answer in space, and 5G will potentially suffer issues over just many meters.


Millimeter-wave signal strength will degrade somewhat when it rains, which can first end in slightly slower speeds then potentially connection problems. what proportion it degrades will depend upon just how hard it’s raining, and other factors just like the distances from the cell tower. Rain will cause the foremost problems when connecting at the sting of a mmWave base station’s range.

mmWave Harms Your Health

We’ve covered that here, and that i won’t dignify the conspiracy theories with anything quite this — no it won’t. Of course, I’ll always welcome new thorough research that helps us understand any risks better, but currently, there’s a reputable indication of health risks.mmWave doesn’t go far enough permanently coverage.mmWave is certainly the shortest-range technology getting used for next-generation networks, but it’s not so short on be useless. Base stations will likely offer to a kilometer of directed coverage, although 500 meters (~1,500 feet) is perhaps a safer bet, after taking under consideration obstacles and foliage.


That’s obviously not an enormous area. more base stations will got to be packed closer together to hide an equivalent areas 4G networks cover now. this is often why we’re unlikely to ascertain mmWave deployed call at the countryside or small towns. it’ll probably only be utilized in urban centers, where it covers the utmost number of consumers during a small space.
