The US seems to be making all the wrong choices when it comes to 5G networking, for all the wrong reasons. Also, I’m one of those who thinks it will be YEARS before you and I have useful 5G phones or anything else.
All you have to do is look at AT&T, who did the exact same thing with 5G as they did with 4G – lie to their customers and try to fool them into thinking they already have the new technology, when they don’t. It’s cheaper to lie than it is to roll out all that new technology all across this great nation. MUCH cheaper.
I worked in the Cell Phone industry for 10 years, and one thing I learned, is the companies are dependent upon the radio frequencies they are assigned. The first generation cell phones use relatively low frequencies, which carry less data, but travel further, and penetrate walls and buildings much better.
Your ancient analog cell phone, or even the 2G digital phones, would work fine inside shopping malls, or high rise buildings, whereas your 4G or 5G phone most likely would not, without assistance. Now the US wants to use extremely HIGH frequencies, which other nations around the globe aren’t. The higher the freqency, the shorter the maximum distance it can travel (at the same wattage signal), and the worse it can penetrate walls and buildings. 60 GHz signals won’t even pass through a glass door, much less work in your living room. Unless you install 60 GHz 5G transceivers in every room in your house, that is. This is not the promise the carriers are making to us, is it?
Opinion: The US should be focusing on building 5G networks with mid-band spectrum, because it will support faster, cheaper, and more ubiquitous deployment.
