5G stirs up tempers.\u00a0According to one it is the egg of Columbus, the other is afraid that it will make him sick.\u00a0Time to list all the sense and nonsense about 5G. Major internet providers already advertise with it. However, there is also opposition.\u00a0The mildest of opponents think we won't need it, but the fiercest resistance comes from those who fear the introduction of 5G is planned with the Covid-19 outbreak. According to Californian professor Earl McCune, who himself works in Silicon Valley in California and as a professor specialized in sustainable, wireless, communication systems at Delft University of Technology, to have him assess the different views on 5G. 5G is said to be carcinogenic and disease-causing \u201cIt is a technology that has nothing to do with the biology of our body. All equipment will always have some effect on our functioning at any level.\u00a0But to make it very clear: 5G is not a living organism that can attack other organisms, such as human ones.\u00a0It's technology.\u00a0In my view, that you can get cancer or other diseases from 5G is really nonsense. \u201d 5G is linked to the corona outbreak \u201cThe development of 5G has been going on for some time, just as we have been working on the development from 1G to 4G.\u00a0To streamline the implementation of 5G with the outbreak of an infectious disease is impracticable, even if in an unlikely case it would have been desirable.\u00a0It may be the case that now, more than ever, we are dependent on fast connections and that the call for 5G may be more urgent because of this.\u00a0Not complete nonsense. \u201d "98% TO 99% OF 4G TECHNOLOGY IS EXACTLY THE SAME AS 5G" 5G is a completely new technology \u201cAnother big misunderstanding.\u00a098% to 99% of 5G's technology is exactly the same as 4G's.\u00a0That is technology that we have been working with for a while and that we therefore trust.\u00a0A characteristic feature is the use of the millimeter wavelength, which is what is different about 5G.\u00a0That way your phone can communicate directly and specifically with another phone.\u00a0With 4G, your phone actually communicates with everything and everyone around it, within a radius of 2 to 3 km2.\u00a0That is a waste of all that energy.\u00a0All our 4G phones are heating up the grass, I call that.\u00a0That's why it's slower than 5G. \u201d 5G further endangers our privacy \u201cCan't anyone be so naive?\u00a0I thought this was well known by now.\u00a0Our emails are really just publications.\u00a0Officially it is said that they are not public, but \u201c\u00a0discoverable\u00a0\u201d.\u00a0Right.\u00a0Everything you send is of course stored somewhere and retrievable.\u00a0Then you might have to get a pre-paid phone.\u00a0And then pay them in cash.\u00a0That might be the only way to communicate digitally in a somewhat untraceable way.\u00a0We lost our freedom 10 to 15 years ago.\u00a0And everyone who uses apps like WhatsApp, Google and Facebook hopefully knows that.\u00a0Get over it, I would say.\u00a0That really has nothing to do with 4G or 5G.\u00a0In fact, the added component to 5G, the millimeter wavelength, has proven to be safe to use in sensitive segments of politics and for military purposes, precisely because of that targeted communication between mobile phones instead of a wide radius. \u201d 5G is more efficient than 4G \u201cThat depends on what you mean by efficient.\u00a0It's faster and more focused.\u00a0You need much, much less energy with 5G.\u00a0In that sense it is very efficient.\u00a0There is only one disadvantage and that is immediately a big disadvantage.\u00a0It comes with a hefty price tag.\u00a0The costs of connecting our entire mobile network to it are enormous.\u00a0Providers will try that, but without passing on those costs to someone, no business model is possible.\u00a0It cannot be profitable.\u00a0Who will pay the costs?\u00a0Will the subscriptions become more expensive?\u00a0I do want 5G, but I don't feel like paying a lot of money for it.\u00a0And the vast majority of people don't.\u00a0That is why we need a new technology that does offer the advantages of targeted, fast and energy-efficient communication, without the economic disadvantages.\u00a0That's possible,\u00a0we have the physical principles in house and with those principles we can develop and build the technology.\u00a0That's what we're working on at TU Delft, but that's what I do here in Silicon Valley in my own company.\u00a0I expect that we will be able to come up with an efficient 5G variant within a few years. \u201d "I CAN SEE 6G BEING DEVELOPED WITHIN TEN YEARS" 5G is not a real keeper \u201cI don't see how any G's ever going to be, as the G's haven't been until now.\u00a0So indeed, people will want to improve 5G, if only because it is indeed not cost-efficient.\u00a0People will not want to sell those improvements as 5G.\u00a0That has to be another denominator, of course, one that cannot be associated with what we then see as the disadvantages of 5G.\u00a0That will automatically become 6G and yes, I see that being developed within 10 years.\u00a0In fact, in 15 years' time we will be walking with a mobile that works on solar energy.\u00a0This technology is of course also available now, but because 4G is so little targeted and therefore requires a lot of energy, you would walk around on your mobile with an appendix of one meter of solar panels.\u00a0Not really practical. No more hassle with chargers, putting your phone in the windowsill now and then and then being able to stay online everywhere nice and cheap, super fast and safe.\u00a0We look forward to it, but for now we are careful with our chargers as we carefully take the first steps with 5G.
