Theresa has been hearing about 5G and recently found out they're getting a new cell tower in her neighborhood. Is living near a cell tower safe? Leo says absolutely, there's no real issue with radiation: it's a myth. It's also really small, and the energy of radiation decreases exponentially as it gets farther away from the tower. So there's no need to worry. But the big challenge of 5G is that it requires more towers. The real evidence is, that it's harmless. Think about how often you hold a cellphone to your head: there's simply not enough energy to do any damage.
Samsung announced the Galaxy Note 10 this week. And it's huge. It's "notch" is much smaller, now more of a dot, and the headphone jack is officially missing. So Samsung has quietly removed any videos from their YouTube channels mocking Apple for the same thing. They say it gives them more room for a larger battery. Also missing is the Bixby button, which is officially dead. Price for the Note 10 - $1200. The 5G version is another $200, but Leo says don't bother. 5G isn't available everywhere yet, and it will drain your battery much faster than LTE. Right now, 5G is nothing but hype.
Mike has heard that 5G is going to be bad for our health, as it "assaults" our internal organs. Is 5G safe? Leo says that you would have to have a lot of exposure to that energy and be very close for a long time to do damage. As the energy dissipates, it does very rapidly when the distance expands to just a few feet. Waves coming off a 5G tower just aren't that risky. It was the same hysteria that came with cell phones in the first place. Also, most people don't have 5G capable phones and won't for at least a year.
Taylor hears that 5G is so limited in range, that there will be more towers and connections. Will that be harmful to people? Rich says no, but it's likely going to replace everything from home internet connection to free public wifi. But how unsightly will it be with all those towers
When will Google Duplex be able to make restaurant reservations? Rich says he just recently tried it out and it works in 43 different states.
AT&T has launched its 5G service in 17 cities around the country, but Rich says good luck trying to use it. First, you can't find a map of 5G coverage to see where it's available, plus you need a $500 hotspot device to use it if you do. Also, 5G doesn't travel very far, requiring even more towers.
Meanwhile, Verizon has launched in Chicago and Minneapolis for everyone, but in very small areas. Rich says that while 5G is the future, it's just not the future now.
Richard read an article about students in San Jose, who are hanging out under light poles because of something called LiFi? You can get over 225GB doing so, but it's limited to where the light can transmit. Leo says that LiFi has potential since light poles can double as access point stations for public Wi-Fi. But with LiFi, it uses light to transmit internet bandwidth.
Greg wants to know if 5G Home Internet is a game changer. Rich says that Verizon is testing 5G Home Internet in five cities around the country. 300/1000 down for $50. Sounds good, but that's ideal bandwidth. Is it a game changer? Well, only if it's available where you live. And 5G requires a lot more antennas, every few hundred feet. So it'll be awhile before it's widespread and Rich doesn't see it happening any time soon. If it's available, sign up.
