I regret buying iPhone 12 with 5g "only", maybe

Beware of excellent misunderstanding.

At the iPhone announcement event, Tim Cook CEO was 5G.Start up to Verizon's Hans Best Best Bag CEO and fast!Low delay!game!movie!I was doing it.

5G smartphone inexperienced person may buy immediately, but inexperienced persons are 4Gbps (4 gigabit/second), but if you do not hold a smartphone in the sky right below the 5G base station, you will definitely be stuffy.It was Hiyahiya inner heart.

At present, there are many areas in the United States and South Korea, which are 5G slower than 4G.

4Gbps is hardly grasped in the United States

"Spread the 5G network in 1800 cities in the United States and deliver 5G to more than 200 million on the new iPhone." Verizon Best Best Best Best Best Best Best Best Best Best Best Best Best Best Best CEO also descends up to 4Gbps at the same time as the "ideal condition".It was appealing, but Verizon's 5G is mainly a sub 6 (low frequency band less than 6GHz), so it is a speed (several hundred Mbps) that is much closer to 4G.The area where you can use the 5G network of the ultra -wide band (MMWave) that demonstrated at the event is a part of a small part of the cities.

Gartner senior analyst TUONG NGUYEN also said in an email.

It may be a bit confusing, but 5G has two LTE and NR.

・ LTE of wide coverage sub 6 (less than 6GHz)

・ Small, explosive high -frequency band 5G NR (New Radio: New wireless technology)

Sub 6 is a frequency band that is already used in 4G LTE, so adding 5G here is like installing an update app and turning on the switch.The career can be launched 5g with a little hassle, but you can not expect a gigabit -level explosive speed performance like NR.

According to the investigators OpenSignal, the average 52 Mbps in the United States is 52Mbps, 28 in the United States..South Korea (336 (336) is faster than 9Mbps.1Mbps) and Saudi Arabia (377.2Mbps) is quite delayed.South Korea and Saudi Arabia are based on the middle frequency band, and only T-Mobile uses it in the United States.Other careers need a successful bid at the federal telecommunications committee auction, and the next auction will not be held until December.

I talked to Vida ILDEREM of Intel Lab VP about System REBOOT, but 5G was still the dawn.This year is the third year of 5G communication operation.It is said that the next -generation communication takes about 10 years for the peak performance to reach.

It is essential to add base stations to realize 5g of millimeters of millimeters promoted by Verizon and AT & T.Since it is not possible to fly from a distance like 4G, it is necessary to install a 5g small cell (small base station) everywhere in the city (this is an urban legend of health damage that "the corona spreads with 5G" spreads.There was a story that the workers were very annoying ...).In addition, 5G of millimeters cannot pass through the wall of the building, so it is explosive but can only be grasped outdoors.In other words, the real 5G communication network does not reach with a millimeter wave alone.

Even if radio waves arrive at an explosive speed of 5g, the battery will decrease at the explosion speed, which may cause overheating.When I tested a 5G network based on millimeters, my smartphone was hot as soon as the 5G signal was displayed.Moreover, 4Gbps is never detected and does not reach 2Gbps.It was fast to download the whole season of TV and watch it offline, but it was not a difference that changed my life.

"AR, VR, games, and 5G utilization scenes have been said in various ways, but it has not been fruitful as one," said nguyen earlier.Well, even if you get a 5G coverage, you will wonder how much the iPhone usage environment is. "I can't say anything until I get it.

The situation in which Android is also placed is the same, but even if you look at the latest report of PC Magazine, which visits 26 cities in the United States and examines 5G connection performance, even the only country that supports the iPhone millimeter waves even in the United States.The current situation is not enough.

That said.The Verge also says, "I often say that if you park and use a car right next to the VERIZON base antenna, it will not be the speed of 5g millimeters, but this is not a joke."

Japanese iPhone is 5G compatible

The 5G in Japan is also spreading from Sub 6 at the beginning, and the full -scale spread of ultra -high -speed mobile communication that exceeds Gigabit is still in full swing.In any case, the new iPhone has been forgotten than the United States, so outside the United States, we have to talk about 5G in Sub 6.

I don't think anyone cares about the frequency when buying a smartphone, but for 5G, the name of the carrier and the regional difference are severe, and it is quite complicated.In the United States, AT & T called 4G LTE 5G as "5GE" and became a problem.In a similar situation in Japan, NTT DOCOMO has been warning on a good misunderstanding.

Even though I bought a 5G smartphone, it is sad when I say "It is not different as 4G!" "Only 4G LTE antenna pit is displayed!"maybe.Even if the spread of the 5G version of the 5G version of the low, medium and high frequency bands in the storm of complaints accelerates, it is not a change that occurs overnight.
