Did Apple only update 5G-A in China for iOS 18.4 this time?

by Poster Apr 1, 2025 95
It's very strange. I haven't seen people discuss the 5G-A (5.5 G) of the iOS 18.4 update this time, such as reddit/youtube. The English video didn't mention it, and Apple's update instructions didn't write. It seems that only Chinese users are discussing the 5G-A signal? Is this an update only for China? Why don't we see any foreigners discussing it, or do we say that 5G-A has already been popularized abroad, and we are just blinded? Can any overseas students confirm it? Why do you feel that this matter is only discussed in Jane?

    I didn't see China Unicom A after the upgrade yesterday. I just remembered to switch the secondary card and it really moved a... China Unicom in Beijing's Second Ring Road often has no signal when walking, as if it was blocked. It takes a while to enter the subway theater. Ready to cut the secondary card at any time...

    Apple's connection with China Unicom is simply out of touch

    @ Anonymous1433 # 77 I don't need to activate China Unicom, the actual measurement is 300m, and China Mobile does not display

    I asked Beijing Mobile and found that 5G-A requires a separate package charge. I'm crazy about money. It's time to consider number portability.

    What is the oldest iPhone version that supports 5GA?

    Haven't you seen a foreign broadcast? American 5g is simply bullshit

    @ Anonymous2041 Silly boy, I used to explain it for them like this, but then I thought it was wrong. Can you understand what I said? When 4G was first rolled out, I ran the most basic 4G to 900mpbs or even 1G at any time after 11 p.m., which means that the technical bandwidth of 4G is at least 800mpbs, right? Then, with 5G, I often can only have 1-20mpbs for 4G, and only 1-200mpbs for 5G; But at this time, if you change to 5Ga, you can actually have 4-500mpbs, and even some business districts have 900-1G What does that mean? Think for yourself? It shows that the reduction in mobile phone network speed is not due to the reduction in shared bandwidth caused by more people using the same bandwidth, but artificially through packages (don't mind 4G, 5G and 5Ga, the first example has proved as we have that 4G can run Full 1Gbps) perform Qos to slow down to ensure that they have more bandwidth and can sell more expensive packages, that's all What is the most obvious example of that? If it's shared bandwidth, because of work, I often take a break from 3-4 o'clock to 4-5 o'clock in the middle of the night. At that time, I don't think there are many people competing with me for 5G bandwidth at the same base station? As a result, I can only run 1-200mpbs internet speed In China, there is no shortage of merchants who speculate with the worst malice, and there are almost no exceptions (having said that, at present, if you see a pure domestic conscience, you will come from Fat Donglai?)

    Shanghai Unicom 5Ga is only more than 200 in most places. When it falls back to 4G, it seems that there is a bit of a bug and the network will be disconnected, and it needs to be reconnected in airplane mode many times in a day.. The overall domestic base station handover experience is still very poor. In addition, the base station optimization algorithm also has big problems. Deliberately bullying devices with low transmission power such as the iPhone does not meet the original intention of the optimization algorithm

    @ Anonymous457 Is it possible that it's just you slow? I can get to 1700 + MB as quickly as possible. The slow ones also have 300 + megabytes? Shanghai Unicom

    @ Anonymous5517 The 5G CPE consumes about the same power as a router.

    @ Anonymous2722 # 89 If I remember correctly, the highest deployment of 4G in China is cat9. FDD is 450mbps and TDD is 330mbps. Most base stations are cat4 and 6 The most basic 4G, if I remember correctly, is CAT4, 150/100 mbps I have always been a mobile card. The highest speed tested for 4G in 2017 was only 80mbps. I tested the 4G mode a few days ago and it still had 60mbps. For 5G, I used too much force at first. The base stations are all 64T64R and 16-channel mimo. So in 2020, any test will have 1000mbps. In addition, when there are few people in the middle of the night, you can have 1000mbps without 5GA. But with 5GA it can run to full 1000mbps during the day. Why 1000mbps, because my card can only run to 1000mbps

    @ Anonymous2722 You must have remembered it wrong, or the speed measurement software is inaccurate. The theoretical bandwidth of lte fdd + tdd five-carrier aggregation is only 1000Mbps. What's more, this kind of aggregation has never been opened in China. The three-carrier aggregation has been opened for several months, and the speed measurement is more than 400 Mbps, and it was shut down nationwide because of the overall instability of the network.
