I can't communicate even though the antenna is the largest!?

　The SIM -free version of "Xperia 1 II", which is used by inserting NTT DOCOMO and Y -Mobile's SIM card, has recently happened.There is a phenomenon in which communication cannot be performed at all when "5G" is displayed in an antenna pict in a specific place.

　Unlike the so -called "package clogging" of the 4G era, there is no way to flow the data.In other words, it can be called "package stop", but it has the impression that the frequency of occurrence has gradually increased since spring.

　I recorded it in a video of what would happen if a package stops.The following is an attempt to open the top page of "Mobile Watch" on Chrome.I couldn't do any data communication at all and got an error, so I re -loaded it, but the site was still not displayed.The mobile phone Watch is not falling, and the application of Twitter and Facebook has not been able to communicate.Did you see that the situation is different from clogging?

　At this time, if I left it for a while, I started to be connected.In other cases, the data communication was sometimes flowing on and off in flight mode.However, if you are looking at the site, you can deal calmly, but if you suddenly stop communicating in a place where you have to communicate in a hurry, you will be quite impatient.In the case of the author, the au pay, which was launched at a convenience store, was impatient in front of the cash register.At night, there were few customers, so I got it on and off in flight mode, but if it was crowded, I might have left the cash register.

　After experiencing a package stop, I got some trends.First, the place where the occurrence occurs is almost the same.The place where the package stops, including the area near the home, the commuting route of the office, and the area near the office, is almost the same.It is troublesome that it does not always happen when you are in that place, but this phenomenon occurs at least once a day because it includes places that go back and forth on a daily basis.At first, I thought that the SIM -free terminal was the cause, so I asked my acquaintance and tried to find out the voices of Twitter, but it seems that it occurred on docomo terminals and iPhone.At least it doesn't seem to be due to a specific device.

　At the first day of DOCOMO's presentation, there were also questions asking if this trouble was grasped.According to DOCOMO, "we recognize that the possibility of (stopping the package), including what you have pointed out due to the characteristics of propagation, is not zero."On the other hand, he said, "There may not be enough to recognize individual events."Considering the frequency of occurrence, it may be that we are trying to investigate some causes.

　What is common in places where the package is stopped is that the 5G radio waves are infinitely weak or the radio waves are originally not included.For example, the following is the screen of the application when a package occurs.Perhaps because he was away from the base station, the electric field strength was very weak and the communication was severe for communication.The surrounding area can be communicated without any problems, so it should be separated from 5G, but if you look at the operation of the terminal, you can see that you have tried many times and failed.

　In general, mobile phones are more likely to be affected by the distance that emits radio waves from the terminal rather than the descending communication receiving radio waves from the base station.Unlike base stations, which are easy to increase output, there is a limit to transmitting from the terminal side.In this case, it seemed that he was trying to continue communicating on the descent without releasing the 5G radio wave without releasing the 5G radio wave.Unlike 4G covered on the surface, 5G is still a spot.It may be one of the reasons for stopping a package because there are many cell edges (the boundary of the area).

　The above is just a guess, but if it hits, it may take time to complete the fine tuning and further expanding the area on the base station side, and it may take time to complete a complete solution.If 5G is turned off on the terminal side, it will be stable, but docomo's 5G is very fast if it is connected properly just because it sings "instantaneous speed".It is annoying because there is also the merit of turning on 5G.With the launch of AHAMO's service, we hope that the 5G users are expanding rapidly, so that the problem will be solved as soon as possible.

[Apology and correction 2021/05/27 8:12] When the article first appeared, there was a part that said, "If you turn off 4G, it will be stable."To be correct, "if 5G is turned off, it will be stable."We apologize and correct.
