Apple's mobile phone is disconnected

The reason why WiFi will be disconnected after frequency locking is because iPhone6 is set to automatically disconnect WiFi when sleeping. The solution is as follows:

1. Open the phone and click the settings icon.

2. Select the WiFi option bar.

3. Click the option in the upper right corner.

4. Then select the advanced options bar.

5. Click to keep the WiFi connection bar dormant.

6. Select Always at this time. At this time, WiFi will always be connected, and the mobile phone can download things in the background.

Base station handover:

The reason why mobile phones can make phone calls and send short messages online is because all our communities are provided with signals by a "base station", which you can understand as a signal transmission center. Each base station has a certain coverage area, which is geometrically like a honeycomb. If you happen to be on the edge of two cells, and the signals of the two base stations are almost the same, there will be a phenomenon called "ping-pong handover". When the cell phone signal switches back and forth between different cells, the signal will be very unstable, and it will be repeatedly disconnected and reconnected, sometimes left and sometimes right. At this time, don't say that the game was cut off. It is a problem to make a smooth phone call.

Interference:

Interference can be divided into external interference and internal interference. External interference simply means that there are many 2G/3G/4G mobile devices near you, or the interference of the same channel affects the stability of your signal. When the interference is very strong, such as shielding the instrument, then there is no signal at all.

Load balancing:

If there is one more person and one less person in two communities, it is high load and low load. Then the base station will use an algorithm to "move" the signals of people in high-load cells to low-load stations. At that time, you were forced to switch, and the effect of switching was a short disconnection.

Therefore, more than 90% of the dropped calls we encounter are not caused by the mobile phone itself, unless your mobile phone uses the MediaTek core and the router uses the Qualcomm core. When choosing a router, it's best to ask what chip is used first to avoid a bad experience due to incompatibility.
