Why does the phone in Beeline constantly switch network modes?

Question

Beeline

Help solve the problem:
The phone (4th Nexus, android 4.3), constantly switches network modes - 3G, H, H +, E, and sometimes even G shows - at the same place in the office. Accordingly, the mobile Internet does not work normally - the connection is constantly interrupted, or it is completely impossible to do anything on the network.
It helps to turn on / off the mobile Internet in the settings, but not for long - after some time the story repeats itself. The problem is in both 3G and 2G only modes.
Can something be done about it? Change OPSOS - the edge.
Thank you.

Answer 1

Switching between communication standards is a normal mode of mobile network operation. There are a lot of reasons for switching, the main ones are:
- changing the standard depending on the requested service (for example, when making a voice call you will be sent to GSM, and when downloading a file - to HSPA +
) lack of high-speed HSPA codes - will be sent to a simple 3G, etc.)
- The level of the radio signal at the location of the terminal (the fact that the device is stationary does not mean that the radio conditions remain unchanged). The better the signal - the better the service is provided: 2G-E-3G-H-H+
And constant breaks, and friezes when downloading - really most of all look like network congestion.
