"G" "E" "H" "T" signal perfect explanation

 Mobile users:
The Network Diagram of the mobile phone is marked with the three types: "g, E, h
G: The peak value of GPRS's transmission rate theory is 114 kbps, which is an early wireless network transmission method.
E: edge has a transmission rate of 384 kbps at the peak, and is now a mainstream wireless network transmission mode.
T: Full name: TD-SCDMA technology is in its infancy, the current version is divided into R4/R5/R6/R7. The theoretical value of R7 can reach the peak download speed of 12 Mb. However, the current version is R4. The theoretical download value is 378.2kb/s, which is relatively small. However, after all, it is subject to the proprietary intellectual property rights of China, so it is still supported a lot.
When your phone's signal is unstable, it will switch between these three frequencies. Ensure your basic phone call requirements.
Unicom users:
There are only two types of connected users: "G" and "H"
G does not need to be said. It is the same as mobile, but because of the small number of base stations, the 2G network of China Unicom is slow...
H, so let's talk a little more: I mentioned the theoretical download speed. Actually, when I was using it, it was the same as the 1 mbps bandwidth used in our house, if it is better, the speed can reach 2 MB. Likewise, it is a relatively high cost of electricity.
