Many owners of modern smartphones have noticed that some letters appear under the signal strength of the cellular network. Here you can find G, E, 3G, H, H + and LTE at different times. What do they mean and why are they constantly changing?
Instructions
Step 1
A modern smartphone is not just in the cellular network, but through it is connected to the Internet. It is about the presence of such a connection that these mysterious letters speak. Each of them means a certain data transfer rate. That is why in different parts of the city and even buildings they can change, as the maximum speed of the Internet connection changes.
Step 2
- G is the slowest second-generation network speed, 2G, to date. It is designated GPRS and is about 171.2 kbps.
- E stands for Edge GPRS. It is more than twice as high as the previous one and amounts to 474 kbps.
- 3G is the speed of the third generation network. On it, you can already comfortably watch streaming video of not the highest resolution. The speed is about 3.6 Mbps.
- H or 3G + is a third generation network. The speed is about 7-8 Mbps. The video becomes even more comfortable to watch, you can download large enough files.
- H + is an improved version of HSDPA with speeds up to 42 Mbps, in practice around 20 Mbps.
- LTE is the most modern version of fourth generation networks. For mobile objects, the speed should theoretically be about 100 Mbps.
Step 3
All the given speeds are very conditional. For each operator in your area, the speed may differ significantly from the declared one. So just be guided by the principle: the larger the letter, the higher the speed. But there are also exceptions. So, the speed H with an unstable signal may turn out to be less comfortable than the slow but reliable E. So, with an unstable connection, it may be useful to transfer the smartphone to use 2G networks. There is such an item, for example, in setting up Android smartphones.
