Difference between 2G and 3G

08 Dec 2012

First came 2G, then came 3G

Using the information in this article you should more easily choose which repeater is more suitable for you. You  can also use this useful tool which helps you choose.

2G is mainly for voice only. It can handle a little bit of data as in text messages, but that’s really it. You can forget about webpages and video.

All the old phones like the Nokia phone below operate on 2G only. For many people, this is very satisfactory as all they want is a good voice signal. data does not interest them. What’s more, the 2G signal happens to be much better at propagating into hard to reach areas like inside buildings, tunnels, basements etc..For these reasons, 2G is still used successfully on operators networks.

Then came 3G. The demand for data was increasing. Now people wanted to browse webpages and you-tube videos on their phones. Mobile phone operators had to introduce new frequencies and standards to handle the demand.


The new smart phone on the market can handle 2G and 3G now. If the 3G signal strength in a particular area is too weak, like in a basement, then the phone will switch to the more reliable 2G service. The phone can choose one service OR the other but not both at the same time. You will, at least be guaranteed a voice call. However, in many locations, even the 2G signal will be too weak and even calls will be impossible. I think we’ve all experienced this in some places.
So to recap:

Older phones: 2G only. No internet possible here.

New smart phones: 2G + 3G. As long as there is a good 3G signal in the area, webpages/ you tube is all possible. And if the 3G signal is too weak, it switches to 2G and at least calls will get through.

Frequencies in Europe for 2G, 3G and LTE:

2G Frequencies: 900Mhz and 1800Mhz (predominatly 900Mhz)

3G Frequencies: 2100Mhz

LTE Frequencies: 900Mhz and 2600Mhz(uses the old 2G Frequency)

When choosing a mobile signal repeater for your house, The are three choices.

2G repeater only (GSM900)

3G repeater only (UMTS/3G)

Dual band repeater, 2G + 3G combined. (more expensive)

    OFCOM allows the use of repeaters in the UK (but only under conditions that make them impractical for general use)

    25th October 2017
    I am an engineer working for Stelladoradus and I am going to discuss the new ruling from OFCOM about repeaters in the UK.  Stelladoradus currently sells repeaters across mainland Europe, and we are displacing the sales of cheaper Chinese repeaters in these countries. These Chinese repeaters are a nightmare for the regulators like OFCOM because they create noise [...]
