There are lots of techy terms when it comes to networks. So, to help you get your head around them, we've explained them in plain English.
- 2G and 3G
3G networks use the latest technology (3rd generation) to allow people to download and send data quickly and easily. 2G is slower (2nd generation) so isn't as good for data but it's great for calls and texts.
- 3G+ and EDGE
3G+ uses a technology called HSDPA (High Speed Download Packet Access) which increases your 3G data connection speeds even more. If you're within a 3G+ cell, and your device supports HSDPA, you'll notice a 3G+ symbol on your handset screen. Similarly, EDGE increases 2G data connection speeds.
- Base stations
Base stations, also known as "sites" or "masts", contain the transmitters that provide signals. They usually comprise a group of antennae and a cabinet to house the equipment. Base stations can be sited on top of buildings, added to existing masts or built specifically to reach particular areas or users.
- Cells
The antenna connected to a base station provides signal for a specified geographic area known as a "cell". Cells can vary greatly in size, depending on the need in that particular area. In a low population area a cell might be 5km across while in a busy city they could be just 100m wide.
- Coverage maps
Some operators refer to "population coverage" ie. the number of people their signal reaches. But that doesn't explain what the coverage is really like, where you need it. Our coverage maps give you the full picture. We show indoor coverage as well as outdoor, the types of services available and any future plans.
- Data speed
The faster your data speed (measured in megabits-per-second), the better your web browsing experience. Speed depends on a number of factors: base station capacity, quality of device, signal type/strength and location. Because speed is shared between base station users, speed will also depend on the number of other people using their phones/dongles at any one time.
- Signal/Coverage
To use your mobile device, you need a "signal" from your operator. The strength of that signal is displayed - usually in the form of bars - on your handset screen. The stronger the signal, the more bars you'll see. Signal can also be referred to as "coverage" so a coverage map displays signal strength in different areas.
