Our smart network

3G networks use the latest technology (3rd generation) to allow people to download and send data quickly and easily. 2G (2nd generation) is more suited to calls and texts, but also fine for mobile email and PXTs. We have a 3G/2G layered network design which means that if our 3G network should ever experience a hiccup, your mobile will switch to our 2G network, where there is available coverage, so you can keep calling and texting without interruption.

3G+ uses a technology called HSPA (High Speed Packet Access) which increases your 3G data connection speeds even more. If you have sufficient 3G signal, and your device supports HSPA, you’ll notice a 3G+ symbol on your handset screen.

Base stations, also known “cell sites”, “masts” or “towers”, contain the transmitters and receivers that provide signals to your mobile phone or device. 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 customers.

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 and population density in that particular area. In a low population area a cell might cover a 30km radius while in a busy city that distance could be just 100m.

To use your mobile device, you need a radio “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.

The faster your data speed (measured in megabits-per-second), the better your web browsing experience. Speed depends on a number of factors, including base station capacity, capability of device, signal type and strength and location. Because speed is shared between base station users, speed will also depend on the number of other people using their phones or other devices at any one time.

While your web browsing experience is improved with increased data speed, it is also affected by a number of other factors. One of the biggest influences is called “latency” which is a measure of the time it takes for a data packet to travel from your computer to the internet and for the response to return. Latency is measured in milliseconds using a “ping” test.

Other important factors that determine the speed is the degree of data compression used. The maker of Blackberry, Research In Motion, apply a large degree of compression which helps make the Blackberry a very efficient device and able to send and receive large emails very quickly. Vodafone also improves the speed by compressing the data for all devices.
