The way that we communicate has rapidly changed over the past few decades. and VoIP (Voice over Internet Protocol) have made inroads into the traditional landline phone – but they are still widely used in offices and many homes. High-speed broadband Internet connections (including fibre available directly to some homes) have nearly replaced the older, slow dial-up Internet, and today, we can’t imagine life without a constant Wi-Fi connection. This increase in technology has allowed working to be more flexible – both in terms of increased connectivity wherever we go, and new technologies give us access to files and software – no longer are we tied to a physical office.

In our businesses and homes, we often set up a wireless access point or router so that we can connect directly to our broadband connections – but this isn’t always possible. If the connection goes down, or we want to share a mobile phone’s Internet connection for a meeting or at an off-site location, we can set up a / an network, which may not be as reliable or secure. The process of connecting to a mobile phone’s data connection is called . If we connect to Wi-Fi in a public space such as a café, we call this .

These networks may not be as secure as traditional networks for example if the connection is not , or an attacker has set up a fake public network using a similar network name.   These networks may have a lower level of service – for example a poor mobile data connection will be a lot slower than a fixed broadband connection, especially if still using an older 3G network, or the is poor. Mobile coverage is still improving, and will be further enhanced through the roll out of the newer 4G and 5G technologies. The range of an ad-hoc network is likely to be very limited compared to a normal wireless access point.

Network availability isn’t universal, but as companies invest in new infrastructure, the coverage is improving, especially in areas. In these areas, slower speeds and patchy connections are possible because fewer customers means less investment in infrastructure by the providers. In , mobile coverage can also be patchy because of tall, densely packed buildings and urban surfaces disrupting signal. Walk into an old building with thick stone walls and your signal can disappear! In the world, more users may use mobile Internet because of the high cost of installing fixed-line Internet – a single can support several thousand people. In countries such as the UK, many of the mobile phone providers use their own equipment – this means that many areas are covered by more than provider (some piggyback on (use) other networks). Areas where there is no signal is called a . For example, a valley surrounded by high mountains.
