Introduction to Wi-Fi Hotspots

Wi-Fi hotspots are locations that offer wireless internet access to members of the public. Examples of locations that typically offer this include cafés, restaurants, airports, train stations, hotels, libraries and schools and universities.

How can the Public Access Wi-Fi Networks?

Members of the public can access the network at a Wi-Fi hotspot through Wi-Fi enabled devises including laptops, mobile phones and tablets. This means people can use their mobile devices to access the internet while away from their home or place of work.

How Does it Actually Work?

Put simply, these hotspots use radio waves to transmit data to and from the internet. Wireless routers are used to transmit data to and from wireless enabled computers. This works in the same way as a wireless network many use at home or in offices.

How Much Does it Cost?

The cost of using a Wi-Fi hotspot varies from location to location. Some are free to use and are used as marketing ploys. For example, cafés might offer free Wi-Fi in an attempt to entice customers through their doors. Hotels might do the same to encourage visitors to stay with them instead of with a competitor. Often, though, there is a charge to access the network and the price of this can vary greatly.

What are the Benefits?

You can’t quite access the internet from anywhere, but the main benefit is that internet use is often within relatively easy reach. If you are in a city centre and suddenly need to send an email or visit a website then you are likely to find somewhere with a Wi-Fi hotspot, such as a café, where you can then do what you need to. This can be particularly useful to those having to access the internet for business purposes while on the move. The internet is becoming more widely used for business and this means Wi-Fi hotspots can be useful. If someone has a lengthy train journey, for example, and the train has Wi-Fi access then they may be able to use the time to connect to the internet and work. This can turn what might otherwise be an unproductive journey into a productive one.

What are the Downsides?

The main downside is the potential for security concerns. Compared to when using wired networks, it is relatively simple for someone who knows what they are doing to hack into computers connecting to the internet wirelessly. Many don’t realise the security concerns and therefore do not protect against them.

How can Security Issues be Prevented?

One way of limiting security problems is to use common sense. People shouldn’t deal with personal and confidential information online when using a hotspot unless they are sure they are protected. This includes things such as dealing with important passwords and accessing online bank accounts. As well as the usual internet security measures (anti-virus software and firewalls) it is wise to utilise a VPN (virtual private network). A VPN will create a secure tunnel between a computer and the internet meaning others cannot interpret data.
