Public wi-fiÌýshould be separate from anyÌýwi-fi set up for staff/churchÌýuse. This is for securityÌýreasons (particularly ifÌýchurch/staff computers areÌýstoring any data that hasÌýsafeguarding implications).

Costs depend on the monthly contract you choose with your chosenÌýÌýinternet provider but will probably be around £20 to £50 per month.

Make sure to get a contract with enough data for multiple people to use it at the same time and ensure that the wireless access point can support sufficient concurrent users (many ‘free’ access points have a very limited number of simultaneous users.)

Depending on the size ofÌýyour building, how many pillars and thick walls you have, and how farÌýyou want the free wi-fi to reach, you might also need additional accessÌýpoints, which will cost extra.

All major internet providers also offer business broadband deals which include the ability to offer advanced public wi-fi. Speak to your preferred provider about your needs and what they can offer you. The more advanced the system, the more it will cost but the more secure and scalable it will be.

You can also restrict the use of certainÌýwebsites and stop adult websites from being accessed entirely. WhenÌýchoosing an internet service provider, it’s important to shop around andÌýget quotes for their services before signing a contract.

Option 2 – buy a wi-fi hotspot

Another option is to buy a wi-fi hotspot. These can be bought online.ÌýThey work off mobile 4G coverage that people can use to connect to wi-fi.ÌýÌýThese can be bought through most tech stores and at Amazon.co.ukÌýbut you still need a contract with a mobile provider to set this up.

The cost can be anything between £15 and £50 per month, dependingÌýon how much data you want. Choose this option if you have a goodÌýmobile-phone signal inside your church building (this may not be theÌýcase within the thick walls or rural locations of some buildings.)

MostÌýcontracts with the major UK mobile companies offer a wi-fi hotspotÌýdevice for free. The downside to a hotspot is that it will have fairlyÌýlimited reach and might be too slow for what you are looking for.

Alternatively, there are companies that will set this all up for you.ÌýThe benefit of a set up like this is the option of having a customisedÌýlanding page that people are sent to once connected to your churchÌýÌýwi-fi. This can be a page on your existing website and could includeÌýguidelines on how the wi-fi in your church can be used.

You can find your local network installation specialist by contactingÌýÌýor calling 01480 213 744.

Other things to consider

How much local technical support are the church staff or volunteersÌýexpected to provide? Giving out the wi-fi password is one thing,Ìýanything more complicated than that is another thing entirely. IfÌýyou’re able to, it might be worth sending staff or volunteers on some training (online or a course) to better understand the technology.

If you are already using wi-fi for things such as sound desk control, beware of the limited availability of the 2.4GHz spectrum – there’s a real danger that 100 people in the church all logging on at once could cause the AV control to miss a connection, and leave the operator unable to open the mic of the speaker as the service begins!

You may need extra wireless access points in your building to extend the reach of the wi-fi, however, those intended for small household use have a limit on the number of connected devices that can be online at the same time. This can be as low as ten devices at a time.

Avoid the free or cheaper wireless access points, they’re usually worthÌýwhat was paid for them.

If your building is old and has thick walls and a lot of stone, the wi-fiÌýmay struggle to reach very far. It’s worth testing the strength of theÌýwi-fi in the building first, before investing in a system that might not suit you.

Once you have free wi-fi available

Do you have the space to offer aÌýcomputer for the community to use?ÌýDon’t forget, you need to make sureÌýit is in a secure place. You might alsoÌýneed someone available to help supportÌýpeople with low technical skills whoÌýwant to use it.

With more space, budgetÌýand resources, you could have moreÌýcomputers and offer classes for peopleÌýwho want to learn how to use one.

Some churches with available space have created co-working spaces.ÌýThese areas allow people who don’t work from an office toÌýwork at a desk outside their homes and meet other people.

If people are going to be around for longer, why not offer them aÌýplace to charge up their devices? Have a few different chargers andÌýadapters available. It can be frustrating when you’re out and aboutÌýand you can’t find anywhere to charge your phone or portable tablet.

Glossary of terms

Terminology can be confusing when it comes to wi-fi but we hope this glossary of terms will help you get to grips with the subject matter.

BandwidthÌý– the amount of information that can be transmitted over a givenÌýconnection. There are several bandwidth restrictions in a system,Ìýincluding the bandwidth of the wi-fi signal, and the bandwidth ofÌýthe connection to the internet from your internet or mobile-networkÌýprovider.

µþ°ù´Ç²¹»å²ú²¹²Ô»åÌý– aÌýfast internet connection with the ability to handle multiple voice,Ìýdata and video channels simultaneously. Cable and fibre are bothÌýbroadband channels; they provide much greater speed than dial-upÌýinternet access over telephone wires.

¹ó¾±°ù±ð·É²¹±ô±ôÌý– aÌýsystem that sits between two networks to prevent access by unauthorised users. The most common use of a firewall is to provide security between a local network and the internet. Firewalls help to stock hacking attempts.

±á´Ç³Ù²õ±è´Ç³ÙÌý– aÌýlocation where users can access the internet using laptops and other wi-fi enabled devices either for free or for a fee. Hotspots areÌýoften found at coffee shops, hotels, airports, train stations and other public meeting areas.

±õ²Ô³Ù±ð°ù²Ô±ð³ÙÌý– the internet is like a network of networks – an interconnected system that facilitates information sharing.

IP addressÌý– the ‘phone number’ of a device that is connected to the internet. An IP address is used to identify computers and devices connected to a network within a building (the LAN, or Local Area Network.) Buildings themselves have a ‘public IP address’ which is the address of that LAN on the Wide Area Network (WAN). Routers and IPÌýaddresses allow information, or traffic, to travel around the internet.

¸é´Ç³Ü³Ù±ð°ùÌý– aÌýrouter is a device that joins two networks together. It sends information from the internet WAN to your personal devices – like a computer, phone, or tablet – on the LAN. Many routers also have a Wireless Access Point (WAP) built into them, to provide a wi-fi connection on the LAN.

°Â¾±-´Ú¾±Ìý– wireless networking technology that allows smartphones, computers, laptops, and other devices to communicate with each other within range. There are two common frequency bands used by wi-fi: 2.4Ghz and 5Ghz.

Wireless Access Point (WAP)Ìý– aÌýpiece of equipment that allows you to connect devices which have wi-fi access to your wired network.

Local Area Network (LAN)Ìý– aÌýcomputer network that links devices within a building or group of neighbouring buildings. Some features of buildings (e.g. walls) can limit the effectiveness of an LAN.

Wide Area Network (WAN)Ìý– aÌýcomputer network connecting devices that are far apart. A WAN is typically more powerful than a LAN and will be better for some churches.
