Fibre Alternative: Cellular 4G/5G Broadband

Fibre is generally faster, more consistent and with no data caps - so it is preferable where available. However, fibre typically has longer contract terms, takes longer to install and may require to consent of the building or landowner to run cables. Further, once fibre is installed its location is fixed - with mobile broadband you can take it with you, anywhere!

5G (or 5th Generation) is the latest version of mobile data technology being deployed in the UK today. It is the successor to 4G. The advantage of 5G is much faster speeds (often 200Mbps+) and lower latencies, and the ability to connect more devices simultaneously. The disadvantage is weaker signal strength indoors, so coverage is reduced compared with 4G.

All cellular networks impose limits on monthly data transfers, either as explicit allowances, or by hiding behind a "fair use policy". These limits are expressed in GB per month, and are there to stop excessive use of the mobile network, which would slow down the experience for everyone on the same mast. Despite advertising claims, mobile data is never really "unlimited" on a cellular network, with typically around a 600GB/month soft limit. This is typically enough for a very small office, but if you are a heavier data user, fibre (with no caps) is certainly the better option.

There is so much variability with cellular networks - speeds will be affected by signal strength, router placement, mobile congestion in the area, whether masts are operating efficiently, and even the weather. It is therefore impossible for anyone to guarantee a minimum speed on a mobile network. Cellular services are always delivered and supported on a best-efforts basis. If guaranteed bandwidth is required, consider a fibre leased line instead.
