Traditionally, most home broadband services in the UK have used fixed-line technology where either a phone line or cable runs to your home. This works well for many people though it’s often slow to set up and not that flexible as you’re tied in to a contract. In certain locations, fixed-line broadband can also be slow (e.g. in rural areas or households without access to fibre broadband).
As an alternative to fixed-line broadband, 4G or 5G wireless broadband can be a good option. It’s normally more flexible than fixed-line broadband and may give you better performance in some areas (e.g. in rural areas without slow fixed-line broadband).
