Some of you will be aware of how the internet works but for those who are unsure, please read on….. This page will briefly explain each part of the network that creates the internet. We focus on the UK domestic side and how its constructed. Most of the UK will be connected via BT/Openreach using a xDSL based connection, via an ISP like TalkTalk, Sky or Plusnet (Etc),
Your ISP (Internet Service Provider) will either have equipment embedded in the local exchange or rent capacity from Openreach in this style:
This product is known as FTTC or Fibre to the cabinet as part of the GEA (Generic Ethernet Access) solution and offers VDSL technology up to 80Mbps download speeds and up to 20Mbps upload speeds, these speeds will drop away fairly quickly the longer the line. If you have a line longer than 1km from the cabinet, then you’re looking at very low speeds.
If you’re with VirginMedia, it’s just like the above but using coaxial cable and DOCSIS technology. If you’re with Hyperoptic or Gigaclear, it’s likely it’s full-fibre all the way.
