Let's Get Up To Speed

The term “broadband” is essentially an overarching term used for the provision of high-speed internet connections to customers premises, using a wide variety of technologies. Some of these technologies will be more familiar, such as the more consumer focussed and very common ADSL (provided by BT, O2 and PlusNet etc.), other more business orientated options such as EFM may be less familiar.



Bandwidth is the amount of information that can be transmitted down the internet connection at any time. The more people using or sharing your broadband connection, the more bandwidth you will require. Two figures are often stated such as 80/20 FTTC, in this instance, the 80 being down and the 20 being up and FTTC the product type;

Download or Downstream – The amount of information you can access from other sources.

Upload or Upstream – The amount of information you can send to another place.

It might come as no surprise that in general people download more information than they send. This is the reason why on the majority of connection types, the download figure is the higher of them.

Asymmetric or Symmetric

It sounds more complicated that it really is; as mentioned, generally the majority of users will download more than they upload, but this is not true of everyone and some need just as much upload bandwidth.


  • Asymmetric – The download speed will always be greater than the upload speed


  • Cable Broadband


  • Symmetric – The upload is equal to the download speed or (Symmetrical)

  • EFM

  • SDSL

  • Fibre Contention


Back at the exchange users are “grouped” together. Generally, for businesses, 20 connections share bandwidth together and this is known as the contention ratio or 20:1. If all use their connection heavily none will achieve their maximum speed. An un-contended or an Assured product ensures the user receives 100% of what they are paying for.
