Broadband Speeds FAQ

 

Q: What is the speed of the Digital Region service?

A: The advertised speed of Digital Region services is "upto 40Mbps" but what does this actually mean? Our network topology is based on FTTC (Fibre-to-the-cabinet) services, which means your business broadband is driven from a local hub which should never be more than 500 metres from your premises. This translates to average estimated service of 25Mbps actual download rate, you could receive 66Mbps! But the actual figure cannot be confirmed until your service is installed, due to multiple variables such as quality of copper and proximity of interference or even the qulaity of the wiring within your premise.

 

Q: Why is the advertised speed not always what you get?

A: All broadband companies use the same BT copper lines to deliver service, most technologies used today are known as rate-adaptive: meaning, rather than offering a fixed bandwidth or speed, within the first week of service they will settle on the highest stable rate your line can support.. The rate that your line settles on will be affected by factors such as the length odistance between your premises and the Digital Region Broadband node, the quality of the copper, and the amount of local electromagnetic interference, which usually don't change from one broadband provider to another. Usually this means that the speed of your local line will be very likely to remain the same from one provider to another regardless of the speed advertised, although our products will be dramatically faster as they are not served from the exchange (explained above)

It should also be noted that with rate-adaptive broadband this speed can change: for example, an increase in local interference can sometimes mean that a line drops down in speed, although it should also eventually return to the previous speed if the interference returns to previous levels.

 

Digital Region has conducted successful trials of VDSL2+ technology and continues to roll it out as a the standard option. VDSL 2+ will guarantee increase of a customer's speed.

 

Q: How does the fibre-optic technology in FTTC help?

A: Fibre-optics offers much less signal degradation over distance, as well as being less sensitive to interference, your business traffic will pass over fibre optic cables from your local Digital Region node directly to the core of our network. We do not contend traffic on our core. 

 

Q: Your service is advertised in Megabits - What is the difference between bits and bytes?

A: Computers talk natively in binary code – a stream of ones and zeros (eg : 0011100011). A ‘bit’ is a single one or zero, and line speeds tend to be measured in terms of how many of these bits can be transmitted in a second (so 8 megabits is 8 million ones or zeros each second). File sizes and disk capacities however, tend to be measured in ‘bytes’, which are simply blocks of eight (8) bits. So if you want to go from bytes to bits you must multiply by eight, and if you want to go from bits to bytes you must divide by eight. Your line speed is advertised in mega (or millions of) bits per second, but your usage limit is measured in Giga (or billions of) bytes per second. However, this is only approximate, as broadband networks add overhead so only very crude calculations of expected download time can be made using these basic numbers.
