A question we are often asked at Sound Networks is why can’t I get a faster internet connection? Well, the simplest answer is geography. But that doesn’t cast much more light on the issue at hand for most people. The speed of your internet depends on many factors and it’s important to understand what kind of connection you have in the first place before we can go any further. Some of (but not all of) the most common types of internet connection currently are…..
- ADSL Max – also known as 20cn. An older type of copper based internet connection which uses your telephone line. An adaptive service reaching a max speed of 7.15 Mbit/s downstream.
- ADSL2+ – also known as 21cn. Also an older, but slightly faster type of copper based internet connection which uses your telephone line, max speed 24 Mbit/s downstream.
- VDSL/FTCC (Fibre To The Cabinet) – getting faster. Still uses your copper phone line in to your building, but the nearest green street cabinet which you are connected to will have fibre running to it from the local telephone exchange. Theoretically only the ‘last mile’ of the connection to your house is copper based. Not always a mile, but the longer this connection – the slower your ultimate speed will be.
- Fibre Broadband/FTTP (Fibre To The Premises) The fastest of all the above with speeds of 150 Mbit/s downstream and above not uncommon. With this connection you will have a fibre connection all the way in to your home to your router or cable modem. Most commonly provided by your cable TV provider in conjunction with a TV and telephone package.
So with the first of these three, as a general rule of thumb, the farther you are from the street cabinet and it’s ultimate distance from the local exchange, the poorer your connection will be. This loss of performance can also be contributed to by poor quality or degraded copper in this last section. If your connected cabinet is too far from the exchange it may not be possible for it to be fibre connected. You may find that you live very close to the exchange but cannot receive anything faster than ADSL2+, in this case it may be that you are directly connected to the exchange and your connection has currently missed out on being included in a fibre upgrade. If you have a fibre broadband connection…..well, your probably not currently experiencing internet performance issues or even reading this blog!
For business, there are a multitude of other types of fast internet connection types available – let’s talk about that another time.
