What speed do I have?
So called ‘fibre to the home’ (FTTH) broadband where the fibre optic cable goes all the way to your house, your speed should be very close to that advertised.
However, if you have ‘fibre to the cabinet’ (FTTC) you have fibre optic cable to the local junction box, and then copper wire from there into your home. If this is the case you may see a slower speed the further you live away from the junction box.
That said, there’s probably not a lot you can do about this and even with FTTC services, your broadband should be fast enough to handle most smart TV applications without a problem.
If you’re on copper wire, standard broadband, where you live matters a lot. If you live very close to the exchange, you’ll have more chance of getting speeds closer to the ‘up to 17 Mbps’ you’ll often see advertised.
The further you live from the exchange, and the further your house is from a local junction box, the slower your service will get. For some rural areas in particular, actual speeds can be just a fraction of the ‘up to’ speed.
With standard broadband then, you need to check your actual broadband speed to determine whether your connection is capable of supporting your smart TV.
