Effect of cold on broadband speeds

My understanding of physics is that such an effect will only be noticable at very very cold temperatures.  Much colder than the south pole! 

 It may feel like  a drop of 10C is significant but when you remember that the scale goes all the way down to -273.15C, 10 degrees is neither here nor there.

If there's a dodgy connection somewhere, cold could well make a difference.  Usually for the worse, as it tends to be associated with damp, though.

AIUI, there's likely to be less interference from medium-wave radio signals in the winter, on account of the changes in the ionosphere.

But it might just be random acts of our-favourite-telco.

Here in Silly Oak, I notice a measurable improvement in ADSL performance (that is, the raw parameters of the physical connection  between modem and exchange, rather than anything related to contention) outside of term time, when 90% of the houses are unoccupied and associated sources of interference are switched off.  The wifi spectrum becomes a lot less congested, too :)

8 C to -2 C is a 3.6% temperature reduction.

 

I very much doubt it.

In retrospect it was a fairly fanciful notion,but 20% average speed increase is significant.Now if I could manage that on the Stoke Stage of the TOB.
