rashbre central: getting wired

getting wired

It started with Cat 5 and then Cat 5e . The cables that everyone uses to connect their wired ethernets together. Nowadays many people don't even bother with wires, preferring everything to be beamed over wifi. 

They are the ones who will eventually lose their photos because they forgot to back everything up. 

I've got cabling as well as wi-fi and some of it is built into the house.


The electricians who wired it used Cat 5e cabling, which can run at up to 1Gb. I've noticed though, that on the long run between upstairs and downstairs, I sometimes get a negotiated 100Mb (ie 1/10 of the speed). 

That is where the length of the cabling starts to have an effect and is why more recent specifications up to category 8 are increasingly include better shielded cable twisted into pairs. It is quite different from the ancient Category 1 bell-wire.

Now I can't really justify having the house cabling ripped out, so I'm looking at other solutions. Roll-up IEEE802.11bz. It incorporates a clever way to squirt faster speeds down a lower speed-rated cable. Get the Category 8 effect from a Cat 5e cable.

The downside is that no-one supports it yet, or at least doesn't publicly feature it in their advertising. I looked around and found that 'Multi-Gigabit' seems to be an alternative name for a similar technology. And thus I found a little box which can slam 2.5Gb down a 1G cable. 

I hope it works!
