Theoretical Powerline Adapter Speed Question

On another forum, I read an answer to a question about TP Link AV200 Powerline adapters that I just wasn't convinced was accurate, so I wanted to ask it here.

We know that house wiring is a big factor on the speed one would get through a powerline adapter, so I'm not talking about that.

The question is, in a perfect world with perfect wiring and everything set up right, could the AV200 actually transmit a speed of 200mbps (as long as the ISP is at least 200mbps)?

What I read was the max speed an AV200 could do was 20mbps and the max speed an AV500 could do was 50mbps. I was under the impression the AV200 could do max of 200mbps and AV500 could do max of 500mbps. (hence the names: AV200 and AV500)

Can someone confirm or debunk this?

I kind of made sense after I read it because, in my situation, I have 50mbps coming from the ISP and the max I'm getting with my AV200 is 20mbps, but I just chalked it up to the house wiring.

Thoughts?

Check against your manufacturer, but they probably use different algorithms for the signal processing, they can co-exist on the same mains, and I suppose if you connected a 500 to a 200 they'd all form part of the same network.

Depends...

20MBps is roughly 200Mbps - so this might explain some of the issues.

However unless they have Gigabit network ports they are limited to 100Mbps out of the device anyway, between each other they may be able to hit 200 or 500, but between the device and the outside world they'd be limited to the port.

There are some with gigabit ports, but not all have them.

If you upgraded to 500's then you might find that you get 50Mbps as you are still not constrained by the ports

Even "perfect" power wiring would still be horrible for high speed data transmissions due to all the wiring stubs (appliance cords) disrupting wiring impedance, causing signal reflections and other transmission line effects that would degrade transmission speed. An ideal house wiring would still have a breaker box and powerline networking signals would still need to go through the breaker box to reach outlets on different circuits, there is no avoiding the performance losses from that either.

You will rarely manage to get anywhere close to the alleged speeds unless the two adapters are on the same branch circuit with nothing else on it. But when the two devices you want to network over powerline are close enough to be on the same branch circuit, they are usually close enough to connect over Ethernet instead.

So, if I'm understanding correctly, since I'm getting 20mps connecting two AV200 on my 50mps line, if I would upgrade to the AV500's, I should get more speed, with everything else being equal? Is that a correct assumption?

Also, would the AV200 and AV500 work with each other? Are they compatible?

Network performance depends on the speed of the slowest device in the chain.

200's probably won't talk to 500's.

But yes a 500 should do better than a 200 providing you are getting below the port speed (which you are at the moment).

What? the 500 and 200 won't talk to each other? That's depressing. I already have several 200's around the house and was going to get a set of 500's, use one of them as the main AV (connected to the modem/router) and then just re-pair all the other 200's to it. But, if they don't talk to each other, that would be pointless, yes?
