TPL-303E2K Up to 200Mbps Powerline AV ?

[stevech]

anyone used these with success?
Price is low enough to make one wonder.

It was disappointing that they would not work plugged into a pair of UPS power strips

again makes me, a user of MoCA, wonder if power line modems have the same hassle, or more so, as does X10, with "signal suckers" (attenuators) in power strips with filters/suppressors, and the big question I've had before: how can power line modems bridge across two-phases in US home wiring?

Yes, they do. Anything that attenutates high frequency will knock down powerline networking signals.

and the big question I've had before: how can power line modems bridge across two-phases in US home wiring?

asked and answered before. But you still don't believe me.

You should just get a pair and see for yourself. I suggest you get a pair of NETGEARs, they tend to have more up-to-date firmware.

With X10 in US residential, a phase bridge between the two phases is needed to get adequate signal strength on the opposite phase from where the X10 source(s) are. The bridge is simply a bandpass filter for the relatively low frequency of X10's carrier (about 100KHz). Usually goes in breaker box. Some 220V appliances might bridge when turned turned on. Poor or weak other-phase signals bedeviled X10.

With power line IP, the frequency is of course hundreds of MHz not KHz. So cross-phase coupling might accidentally happen more so than at X10's frequency.

I am looking for multiple user stories on this. My own one-of experience isn't a good indicator of the widespread success. And.. the engineer in me wants to know the principle on how phase bridging can work, rather than "mine does, yours probably will too". Forever a geek.
