So there is interference? ;)

Wasn't the claim before that there was no interference? :o

And whoever wrote that article needs to have their spell check looked at.

Try again.

DS2's Radio Friendly BPL Technology puts Competition on the Defensive
Hello, Unknown Investor! Both Ambient and Amperion use DS2 chipset technology and both have had systems with interference problems. Amperion had three systems with open complaints deactivated. Ambient's Briarcliff Manor, NY site has several complaints as well, though is still in operation.]]> http://www.dslreports.com/forum/remark,15062425 Tue, 20 Dec 2005 08:18:36 EDT Re: Interference Potential...not with DS2 technoly http://www.dslreports.com/forum/remark,15061278 anon : read this article !!!

DS2's Radio Friendly BPL Technology puts Competition on the Defensive

Speaking at 2005 UPLC Annual Conference, Victor Dominguez, DS2's Director of Strategy and Standardization, outlined the reasons why DS2's 200Mbps powerline solution is the only regulatory compliant technology available for BPL commercial deployments.

Dominguez was dismissive about claimed alternatives to DS2.

Mr Dominguez was adamant about competitors claims "I think that we have put the competition on the defensive. Our competitors would love to have the flexible notching capabilities that we have for BPL and In-Home PLCs, but the truth is that they don’t. DS2 has had dynamic notching since its first chip set and can mitigate radio interference in a programmable way and other PLC chipsets do not. We would like to thank our competition for the rumours propagated at several press interviews, they have been attracting attention towards one of the main competitive advantages of our technology, we mastered programmable notches in a 200 Mbps chipset more than 2 years ago, since then we have been shipping in volume for BPL and In-Home applications, and still remains to be proven that competition can follow us.”

DS2's technology is well known in the BPL industry for being one of the first proponents of programmable notching in powerline communications, as the best method for addressing potential interference to radio services. DS2’s 200 Mbps BPL technology, available in silicon since 2003, already implements this dynamic notching functionality, which has been tested in the field, in several commercial BPL deployments, and demonstrated in several BPL industry trade shows.

“Other competing technologies have some notches, but they are fixed, including the most advanced designs from followers (on top of that they exhibit performance below 40% our speed). This means that they fall short for the demands of regulators and consumers everywhere from the FCC to the European Commission who require that frequency bands can be selectively notched out, even after the equipment has been deployed. Operators deploying non-DS2 based solutions risk having their equipment withdrawn from the field because once it is out there, there is nothing that can be done to prevent interfence with radio signals. With DS2, however, any issues can be resolved even when the equipment is in the field by remotely disabling problematic frequencies thus complying with today's or future regulatory requirements and automatically avoiding any radio signals in any part of the world". Mr Dominguez placed special emphasis on the radio friendliness of the system.

What system are they running in Cincinatti?

Motorola?]]> http://www.dslreports.com/forum/remark,15058613 Mon, 19 Dec 2005 19:00:24 EDT Interference Potential http://www.dslreports.com/forum/remark,15055928 rf_engineer : Current has been one of the better companies as it relates to interference. They've been running the Cincinatti trials which have done well; they tend to stay out of amateur radio bands and in general avoid HF bands. Other vendors like Amperion and Ambient have had less than stellar interference track records. TXU had dumped an Amperion trial earlier in the year due to interference.

A ten year deal is pretty aggressive. This will make or break some decisionmaker's career at TXU :-)]]> http://www.dslreports.com/forum/remark,15055928 Mon, 19 Dec 2005 12:18:16 EDT
