HPNA 3.0...128mbps and beyond!

[Tokar]

FINALLY an update at the HPNA Homepage.

June 4th press release (yeah its June 12th today, but i visit the site like once every now and then and today was the first time i visited it in a long time):

The Home Phoneline Networking Alliance (HomePNA), the organization driving the development and adoption of a single phoneline networking technology, set a new standard for home networking today by finalizing its third-generation technology, HomePNA 3.0...HomePNA 3.0 silicon products supporting adapters and bridges are expected to be available later this year.

I knew this would happen shortly after I got my house wired for Cat5... It seems like a great deal, if it works as claimed, and isn't too expensive. I think a reasonably priced combo 802.11g/phoneline device could be great -- no more hassling with reception problems, so long as you've got a convenient phone jack you can just place the wap in an optimal location. Some powerline devices have tried to do that but they don't seem to have done very well.

One thing I wonder about -- if crummy phone wire is capable of 128mbps, then why couldn't cat5 go 1gbps or better? And cat5e and cat6 do much better still?

who knows who cares...probably just capitalism...

they figure, i guess, that to get gigabit speed you gotta pay for NEW wiring (thats if you have existing 100mbps wiring) they might as well leave old cable as it is and not make it better such that they can get more out of our pockets for the upgrade...

128 Mb? Sounds too good to be true. Wonder if HPNA accepts a very high error rate?

I'd like to see some test results. Even poorly installed cat5 won't run 100 Mbs.

I think this is the critical paragraph from the press release -- al though darned if I understand what it means. What is "best effort" data and "deterministic Qos"?

Deterministic Quality of Service makes HomePNA 3.0 unique among ?no new wires? home networking specifications in its ability to deliver multiple high-speed real-time audio and video data streams without disruption in addition to ?best effort? data. While HomePNA 2.0?s QoS enabled equipment manufacturers to prioritize telephone voice data higher then computer data, multimedia home networking requires much stronger QoS. HomePNA 3.0 greatly enhances version 2.0 capabilities adding deterministic QoS support for real-time data. The technology permits users to assign specific time slots for each stream of data guaranteeing that the real-time data will be delivered when it is required with predetermined latency and without interruption. This capability enables providers to offer ?triple play? services of POTS, high speed Internet access, broadcast and on-demand video over the home network to lower customer churn and increase revenue per customer. It also allows HomePNA V3 to transport data with inherent QoS requirements such as IEEE1394.

won't most cat5E support gigabit?

 

[TechBoyJK]

yes it will. it could probably support 1000GB ethernet too, but "they" won't tell us that.
