DirecTV offers access point, set-top box with top-notch 802.11ac Wi-Fi
 
The Internet and TV provider announced today that it has deployed the WVB access point (AP) and the C41W set-top box to customers. Both of these devices are equipped with Quantenna's 4x4 802.11ac Wi-Fi technology.
 
Full Story Here
 
EDIT: The story at CNet has been pulled.  Some of it was old news, and some of it was flat out incorrect.

I guess CNet pulled up the review we did in July and thought maybe they would write a story about it. Don't know if that's funny or sad. http://www.dbstalk.c...s-video-bridge/

I tried a search here for the AP (knew about the C41W), and may be just as confused as they are now. 

 

Fell free to delete my posts, but what is the Access Point part of the story?  And why are they saying it's released today?

Is it really an 802.11ac access point? It says it's 802.11n in the first look. :shrug:

It's not being released today. What CNet calls an "access point" is the wireless video bridge, nothing more. It is not an access point for any other device in the home.

DIRECTV confirms that the C41W and WVB do use a closed WLAN and the chips are capable of 802.11ac. The field testing process had us referring to it as 802.11n... make of it what you will. We don't discuss the specifics of field testing.

Does this mean we would need a router compatible with the Quantenna's 4x4 802.11ac Wi-Fi technology?

No, if you get a C41W you will also get a Wireless Video Bridge (WVB) that will act as a private access point specifically for the C41W. It will act completely independent of your router.

No not at all. It's an entirely closed system and creates a separate wifi network just for it. Has nothing to do with any wifi you already have in your home.

Thanks for the info guys. Yesterday they installed an HR44 with 2 C41-100 clients and began a 2-year commitment, so I'm wondering if I could get this new upgrade. Seems like the main advantage would be ability to access VOD with all at the same time, aside from using DTV network and not drawing from your home network, which is also nice.

 

I want it! :)

Not at all what this is! Ugh!

It's just talking about the c41w and the wvb you need for it. Read the first Look for the c41w in the first look section here.

I couldn't find that C41W first look. I saw the C41 listed but not C41W. Do you have a link?

Is there a typo in the first link or did CNET realize how old and misleading it was and take down the review?

No typo - they woke up and pulled it.  The claim of a free AP had me confused, as I said earlier..........

 

I'll update the first post.

On one hand I guess I can sort of understand CNET's confusion here if the following is the case.

 

Its called "Wireless Video *Bridge,* " and technically at least, wireless bridges only communicate with another single wireless access point (usually the one integrated into a router) in a point to point link, or another wireless bridge in a likewise single p-p link..

 

Whereas the "WVB" used by DIRECTV is a WiFi bridge that can actually communicate in a point to multipoint topology with multiple WiFi clients (C41Ws in this case) which is like what an "Access Point" (or AP) does.

Yeah, sorry, that's not an excuse. They make it sound like a regular access point. It's just really bad writing.

Except for some limited satellite-delivered PPV movie type stuff, the VOD content still comes through your home broadband connection to the Genie. The WVB just transfers that same content to your C41W client wirelessly over a private network. The C41 gets that content from the Genie over the DECA network, again off your regular LAN.

So you're saying even with the C41W, VOD can only be accessed on one device, such as either HR44 or one C41W client? That is how it is with the C41.

Yes.  The c41w works exactly like a c41, only it doesn't have to be hard wired to the system, it can connect to the genie wirelessly.  But it still goes completely through the genie.

Well, in that case, the only advantage for me is it doesn't use my home network, which is nice. What would be more exciting is if it allowed more than 5 recordings at a time, or more than 5 combinations at a time, such as 4 recordings simultaneously and watching more than one live show at a time. I guess that means more than 5 tuners.

 

Still, I can see where it will benefit many others in its present state.

On one hand I guess I can sort of understand CNET's confusion here if the following is the case.

Its called "Wireless Video *Bridge,* " and technically at least, wireless bridges only communicate with another single wireless access point (usually the one integrated into a router) in a point to point link, or another wireless bridge in a likewise single p-p link..

Whereas the "WVB" used by DIRECTV is a WiFi bridge that can actually communicate in a point to multipoint topology with multiple WiFi clients (C41Ws in this case) which is like what an "Access Point" (or AP) does.

Not to confuse anyone further, but in LAN terminology a "bridge" is a device that connects two LAN segments at the physical layer. In other words, it bridges two different network topologies. The DECAs are "bridges" that connect MOCA based coax to standard twisted pair Ethernet. The WVB is a bridge that connects a wireless segment to standard twisted pair Ethernet, so the terminology is correct.

So...

Bridge: a device that transfers data from one network topology to another, usually without any routing (any data packets on one segment are transferred to the other)

Hub: a device that transfers data from one LAN segment to another of the same topology, without routing

Switch: a device that transfers data from one LAN segment to another of the same topology but only transfers packets addressed to nodes on the target segment.

Router: a device that transfers data from one or more LAN segments to others of the same or different topology, with address and session based routing.

Gateway: a device that combines a router with network address translation (NAT) which substitutes it's own IP address for those of the nodes on one side of the router when transmitting on the other segment (this is a distinct technology from the router itself). Most gateways also include filtering, which blocks certain kinds of packets (like "pings") from passing through the gateway in one or both directions. Most modern gateways include stateful packet inspection (SPI) that prevent sessions from being initiated from the "outside" segment.

The standard home "router" is really a gateway.

The C41 doesn't use your home network either; it's networked through DECA over the existing coax. So really, the only advantage of the C41W over the C41 is the fact that it can be used in places where coax isn't run, or for a portable TV setup around the house (like maybe a TV/receiver combo you carry out onto a deck or something).
