| Re: wireless networking said by jchambers28  :that's some crazy shit I am doing that here and it don't work that great. there goes your 1080i I agree. I tried it as well and it was awful. I was only going through one floor and about 15 feet maybe. The issue was the reliability of the connection, not the max throughput that could be achieved. I eventually replaced the bridges with Motorola NIM-100 MoCA bridges and see a solid 100Mbps all day.
I could hit 280Mbps (802.11n Draft 2.0) but every 2-3 minutes the signal would get muddled and the rate would drop, causing a video pause. Actually, when the rate had to change at all, either decrease due to a interference and then when it cleared up and increased the rate again, I'd would experience problems. The 5GHz spectrum would help, so I hope they are deploying it there. | |

| Re: wireless networking Personally, I'd rather use Ethernet over powerline (Netgear HDX-101 or newer).
I typically have ~100mbps to almost any outlet in my house (100mbps port, so ~70mbps throughput).
The only issue occurs when there's something with a high load (microwave oven, vacuum, hairdryer). | |

| Re: wireless networking 1080p Blu-Ray discs usually run around 30Mbps, which is well within the real-world performance of 802.11n (60+ Mbps).
You can get excellent quality 1080p video with H.264 at 15Mbps, so you could easily send three video streams simultaneously over 802.11n.
The major stumbling block is going to be interference, but there's a good chance that AT&T will be using the 5GHz band instead of the 2.4GHz band (802.11n can use either). | |

| Re: wireless networking I have no issues with MoCA, however these devices are plug/play, no config required either. Its basically an ethernet bridge over 120V, usable at any outlet.
My longest run is probably ~300' of wire (far end of house to circuit breaker and back over a different circuit, and I have ~70Mbps (~55Mbps thoughput) - and my electrical is aluminum :P | |

And yes, the 2.4 GHz spectrum is ugly in many areas with 5 GHz quickly catching up. I'm surprised AT&T is attempting something that they will have absolutely no control over. At least with MoCA and existing phone line connections, they have control and can run new coax drops if needed. | |

This has (predictably) turned to shit just like CB did thirty years ago, and digging a new hole everytime the latrine fills is an exercise in futility. Unregulated radio transmission always ends up being a putrid mess.
White space devices would not escape this either, and you can forget 700 MHz.
How about going back to the almost-unused 900 MHz band? | |

| HomePNA I've found wireless to be VERY unreliable in terms of bridging points around the house. The average throughput was adequate, but the instantaneous transfer was highly variable. Neighbor turns on a microwave, switches on their baby monitor, or picks up their 2.4GHz cordless phone, and your movie is done! Even with a fair amount of buffering (which takes time while seeking), you would always have a few hiccups. Furthermore, even 802.11n does not have the bandwidth to stream more than 1-2 HD streams over more than a few ft. From my experience, I seriously doubt this will be a viable solution for most people, especially those in urban areas.
I've never used homepna equipment, but the coax moca bridges I have (nim-100's) are bulletproof. They run internally at 254mbits even over half a dozen splitters and REALLY crappy coax in my house. They introduce only about 5 ms of latency, and I can pull the full 100Mbits out of the ethernet port. | |

| I hope they're using 5.8 GHz... The best parts of 802.11n simply won't work on 2.4 GHz networks along side other 802.11b/g networks, cordless phones, baby monitors, security systems, AV setups, and etcetera. That gloriously generalized statement happens to be true for over 95% of the population. Sure, they can set their APs to ignore interference and force bonding and phasing, but when they do that, then they're the cause of interference.
I hope they're planning on using 5.8 GHz for this.

This is incorrect. They use either HomePNA or straight Ethernet over Cat5/5e/6, or a mixture of the two. The installers prefer Ethernet if the cabling is available. | |

| 802.11n in the 5GHz range 802.11n in the 5GHz range (this is the same frequency that 802.11a uses) eliminates much of the interference problems associated with 802.11b/g deployments. The 5 GHz frequency does not travel through solid objects as well as the 2.4 GHz frequency, but it should work well enough in household areas. The 5 GHz channel will also allow for up to 20 non-interfering instances, so it will play well in high density deployments (apartment buildings). 802.11n also employs WPA2-AES encryption by default, so this, in combination with non-broadcast SSIDs, will keep neighboring implementations from "snooping" on what each other are viewing. | |

Dumb move. It's not gonna work. Just like cellular and wimax, microwave transmission is best-effort at best and susceptible to everything else in the spectrum that shares time slices in the same space.

| Shortcuts much? Well what else is new, seems like everyone is trying to take shortcuts and trim off the extra fat for savings (ex. Verizon's selloff of less profitable states).
Wireless is not the way to go for HDTV and other stationary networked devices. 802.11 should still be focused on being applied for mobile devices and not stationary ones. There just isn't the reliability and stability of 802.11 yet even with N. For the near future, it's just another possibilty for something to go wrong on the customer's end.
I think if AT&T wants to go ahead with this, it should be OPTIONAL to the customer if they agree and are tech savvy enough to troubleshoot majority of issues on their own. Otherwise this will only reduce the quality on the end user if not properly configured and maintained.
