802.11G802.11G is capable of streaming video, while not optimized it can pass just fine compressed at 2.5MB/sec video.
For a H.264 video file that will be more than enough for some HD content, the problem is only range. | |

Re: 802.11Gsaid by Anonymous_:um WiFi G can do 24mbps nice try Maybe you missed the part where he said MegaBYTES and not MegaBITS. His number and yours are roughly equivalent. And G doesn't always get to 24 mbits/sec. It often tops out at 19 or 20 mbits/sec. | |

Re: 802.11Gthat is on the el crapo routers you only need 19.2mbps for an hd Stream any how or 1.5Gigbit/s for uncompressed with DD-WRT installed you can get 24mbps see here » dd-wrt.com/phpBB2/viewto ··· hp?t=341 | |

Re: 802.11Gddwrt does not automatically guarantee those speeds. I have 27 access points visible from my HOUSE and it's probably worse in some apartment complexes. | |

In my house, one floor above or below my access point, speeds drop to about 10mbit.
In my apartment, I'm to get as good as 10% packetloss to the building wifi, IF I even can connect at all. I need to have a dd-wrt router sitting a foot from my front door acting as a relay to even get that good of a connection.
The fact is, your theoretical speeds on your non "el crapo" routers are all well and good, but they don't exist in REAL world situations where signals are shoddy and every client shares bandwidth.
Wireless networks are like a hub, not a switch. If your network can pass 24mbit, one single transfer between two wireless clients can do at most 12mbit per second, since there are two transmissions involved (your PC to AP, AP to remote PC). As the number of clients on an access point goes up, the possible speeds drop in a non-linear and quite startling way.
And forget about mixed mode! With all those 802.11b devices out there polluting networks, speeds drop even further. Even in a home network, annoying 802.11b devices pop up. The Nintendo DS (802.11b and WEP only), and the Nintendo Wii (802.11b and WPA) are examples. The solution there is to set up a second network for the Nintendo and other 802.11b devices, a non-ideal solution.
So, 802.11g isn't fast enough for standard HD streams if both devices are wireless, even under ideal conditions. 802.11n bumps up the bandwidth and range so much that it's pretty much required to make this work. And even then, 802.11n isn't as big a leap as I'd like.
Wikipedia says the throughput for 802.11n is 74mbit (contrasted with 802.11g's 20mbit throughput). That 74mbit goes fast when you put a few connections on it. Already you're limited to half that when two wireless devices are communicating, or 37mbit. Yes, that's fast enough for an HD stream, but add more clients and throw in mixed mode and speeds will degrade very quickly.
I think we'll have such throughput issues until actual throughput speeds hit a gigabit or so. Assuming this happens relatively soon, by that point we should be beyond the "it's not even fast enough to do XYZ" phase. | |

2011?They are basing a recommendation to buy N gear now, on what the market will be like in 2011? That's atleast 3 laptops down the road for me. (though the current is already N)
But anyone who isn't the type to upgrade for another 4 years, also probably isn't the type to buy the latest right now either. | |

Re: 2011?Umm think about this everyone:
Who of you still use 802.11B routers exclusively?
N is backwards compatible with G, just as G is with B...
It's only natural that new devices will all be the new N standard, but operate with G equipment. Duh. I don't see why this is news? | |

I rarely do LAN file transfers. Cable is only up to 6 Mb/sec. | |

Re: Phased out where?wired certainly is the way to go if one is serious about any kind of home-media use. wi-fi was never intended as a way to run an amateur tv station in the home. | |

Re: Phased out where?i don't see how anyone who only has the means for a notebook and/or an apartment can justify the enormous cost of 802.11-anything compared with el-cheapo NIC's and CAT-5. i mean, if it were me, i'd rather have CAT-5 strung through the apartment to gig-E switches and NIC's, all of which would cost just a little more than a turbo-charged wi-fi system and do much much more. | |

personally id run Cat6 in any new construction. heck have cat 6 with every electrical outlet if you want to spent the money. and a nice fat gigabit switch in a closet.
ps i know a network jack by each plug(outside of the kitchen) would be totally overkill. | |

As long as 802.11a is around...I'll be sticking to it. It is fast enough and it is out of the morass of a spectrum called 2.4ghz where every Dick and Jane in the neighborhood has their access points.
Of course if I'm going to do anything with streaming video in my home, it is going to be across GigE. I'm not one of those pansy ass people who is too stupid to know what the wires in his entertainment setup are for and how to hook them up. | |

G will still have good uses.said by KathrynV 's summary :The reasoning behind the study is that 802.11n can be used to wirelessly route video throughout a home and therefore itll be the most sensible thing to use for routing which will require all devices to be compatible. I understand the need for N, but phasing out G is ridiculous. This device and this device will probably never need anything faster than G. Also, I have never had trouble streaming video over my wireless-G network. This is just FUD to make people go buy all new unnecessary hardware. I wonder who paid them to do this "analysis." Someone like Broadcom maybe? | |

TV? No prob!SD TV is a non-issue for "g" wireless... I do it all the time! MPEG2 @ 8mbps... works fine! Now, Blu-ray across "g"? Not happening. Upwards of 48mbps(audio & video combined) for some discs. | |

When finalized I'll consider moving to 802.11n AFTER the spec is finalized. Who knows what changes (if any) may occur between now and then? Besides, G does everything I need for a wireless to do for me. Why spend the extra money now? Prices on computer stuff always drop with time. I'll just wait until the time is ripe. | |

Re: When finalizedSame here. I am not wasting my money on un-finalized gear. Most of my computers are wired anyway. I run one computer wirelessly, which is the laptop. | |

I'm waiting too until it's a standard spec. I wish I could do everything wired, but that's hard when computers are on different floors. | |

So confusingWe use the 108 Netgear wireless stuff so it probably connects at what, 60mBps? It works fine for XBoxLive and computers. No issues there. However, my kids like to watch movies that are based on my computer. Today's wireless won't do it, 100mBps wiring won't do it, only gigabit (1000) will transfer movies seamlessly without bothering me on my computer and without problems on the kids computers. I've already decided my next router will be a gigabit router and I'm looking for a NAS that is gigabit since transfering large files across a 100 network using the NAS takes too long. As for N, who knows what to buy? The various flavors of pre-n don't work together, right? | |

With N, there is some compatibility, like with Broadcom and Qualcom. We're in draft 2 now as well, so I think any hardware subscribing to said draft should (theoretically) be functional with the rest. The Asus WL-500W promises to be standard compatible as well. See this guarantee: » event.asus.com/2006/wire ··· ss/pren/ (free firmware OR hardware upgrade, whatever is required). | |

N speedsI have a dlink extreme draftn router. Nice piece of equipment, great range. We also have several notebooks with certified n cards.With the network encrypted(as it should be) we run at G speed 54Mbps.Only with the network wide open(sure ) can we see speeds over 175Mbps..... | |
