Re: [General] VOIP over Wireless LAN?
Thanks for the reply. What I have in mind are four bridges, with each connected to two or three PCs and two or three VOIP ATAs.
I know that the topolgy is invisible to VOIP, just as, in theory, a dial-up connection across ethernet would be. However, what I am trying to get at is if the quality of the call would suffer, particularly since VOIP would be sharing the wireless pipe with data activity. Since these are business lines, the quality and reliability are critical. Any thoughts? |

IMO VoIP may not be ready as primary business lines. FAX lines are by far more reliable on hard-wired PSTN. Voice lines should use g.711 and need a minimum of 90K upload and download each.
The ISP is going to make or break most of your success. The wireless part, if working without interference, is more a side-bar to your plans.

| I appreciate your perspective on VOIP for business use. However, since I have already made the decison (and have signed contracts for) going that route, what I really need are some revcommendations and thoughts as to what, if any, wireless LAN equipment can best support VOIP in the configuration I described in my previous post. |

My wireless networking experience is with 2.4 Ghz 802.11b Dlink and USR. The problem with 2.4 Ghz is a microwave oven can kill your connection. Otherwise it works fine for me for home use.
The consumer grade routers most popular for VoIP including wireless are Linksys brand. Lots of threads you can find searching on QOS in this forum.
Not much discussion here about commercial grade routers and APs.
Note some providers like Vonage offer a wireless Linksys router with built-in VoIP Telephone Adapter (TA). They should be usable connecting to another host router.

| Go for 802.11A access points. they cost more than their G counterpart, but yuou will appreciate the once you know the hassels you avoided. 11A offers about 14 non overlapping channels, meaning, 14 of the access points can sit next to each other and cause NO interference at all...
I recommend .11a for these kind of situation..
Other than that... you would do just fine with wireless lan and VOIP...
Where as 802.11B/G has only 3 non overlapping channels... you plan tot have 4 wirelss bridges, means, you can have only three without interference in a close proximity..Even if you have 3, your boxes will experience interferece from 2.4Ghz phones, your neighbor's access points etc.. |

Washington, DC | Thanks. As I do not have any experience woth wireless LANs, I did not think about limitations in terms of channels and intereference. I guess I might be better off just going with wired connections. |

| We had the same situation when we moved into our office. We use the wall plug ethernet bridge by netgear for 3 of our office computers and 2 of our VOIP phones and 1 of our network printers. They are very easy to setup and use.

Washington, DC | Thanks. I had not thought about the possibility of ethernet over power lines. The only problems is that it is slow, but this is certainly an easy solution from the installation perspective! |

Myrtle Beach, SC | The speed is great for internet access. We notice it is slow when we are transfering huge files between computers. We do not transfer large files often. The speed is 14 mbps. |
