Re: [Wlug] Speech recognition software

Hi Andy, What sort of requirements do you have. Does the voice recognition system need to be locally resident or can the "recognition" part be sent off to a server. This determines the local resource requirements. For local processing you need lots of memory and a ghz processor. Remote recognition leaves you at the whim of the service - think samsung tv or google's data collection. What sort of response times do you need? That is, how many seconds between uttering the voice and receiving a response. Do you need single word recognition, phrase recognition or whole sentence recognition? -David On 02/21/2015 08:05 AM, Andy Stewart wrote: > HI everybody, > > Do any of you have experience or recommendations with any Free Software > that does speech recognition? > > Thanks, > > Andy >

Re: [Wlug] Wireless mesh network question

by Randall Mason

Every access point on the same channel (as well as every client) shares bandwidth. If all of the networking is happening on channel one, with two clients, you would end up with 1/6 the bandwidth. The problem isn't interference, it's making a 6 lane highway a two lane road. If you use distinct, but overlapping channels, you end up with radio level interference, so not shared bandwidth, but lots of retransmits when both are active. The best case is using the non overlapping channels which allows you full bandwidth and very low interference. So I would have your backbone on some far channel from your clients, or your chatty mesh protocol will slow the normal clients to a crawl. You could even use the three distinct channels so that one is backbone and the other two are not overlapping where the two circles fall in the same territory.

Re: [Wlug] Wireless mesh network question

by Frank Sweetser

As long as all of the APs are on either matching or non-overlapping channels, you should be fine. In practice, this means you'll get the best overall throughput by evenly distributing them across channels 1, 6, and 11. You *might* be able to get away with channel 14 (this is outside of the normal part 15 regs, but you can probably legally get away with it since you're licensed), but you may have strange results if you're trying to have standard wifi clients connecting to them, as some of them are set up only for US options and won't look at that channel at all.

HI gang, I setup an experiment with all of the wifi access on one channel. WiCD saw both access points with the same SSID and wifi channel. Connecting to either of them seems to have no ill effects.

Wireless mesh network question

by Andy Stewart

HI guys, I am planning to setup a wireless mesh network at a ham radio event in June. Each mesh node will consist of two Linksys WRT54GLs, much like the demo I showed at a recent WLUG meeting. One of the WRT54GLs will be on channel 6 and carry mesh network traffic. The other one will be on channel 1 and allow generic wifi devices access to the mesh network. It seems like there would be an interference problem if every node allowed wifi access on channel 1. Should this be 4 different wifi channels? It is possible for a user to be within radio range of multiple of them simultaneously. Thoughts? I've never setup a wireless network before and could use your advice. These mesh nodes will be placed outside in weatherproof enclosures with battery power. Thanks!

Reminder! Meeting tomorrow! Feb. 12th 2015 at 7pm (Mid-Century Room) rm 331!

by Tim Keller

Hey Everybody, This is just a quick reminder that we're having a meeting tomorrow at 7pm in the Mid-Century Room (rm 331) in the student center. Andy is going to be giving a talk about mesh networking! Afterwards we'll do pizza at Tech! Refreshments will be provided at the meeting as well. Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".
