Noob: "Touchscreen over Wifi-TCP/IP?"

[Neurorad]

Very hard to search for the term 'TCP/IP'. <_<

Too few letters in the search term(s)!

What are the problems with wireless touchscreens? If anyone could give me some direction, I'd greatly appreciate it.

Thanks so much.

There are no problems with wireless touchscreens unless you are out of range of the signals.

Hey, thanks buddy.


Do I run 2 wireless networks, 1 dedicated to HA? Might be simpler than mixing.

I guess it depends on the situation. If you are trying to send out HD video over wireless signals to other parts of the network, then having a separate wireless network for the touchscreen would probably be a good idea. That is only because the wireles HD is going to suck up so much bandwidth. But if you are just doing normal activites (like surfing the internet, etc) on the network, then I would bet adding a couple of wireless touchscreens wouldn't be an issue.

The best thing to do is probably just try to combine the devices to your current set up and see if they work well. If the network traffic is too high, then you can always buy the equipment to create a separate wireless network.

I also think that most wireless devices are going to have the G protocal built in. So there probably isn't a big need to buy Draft-N stuff for the touchscreens. Again, if you are trying to serve HD files, then Draft-N is going to be required. Then it would make sense to put the touchscreens on their own G network IMHO.

also really depends on the quality of your access point - some can only handle one to two devices worth of bandwidth, while other higher-end ones have a good enough throughput to support 25 or more devices worth of bandwidth.

I have 10 wireless devices without any problems. Just make sure your access point supports QoS (Quality of Service) so that videos, VoIP, and plain old web browsing are prioritized. Most mid to high level access points have this nowadays. I'd recommend D-Link or Netgear but not Linksys. Linksys is owned by Cisco, and they tend to NOT put high-end features in their mid-level access points, because....they want you to buy their very expensive Cisco access points to get these features. D-Link and Netgear don't have these same hangups about high-end features in an AP costing $60.

Another option is to get a high-end access point with 802.11n at both 2.4GHZ and 5.8GHz. You can run your video at 5.8 GHz and low proprietary stuff at 2.4GHz. Probably overkill, but its there if you need it.

Thanks for the FANTASTIC points.

I didn't even know about QoS! I've been looking at Linksys G access points, unaware of QoS.

With all the discussion of keeping automation software on a separate, dedicated PC/server, I didn't know if I'd need a separate network also.

I'm trying to learn everything I can about HA, and putting together a system over the next several years (well, I'm sure it will never really be 'completed').

I don't have any access points, or touchscreens, now, but I'm trying to think ahead.

Forums are a tremendous source of info (AVS, CQC, HomeSeer, SmartHome), and I've already spent hundreds of hours reading online, but I wish there were more focused sources, like books (very few [recent] out there).

or you can buy certain linksys routers and reflash with free alternate firmware tomato ( http://www.polarcloud.com/tomato ). QOS how to on tomato - http://www.decimation.com/markw/2007/10/03/tomato-qos-setup
