An unforeseen problem with distributed audio
Posted by: gone on 12 June 2010
Despite all this fascinating talk about dither and jitter, I found a fundamental problem with distributed audio last night.
While relaxing with a glass of red and listening to some toons, my neighbour decided to start mowing his lawn, with what sounds like a badly serviced Mountfield.
End of wireless LAN, end of music
I guess it's some horrible interference caused by a broken suppressor in the lawn mower (discussions will ensure later today, but it buggers up the football on telly as well)
This highlights the downside of having yer music upstairs and not an a physical medium. At least I had the vinyl fallback position.
As we become more dependent on stuff being networked around the house, I wonder where this is going re: mission/life-critical systems

I know what you mean. The internet has been down here for 12+ hours on two occasions in the last couple of months. I felt cut off from the worldquote:Originally posted by Nero:

My suggestion would be to see if you can get your network setup wired instead of wireless. It will improve stability on all accounts.
One other thing you might consider is to use a wireless network that operates on the 5 GHz band instead of the more commonly used 2.4 GHz band. That might move it outside of the interference caused by many household machines and other local wireless networks. It also has some drawbacks though:
- not all WiFi devices have inbuild antennas that operate in this band so you might have to setup bridges to those devices that don't.
It would require either a Dual Band Access Point or a dedicated 5 GHz access point / bridge.
The 802.11n standard supports both the 5GHz and 2.4 GHz band.
802.11g devices, like the Uniti, only support the 2.4 GHz band.
Not all devices that use 802.11n support both 5 GHz and 2.4 GHz, some/most only support 2.4 GHz.
Complex business this wireless networking.
My advise would be tye to get it wired instead of wireless.
