Video Sender / Wireless Lan
 

Hi,

This is a long shot, but has anyone used a wireless video sender in the same house as wireless Lan?

My wireless router operates on 2.4 Ghz which afaik is the same as most video senders. Does anyone know of one that operates on another frequency?

Cheers,

Steve.

You can do it. I do.
There are 4 channels on the video senders. There are 13 channels on the LAN senders. The channels involved are not the same, one video channel overlaps with 3 or 4 LAN channels.
You need to play a bit with them, but the two can co-exist.

I usemine mainly to filter out carol singers and trick or treaters. So not used for much of the year.

EDIT : I'm not just a grumpy old man, I object to groups of 13 or 14 year old lads turning up at my door expecting money for their half hearted attempts.

Yep 'proppin' is right

However there may also be other peoples 'kit' in range of yours as well which could lead to some potential problems but certainly 2 different divices in the 2.4ghz range should be able to work togeather.

Its probably worth pointing out that bluetooth also operates in thsi frequancy band.

Yeah, right! ;)

'I don't believe it'. There's no resemblance!!! We even sound different.

You never know do you :D

Slightly less off topic, showing my naivety here, what's a video sender?

Re: Video Sender / Wireless Lan
 

a video sender is as the name suggest - a device that sends video (over a wirless link in this case)

that is you can 'send' the output of say a vidoe recorder in one room to a TV in another

HTH

I believe there are actually 13 wireless LAN channels in the UK, but most equipment doesn't let you select >11.
Those channels overlap as well, so you cannot use adjacent channels - some say that 1, 6, 11 (USA spec) are the only usable channels - if things are tight, try to get at least 2 channels away from an occupied one. And that is really too close even then - If you only have a 1-11 channel selection, setting the videosender to it's highest may move it above 11.

1, 4, 7, 11 is a compromise 4 channel usage, but range will be degraded - but if 1, 6 and 11 are all in use, try to persuade whoever is using 6 to move to 7, as if you slot into 4, it'll hurt their performance less than if they stay on 6.

Channel 9 and adjacent suffer severely/moderately from Microwave oven interference.

The usual default is 11, it seems.

Basically, if you have a video sender on a low channel, set yopur Wifi to a high one, or the reverse.

It can be done, but there isn't much room for anything else in the locality ... a neighbouring WiFi network or video sender will leave you struggling to fit an additional device into the channel allocation.

I have 2x Wireless Routers (linksys & trendnet), 2x DigiSenders by AEI and 1x Philips baby monitors and they all work fine together except that if I turn on SSID broadcast on the Linksys router I get a funny click on the TV and a interferance bar going up the screen every 2 seconds or so!

BTW the Digisender receiver is actually sat on top of my Trendnet Router!

Re: Video Sender / Wireless Lan
 

Interesting... what's your channel bandplan ... you would appear to have assimilated the entire 2.4GHz ISM band locally!

Re: Video Sender / Wireless Lan
 

Never having used a video sender, is it possible for you to have the same type as a near neighbour and for you to pick up the channel they are watching on yours. What sort of range do they work over and have an effect on other equipment?

Re: Video Sender / Wireless Lan
 

Very helpful reply, Matt. Thanks. Definitely worth trying once I get my NTL digital upgrade (but don't tell NTL :shocked: ).

Steve.

Re: Video Sender / Wireless Lan
 

Yes you can pick up your neighbours signal and I often do! (my devices use four channels and channel 3 lets me watch what they are! - albeit the signal drops and the sound is terrible).

With regards to range the AEI ones have various options that I believe will allow a 5km (yes km) transmission! - Don't think you can buy this kit at Argos though!

Re: Video Sender / Wireless Lan
 

I suppose you could use a Pringles tin antenna on a video sender, if you wanted extreme range!

Reminds me.... What's the best way to set the diversity antennae on the average router? - the Laptop (internal WiFi) upstairs gets from 60% to 80% signal strength/quality. with the Router antennae vertical/splayed.

I'm thinking more horizontal polarization is needed, and laying them flat, one out, one across may work better (they have an adjustable elbow, and turn on the mounts, so they can go in any direction)

Re: Video Sender / Wireless Lan
 

The wireless transmitters are licence free and are limited on transmit power. The 5km will be in very quiet areas and using very directional aerials (maplin do the aerials).
