Broadband

[TheDon]

The distance is really not going to be a problem. On 2.4ghz using a cantenna you can do a mile no problems (I've personally done a cantenna link of over 500m) 100m isn't going to be any sort of problem.

I never said the distance would be a problem, deep space probes leaving the solarsystem use just 20w to transmit backj to earth. What I suggested is that 2.4 is more susceptable to interference (mainly due to sharing the band with a million and one devices that are unlicenced and tend to give out a lot of sproggies (technical talk ))

Well you said over that distance interference would be a problem, my point is that it's rarely a problem over such small distances. If you can't get a full signal over 100m with a cantenna setup you've done something wrong.

One of the benefits of cantennas as well is it's trivial to adjust the polarisation of the signal (you literally just have to rotate the cantenna) so even if you are experiencing interference a quick rotate and you'll likely eliminate it.

Sorry to hijack this thread - I have a question!

I've got a bit of CAT5e running from a faceplate on the study wall; up the inside of the palsterboard; into the loft and then out through the eves of the roof, down the side of the house and into a hole in the wall, into the lounge and terminated with an RJ45.

I assume this is also susceptible to lightning and the such. I suppose it would be a good idea to remove the patch from the patch point and the RJ45 from the switch during a storm?!

The barn is about 90 mts from the house and the only way i can get to it from the house is suspended overhead.

Can i use the external 4 pair BT cable and if so do i connect it using rj45 plugs

thanks

My first thought was to get a Netgear WNDR3700 router. This has dual band wireless, including 5 GHz which is rarely used domestically. The 2.4GHz band tests well up to 350 feet. That covers your 90 metres. The 5GHz band is weaker on 300 feet, but you get less interference on that because most other router s don't use 5GHz. If you have any trouble you can get a signal booster.
These solutions sound a lot less work than digging trenches and laying trunking.

Retails for £120 at Amazon

Sorry to be a pain but can someone give me their comments on the equipment listed above. i just need to know whether its worth buying a pair of these.

Thanks so much for you advice

[Kymmy]

I'm confused here?? You're setting up for a client a network that you have no idea about?? You don't understand the specs of the bridge youve specified and you don't even understand the very simplistic limitations of ADSL, CAT5/6..

So why are you doing it??

Well actually this is the situation.

I run a Security Company and I have a customer who wants CCTV put into their barn so that they can watch the cows from their house.

The barn is about 90 metres from the house and the options are:

Run the CCTV cable from the barn to the house which means they will only be able to view from the house.

or:

Have broadband extended into the barn which means they will be able to connect the DVR to the internet and be able to log in and view from anywhere.

All i need to know is if the kit I have listed is good enough to do the job, if so I will get it all installed and contact a boffin to do all the technical stuff.

I hope I aint upset anyone but I've always said If you don't ask, you won't Know.

Would've been nice for the guy to get a welcoming, understanding and non-patronising response! He is here because there are things he doesn't understand. He does security, not networks.

I guess because you do security, you have access to lots of info on security cameras. Anyway here are some wireless surveillance cams that might be what you need for the barn end of your clients set up.

[Kymmy]

Then why is he sorting it out himself, if he's gonna get a "boffin" to do install then why doesn;t his "boffin" advise on the equipment due to his "boffin" being able to do a site survey that we can not.

OK here's my answers to his questions.

1# As an ex-IT professional I can not answer the question without a site survey
2# As a forum user I suppose they will do

My "attitude" is that if he's doing the job for a client then he should have been asking a professional around to do the job properly without asking on a forum

You know, its people like you that screw up this world. I've always been taught that if you can help someone then do so.

As an "ex-IT professional", it should not take you 2 minutes to help me out but oh no !!! its too much bother.

My "boffin" is sorting out his mums funeral at the moment so I didn't really think it was suitable to ask his advice but you know after reading your thread I think I'l give him a call.

I'm so sorry to have bothered you.

[Kymmy]

Yep, after a site survey you are perfectly correct that it would take me 2 minutes to say definately yes or no.

As for screwing the world up well that's down to the whole human race but thanks for appreciating my part in it all

You don't seem to understand that you're asking a technical question based on so extremely few facts and when asked for the facts you've shown that you understand very little based on what you are trying to do. As such if anyone says to you "YES THOSE BRIDGES WILL DO" they're actually talking out of you know where as you have not given enough info. If you are a professional cctv installer then you should appreciate that you can't give a quote over the phone or even specify that the job can/can't be done until you've seen the place
