I am trying to set-up a small network that will enable internet access into an external building about 90m away. However I would prefer access throughout the business area (being a farm, we would be able to access to the network from mobile devices then), which would be up to 150m but if this will be costly then there is no point. Meaning that the antenna should also be omni-directional.
There will be a total of 5 users maximum on this part of the network, so there should be no need for expensive equipment. There will also be little interference in terms of building work, as the antenna will be mounted outside to avoid the granite walls from our main building.
I have just ordered a new Netgear DGND3700 for our main router to handle requests, I am unsure if this will make any difference to what else I should buy?
So this leads me with the question, is there anything I should look for in the wireless access point and antenna? Or are there any antennas in-particular I should be looking to buy?
Please note this must be wireless, as if I were to wire the internet access it would be about 130m in cable and would work out far more expensive and we would still look to fit a wireless network in 2-3 years time.
