Thanks for looking into it for me, if anyone has something like this (or similar to sell) I'd be interested. 200m is optimal, but I can deal with much less coverage as I am budget constrained.
Being budget constrained isn't really an option here if you want something that will work. That being the case my recommondation would be something like a 2nd hand Ruckus 7762S - you'll get one landed in NZ for probably NZ$400ish
Thanks will look into it. 200m is the optimum but obviously is the budget doesn't stretch that far, then I will work with what I can get within budget.
That was my low budget option!
