I hear what Chrys is saying, but I think wireless will hit a wall, for another techno analogy: just as single CPU cores are doing now. Also there will always be the problem that wireless is a shared medium, with all the resultant unpredictability of it. If you have a greedy neighbour appearing suddenly and never going away, then you are stuffed, but you’re still paying the same amount for a fraction of the service you used to enjoy. That’s why I would never be interested apart from in conjunction with something fixed; I want something that I can rely on, and I’m interested in the worst possible case. Business users I would think should be using fibre, which has enormous potential for future-proof growth, especially if ducted I suppose. I don’t know if very wideband fibre has problems associated with it, but I’m assuming it’s fair to say that the growth potential is practically unlimited at the moment for the foreseeable future at least.
