"5G Wireless uses its new cellular-style Wi-Fi base stations to create a broad service area with non-line-of-sight (NLOS) capabilities. These enhancements are compatible with standard IEEE 802.11b/g Wi-Fi equipment. The 5G Wi-Fi Hotzones(TM) function through macro-cell base stations deployed from tall towers and the tops of tall buildings, while dead spots are filled in with smaller micro cells following the proven deployment strategy used today by the cellular carriers."
Which means that they are not saying they can get 10km range from
one base station, but from using one main base station and
many smaller base stations.
So - to be honest.. that's not all that special or new.
Unless you know they are doing something different from the press release?
You will struggle to cover 1km with just the one base station connecting to laptops unless you use multiple base stations - perhaps with WDS. Something Mikrotik can do easily at very little cost
Again, choosing between sector'ed aerials or omni's is not just about range.
When putting in hotspots (for genuine commercial profit), you either have to find one person who is skilled in mechanics, radio, electronics, networking, servers and websites (to find one person who can do all that is rare) or more likely a team of people. Oh, and someone who's not afraid of working (safely of course) at heights!
All this costs money and skill. The number of WISPs that I've seen go broke - all because they think it's really easy to make a fortune from this game and it simply isn't.
As I often say, "If this business was that easy - anyone could do it"!
So, if you want to install a Mikrotik based wireless hotspot in your area, sure, go for it, but I strongly urge you to find your nearest Mikrotik Consultant and speak with them first before spending too much money. Although looking at the list, there does not appear to be anyone
that close to you.
