The idea of Meraki Minis' are to start a network somewhere. The size and purpose of the network is completely up to you. Maybe you can add them to a public library in town that doesn't have WiFi. Or you could give one to a neighbour and share your monthly internet bill. Or sprinkle a few around the building, turn on billing, and become your own ISP!

Approximate range: Barring physical obstruction and radio interference, Meraki access points equipped with omnidirectional antennas typically reach 100 meters. Directional antennas (sometimes called "panel antennas") greatly extend range by concentrating power in a single direction. With line-of-sight and limited interference these links are known to reach 20 kilometers or more.

Wireless clients: 1 wired access point to the router(ADSL modem) and upto 10 wireless (mesh) access points linked to it.

A single Meraki gateway Access Point can work with many non-gateway APs and many users. A recommended maximum number of wireless APs to associate with a single wired gateway AP is about 10. The maximum number of users will be primarily constrained by available bandwidth.

Meraki suggests that you not place APs more than 3 wireless "hops" away from the gateway AP. This can affect the quality of the connection that users experience.

Access policy: You can create access policies for each point at http://dashboard.meraki.com (Merak is a cloud based solution)

I hope this helps. Let me know if you have any more questions or feedback.
