Meraki

If you're tired of waiting for your favorite bar or park to get Wi-Fi, do something about it and build a long-distance wireless network yourself. Using advanced mesh routing technology to increase range and network capacity, the Meraki Mini ($50) and Meraki Outdoor ($100) can extend your personal internet connection as far as you want, depending on how many of the repeaters you buy. Your connection can be shared with thousands of other laptop-toters for free, or kept private. If you're a wantrepreneur, you'll need to order the Pro Editons of the Meraki Mini ($150) and Meraki Outdoor ($200), which offer features for user management and billing.
