Hi,
My name is Shawn Kilburn and I'm the Meridian team's technical writer. I thought I'd jump in and answer your most recent questions.
1. Simply put, you don't need access points to use Aruba Beacons for location services and notifications. If you only have battery-powered Beacons, you can deploy them using the Aruba Beacons app (iOS-only). APs and controllers are necessary for the Meridian Editor's Beacons Management feature, but that's it.
2. The Meridian Editor includes a Reports feature that tracks things like the number of users using your Meridian-powered app, how many notifications were received, what search terms were used, and what routes were followed. This is done on the Meridian-powered app client side, so APs and controllers are not necessary.
Cheers,
Shawn
