Cisco Meraki location analytics: what you get built in and where it stops
You will be able to decide which Meraki presence questions the built-in dashboard can answer, when to stream raw observations through the scanning API, and when you need a captive portal for identified visitors. You will also know why loyalty figures mislead, and which figures you can safely put in front of your board.
