We've never had a good experience with venue WiFi. More often than not it's a disaster. It's ruined our events and lost us customers. We figured it was about time to do something about it, so we built our own.
We call our solution "WiFi Bro". It's a nod to our Northland home and a reflection of our Kiwi ingenuity. Inside the military-spec Pelican case is an enterprise-grade long-range WiFi access point coupled with a 4G router with antennae to boost signal strength.
We've tested this all over New Zealand, we even use it ourselves when we're supporting events. We can dial-in remotely to configure the WiFi exactly as you need it. Provided you have cellular coverage and mains power you're sorted.
Pay for what you use. Basic and Business packages support up to 50 users at ADSL/VDSL speeds. Custom packages can support hundreds of users.
