- They want to support billing - which requires network access, at least for the station itself
- They want to minimize the cost of the station both up front and maintenance. Fewer cables and accessories (eg, card readers) helps a lot here
- Much of their target audience is inside of parking garages where cell reception can be spotty. This means mesh is a must and bluetooth for client connectivity is best.
- They need to have power metering built-in and there are related regulatory concerns due to usage based billing
All of this means that it can't be a truly dumb device. What they've come up with is essentially the lowest cost solution that can possibly work.
Hey guys, this thing is "green". Well, we couldn't actually paint it green, so it's blue, but that's as close as we could get it!
