The Wisconsin city has a booster group that will hand out Wi-Fi decals for local shops: Spirit of Milwaukee will provide businesses with decals that identify them as Wi-Fi hotspots extending an earlier campaign by the non-profit cultural group to identify high-tech businesses with a blue light. (K-Mart, move over?) It's an interesting idea to establish a local brand for Wi-Fi availability: because each location will have different bandwidth and network quality, prices (from fee to yow-ee), and expectations (make a purchase, use the network), it might raise the right expectation in users. But it certainly will help local residents and frequent business travelers better know where to unplug in.
