Wardrivers may have seen Wi-Fi access points Bolsena, Maggiore, Panarea and Stromboli (They are actually in all capitals but I cannot bear to reproduce shouting.) pop up together on their machines. The explanation is that they are all in one box on a Marks and Spencer site. More recently I have seen other Italy-related names replace some of those on the list. When the site offers public Wi-Fi, one of the names will be replaced by the public access. Previous text from 2014 Jan 02: I have seen these four in various places, most recently at the Blyth services on the A1 near Doncaster. The highly recommended Wi-Fi Analyzer app tells me:

• they are all on the same Wi-Fi channel
• they all have the same signal strength
• they are all from a box made by "Symbol TechnologiesWholly owned Subsidiary of Motorola"
• they have consecutive IP addresses - in this case 00:15:70:7B:28:28 through ... :2B.

From this we can confidently conclude that all four of these access points are located in the same box. Multiple logical access points in one box are not unusual - standard BT wireless routers all offer three different names. On the basis of the Wikipedia article about Symbol Technologies, I suggest that these access points are in a supermarket or similar and are there to allow hand-held barcode scanners to communicate back to their base. The four different names enable different departments to have independent communication channels. All four names are geographical features of Italy: Bolsena and Maggiore are lakes. Panarea and Stromboli are adjacent islands though the latter is better known as a volcano which is effectively the entire island. (This page reports seeing "Symbol TechnologiesWholly owned Subsidiary of Motorola" providing WLANFRIENDSHOUSE but when I looked on 2014 Jan 13, I could not see it.)
