A deal to integrate Boingo Wireless's authentication system into Wificom's hotspot management and billing software opens Boingo to more WISPs: Adding Boingo roaming could be as easy as checking a box for wireless ISPs using Wificom's SAB Server. The release notes a Brazilian WISP with 167 hotspots just flipped that switch. This should allow Boingo easier penetration of markets scattered worldwide. The SAB server manages authentication, billing, and other features needed by WISPs.
