ion dollars worth of revenue over the next 4 years from that system. The reason I use this example is because the techniques we learned became the foundation for almost every future system.

There was a book written called “All I really need to know I learned in Kindergarten” written by Robert Fulghum. We found that the Stratosphere was our Kindergarten. The VDSL units we used later saved another client $100,000 in their initial installation. The roaming spammers gave us the opportunity to test various methods of blocking them and handling high volumes of traffic. Hackers scanning through the system forced us to micromanage connectivity and to be proactive instead of reactive. The system was later upgraded to go from 200 simultaneous users to over 1000 over the next few years by simply adding more radios and VDSL entry points.
The main problem with large scale Wi-Fi systems

This is also where we learned the hard lesson as to what we believe caused many of the problems of future industry municipal systems. Our APs were 200mw. Our antennas were directional and approximately 12dBi. Laptops are 30-100mw.

Because we couldn’t get approval to bring in more access points, there were some areas where clients could see the wireless signal, but couldn’t connect. They weren’t happy. Before I get hammered on why we didn’t have closer access points, the first radios that went in were at the end of the halls for coverage and backhaul. We were going to add additional radios later to cover poor signal areas but a change in ma
