The problem with OLSR, and it is even stated on the Wikipedia page, is that when you push routing tables to every device, it creates a load on the system. If you have a few nodes its not an issue, but when you are pushing routing tables for 250+ nodes, you wanna make sure that the system can handle

Most SCADA radios, are MDS 900 mhz radios. They are connected via an RS232 connection. There are companies that sell RS232 to ethernet adapters. That would be the most cost effective way to do that. Blackbox is one company that comes to mind right now. www.dslbyair.com --- Ray & Jean <[EMAIL PROTE
