Ralph, To answer your question regarding what part of "workforce" is using the 4.9 GHz. The short answer is the "city first responders workforce" will be the primary user of the 4.9 GHz portion of the Mesh networking. The 2.4 GHz will be used for "utility services" such as metering/monitoring. The electric meters have a "WiFi chipset" inside the utility meter (802.11g flavor).
The longer answer is that some cities also have electric utilities (municipalities). The CIO thus asked his Communications Director to file for the 4.9GHZ FCC license for the 4.9 GHz portion needed. The "radio" we used was by the major manufacturer and actually is 4 radios in one box. (2) 2.4 GHz radios + (2) 4.9 GHz radios (Mesh). We connected the mesh radios to a 900 MHz radio and backhauled it to the City corporation yard on 5.7 GHz if I recall (or it could have been all 900 MHz, I need to check my notes) We used the 900 MHz because the of the amount of trees in the area. And the backhaul was only about 2 miles from our system. We backhauled to the fiber POP at the Corporation yard. All the backend network equipment was Cisco so we very closely with the client's Cisco architect (network manager). He set up all this outside his "firewall" and indigenous city system. Sorry for not answering you earlier.
