Is a 1/4 a rough estimate or has someone been able to test E at 3.65GHz? What type of range have people seen in the field with E at 3.65GHz with indoor subscriber units?
I would a agree that a 1/4 mile in rural area of Colorado or Iowa (where I grew up) is not very useful but now I live in a reasonably dense urban area. A 1/4 of a mile is small but if I can do mobile WiMAX at up to 1 mile, then the economics work.
