 We are in the process of expanding the WiMAX coverage around the greater Madison area.  Initial propagation models have been created by Tony Kapella and a colleague of his to show the minimum signal strengths in and around the city.
+==== Propagation Models ====
+Estimated coverage plot of WiNEST in conjunction with the 5NINES 5M network in the downtown Madison area. Speeds of 30 to 15 mbits should be possible in the green areas, orange should be approximately 14 to 8 Mbits/s, and red areas will likely provide approximately 7 to 1 Mbits/s.
+The predictions include ground clutter data, building height extrusions, and other hacks to get the urban environment loss 'right.' Predicted downlink receive levels assume a 0 dB gain CPE antenna, 2500 mhz frequency, non-mobile, and +55 dBmw EIRP at the cell site. This is what one could call a "conservative" estimate of coverage (no mimo recovery, stc/ctc, or other gain is assumed).
+Color scale, units in dBmw:
+  * -85 or better, green
+  * -90 to -86, orange
+  * -95 to -91, red
+  * <nowiki><=</nowiki> -96, no color
