1 Property of CostQuest Associates and the State of Wyoming Wyoming Telecommunications Council Targeting Wireless Internet Services at Areas with Lower Investment Thresholds

2 Objectives Identify current broadband gap areas with potentially low cost for wireless broadband service Use data from 9/2005 study (investment, broadband service areas) Use conservative deployment practices based upon Motorola Canopy directives Predict number of potential, served customers in selected areas Use public data for analysis wherever possible 2

3 Fixed Wireless Architecture 3

4 Wireless Engineering Inputs Key Inputs 10miles Design distance for access 20miles Max distance for access (can be increased to 40 with placement of repeater antenna within 20 miles) 20miles Design distance for Backhaul hops 70miles Max distance for Backhaul hops 3 Access frequencies used (distance dependent) 5.7GHz, 2.4GHz, 900Mhz 5.7GHz Frequency used for Backhaul Antenna Placed at each house provides Ethernet connection EAR/IP Availability assumed 200 Max line count on an antenna 60º Coverage arc of per antenna 20% Discount over vendor list price Priority State owned towers given highest priority in Customer assignment Cellular lowest 4

13 Predicting Wireless Coverage Although the Motorola Canopy Solution offers both a LOS (Line of Sight) and NLOS (Non Line of Sight) options, this analysis is carried out using LOS viewsheds Use actual tower height (AGL Above Ground Level) and 15 mi max radius Receiver height is assumed at 15 AGL Terrain data is from USGS National Elevation Dataset (30m) Full state is not available at 10m Aerial Photos (DOQs) are 1m from USGS Terrain analysis through Global Mapper 13

22 Determine Potential Customers Who Fall In Viewshed This represents 1310 potential customers within 15mi of tower. The count includes Rawlins which is a broadband served area. 269 Potential Customers Fall into this viewshed 22

23 BGA Potential Customers in Sinclair only Sinclair CDP only (BGA) customers are about 211 potential housing units. 23

24 Potential Service Areas Near Sheridan This is particularly challenging area due to the terrain. 24

25 BGA Potential Customers In Story, Wyoming 25

26 Potential Customers In Viewshed There are 658 potential non-served customers in the viewshed of this tower located within Story,WY 26
