Although there isn't a master database that catalogs all the communication towers in the metro area it wasn't difficult for me to find them. Using aerial images together with knowledge of the metro from almost 40 years of living and working in this area I was able to compile a map that shows the wireless coverage in Roseville. In the metro we have only 5 major service providers; Sprint, Nextel, Verizon, T-Mobile, and AT&T. Sprint and Nextel are a single company but use tow different technologies so therefore have dual installs on most towers. Keep in mind that not all providers are located on every tower so the map is not indicative of the complete RF coverage for Roseville. Additionally the service area from a tower has been generalized to a radius of 1 mile. Some towers provide better coverage depending on height and the provider equipment. But short of an RF inapping of the signal level, service providers will typically use the 1 mile radius for towers and less for roof top installations on 3 story buildings. So lool<ing at the map you will find red circles (Roseville owned communication towers), black circles (towers owned by others), small blue circles (representing known roof top deployments), and a yellow circle (representing Acorn Park service area). Absent the yellow circle you can definitely see a dead zone extending along Dale Street north to County Road C then northwest across Lake Owasso and into the vicinity of Victoria/County Road D. I have received comments/complaints from residents in this neighborhood that have trouble with their mobile phones. I did notice from the map that the area south of Acorn Park should be covered by two towers located in Little Canada along Highway 36 near Rice Street. However if you visit these towers you will find shorter 100' free standing towers and given the ground elevation into Roseville (it's all uphill) and the heavily wooded neighborhoods it could be understood why Acorn Park residents commented on poor coverage as well. I would suspect that a tower in Little Canada adjacent to Rice Street at Owasso Boulevard provides most of the coverage for the northeastern part of Roseville. This tower is 180' tall and hosts a number of providers. Taking into account this tower with its proximity to Acorn Park it is evident the value of another 150' tower in the Acorn Park area. In the discovery process I found quite a number of single provider towers at 100' in height. This is why there are so many towers along the I35W corridor. I guess in the industrial areas almost anyone can put up a tower in their parking lot and rent it out.
