Fixed Wireless technology does have some restrictions such as distance from the PSC Wireless Point-of-Presence and “line of sight” requirements. Specific distances and actual mileage from our Point-of-Presence will vary due to local conditions (hills, buildings and other obstructions). Due to such conditions, PSC must conduct a Site Survey of the customer requested location for service. Once complete, the PSC technician conducting the survey will leave the results at your location.
