Utilizing the ever-growing and improving Mobile Phone data networks available in North America our true Network RTK corrections consume less than 2 GB per month with heavy usage. For areas outside cellular data coverage, options include: 1. purchase an electronic “Bridge for RTK” which bridges traditional UHF radios to the Cellular data network, or 2. Use our dual technology direct IP modem which runs on both GSM and CDMA simultaneously combining the coverage of two major carriers such as AT&T (GSM) and Verizon (CDMA) for maximum uptime.
