The 5Ghz frequency for wifi is primarily for faster data rates at a shorter physical distance. The shorter wave-length used by the 5Ghz band makes it less able to penetrate walls and solid objects. To optimize cost and how effective the Roadlink router is at sending your Wi-fi signal into the RV, the Roadlink C2 only features the 2.4Ghz band. Additionally, the data rates of 4G service are slower than the capability of the 2.4Ghz band, so there’s only marginal benefit to the 5Ghz band for data speed when 2.4Ghz band is congested, which is less common in non-metropolitan areas.
Why does the Roadlink C2 use 2.4 Ghz?
