A campground WiFi system typically operates several Access Points (AP) throughout the park. Depending on the design of the WiFi system there can be a considerable distance from any particular RV site to the nearest AP. Successfully connecting to the WiFi network involves both receiving a signal from the AP as well as returning a signal from your network to the AP. Laptops, tablets, etc, typically have very low power ( a few milliwatts-mW) WiFi transmitters to maximize battery life and their built-in antennas are small and not particularly effective. In comparison, a WiFiRanger Elite has a 1,000 mW transmitter with an advanced antenna that, itself, provides a substantial improvement in both receiving and transmitting WiFi signals.
Furthermore, from a security perspective, the Ranger protects all communication inside your network using state-of-the-art WPA2 encryption. Even if your campground WiFi doesn’t use encryption, you can use your Ranger’s SafeSurfTM feature to create a VPN “conduit” which protects your data against nearly all common attack methods.
