Internet from Cellular and WiFi can vary based on the service provided. We tend to say, “You are only as good as What you are Connected to.” With Cellular, we are capable of up to LTE-Advanced. Speeds published for LTE-A (and WiFi, for that matter) are Theoretical Max. You rarely get Theoretical Max. Our WiFi products have different WiFi technology levels. Rogue Wave products go up to 802.11n (WiFi 4), and Professional Series products go up to 802.11ac (WiFi 5). A marina or other Hotspot will not give you their full bandwidth/speed; whatever that speed is, it’s a shared system. WiFi and Router hops – it is all about division. Every router and WiFi hop loses some speed. More devices connecting to an internal wireless network will cause sharing/division of available bandwidth/speed. Our products don’t limit speed, in general, so if you have an issue with the speed, you may want to contact us for support. There is not an exact number for a given connection. Our products can handle speeds surpassing what you will be provided by most Internet connections. But like we have been saying, your marina probably will not give you the speed our products offer.
