Nomadix backs up Hughes:Hughes Network Systems is building Wi-Fi networks in "leisure HotSpots," which means RV parks and marinas, using satellite links for backhaul. The network uses Nomadix on the backend so that users don't have to re-subscribe each time they roll into a new location. This should be a cool service for folks on the road and they may find that the probably slow service is better than nothing.
Reports from RVers indicate that bandwidth is generally scarce at parks, and the folks travelling -- no matter their age -- are actually heavy email and cell phone users. Providing enough bandwidth at these location is an actual problem needing a solution, not just a marketing machine message.
