Wireless Internet with NapaNet View our Wireless Information Center Sign Up For Wireless Service Wireless, is another transport vehicle we use to reach customers that need high-speed broadband services beyond conventional DSL distance restraints. To meet the request and service demands of our customers, Napanet is investing in this "RF" (Radio Frequency) technology. Our product of choice is a very secure, heavily-encrypted "Fixed" or "Point to Point", line-of site system. There must be a transmitting antenna and a receiving antenna for every service. Note: Wireless Internet service differs from your "wireless" phone in that it will only function with a clear line-of-site connection.
