The customer presence (CP) connects their network to an Ethernet to Ethernet router implementing Network Address Translation(NAT)which is similar to the Internet connection sharing software included with current Microsoft operating systems(OS). The router then connects to a radio that transmits the signal back to Dotnet's point-of-presence(POP) where the data is then transported over standard copper and fiber communications facilities and routed on the Internet as needed.

The connection deviates from current customer connections in two ways.
The connection from CP to Dotnet POP is typically implemented over public switched telephone network(PSTN) connections. The CP equipment (CPE) is typically one or more personal computers(PCs) running Microsoft OS's and using 56K modems.

Under either connection the data between CPE and POP are encapsulated in Internet Protocol(IP) and Point to Point Protocol(PPP). Any attempt to eavesdrop would require physical access to the connection, either phone line or antenna placed between CPE and POP, and the ability to de-encapsulate the data. De-encapsulation of the wireless link is further complicated by its relative infancy in the communications industry, encapsulation of IP, in PPP over Ethernet(PPPoE), in Ethernet, in TurboCell Superpacket aggregation. The TurboCell Superpacket aggregation is a closed standard owned by a single corporation. While not easy, such surveillance is possible and thus any sensitive information exchanged over the Internet should be encrypted using an end-to-end encryption method.

The wireless connection employs considerably better security at the CP. The Ethernet-to-Ethernet router provides a single point of security policy administration on a dedicated device. This connection avoids having user workstations or servers directly connect to the Internet. The default Configuration offers no services and thus blocks all in-bound connection attempts. With a dedicated hardware platform and administrative password control it becomes increasingly difficult for an intentional or accidental breach of security to occur. In the case of workstations directly connecting the possibility of end user intervention is also removed.

At Dotnet we believe that our Fixed Wireless Broadband Internet Access allows our customers to leverage next generation networking technology and the Internet to more effectively serve their customers in a secure fashion.
