Security
Security is a key concern when it comes to a wireless Internet connection. Vista Broadband's Network employs more encryption and levels of security than even a T1. Vista does not use 802.11/Wi-Fi equipment (which has well known security issues). Every customer has an individually provisioned point-to-point circuit that is only capable of communications between the client and Vista's network. No broadcast technology is used (i.e., Wi-Fi) that would allow unauthorized snooping or eavesdropping. To further enhance security, Vista employs directional antennas throughout its network to ensure that wireless signals are only received at the locations where they are intended to eliminate interception. Finally, the wireless traffic itself is encrypted over the air via proprietary encryption schemes employed directly in the radios, and adaptively changed during transmissions. Because of these advanced security features, Vista's wireless segment is actually more secure than a standard T1, which has no encryption. It is still important to recognize that Internet access over any technology (T1, DSL, Cable, and fixed wireless) creates an open doorway to your network. A firewall is recommended to prevent unauthorized access into your network from the Internet.
