Abstract

A system and method for providing variable security levels in a wireless communication network. The present invention optimizes the often conflicting demands of highly secure wireless communications and high speed wireless communications. According to a preferred embodiment of the present invention, various security sensors are scanned to determine the likely presence of an intruder within a predetermined trust zone. If an intruder is likely present, the security level is changed to the highest setting, and consequently a lower data rate, while the intruder is identified. If the identified intruder is in fact a trusted node, the security level is returned to a lower setting. If the identified intruder is not a trusted node, the security level is maintained at an elevated state while the intruder is within the trust zone.

Claims13

Dependent claims

A method for providing variable level security comprising:

detecting the presence of an intruder wireless device within a trust zone, the trust zone, at a first security level, including at least one trusted device;
and
on the condition that the intruder wireless device was detected, establishing a second security level that is more secure than the first security level, wherein a security level at the at least one trusted device is increased from the first security level to the second security level.

Dependencies are inferred from the claim text.
