Certain implementations of the disclosed technology may include systems, methods, and computer-readable media for wireless geo-fencing. According to an example implementation, a method is provided that may include receiving a set of network identification addresses for a plurality of wireless access points (AP) associated with at least one geo-fence, generating filter coefficients based on the received set of network identification addresses, receiving a network identification address for an in-range wireless access point, generating a test representation of the received network identification address, and determining whether the test representation corresponds a potential member of the received set of network identification addresses associated with the at least one geo-fence. If the test representation corresponds a potential member of the received set of network identification addresses, the method may determine if the received network identification address for the in-range wireless access point is an actual member of the geo-fence.
