WIRELESS SIGNAL TRANSCEIVER WITH AUTOMATIC MODE CHANGE, AND METHOD
First Claim
1. A wireless signal transceiver, comprising:
- wireless signal transmission means for transmitting and receiving signals in one or more wireless networks;
a microprocessor and memory;
wherein the memory comprises a scan mode program, the execution of which by the microprocessor causes the wireless signal transceiver toreceive and store in the memory one or more predefined wireless network identifiers; and
enable one scan mode at a time from a set of scan modes, wherein the set of scan modes comprises;
an active scan mode of a wireless network, in which the wireless signal transceiver repeatedly transmits a probe request message on one or more channels, until the wireless signal transceiver receives a probe response message from the wireless network, which case results in a successful active scan, or until a fulfillment of a predetermined set of criteria terminates the active scan, which case results in a failed active scan;
a passive scan mode of the wireless network, in which the wireless signal transceiver does not send anything to or via the wireless network but waits for a received wireless network identifier from at least one of the one or more wireless networks;
wherein the scan mode program, when executed by the microprocessor, causes the wireless signal transceiver to enable the active scan mode in response to a successful active scan or to a reception of a wireless network identifier that matches at least one of the predefined wireless network identifiers stored in the memory of the wireless signal transceiver; and
wherein the scan mode program, when executed by the microprocessor, causes the wireless signal transceiver to enable the passive scan mode in response to a failed active scan.

Abstract
A wireless signal transceiver receiving and storing predefined wireless network identifiers and a scan mode program for enabling either an active or passive scan mode. In the active scan mode, the transceiver repeatedly transmits probe request messages until the transceiver receives a probe response message from the network (successful active scan) or until a predetermined criterion terminates the active scan (failed active scan). In the passive scan mode, the transceiver does not send anything but waits for a received network identifier from one or more wireless networks. The transceiver enables the active scan mode in response to a successful active scan or to a reception of a wireless network identifier that matches at least one of the predefined identifiers stored in memory. The transceiver enables the passive scan mode in response to a failed active scan.
