Filed:

Jul 10, 2000

Appl. No.:

09/612802

Inventors:

Albert T. Chow - Hillsdale NJ

Assignee:

ATT Corp. - New York NY

International Classification:

H04M 166

US Classification:

455411, 455410, 455443

Abstract:

Automatic activation (i. e. , first time access) of digital wireless/cellular mobile telephones with a private/localized wireless/cellular system (i. e. a secondary system) occurs within an area having an overlapping macrocellular primary wireless communication system (i. e. , a dominant system). Operation of the secondary access procedure is achieved by shielding/masking an access and authentication process for the secondary system from interference from the control signal levels of the dominant wireless communication system. During the first time access, the secondary system is supplied with the SID and MIN and ESN numbers for authentication and resultant access.

US Classification:

455411, 455410, 455443

Abstract:

Automatic activation of a wireless device with a first wireless communication system occurs within an area having an overlapping second wireless communication system. Operation of the first communication system access procedure is achieved by masking an access and authentication process for the second communication system from interference from the control signal levels of the second wireless communication system. During the first time access, the first communication system is supplied with the SID and MIN and ESN numbers for authentication and access.

Appl. No.:

11/725776

Inventors:

Thomas Killian - Westfield NJ, US
Christopher Rice - Parsippany NJ, US

Assignee:

AT&T Intellectual Property II, L.P. - Reno NV

International Classification:

G08B 13/14

US Classification:

3405724, 3405721

Abstract:

A method and system for tracking variable conditions using radio frequency identification (RFID) are disclosed. In embodiments of the present invention, an RFID sensor tag is used to measure a condition. The condition can be any measurable condition such as location, temperature, humidity, pressure, time, date, inertial measurements, etc. Variable data representing the measured condition is read from the RFID sensor tag in order to track the measured condition. The variable data can be read from RFID sensor tags in addition to reading tag identification data from RFID tags, so that the variable data can be associated with tag identification data.

International Classification:

H04M 1/66

US Classification:

455411, 455410, 455443, 455515

Abstract:

A secondary Ethernet-like wireless communication system overlapped by a dominant Ethernet-like wireless communication system, and including radio access and communication for activation, association, and authentication of a wireless device in the secondary Ethernet-like wireless communication system. An automated private service activation (APSA) port is used for accepting access and communication requests of a wireless device seeking activation, association and authentication in the secondary Ethernet-like wireless communication system. The APSA port provides an access and communication channel for radiating signals at a level exceeding a signal level of the access and communication channel only within limited spatial constraints. In addition the APSA port provides space for receiving the wireless device for activation and communication in the secondary Ethernet-like wireless communication system.
