US Classification:

380270, 380277

Abstract:

One aspect involves a communication that contains a portion encrypted with a selected key can be wirelessly transmitted by a part for reception and decryption by plural tags. A different aspect involves a tag receiving a first sequence of wireless communications that each contain sequencing information regarding the first sequence, while receiving a second sequence of wireless communications that each include sequencing information regarding the second sequence, and further involves monitoring the sequencing information from received communications of the first sequence while separately monitoring the sequencing information from received communications of the second sequence.

Abstract:

A tag has a circuit portion that functions as a reader capable of wireless communication with other tags. According to a different aspect, a tag has a circuit portion with first and second modes, the circuitry consuming less power in the second mode than the first mode, and exiting the second mode only in response to an act by a human. According to yet another aspect, a tag can receive wireless communications conforming to one of a cellular telephone network communication protocol, a satellite communication protocol, and a wireless computer network communication protocol. The tag responds to receipt of a predetermined wireless signal conforming to the one protocol by carrying out one of first action that includes causing the tag to enter an electronically secure state, or a second action that includes causing the tag to exit the electronically secure state.

Abstract:

In a distributed antenna system (DAS) and a local area network (LAN), a common communication infrastructure distributes data from radio-based and Internet-based sources. A radio equipment (RE) of the DAS interfaces to a LAN segment. For the downlink, a gateway maps radio signal data from a radio equipment controller (REC) and data packets from a switch to mixed-data frames using a radio data interface protocol for transmission in the DAS. At the RE, the signal data and data packets are retrieved from the mixed-data frames and provided to the air interface and LAN segment, respectively. For the uplink from the RE, the radio signal data from the air interface and the data packets from the LAN segment are mapped to mixed-data frames and transmitted to the gateway. The gateway retrieves the signal samples and data packets from the mixed-data frames for transfer to the REC and switch, respectively.
