摘要： A first wireless unit engages in contemporaneous participation in a plurality of wireless networks. A connection is established with a second wireless unit in a first wireless network. Then, a hold time-out period is determined, and the first wireless unit enters a hold mode with respect to the first wireless network. While in hold mode, the first wireless unit establishes a connection with a third wireless unit in a second wireless network. This may include the first wireless unit paging the third wireless unit and acting as a master unit in the second wireless network. Alternatively, the first wireless unit may periodically listen for paging messages from a master unit, and respond when paged, thereby becoming a slave in the second wireless network. The first wireless unit then participates in activities in the second wireless network. Upon expiration of the hold time-out period, the first wireless unit resumes active participation in the first wireless network. This may include determining a second hold time-out period to be used in connection with the second wireless network, and entering a hold mode with respect to the second wireless network.

摘要： The invention relates to synchronizing in communication systems by using a sequential correlation technique. A digital sequence known to the receiver, a so-called signature, is allocated a plurality of segments. The segments are correlated, segment for segment, in a correlator (300) which is equally as long as the segment. The segments may have the same or different bit patterns. When a first segment is received in the correlator (300) and the correlation value of this segment exceeds an associated threshold value, the segment is accepted as received and is saved in a memory (308) in response to a signal from the control unit (311). A timer (319) is set to a time point that corresponds to the length of the segments. There is then correlated a second segment whose correlation value on the signal from the timer (319) is added (304) to the value stored in the memory (308). If the sum exceeds an associated threshold value, the sum is stored in the memory (308). Detection continues in this way. When the sum of the correlation values of all segments have exceeded the threshold value of the last segment, there is generated a sync. time pulse signal (Ts). Should a threshold value not be exceeded, it is assumed that a wrong signature has been received, and detection of the first segment is recommenced.

摘要： An electronic communication device includes a high-rate RF wireless transmitter circuit (e.g., a TransferJet transmitter circuit) and a low-rate magnetically coupled receiver circuit (e.g., a Near Field Communication receiver circuit). The high-rate RF wireless transmitter circuit transmits a block of data to another proximately located communication device via RF signals using a first RF communication protocol. The low-rate magnetically coupled receiver circuit receives a communication control signal from the other proximately located communication device via magnetic coupling thereto using a second protocol that is different from the first RF communication protocol, and responds to the communication control signal by selectively triggering the high-rate RF wireless transmitter circuit to transmit another block of data when available for transmission.

摘要： An apparatus in a wideband radio transceiver for mitigating interference between a wideband radio operating in a wide frequency band and a narrowband radio operating in a narrow frequency band within the wide frequency band. The effects of transmissions by the wideband radio on the narrowband radio are reduced by creating by the wideband radio, a transmitter notch of decreased transmit power centered at a frequency in the wide frequency band that is fixed in relation to the wideband carrier frequency. The wideband carrier frequency is then adjusted so that the transmitter notch is aligned with the second radio's narrow frequency band. The effects of transmissions by the narrowband radio on the wideband radio are reduced by creating by the wideband radio, a fixed receiver notch of decreased receiver gain in the wideband receiver, and aligning the narrowband signal with the fixed receiver notch.
