摘要： A frequency-hopped spread-spectrum multiple-access (FHSS-MA) wideband transceiver may support frequency-division multiple-access (FDMA) functionality by including a plurality of digital chains corresponding to FHSS-MA physical channels, individually and dynamically compensated for in-phase/quadrature imbalance in the transmit and/or receive portion. A FHSS-MA transceiver supporting FDMA functionality may coordinate FH sequence selection among FHSS physical channels to minimize inter-channel interference while also supporting legacy FHSS-enabled devices (e.g., Bluetooth®). The FHSS-MA transceiver may be incorporated into a wireless bridge device to facilitate low-latency communications over wireless local-area networks (WLANs), wireless wide-area networks (WWANs) or broadcast, with multiple FHSS-enabled devices that may be paired with the wireless bridge device using FHSS-MA channels. The wireless bridge device may enable a FHSS-enabled device to re-pair with a personal device. Such wireless bridge devices may be networked into a wireless bridge network that may increase the number of FHSS-enabled devices that may be accommodated and/or increase coverage range.

摘要： A wireless wideband transceiver may be able to communicate with multiple frequency-hopped spread-spectrum (FHSS) devices concurrently over multiple frequencies over a short range by including a plurality of digital chains corresponding to the FHSS physical channels, individually and dynamically compensated for in-phase/quadrature imbalance in the transmit and/or receive portion. To further improve communications the transceiver may also mitigate cross interference between adjacent channel signals that are received and/or transmitted simultaneously, avoid false reception and/or transmission of co-channel signals, delay respective FHSS channels transmissions relative to other channels transmissions, speed up connection to FHSS devices and coordinate Time Division Duplexing (TDD) operation according to application dependent TX/RX binary pattern. A device that includes such a transceiver (FHSS-hotspot) may enable the concurrent usage of multiple commercially available FHSS peripheral devices without the need for additional personal host devices to be carried along with them, and in addition enable the concurrent usage of multiple commercially available FHSS personal data devices while reducing their radiation and/or latency and/or usage cost and/or power, to establish a localized multi-device multimedia session, and/or to interface with a communications network to communicate with remote parties, and/or to interface with broadcast devices to stream contents.
