Abstract: Dual band wireless local area network (WLAN) transceiver. A wireless communication device includes at least two different transceivers (or radios) therein to effectuate communications with other wireless communication devices using at least two respective frequency bands. Each of these two transceivers may have different respective circuitry (e.g., each may have a different respective power amplifier (PA) and/or other circuitry components). Coordination is made regarding when certain components of one transceiver turn on and operate when another transceiver may be transmitting or receiving communications. For example, the turn on of a PA and/or other circuitry components (e.g., such as components using or requiring high current) within one transceiver can be coordinated as to minimize deleterious effects regarding the operation of another transceiver. Moreover, latency existent within each of the respective transceiver chains within the wireless communication device (e.g., including baseband and radio portions) is accounted for regarding their respective concurrent operation.

Abstract: Various methods and systems are provided for space, frequency and time domain coexistence of RF signals. In one example, among others, a communication device includes a coexistence manager capable of monitoring operating conditions of a cellular modem and a coexistence assistant capable of monitoring operating conditions of a wireless connectivity unit. The coexistence manager is capable of modifying operation of the modem and/or unit based on an operating condition change. In another example, a method includes detecting a change in antenna isolation and/or operating temperature of a FE filter, determining filtering characteristics of the FE filter based at least in part upon the change, and modifying communications of coexisting communication protocols based at least in part upon the filtering characteristics. In another example, a TX/RX configuration for coexisting communication protocols is determined and communications in a protocol is modified based at least in part upon the TX/RX configuration.
