Wireless apparatus having a transceiver equipped to support multiple wireless communication protocols
First Claim
1. An apparatus comprising:
- a wireless transceiver having a joint signal transmit/receive section, and a plurality of signal up/down conversion sections sharing said joint signal transmit/receive section, to selectively transmit and receive signals in accordance with a first and a second protocol, in a coordinated manner, to and from network devices of a first and a second wireless network; and
a controller coupled to the wireless transceiver to control said wireless transceiver to perform said transmits and receives in said coordinated manner, wherein the controller, in a coordinated manner, selectively couples a first signal up conversion section to the joint signal transmit/receive section to perform said transmit of signals to network device(s) of said first wireless network, while keeping a second signal up conversion section decoupled from the joint signal transmit/receive section preventing signals from being transmitted to network device(s) of said second wireless network.

Abstract
A wireless device is provided with a wireless transceiver having a joint signal transmit/receive section, and a number of signal up/down conversion sections to transmit and receive signals wirelessly in accordance with a first and a second protocol. The wireless device is further provided with a controller/signal processing section to control and perform, in a coordinated manner, the transmit and receive operations in accordance with the two protocols. In various embodiments, the wireless device is further provided with a processor programmed to implement a time sharing schedule to facilitate the coordinated control and performance of the transmit and receive operations. In some of these embodiments, the processor is further programmed to monitor the transmit and receive workloads of the two protocols and adaptively perform the coordinated control and signal processing, based at least in part on the observed workloads. In various embodiments, the protocols may be selected pairs of Bluetooth, 802.11, 802.11a, 802.11b, Home RF and the like. The wireless device may also be used as a master device or a gateway device of two wireless networks.

15. In an apparatus having a wireless transceiver including a joint signal transmit/receive section, and a plurality of signal up/down conversion sections sharing the joint signal transmit/receive section, a method of operation comprising:
-
(a) coupling a first signal up conversion section to the joint signal transmit/receive section to perform transmit of signals to network device(s) of a first wireless network in accordance with a first protocol, while keeping a second signal up conversion section de-coupled from the joint signal transmit/receive section to prevent signals from being transmitted to network device(s) of a second wireless network in accordance with a second protocol; and (b) coupling the second signal up conversion section to the joint signal transmit/receive section to perform transmit of signals to network device(s) of the second wireless network in accordance with the second protocol, while keeping the first signal up conversion section de-coupled from the joint signal transmit/receive section to prevent signals from being transmitted to network device(s) of the first wireless network in accordance with the first protocol. - View Dependent Claims (16, 17, 18, 19)
