摘要： A wireless device in an ad hoc network detects other wireless devices within radio range and establishes synchronization with the detected wireless devices. The wireless device operates in a power save mode and wakes up, or turns on, periodically or on demand to implement discoverability. A received probe request packet or beacon packet contains information which allows the receiving wireless device to discover the transmitting wireless device. The wireless device may operate in a discoverable mode or in an active discovery mode.

摘要： A first wireless devices establishes an association with a second wireless device by sending a connection request packet to a previously-discovered second wireless device. The second wireless device identifies the received packet as a connection request and responds with a connection response packet, thereby establishing an association between the first and second wireless devices. The wireless devices can then, for example, send and receive data.

摘要： A portable media player device is capable of operating in a wireless network. The wireless portable media player device can bootstrap and synchronize with an ad hoc network with low power consumption. Neighbor portable media player devices in an ad hoc network can be discovered by the wireless portable media player device. The portable media player device can establish and terminate connections to neighbor portable media player devices. The portable media player device can transfer data in a high speed data transfer mode or a power save data transfer mode, while concurrently permitting discovery by other devices. The portable media player device operates in a power save mode during an inactive portion of a periodic discovery interval.

摘要： Discovery of services between devices is provided prior to establishing a connection between devices, including wireless-enabled devices or devices that are communicatively coupled to wireless access points. Discovering services prior to establishing a connection may facilitate finding a desired service. The services that may be discovered may be, for example, print services, camera services, PDA services or any other suitable services. Services may be discovered using 802.11, UWB or any other suitable wireless technology. As one example, particular services may be requested. As another example, services that are provided by a device may be advertised.

摘要： A wireless mesh network enables multiple devices near each other to transmit simultaneously, thus allowing increased network bandwidth. Prior to transmitting, a device may determine various parameters of the wireless medium on which it desires to transmit. For example, the device may determine whether the intended recipient device is close enough, and verify that any other transmitting and receiving devices are far enough away. If these or any other suitable criteria are met, the device can transmit simultaneously with other devices in the vicinity.

摘要： A wireless station is connected to a wireless network through an access point and can establish a direct client-to-client connection to a second wireless station. The wireless station can communicate directly with the second wireless station without involving the access point. The wireless station communicates with the wired network and with other wireless stations through the access point. The second wireless station may have an infrastructure connection to the access point or may be independent.
