Abstract: A system and method for allowing mobile devices to simultaneously access a Subscriber Identity Module (SIM) are disclosed. The SIM contains a wireless transceiver, and the SIM may be located within a mobile phone, or it may be a stand-alone device. The mobile devices use a wireless protocol, such as Bluetooth, to retrieve identification information from the SIM. The devices then use this identification information to connect to a wireless communications network, such as a wireless local area network. Through this network the devices will be able to access the Internet. The SIM will never need to be removed and inserted from one device to another, and multiple devices can use the SIM simultaneously. Thus, the mobile phone will work regardless of whether other devices are also using the SIM.

Abstract: Systems and methods are described for secure and seamless roaming between internal and external networks. Double and triple tunnels may be used to connect a mobile node to a correspondent host. A mobile node may include the ability to connect to two networks simultaneously to enable seamless roaming between networks.

Abstract: Methods for coordinating power usage and link adaptation in wireless communications are described. Terminals and/or access points (APs) may attempt to modify terminals' transmit power in relation to a desired communication data transfer rate. Link adoption may also be used in conjunction with the described methods.

Abstract: A system and method for equalizing traffic between antenna beams is described. Aspects of the system and method may vary the beam widths to attempt to equalize traffic based on non-real-time communications and/or non-real-time communications.

Abstract: A system and method for assigning channel access is described. At least one of a terminal or an access point transmits a message to other entities where the message assigns access to an assignee and includes a duration field of a specified length. The unassigned terminals or access point remain silent for a duration specified in the duration field while the assignee has access to the channel.

Abstract: The present invention provides a network communication device and method for simultaneous connection establishment and traffic delivery in a network. The network communication device comprises a first interface for exchanging information with a network device, a second interface connected to the first interface for establishing a connection with the network device, and middleware logic for coordinating information exchange between the first interface and the second interface. The second interface comprises a clock and a clock value that may be dynamically altered. The network communication device may be a Bluetooth device or a Bluetooth Access Point and is capable of functioning in a scan state and a connect state simultaneously.
