Abstract: A system is disclosed that may include an access point and a first wireless basic service set providing data transfer and a second wireless basic service set providing data transfer. The first and second wireless basic service sets are serviced by the access point concurrently and independent from the respective other wireless basic service set, wherein the access point may include a first MAC entity to process first data and a second MAC entity to process second data and wherein the first basic service set is configured to support a mix of contemporary wireless standards and legacy wireless standards and the second basic service set is configured to support only contemporary wireless standards and to operate at a greater data throughput than the first basic service set.

Abstract: A communication system may be configured to provide multiple levels of security for a communication link between a first node and a second node of a network. The system may be further configured to select a first level of security from the multiple levels of security for transmitting first data send by a first client via the first node to the second node and to select a second level of security from the multiple levels of security for transmitting second data send by a second client via the first node to the second node, the second level of security being different than the first level of security.

Abstract: A communication system may be configured to control by a security controller the use of a node in a network for a service or application to transmit data via the node, wherein the security controller controls the use of the node based on a predetermined list indicating whether the service or application is allowed for the node, the predetermined list including combined identifiers for client applications and identifiers for network nodes.

Abstract: A base station for wireless communication comprises a receiver and a processor. The receiver has a first operating state and a second operating state with different power consumption levels. In the first operating state, the receiver is configured to receive a signal. The processor is coupled to the receiver to switch the receiver between the first and second operating states.

Abstract: One embodiment of the present invention relates to a method for key management in a communications network. In this method, a public key authentication scheme is carried out between a security controller and a plurality of nodes to establish a plurality of node-to-security-controller (NSC) keys. The NSC keys are respectively associated with the plurality of nodes and are used for secure communication between the security controller and the respective nodes. Other methods and devices are also disclosed.

Abstract: Embodiments related to Wireless Local Area Networks and access points for a Wireless Local Area Network are described and depicted.

Abstract: In a method for classifying data packet units, each comprising a group of data packet parameters which comprises a plurality of data packet parameters, a subgroup of data packet parameters for configuring a classification key is selected, the data packet units are divided into data packet classes on the basis of the classification key and a selected classification algorithm, and the data packet units are allocated to further data packet parameters which correspond to the respective data packet class.

Abstract: System and method for providing secure communications is provided. Initially, an exchange protocol, such as a password-authenticated key exchange protocol, is used to create a shared secret. From the shared secret, two keys are created: a utilized key and a stored key. The utilized key is used to encrypt messages between nodes. When it is time to replace the utilized key to maintain security, the stored key is utilized to encrypt messages for generating/distributing a new shared secret. The new shared secret is then used to generate a new utilized key and a new stored key. This process may be repeated any number of times to maintain security.

Abstract: A method of providing contention access to a communication medium in a communications network includes transmitting priority information with each of a plurality of network nodes prior to a shared-contention transmission opportunity. The priority information for each node indicates a priority level of a frame that the node intends to transmit on the communication medium during the shared-contention transmission opportunity. At least one of the nodes is assigned to a contention window of a plurality of contention windows within the transmission opportunity based on the transmitted priority information.
