A method includes selecting upstream and downstream aggregated MAC service data unit (AMSDU) sizes for communications between a client device, an access point, and an controller in a network system. The upstream and downstream AMSDU sizes may be separately selected based on the maximum transmission unit (MTU) size for communications in a secure tunnel between the controller and the access point to avoid fragmentation and reassembly of AMSDUs transmitted in a single MTU. The upstream and downstream AMSDU sizes may be selected to be less or equal to the MTU size.

Method and apparatus to control TX/RX AMSDU size based on the negotiated maximum transmission unit in the tunnel between a controller and an access point

A host controller having a first communication interface, or protocol, writes to and reads from one or more slave devices each having a second communication interface, or protocol, which is different from the first, through a translation device, or integrated circuit, that is responsive to command streams from the host controller. The present invention provides a high-level communications protocol by which command information and data are passed to a translation device, and the translation device interprets these commands and engages in the desired data transfer operation between the host controller and the slave devices. In a further aspect of the present invention, the high-level communications protocol also includes commands interpreted by the translation device to achieve data transfers between the host controller and the translation device, including accessing internal registers and I/O ports of the translation device.

Exemplary embodiments of methods and apparatuses to provide shielding from key cracking in wireless networks are described. In one embodiment, a first frame having a first content is identified. Determination is made whether the first frame needs to be shielded. A second frame having at least a portion of the first content is transmitted in response to determining that the first frame needs to be shielded. The first frame has data encrypted with a first encryption and the second frame has data encrypted with a second encryption.

Shielding in wireless networks

A multi-user bus is divided into a number of bus portions, one for each user. Each bus portion is coupled, at one end, to one of the multiple users and through an impedance matching network to the other bus portions in a star configuration. The disclosed embodiment teaches various resistive impedance matching networks.
