Abstract: A grilling apparatus (1) with a housing (2), a grilling-product-receiving device (4) held on the housing (2), a heating region (5) arranged below the grilling-product-receiving device (4), an extraction device (6) and at least one filter unit (14, 15, 16, 18) which is connected in terms of flow to the extraction device (6), wherein, during the grilling operation, the extraction device (6) sucks up the fumes arising during the grilling via at least one extraction duct (9) and feeds said fumes to the at least one filter unit (14, 15, 16, 18), wherein a housing cover (7) which is arranged above the grilling-product-receiving device (4) and at least partially covers the latter is provided, and in that the at least one extraction duct (9) is arranged in the housing cover (7).

Abstract: The present invention enhances the dynamic frequency selection 9DFS) algorithms used in Wireless LANs by adding a channel swapping mechanism. The aim of the traditional DFS algorithm is to dynamically select channels in a wireless LAN in such a way that the best performance is achieved. However, not always the optimal channel selection is achieved. This invention describes an addition to the DFS algorithm in such a way that two APs can decide to swap channels instead of one AP switching to another channel. To avoid the problem of sub-optimal channel selection, a requesting AP sends Swap Requests to other APs in order to sense the willingness of other APs to swap channels with the requesting AP.

Abstract: A wireless communication network contains a plurality of spatially distributed communication devices (access point devices and station devices) for exchanging wireless signal frames. A device processes signal frames only when a strength of the signals exceeds a carrier detection threshold. Devices defer an intended transmission upon detection of a wireless signal with a strength greater than a defer threshold prior to the intended transmission. A measuring circuit performs a first measurement of a first signal strength of signals from access point devices and a second measurement of a second signal strength of signals from station devices associated with a first one of the access point devices. A threshold adjustment circuit first sets the carrier detection threshold of a first one of the access point devices above the first signal strength. The second measurement is performed when said first setting has taken effect.

Abstract: The present invention describes an algorithm for the assignment of channels used by access points (APs) in wireless LANs in a dynamic way in order to achieve the best performance. The assignment of channels is based on a procedure in which an AP is passively listening on the other channels during idle time. The AP is calculating the optimal channel with the least interference and sharing. If the AP experiences too much disturbance, it will decide to switch to the calculated optimal channel.

Abstract: A wireless communication network contains a plurality of spatially distributed access point devices and station devices. Each station device communicating in the network exclusively via an associated one of the access point devices. The station devices select the associated one of the access point devices dynamically.
