Systems and techniques for adaptive automatic acknowledgment handling are described. A described system includes a memory structure to store a data rate (DR) adaptation mode indicator, a frame check sequence (FCS) adaptation mode indicator, a preset DR parameter, and a preset FCS parameter; an extractor to extract a DR parameter from a received frame to produce an extracted DR parameter and extract a FCS parameter from the received frame to produce an extracted FCS parameter; a selector to select between the preset DR parameter and the extracted DR parameter based on the DR adaptation mode indicator to produce a selected DR parameter and select between the preset FCS parameter and the extracted FCS parameter based on the FCS adaptation mode indicator to produce a selected FCS parameter; and a generator to generate an acknowledgment to the received frame based on the selected DR parameter and the selected FCS parameter.

Adaptive acknowledgment transmissions

An example method of assessing one more communication channels includes receiving an indication to initiate channel assessment, receiving a user-selected first set of assessment parameters, and determining whether or not the first communication channel is busy based on the first set of assessment parameters. The method also includes replacing the first set of assessment parameters with a user-selected second set of assessment parameters, and determining whether or not the second communication channel is busy based on the second set of assessment parameters.

Configurable clear channel assessment

A circuit and a method for operating a node in a radio network, whereby nodes of the same radio network have a common network ID and each node individually is assigned a node ID, wherein during the reception of a current packet by a receiving circuit of the node, an address contained in the packet is determined, wherein reception of the current packet is continued when the determined address agrees with the network ID of the node and the node ID of the node, and wherein during reception of the current packet, the reception of the current packet is terminated and the receiving circuit is controlled based on a case decision, when the determined address does not agree with the network ID of the node or the node ID of the node.

Circuit and method for operating a node in a radio network

In one embodiment, a transceiver may set a first receive frequency of a first channel of the transceiver and a second receive frequency of a second channel of the transceiver. The transceiver may receive, during a first time interval, a first radio frequency (RF) signal on the first channel. The transceiver may determine that a first measured value indicative of a first detectable received RF signal on the first channel exceeds a first predetermined threshold, and in response, receive a first data frame on the first channel. The transceiver may receive, during a second time interval, a second RF signal on the second channel. The transceiver determine that a second measured value indicative of a second detectable received RF signal on the second channel exceeds the first predetermined threshold, and in response, receive a second data frame on the second channel.
