摘要： The invention relates to a method in a wireless communication system (1) comprising wireless terminals (MT1-MT4), a communication channel (CH) and at, least one access point (AP1, AP2) and access point controller (AC1, AC2). The method comprises the steps of activating at least one data transmission connection between the wireless terminal (MT1-MT4) and the access point (AP1), in which information is transmitted in packets, forming data frames (FR) for the transmission of the packets, supplementing said data frame (FR) with at least one item of error checking data, in whose formation at least a part of the information contained in the data frame (FR) is used, converting said data frames (FR) into signals to be transmitted on the communication channel, receiving signals transmitted on the communication channel and converting them into data frames, forming reference.data corresponding to at least one item of error checking data on the basis of the information received in the data frame (FR), comparing the received error checking data with said reference data, and setting up an acknowledgement message, in which information on the received parts of the data frame (FR) is transmitted from the device (MT1-MT4) receiving the data frames to the device (AP1, AP2).

摘要： Systems and methods for a communication system implementing a short range communication link between devices advertising available information and services, and user devices which may initiate a request for further information or services. The communication system provides a low power solution utilizing an optimized combination of a carrier sensing and frequency division multiple access to avoid collisions. The optimization involves the use of a random mean zero value offset appended to the advertising devices' transmission frames. The offset increases the likelihood that a first advertising device will recognize the transmissions of another advertiser's transmissions (i.e., determining that a channel is busy) and avoid unnecessary transmissions that will result in collisions. Upon recognition, the first advertiser may shift its transmission frame accordingly, thereby avoiding transmission collisions between advertisers. The communication system may be implemented in either a StandAlone LowRate system, or in a device with a pre-existing operational Bluetooth implementation.
