Suppressing interference in a frequency hopping signal. The method includes receiving a frequency hopping signal for a signal of interest. The frequency hopping signal includes the signal of interest modulated using frequency hopping and wideband and narrowband interference. Prior to de-hopping the frequency hopping signal, one or more wideband interferences in the frequency hopping signal are identified. The one or more wideband interferences are suppressed to create a wideband interference suppressed signal. Subsequent to suppressing the one or more wideband interferences, the wideband interference suppressed signal is de-hopped to create a de-hopped signal. In the de-hopped signal, one or more narrowband interferences are identified. The one or more narrowband interferences are suppressed to create an interference suppressed signal. The interference suppressed signal is demodulated to create a demodulated signal.

A frequency hopping communication system uses measured intensity values, such as RSSI (received signal strength indication) values, of RF signals previously received on a particular channel to generate a signal threshold that is tailored for the particular channel and is to be applied to subsequent frequency hopping processes. The signal threshold is used for determining whether a received RF signal is from an actual transmission or is merely background noise.

Methods and apparatus are provided. In an example aspect, a method in a first wireless communication device of transmitting data is provided. The method includes determining that each of a plurality of frequency ranges is free for a transmission by the first wireless communication device, selecting one or more of the frequency ranges, and transmitting the data using one or more frequency ranges other than the selected one or more frequency ranges.

Methods and apparatus are provided. In an example aspect, a method of transmitting a signal is provided. The method includes transmitting a frequency hopping signal on a first plurality of frequency channels in a first bandwidth using a first interference detect and avoid (DAA) scheme for each of the plurality of frequency channels, detecting interference in a predetermined proportion of the first plurality of frequency channels, and transmitting the frequency hopping signal on a second plurality of frequency channels in a second bandwidth smaller than the first bandwidth without using the first interference DAA scheme in response to detecting interference in the predetermined proportion of the first plurality of frequency channels.

Wireless data communication method, for communication between a computer peripheral device and a receiver device including transmitting a datastream from a computer peripheral device to a receiver device, with a wireless communication protocol which may operate with a first frequency band and a second frequency band. Each of the bands may be divided into a plurality of sub-bands, which may be further divided into frequency channels. During a first time slot, the operation frequency channel may be a first operation frequency channel selected according to a first frequency hopping sequence from the frequency channels of one sub-band of the first frequency band. During a second time slot, the operation frequency channel may be selected according to a second frequency hopping sequence from the frequency channels of one sub-band of the plurality of sub-bands of the second frequency band. Adjacent frequency channels of any of the frequency hopping sequences may be of different sub-bands. A device implementing the method is also envisaged.
