摘要： A method is provided for interfacing telecommunication devices. A base unit is connected to a landline for wireless communication. The base unit has a power supply operating at a power supply frequency. A mobile unit is provided for wireless communication with the base unit. The base unit is interfaced to the mobile unit using an interface protocol that has a plurality of frames. Each frame is for transmitting signals from the mobile unit to the base unit and from the base unit to the mobile unit. The frames have a specified frame length. An interference frequency is detected at either the base unit or the mobile unit. The interference frequency is compared with the power supply frequency. The frames are synchronized with the power supply and the specified frame length is adjusted based on the power supply frequency when the interference frequency and the power supply frequency are substantially the same.

摘要： A method and system are provided for selecting a communication channel in a wireless communication system. The method and system include defining a plurality of channel groups. Each channel group corresponds to a plurality of communication channels. The method and system also includes setting a set counter to the channel group having the current communication channel. Further, the set counter is incremented after each channel hop and an index counter is incremented when the set counter resets. Next, a sequence number is determined as a function of the set counter and an identifier is associated with the wireless communication device. The method and system continues with determining an offset as a function of the sequence number and the index counter and determining a next communication channel as a function of the set counter and the offset.

摘要： A method and system are disclosed for shifting frequency subsets to avoid base station interference in a frequency hopping cordless telephone system. A base station communicates with the handsets using frequencies selected from active frequency subsets. Frequency subsets are shifted to avoid interference by selecting frequencies initially from a defined number of active frequency subsets where each of the active frequency subsets is used before repeating an active frequency subset. The number of active frequency subsets is then changed for a defined period of time to change the period with which the active frequency subsets are used. After the defined period of time, the number of active frequency subsets is returned to the defined number of active frequency subsets.
