System and methods for avoiding interference between communications in different frequency bands

A method of operating an electronic device that has wireless communications circuitry that communicates in at least first and second radio-frequency communications bands, wherein the second radio-frequency communications band is divided into channels and wherein the first radio-frequency communications band comprises a cellular telephone frequency band, the method comprising:

• with storage and processing circuitry in the electronic device, identifying whether frequency harmonics associated with communications in the first radio-frequency communications band interfere with communications in at least one channel of the second radio-frequency communications band, wherein identifying whether the frequency harmonics associated with the communications in the first communications band interfere with the communications in the at least one channel of the second radio-frequency communications band comprises identifying whether frequency harmonics associated with communications in the cellular telephone frequency band interfere with communications in the at least one channel of the second radio-frequency communications band;
• in response to identifying that the frequency harmonics associated with communications in the first radio-frequency communications band interfere with the at least one channel of the second radio-frequency communications band, providing control signals with the storage and processing circuitry to the wireless communications circuitry that prevent the wireless communications circuitry from communicating in the at least one channel of the second radio-frequency communications band by adjusting the communications in the second radio-frequency communications band;
• and
• with the wireless communications circuitry, receiving instructions from a base station that direct the wireless communications circuitry to communicate in a frequency range within the cellular telephone frequency band, wherein identifying whether the frequency harmonics associated with communications in the cellular telephone frequency band interfere with communications in the at least one channel of the second radio-frequency communications band comprises:
• identifying whether frequency harmonics associated with communications in the frequency range interfere with communications in the at least one channel of the second radio-frequency communications band.

A method of operating an electronic device, comprising:

• with wireless communications circuitry, receiving instructions from a base station that direct the electronic device to communicate with the base station in a first frequency channel;
• with processing circuitry having first and second transceivers, retrieving information from a database that identifies whether frequency harmonics associated with communications in the first frequency channel by the first transceiver interfere with communications in a second frequency channel by the second transceiver;
• and
• with processing circuitry, configuring the wireless communications circuitry to avoid communicating in the second frequency channel by adjusting the second transceiver to avoid the frequency harmonics of the first frequency channel.
