Network communications for device with co-located radio transmitters and receivers

A device, comprising:

• a wireless local area network (WLAN) radio controller;
• a first antenna connected to the WLAN radio controller by a first transmission line;
• a ZIGBEE radio controller connected to an amplifier;
• a second antenna connected to the ZIGBEE radio controller by a second transmission line and configured to receive a first radio frequency signal, wherein the ZIGBEE radio controller is configured to execute instructions for:
• setting a receive gain of the amplifier to a first gain value,
• detecting that the WLAN radio controller is transmitting a second radio frequency signal using the first antenna, and
• setting, based on the detecting, the receive gain of the amplifier to a second gain value, wherein the second gain value is less than the first gain value, and wherein the amplifier is configured to change a magnitude of the received first radio frequency signal based on the second gain value;
• and
• a processor that is configured to execute instructions for:
• determining that the WLAN radio controller is allocated a WLAN channel to transmit radio frequency signals using the first antenna,
• setting a transmit power of the WLAN radio controller to a first transmit power value,
• determining that the device is executing a functionality including voice communication or multimedia streaming causing the WLAN radio controller to transmit the second radio frequency signal,
• determining a packet loss threshold for an active connection of the ZIGBEE radio controller, wherein the packet loss threshold indicates a limit on dropped ZIGBEE packets for the active connection,
• determining that a duty cycle of the WLAN radio controller is greater than the packet loss threshold,
• setting the transmit power of the WLAN radio controller to a second transmit power value, wherein the second transmit power value is less than the first transmit power value,
• determining that a packet transfer rate associated with the WLAN radio controller is less than a minimum packet transfer rate for the functionality, and
• setting the transmit power of the WLAN radio controller to a third transmit power value, wherein the third transmit power value is greater than the second transmit power value.
