Abstract
An example cooling system for a wireless networking device is presented. The cooling system includes a Peltier cooler disposed in thermal contact with a radio-frequency (RF) filter coupled to a transceiver disposed in the wireless networking device. Further, the cooling system includes a thermal management controller coupled to the Peltier cooler and the transceiver. The thermal management controller is configured to receive a signal indicating whether the transceiver is performing a data communication. In response to determining that the transceiver is performing the data communication, the thermal management controller operates the Peltier cooler to actively cool the RF filter. However, in response to determining that the transceiver is not performing the data communication while the wireless networking device is powered on, the thermal management controller operates the Peltier cooler to stop actively cooling the RF filter.
