Abstract

Techniques and systems for selectively performing band-switching operations are provided. For example, a method, computing device, or computer-program product may be provided, and may include receiving a communication from a first device, wherein the communication is received on a channel of a first WiFi frequency band, wherein the communication is received using a first WiFi circuit of the computing device, and wherein the computing device is a node of a mesh network. The method, computing device, or computer-program product may further include determining whether the first device is a node of the mesh network, determining a second device to which to transmit the communication, and determining whether the second device is a node of the mesh network. The method, computing device, or computer-program product may further include determining whether to transmit the communication to the second device on a second WiFi frequency band, wherein the second WiFi frequency band is different from the first WiFi frequency band, and wherein determining whether to transmit the communication on the second WiFi frequency band depends on whether the first device is a node of the mesh network.
