§ 15.202   Certified operating frequency range.

   Client devices that operate in a master/client network may be certified
   if they have the capability of operating outside permissible part 15
   frequency bands, provided they operate on only permissible part 15
   frequencies under the control of the master device with which they
   communicate. Master devices marketed within the United States must be
   limited to operation on permissible part 15 frequencies. Client devices
   that can also act as master devices must meet the requirements of a
   master device. For the purposes of this section, a master device is
   defined as a device operating in a mode in which it has the capability
   to transmit without receiving an enabling signal. In this mode it is
   able to select a channel and initiate a network by sending enabling
   signals to other devices. A network always has at least one device
   operating in master mode. A client device is defined as a device
   operating in a mode in which the transmissions of the device are under
   control of the master. A device in client mode is not able to initiate
   a network.
