1. An apparatus, comprising:
- a radio frequency (RF) filter block to selectively transmit or receive signals in a wireless network using a selected one of a first frequency band or a second frequency band, the first frequency band being an Industrial, Scientific, Medical (ISM) or Universal National Information Infrastructure (UNII) band and the second frequency band being a millimeter wave (mmWave) band, wherein the RF filter block comprises;
a first RF filter to pass filter a control signal for transmission or receipt in the first frequency band;
a second RF filter to pass filter a data signal for transmission or receipt in the second frequency band; and
a switch to selectively couple the control signal to the first RF filter or the data signal to the second RF filter; and
a controller coupled to the RF filter block to control the RF filter block to select the first frequency band to transmit or receive the control signal to facilitate initial communication by the apparatus in the wireless network, said transmit or receive of the control signal to subsequently enable the controller to control the RF filter block to select the second frequency band to transmit or receive the data signal.

17. An apparatus, comprising:
-
circuitry including a radio frequency (RF) filter block to selectively transmit or receive signals in a wireless network using a selected one of a first frequency band or a second frequency band, the first frequency band being an Industrial, Scientific, Medical (ISM) or Universal National Information Infrastructure (UNII) band and the second frequency band being a millimeter wave (mmWave) band; one or more frequency synthesizers coupled to the circuitry to provide a first and a second carrier signal to the circuitry, the first carrier signal having a frequency lower than frequency of the second carrier signal, the first and the second carrier signal to modulate or demodulate signals to be transmitted or received through the first and second frequency bands, respectively; and a controller coupled to the RF filter block to control the RF filter block to select the first frequency band to transmit or receive a control signal to facilitate initial communication by the apparatus in the wireless network, said transmit or receive of the control signal to subsequently enable the controller to control the RF filter block to select the second frequency band to transmit or receive the data signal. - View Dependent Claims (18, 19, 20, 21, 22)
