First Claim
1. A communication device, comprising:
- a dual-band antenna array configured to communicate radio frequency (RF) signals with a remote device in an RF band and to communicate millimeter wave (MMW) signals with the remote device in a MMW frequency band, wherein the MMW frequency band is above the RF band, wherein the dual-band antenna array is switchable in response to a control signal between an operation in the RF band and an operation in the MMW frequency band;
at least one transceiver configured to generate the RF signals conveying data, the data including a command to the remote device to transmit probe signals in the MMW frequency band, wherein the at least one transceiver is further configured to receive the probe signals via the dual-band antenna array in the MMW frequency band, wherein the at least one transceiver is initialized with first antenna beam steering parameters to facilitate a first antenna beam of the dual-band antenna array for the operation in the MMW frequency band; and
a controller configured to generate the first antenna beam steering parameters of the at least one transceiver based on the probe signals and further configured to generate the control signal to switch the dual-band antenna array to the operation in the MMW frequency band after transmission of the RF signals.

Abstract
In accordance with one or more embodiments, a communication device includes a dual-band antenna array configured to communicate RF signals in an RF band and to communicate MMW signals in a MMW frequency band with a remote device. At least one transceiver is configured to generate the RF signals conveying a command to the remote device to transmit probe signals in the MMW frequency band, to receive the probe signals via the dual-band antenna in the MMW frequency band, and is initialized with first antenna beam steering parameters to facilitate a first antenna beam of the dual-band antenna array for the operation in the MMW frequency band. A controller is configured to generate the first antenna beam steering parameters based on the probe signals and to generate the control signal to switch the dual-band antenna array to the operation in the MMW frequency band after transmission of the RF signals.
