Aspects of the subject disclosure may include, for example, a method for use with a communication device that includes: communicating in a first frequency band with a remote device via at least one transceiver, wherein the remote device is oriented at a direction relative to the communication device, wherein the communicating is in accordance with first antenna beam steering parameters and a first antenna beam corresponding to the direction; and, communicating in a second frequency band with the remote device via the at least one transceiver, wherein the second frequency band is higher than the first frequency band, wherein the at least one transceiver is pre-initialized with second antenna beam steering parameters to generate a second antenna beam corresponding to the direction, and wherein the second antenna beam steering parameters are generated based on the first antenna beam steering parameters.

Provided are a power carrier signal coupling circuit and a communication system. The power carrier signal coupling circuit includes a first power carrier signal coupling channel and a second power carrier signal coupling channel. A phase of a three-phase alternating current (AC) power line serves as a common channel, the first power carrier signal coupling channel is arranged between the common channel and one of two phases of the three-phase AC power line other than the phase of the three-phase AC power line serving as the common channel; and the second power carrier signal coupling channel is arranged between the common channel and the other of the two phases of the three-phase AC power line other than the phase of the three-phase AC power line serving as the common channel.
