A communication device includes a modem and circuitry. The modem communicates with a cellular network that is linked to a data network to which one or more target servers are coupled. The circuitry is configured to hold a token that identifies the communication device for assignment to a selected service plan in a management server of the cellular network, to trigger, based on the token, an onboarding request to the management server for assigning the selected service plan to the communication device, and, after the selected service plan has been assigned to the communication device in the management server, to communicate with a target server, via the cellular network and over the data network, in accordance with the selected service plan.

A system and method for frequency reuse for wireless point-to-point backhaul. Frequency reuse is enabled through the cancellation of interfering signals generated by interference sources. In one embodiment, a conventional dish antenna is complemented with one or more additional auxiliary antennas (e.g., isotropic). The one or more additional auxiliary antennas enable cancellation of interfering signals whose direction of arrival (DOA) is off the dish antenna's bore-sight.

The system and method of the present disclosure exploit the fact that an undesired phase offset between signals up-converted and transmitted by transmitters of at least two transceivers is correlative with a phase offset between signals received and down-converted by receivers of the at least two transceivers. Such correlation occurs when the transmitter and receiver in each of the at least two transceivers share the same local oscillator and thus experience the same or very similar random phase noise. Using this fact, the system and method of the present disclosure are configured to measure the phase offset between signals received and down-converted by the receivers of the at least two transceivers and then use the measured phase offset to compensate for the phase offset between the signals up-converted by the transmitters of the at least two transceivers. This compensation allows MIMO communication, such as spatial multiplexing, to be better performed.
