## Abstract

A method and system for activating and deactivating a communication module for an apparatus is disclosed herein. The method includes monitoring a power activity state for the apparatus, monitoring a power activity state for a router for the apparatus, and maintaining an activation state for the communication module as long as the power activity state of the apparatus or the router is active.

## Claims

### Claim 1

A method for activating and deactivating a modem for an antenna assembly for a vehicle, the method comprising:
receiving an activation signal at a processor from an ignition input of the vehicle or a universal serial bus (USB) port voltage of a vehicle device when the modem of the antenna assembly is in a low power sleep mode;
activating the modem from the low power sleep mode;
receiving an input deactivation signal at the processor from the ignition input of the vehicle and a router USB port voltage of the USB port voltage and deactivating the modem into the low power sleep mode.

### Claim 2 (depends on 1)

The method according to claim 1 wherein the antenna assembly comprises
a base comprising an interior surface, a sidewall and a plurality of heat dissipation elements outward from the sidewall,
the modem disposed within the base,
an antenna board disposed within the base and comprising a plurality of antenna elements; and a housing for covering the base.

### Claim 3 (depends on 2)

The method according to claim 2 wherein the plurality of antenna elements comprises at least one LTE antenna element, at least one WiFi antenna element, and at least one Global Positioning System/Global Navigation Satellite System (GPS/GNSS) antenna element.
