1. A space-efficient cellular modem device for machine-to-machine communications, the modem device comprising:
a multi-layer printed circuit board defining a top side and a bottom side and including a first circuit layer adjacent the top side, a second circuit layer adjacent the bottom side, a ground plane layer, and a power plane layer, the ground and power plane layers located between the first and second circuit layers; a cellular transceiver module configured to communicate over a cellular wireless cellular network, the cellular transceiver module comprising a processor and attached to a top side of the multi-layer printed circuit board; electrical power-management components attached to the multi-layer printed circuit board, the power-management components in electrical communication with the cellular transceiver module; a first plurality of electrically-conductive pins in electrical connection with the cellular transceiver module and aligned along a first pin axis to form a first row of pins, each of the first plurality of pins extending outwardly and away from the bottom side of the multi-layer printed circuit board;
a second plurality of electrically-conductive pins in electrical connection with the cellular transceiver module and aligned along a second pin axis to form a second row of pins, each of the second plurality of pins extending outwardly and away from the bottom side of the multi-layer printed circuit board, the second row of pins located opposite the first row of pins; and a communications port in electrical communication with the cellular transceiver module, the communications port configured to receive and transmit communication signals over the cellular wireless network. |
