WIRELESS COMMUNICATIONS ADAPTER FOR A NETWORK DEVICE

摘要

Described herein is an adapter that can facilitate communications between a bi-polar serial communications port of a network device and a mobile device that communicates wirelessly. The adapter can include circuitry configured to communicate and receive wireless signals to and from the mobile device over air at least at 1 Mbit/s. Such circuitry can also be configured to consume at most 0.5 W and convert a wireless signal into a unipolar signal, and vice versa. The adapter can also include an energy storage component configured to store energy from a bi-polar serial signal received from the port. The adapter can also include circuitry, configured to receive the stored electrical energy and convert a unipolar signal to a bi-polar serial signal compatible with the port using the received energy. The adapter can also include circuitry configured to convert a bipolar signal to a unipolar signal.

1. A communications adapter, comprising:
low-power wireless communications circuitry, configured to:
communicate and receive wireless communications signals to and from a mobile device over air at least at 1 megabit per second;consume at most 0.5 watts of power; andconvert a wireless communications signal into a unipolar communications signal, and vice versa; electrical energy storage circuitry, including an electrical energy storage component configured to store at least some electrical energy from a bi-polar serial communications signal received from a bi-polar serial communications port of a network device; bi-polar conversion circuitry, configured to:
receive electrical energy stored by the electrical energy storage component; andconvert a unipolar communications signal, communicated by the low-power wireless communications circuitry, to a bi-polar serial communications signal compatible with the bi-polar serial communications port of the network device using the electrical energy received from the electrical energy storage component; and unipolar conversion circuitry configured to convert a bipolar communications signal, communicated from the bi-polar serial communications port of the network device, to a unipolar communications signal.
