Method and system for broadband near-field communication (BNC) utilizing full spectrum capture (FSC) supporting concurrent charging and communication
First Claim
1. A near field communications (NFC) tag comprising:
- a modulator operable to generate a digital radio frequency (RF) signal;
a digital-to-analog converter (DAC) operable to convert the digital RF signal to an analog RF signal for wireless transmission to a first device, wherein the analog RF signal is at a power level below a spurious emissions mask;
a digital demodulator operable to digitally downconvert a frequency spectrum of a wireless signal received from the first device; and
a control unit operable to provide harvested energy, from the wireless signal received from the first device, to a second device that is paired with the NFC tag.

Abstract
A charging device includes an integrated broadband transceiver that is operable to communicate wireless signals at a power level that is below a spurious emissions mask. The wireless signals are communicated over a designated frequency spectrum band via one or more antennas. The wireless signals convey data between the charging device and a communication device via one or more usable channels within the frequency spectrum band utilized by the integrated broadband transceiver. Concurrent with the communicating, charging of the communication device occurs. One or more usable channels within the frequency spectrum band utilized by the integrated broadband transceiver may be detected. The charging and the communication of the wireless signals occurs currently on the same ones or different ones of the one or more antennas. The detected one or more usable channels may be aggregated and utilized for the communication by the integrated broadband transceiver.
