Embodiment Construction

[0041] The present invention will be further described below in conjunction with accompanying drawing.

[0042] like figure 1 As shown, the power dual-mode communication architecture based on the IEEE1901.1 communication standard of the present invention is composed of a broadband carrier communication (HPLC) chip, a software radio frequency module (or chip), and a power line drive circuit. HPLC chip and power line drive circuit constitute the traditional wired broadband power carrier communication. HPLC baseband chip and software radio frequency module (or chip) constitute the wireless broadband communication.

[0043] The HPLC baseband chip is a chip based on the IEEE1901.1 standard. Since the IEEE1901.1 standard adopts the OFDM communication method, it requires a high frequency error (<0.5%) between transceivers. If the center frequency of the transceiver radio frequency carrier is 500MHz, then the crystal oscillator stability of the system is required to be better than ...
