Embodiment 1

[0045] The SOC communication chip combining NFC, power carrier and wireless of the present invention is a communication chip integrating NFC, PLC and WiFi. A single SoC chip includes NFC front end (AFE) / physical layer (PHY), PLC analog front end (AFE) , PLC physical layer (PHY), PLC data link layer (MAC); WiFi analog front end (AFE), WiFi physical layer (PHY), WiFi data link layer (MAC); also includes MCU microprocessor and its corresponding chip interface;

[0046] In order to save the area of ​​NFC, PLC and WiFi integrated chips, the modules of PLC and WiFi are shared to the greatest extent. Such as figure 1 As shown, the PLC input signal passes through the baseband low noise amplifier (101), and the signal after the WiFi input signal passes through the RF low noise amplifier and the mixer (102) is sent to the same receiving circuit, including the baseband signal amplifier (103), Low-pass filter (104), analog-to-digital converter (105), and digital filtering of the digital...

Abstract

The invention discloses a SOC communication chip combined with NFC, power carrier and wireless communication module, which combines short-distance NFC with home wireless range and long-distance power carrier communication mode for the first time, and extends the range of smart home controlled by mobile phones to the area of ​​residential areas or buildings. range, which is conducive to digging and opening some new applications. In the internal structure of the chip, NFC has a separate channel, which mainly communicates with devices such as mobile phones to receive and send control commands; the receiving and sending channels of PLC and WiFi can be used in combination to reduce communication delays and improve efficiency. This will greatly improve the efficiency of the entire system and meet the requirements of QoS, especially for voice and video applications. Moreover, when WiFi receiving and PLC transmitting are used in combination, the transmitting channel of WiFi and the receiving channel of PLC can be closed as needed to reduce the power consumption of the whole system.

Description

technical field [0001] The invention belongs to the field of microelectronic technology and network communication technology in electronic engineering, and relates to a SOC communication chip combining NFC, power carrier and wireless. Background technique [0002] NFC near-field communication is an extremely short-range communication technology that can communicate without contact at a distance of 4-5 cm. The main advantage is that it is convenient and safe, and it is not easy to leak secrets. At present, NFC has been used as a means of communication for mobile phones. It has many unique applications in scanning payment, unlocking mobile phones, and setting contactless passwords. [0003] PLC power carrier communication uses power lines for signal transmission, which is long and stable, and is currently widely used domestically and internationally. In addition, WiFi, as the most important communication method, has covered every household. However, WiFi communication has di...
