Abstract

The invention provides a LoRa power detection method and device and a transmitting circuit, and relates to the technical field of communication. The LoRa power detection method and device are appliedto the transmitting circuit, the transmitting circuit comprises a LoRa module, a power detection circuit and a radio frequency front end, the power detection circuit is arranged at the position closeto the radio frequency front end, and the method comprises the steps of: obtaining the actual value of the current transmitting power through the power detection circuit; detecting the actual value ofthe current transmitting power to obtain a power error value; and based on the power error value, performing emission compensation through the LoRa module. The condition of inaccurate transmitting power caused by transmitting power open-loop control is relieved; and the network reliability of the LoRa system is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a LoRa power detection method, device and transmission circuit. Background technique [0002] The current LoRa radio frequency transmission power control is an open-loop mode, and a fixed level of transmission power is performed through software configuration, and there is no detection of the actual transmission power of the air interface. Due to uncertain factors such as the network environment, radio frequency channel, and antenna, the actual transmit power of the air interface will deviate greatly from the set power level. For example, the TX Power is set to 20dBm, but due to the attenuation of the transmission path and the influence of antenna gain, the actual transmitted power is 2-8dB lower. Contents of the invention [0003] The purpose of the present invention is to provide a LoRa power detection method, device and transmission circuit to alleviate the i...
