摘　　要：为了满足在偏远地区、地下场景等供电条件困难的环境下,无线通信设备供电时长要求,文章提出了一种低功耗无线发射机发射功率计算方法,通过整个无线通信信道损耗和sub-GHz低功率收发天线芯片的数据表计算出无线发射机发射功率。通过仿真计算,相比传统发射机发射功率计算方法,该方法更精确地计算出发射端所需要的最低发射功率,提升了无线发射机能效,从而使得无线通信设备满足偏远地区、地下场景等供电条件困难环境下的供电时长要求。In order to meet the requirements of wireless communication equipment power supply time under the environment of difficult power supply conditions,such as remote areas,underground,this paper presents a transmission power calculation method for low-power wireless transmitter,the transmitting power of the wireless transmitter is calculated by the whole wireless communication channel loss and the data table of sub-GHz low power transceiver antenna chip.Through simulation calculation,compared with the traditional transmitter transmission power calculation method,the minimum transmission power required by the transmitter is more accurately calculated,and the energy efficiency of the transmitter is improved,so that the wireless communication equipment can meet the power supply time requirements under difficult power supply conditions such as remote areas and underground.
