LoRa是一种通信方案，是使用ISM频段的低功率广域网（LPWAN）技术的一部分。它已经在研究和工业中看到了广泛的文档和使用，因为它的长覆盖范围高达20公里或更长，发射功率小于14 dB。此外，一些应用报告的理论电池寿命高达10年的现场部署的模块，利用该计划在无线传感器网络应用。此外，该方案对噪声损失以及通过其FEC的干扰突发非常有弹性。我们的目标是系统地回顾LoRa在农村景观，指标和相关验证方案中的用例的经验证据。此外，该研究还基于（i）该方案的数学函数（带宽使用，扩频因子，符号率，码片速率和标称比特率）（ii）用例（iii）测试床，评估指标和（iv）验证方法进行评估。对已发表的关于LoRa应用的主要研究进行了系统的文献综述。使用2010-2019年的文章。我们确定了21项相关的主要研究。这些报告对LoRa进行了一系列不同的评估。21例中有10例报告了新用例。作为一个可操作的结论，作者得出的结论是，在现场测试方面需要做更多的工作，因为尽管博茨瓦纳和南非都存在LoRa网络，但在这两个国家都没有找到关于性能/部署的文章。因此，该地区的研究人员可以研究该方案和MAC层的传播模型性能，能量效率以及该地区的信道接入挑战。
LoRa is a communication scheme that is part of the low power wide are network (LPWAN) technology using ISM bands. It has seen extensive documentation and use in research and industry due to its long coverage ranges of up-to 20Km or more with less than 14dB transmit power. Moreover, some applications report theoretical battery lives of upto 10years for field deployed modules utilising the scheme in WSN applications. Additionally, the scheme is very resilient to losses from noise, as well bursts of interference through its FEC. Our objective is to systematically review the empirical evidence of the use-cases of LoRa in rural landscapes, metrics and the relevant validation schemes. In addition the research is evaluated based on (i) mathematical function of the scheme (bandwidth use, spreading factor, symbol rate, chip rate and nominal bit rate) (ii) use-cases (iii) test-beds, metrics of evaluation and (iv) validation methods. A systematic literature review of published, refereed primary studies on LoRa applications was conducted. Using articles from 2010-2019. We identified 21 relevant primary studies. These reported a range of different assessments of LoRa. 10 out of 21 reported on novel use cases. As an actionable conclusion, the authors conclude that more work is needed in terms of field testing, as no articles could be found on performance/deployment in Botswana or South Africa despite the existence of LoRa networks in both countries. Thus researchers in the region can research propagation models performance, energy efficiency of the scheme and MAC layer as well as the channel access challenges for the region.
