摘要:

使用无线保真(WiFi)的室内无线通信正在成为发达国家和发展中国家物联网(IoT)和云机器人成功的主要需求。由于不同的工作条件、干扰、障碍物和使用的建筑材料类型,很难预测室内环境中的路径损耗分量,这对网络设计至关重要。据观察,为西方国家提出的室内路径损耗模型不能直接用于印度的情况下,由于在建筑材料利用,平面图等的变化,在本文中,我们提出了一种非确定性的统计室内路径损耗模型-塔塔室内路径损耗模型(T-IPLM),可用于2.4 - 2.5 GHz,工业科学和医疗(ISM)频段。为了提出和验证,我们在不同的条件下进行了几次路测,如繁忙的办公场所有障碍物,开放的办公场所,走廊,食堂和多层办公室位置等。我们还将T-IPLM与流行的路径损耗模型进行了比较,如ITU-R和对数距离;与其他模型相比,T-IPLM与路测结果非常吻合。我们相信,T-IPLM模型可广泛用于设计常规WiFi通信所需的精确室内通信网络,以及物联网和云机器人的部署和运营。

英文摘要:

Indoor wireless communication using Wireless Fidelity (WiFi) is becoming a major need for the success of Internet of Things (IoT) and cloud robotics in both developed and developing countries. With different operating conditions, interference, obstacles and type of building materials used, it is difficult to predict the path loss components in an indoor environment, which are crucial for the network design. It has been observed that the indoor path loss models proposed for western countries cannot be directly used in Indian scenarios due to variations in building materials utilized, floor plans, etc. In this paper, we have proposed a non-deterministic statistical indoor path loss model- Tata Indoor Path Loss Model (T-IPLM) which can be used for the 2.4 - 2.5 GHz, Industrial Scientific and Medical (ISM) band. To propose and validate, we have conducted several drive tests with different conditions such as busy office premise with obstacles, open office premise, corridor, canteen, and multi-storey office locations, etc. We have also compared T-IPLM with popular path loss models such as ITU-R and Log-distance; T-IPLM matches closely with the drive test results as compared to other models. We believe that T-IPLM model can be used extensively to design accurate indoor communication networks required for regular WiFi communications and deployment and operations of IoT and cloud robotics.
