Understanding of RF Cloud Interference Measurement and Modeling. 了解射频云干扰测量和建模。
IF 2.5 Q2 Engineering Pub Date : 2022-01-01 Epub Date: 2021-12-18 DOI: 10.1007/s10776-021-00541-8

Importance of spectrum regulation and management was first revealed on May of 1985 after the release of unlicensed ISM bands resulting in emergence of Wi-Fi, Bluetooth and many other wireless technologies that has affected our daily lives by enabling the emergence of the smart world and IoT era. Today, the idea of a liberated spectrum is circulating around, which can potentially direct wireless networking industry into another revolution by enabling a new paradigm in intelligent spectrum regulation and management. The RF signal radiated from IoT devices as well as other wireless technologies create an RF cloud causing co- and cross-interference to each other. Lack of a science and technology for understanding, measurement, and modeling of the RF cloud interference in near real-time results in inefficient utilization of the precious spectrum, a unique natural resource shared among all wireless devices of the universe in frequency, time, and space. Near real time forecasting of the RF cloud interference is essential to pursue the path to the optimal utilization of spectrum and a liberated spectrum management. This paper presents a historical perspective on the evolution of spectrum regulation and management, explains the diversified meanings of interference for different sectors of the wireless industry, and presents a path for implementing a theoretical foundation for interference monitoring and forecasting to enable the emergence of a liberated spectrum industry and a new paradigm in spectrum management and regulations.

1985年5月,未经许可的ISM频段发布,导致Wi-Fi,蓝牙和许多其他无线技术的出现,从而影响了我们的日常生活,使智能世界和物联网时代的出现,从而首次揭示了频谱监管和管理的重要性。如今,解放频谱的想法正在流传,这有可能通过实现智能频谱监管和管理的新范式,将无线网络行业带入另一场革命。从物联网设备以及其他无线技术发射的射频信号会产生射频云,从而相互产生共干扰和交叉干扰。缺乏对射频云干扰的近实时理解、测量和建模的科学和技术,导致宝贵频谱的利用效率低下,频谱是宇宙中所有无线设备在频率、时间和空间上共享的独特自然资源。射频云干扰的近实时预测对于实现频谱的最佳利用和频谱的自由管理至关重要。本文从历史的角度分析了频谱监管的演进,阐述了无线行业不同部门干扰的不同含义,提出了实现干扰监测和预测的理论基础的路径,使频谱行业得到解放,频谱管理和监管的新范式得以出现。

Proximity Detection During Epidemics: Direct UWB TOA Versus Machine Learning Based RSSI. 流行病期间的接近检测:直接超宽带TOA与基于机器学习的RSSI。
IF 2.5 Q2 Engineering Pub Date : 2022-01-01 Epub Date: 2022-10-14 DOI: 10.1007/s10776-022-00577-4

In this paper, we compare the direct TOA-based UWB technology with the RSSI-based BLE technology using machine learning algorithms for proximity detection during epidemics in terms of complexity of implementation, availability in existing smart phones, and precision of the results. We establish the theoretical limits on the precision and confidence of proximity estimation for both technologies using the Cramer Rao Lower Bound (CRLB) and validate the theoretical foundations using empirical data gathered in diverse practical operating scenarios. We perform our empirical experiments at eight distances in three flat environments and one non-flat environment encompassing both Line of Sight (LOS) and Obstructed-LOS (OLOS) situations. We also analyze the effects of various postures (eight angles) of the person carrying the sensor, and four on-body locations of the sensor. To estimate the range with BLE RSSI, we use 14 features for training the Gradient Boosted Machines (GBM) learning algorithm and we compare the precision of results with those obtained from memoryless UWB TOA ranging algorithm. We show that the memoryless UWB TOA algorithm achieves 93.60% confidence, slightly outperforming the 92.85% confidence of the BLE RSSI with more complex GBM machine learning (ML) algorithm and the need for substantial training. The training process for the RSSI-based BLE social distance measurements involved 3000 measurements to create a training dataset for each scenario and post-processing of data to extract 14 features of RSSI, and the ML classification algorithm consumed 200 s of computational time. The memoryless UWB ranging algorithm achieves more robust results without any need for training in less than 0.5 s of computation time.

Graphical abstract:

在本文中,我们比较了直接基于tob的UWB技术和基于rsi的BLE技术,使用机器学习算法在流行病期间进行接近检测,包括实现的复杂性、现有智能手机的可用性和结果的精度。我们使用Cramer Rao下界(CRLB)建立了两种技术的接近估计精度和置信度的理论限制,并使用在不同实际操作场景中收集的经验数据验证了理论基础。我们在三种平坦环境和一种非平坦环境中进行了八种距离的实证实验,包括视线(LOS)和视线受阻(OLOS)情况。我们还分析了携带传感器的人的不同姿势(八个角度)和传感器在身体上的四个位置的影响。为了使用BLE RSSI估计距离,我们使用了14个特征来训练梯度提升机(GBM)学习算法,并将结果的精度与无记忆UWB TOA测距算法的结果进行了比较。我们发现无记忆UWB TOA算法达到了93.60%的置信度,在更复杂的GBM机器学习(ML)算法和需要大量训练的情况下,略优于BLE RSSI的92.85%置信度。基于RSSI的BLE社交距离测量的训练过程涉及3000个测量值为每个场景创建训练数据集,并对数据进行后处理以提取14个RSSI特征,ML分类算法消耗200 s的计算时间。无记忆超宽带测距算法在不需要训练的情况下,在不到0.5 s的计算时间内获得了更强的鲁棒性结果。图形化的简介:
