衰减环境自动检测用GNSS
On the use of GNSS for Automatic Detection of Attenuating Environments
摘要：
当不同的无线电应用共享相同的频谱时，通过衰减材料进行分离是减轻潜在干扰的一种方式。针对5150-5350 MHz中的WLAN设备的室内限制是旨在使WLAN设备在提供足够衰减以实现与其他服务共享的环境中操作的监管措施的示例。在本文中，我们调查是否衰减环境可以自动检测，而无需用户交互。我们不是检测室内位置，而是直接寻找衰减环境的检测。其基本思想是，全球导航卫星服务（GNSS）的信号几乎可以在地球上任何可以看到天空的地方接收到。在这些信号被衰减的情况下，假设接收设备处于衰减环境中。为了表征这样的环境，我们评估可检测的GNSS卫星和它们的载噪密度。示例测量表明，GNSS原始数据可有助于区分低衰减位置和高衰减位置。这些测量是用现成的Android平板电脑中的GNSS接收器进行的，以显示该方法的可行性。
英文摘要：
When different radio applications share the same spectrum, the separation by attenuating material is a way to mitigate potential interference. The indoor restriction for WLAN devices in 5150-5350 MHz is an example for a regulatory measure that aims at having WLAN devices operating in an environment that provides sufficient attenuation to enable sharing with other services. In this paper we investigate whether an attenuating environment can be automatically detected without user interaction. Instead of detecting an indoor location, we are directly looking for a detection of an attenuating environment. The basic idea is that signals from global navigation satellite services (GNSS) can be received practically everywhere on earth where there is a view to the sky. Where these signals are attenuated, the receiving device is assumed to be in an attenuating environment. In order to characterize such environment, we evaluate the detectable GNSS satellites and their carrier-to-noise density. Example measurements show that GNSS raw data can help to distinguish between low-attenuating locations and higher-attenuating locations. These measurements were conducted with GNSS receiver in an off-the-shelf Android tablet in order to show the feasibility of the approach.
