TV White Spaces技术是一种允许无线设备利用本地可用电视频道(TV White Spaces)的方法，可通过地理位置数据库实现。在给定主要服务覆盖区域边缘的假定干扰限制和保护裕度的情况下，地理位置数据库通知设备在给定位置可以使用哪些信道，并且在英国/欧盟的情况下，基于设备的技术特征可以在每个信道上使用哪些发射功率(EIRP)。英国监管机构英国通信办公室(Ofcom)启动了一项大规模的电视白空间技术和设备试点。信息和通信技术-雅典卫城卓越网络与信息和通信技术-焊料项目和其他项目合作，正在这一努力下进行一系列广泛的试验。这些试验的目的是测试空白空间技术的多个方面，包括空白空间设备和地理位置数据库的交互、数据库计算的信道可用性/功率的有效性以及对主要服务的相关干扰影响，以及空白空间设备的性能等。另一个关键目的是进行一些研究调查，例如电视空白空间资源与常规(许可/非许可)资源的聚合、次要共存问题和缓解此类问题的方法，以及具有挑战性的部署几何结构下的主要共存问题等。本文描述了我们的试验，它们的意图和特点，目标，以及一些早期观察。
TV White Spaces technology is a means of allowing wireless devices to opportunistically use locally-available TV channels (TV White Spaces), enabled by a geolocation database. The geolocation database informs the device of which channels can be used at a given location, and in the UK/EU case, which transmission powers (EIRPs) can be used on each channel based on the technical characteristics of the device, given an assumed interference limit and protection margin at the edge of the primary service coverage area(s). The UK regulator, Ofcom, has initiated a large-scale Pilot of TV White Spaces technology and devices. The ICT-ACROPOLIS Network of Excellence, teaming up with the ICT-SOLDER project and others, is running an extensive series of trials under this effort. The purpose of these trials is to test a number of aspects of white space technology, including the white space device and geolocation database interactions, the validity of the channel availability/powers calculations by the database and associated interference effects on primary services., and the performances of the white spaces devices, among others. An additional key purpose is to undertake a number of research investigations such as into aggregation of TV White Space resources with conventional (licensed/unlicensed) resources, secondary coexistence issues and means to mitigate such issues, and primary coexistence issues under challenging deployment geometries, among others. This paper describes our trials, their intentions and characteristics, objectives, and some early observations.
