c96657948d5044969d3c53893fe9eef7 | 103 329 | 4.1 Overview | The idea of a central coordination point (CCP) is to coordinate between multiple devices and/or multiple wireless networks using single wireless communication solution or multiple wireless communication solutions. The aim is to further improve the use of spectrum. The main idea is that a central device should coordinat... |
c96657948d5044969d3c53893fe9eef7 | 103 329 | 4.2.1 General | A CCP concept for sharing with other incumbent services and applications is intended to take away the burden of implementing the needed mitigation techniques for the used spectrum in each device. Another benefit of this concept is that the CCP can sense the incumbent services at the edges of the installed area with a b... |
c96657948d5044969d3c53893fe9eef7 | 103 329 | 4.2.2 Incumbent Protection | CCP controlled WIA systems employ a centralized coordination with an centralized or an distributed spectrum sensing to identify free and occupied frequency ranges in the 5,8 GHz WIA band. The spectrum sensing unit (SSU) may have multiple radio interfaces or an universal radio interface for monitoring a number of channe... |
c96657948d5044969d3c53893fe9eef7 | 103 329 | 4.3.1 General | The intra-system coexistence, as achieved by the CCP concept, fulfils the viewpoint of an automatic adaptive coexistence management mechanism. The CCP shall organize the spectrum access for multiple WIA systems within the 5,8 GHz WIA band. Currently many coexistence issues and mitigation techniques exist, because there... |
c96657948d5044969d3c53893fe9eef7 | 103 329 | 4.3.2 Inter-Network Sensing Assistance | WIA system 1 (see Figure 3) or WIA device(s) belonging to WIA system 1 can be requested to sense the operating channel of WIA system 2 and report the results to a CCP. This could be useful for networks consisting of low-powered devices with limited sensing capability. The CCP collects location information and operating... |
