一个概念验证系统已经开发出来，可以在5G/6G网络和地球探测卫星服务(EESS)之间实现实时地理空间频谱共享。一种简单的算法在存在来自5G/6G发射机的潜在干扰时暂停网络传输，在24 GHz NR2频段提供99.6%的网络可用性，同时保护在23.8 GHz频段运行的所有当前工作的EESS辐射计。一种更复杂的算法可以修改传输功率级别和(如有必要)网络流量(类似于公民宽带无线电服务使用的方法)，可以减少干扰，从而不会对网络可用性产生不利影响。除了防止干扰，RGSS还为无线和天气/气候社区提供了其他重大好处，包括改善网络性能和覆盖范围、支持网络架构、网元、终端和新的或更灵敏的辐射计的变化的能力，以及一种测试和监督带外辐射要求合规性的简单机制。RGSS还与现有的频谱管理系统兼容。
A proof of concept system that enables real-time geospatial spectrum sharing between 5G/6G networks and Earth Exploration Satellite Services (EESS) has been developed. A simple algorithm that pauses network transmissions when there is potential interference from 5G/6G transmitters provides 99.6% network availability in the 24 GHz NR2 band while protecting all currently working EESS radiometers operating in the 23.8 GHz band. A more sophisticated algorithm that modifies transmission power levels and (if necessary) network traffic (similar to the methodologies used by Citizens Broadband Radio Service) can reduce interference so that there is no adverse impact on network availability. In addition to preventing interference, RGSS provides other significant benefits to both the wireless and the weather/climate communities, including improving network performance and coverage, the ability to support changes in network architectures, network elements, endpoints, and new or more sensitive radiometers, and a simple mechanism to test and police compliance with out-of-band emission requirements. RGSS is also compatible with existing spectrum management systems.
