根据报告的内容,本文主要概括了非地面网络(NTN)的发展现状、标准化情况、生态系统、全球展望、应用场景、频谱使用以及NTN终端等内容。 关键点如下: 1. **NTN发展现状**:NTN包括卫星网络、高空平台和无人机系统,可提供地面网络无法覆盖区域的连接。3GPP从Release 17开始定义了支持NTN的5G标准,包括NR-NTN和IoT-NTN。 2. **标准化情况**:3GPP是NTN标准化工作的主要组织,ITU负责频谱协调,ETSI、GSMA等组织也在推动NTN标准化。 3. **生态系统**:NTN生态系统包括终端用户、移动网络运营商、卫星网络运营商、设备制造商等,各方需合作实现NTN服务。 4. **全球展望**:NTN可提供宽带接入、物联网、车联网等应用,预计将推动NTN与地面网络融合,实现无缝覆盖。 5. **应用场景**:NTN可应用于消费者宽带接入、企业宽带接入、海事通信、车联网、工业物联网等领域。 6. **频谱使用**:NTN使用MSS、FSS等频段,需协调NTN与地面网络在频谱上的共存。 7. **NTN终端**:需开发支持NTN的芯片、操作系统和终端,以实现NTN服务。
**NTN如何改变移动连接?** **NTN在哪些行业有应用?** **NTN面临哪些技术挑战?**
