释放LTE在下一代铁路通信中的潜力
Unleashing the Potential of LTE for Next Generation Railway Communications
AI总结：
本文探讨LTE作为GSM-R继任者，凭借技术优势支持铁路服务迁移与未来服务，提升运营效率与安全。
摘要：
在日益苛刻的市场环境中，铁路服务将承受巨大压力，宽带无线通信研究必须继续努力改进。基于成熟的窄带GSM技术，全球移动通信系统-铁路（GSM-R）已被部署用于运营和语音通信。尽管GSM-R满足了当前铁路服务的要求，但其容量有限且成本高昂，限制了运营效率、乘客安全和运输质量的提升。4G长期演进（LTE）预计将成为GSM-R的自然继任者，不仅因为其技术优势和不断提升的性能，还因为通用通信系统当前的演进趋势。本文考察了LTE的关键特性及其技术能力，以支持现有铁路服务的迁移和未来服务的提供。
英文摘要：
In an increasingly demanding marketplace that will put great strain on railway services, research on broadband wireless communication must continue to strive for improvement. Based on the mature narrowband GSM technology, Global System for Mobile Communications-Railways (GSM-R) has been deployed both for operational and voice communications. Although GSM-R fulfills the requirements of current railway services, it imposes limited capacity and high costs that restrict enhancements of operational efficiency, passenger security and transport quality. 4G Long Term Evolution (LTE) is expected to be the natural successor of GSM-R not only for its technical advantages and increasing performance, but also due to the current evolution of general-purpose communication systems. This paper examines the key features of LTE as well as its technical ability to support both the migration of current railway services and the provisioning of future ones.
