The demand for mobile broadband services is increasing exponentially alongside with user expectations regarding the reachability of these services and their prices. This paper presents an integrated satellite and fifth generation (5G) network for providing inflight connectivity and evaluates the economic viability of offering broadband connectivity to passengers on commercial airplanes by the development of a techno-economic framework, which considers both capital and operational expenditures to compute the total cost of ownership (TCO) and an average cost per user and per Megabyte. Results show high operational costs mainly due to satellite bandwidth usage. Therefore, caching popular content on the network onboard is beneficial to reduce the traffic carried over the satellite link, thus lowering the operational costs as well. Furthermore, the framework is used to compare the identified business models for Inflight Entertainment and Connectivity offerings and their pricing strategies, alongside a benchmark against the current inflight connectivity pricing. Finally, a sensitivity analysis is elaborated in order to mitigate the uncertainty of inputs (e.g., rate of caching) used to feed the TCO model. Following concrete recommendations are the main result of this research: (1) Providing inflight broadband services with a 2–5 Mbps throughput per user is feasible if satellite communications is integrated into the 5G network. (2) Caching popular data reduces the operational costs and hence the average cost per user (from 25% to 32% depending on the caching rate adopted). (3) This framework allows to provide recommendations on the best suited business models and related pricing schemes.

使用集成卫星 5G 网络对机上连接进行技术经济分析

随着用户对这些服务的可达性及其价格的期望,对移动宽带服务的需求呈指数级增长。本文介绍了一种用于提供机上连接的集成卫星和第五代 (5G) 网络,并通过开发技术经济框架来评估为商用飞机上的乘客提供宽带连接的经济可行性,该框架考虑了资本和运营支出来计算总拥有成本 (TCO) 以及每位用户和每兆字节的平均成本。结果显示高运营成本主要是由于卫星带宽的使用。因此,在机载网络上缓存流行内容有利于减少通过卫星链路传输的流量,从而降低运营成本。此外,该框架用于比较已确定的机上娱乐和连接产品的商业模式及其定价策略,以及与当前机上连接定价的基准。最后,详细阐述了敏感性分析,以减轻用于输入 TCO 模型的输入(例如,缓存速率)的不确定性。以下具体建议是这项研究的主要结果: (1) 如果将卫星通信集成到 5G 网络中,则提供每个用户 2-5 Mbps 吞吐量的机上宽带服务是可行的。(2) 缓存流行数据降低了运营成本,从而降低了每个用户的平均成本(从 25% 到 32%,具体取决于采用的缓存率)。(3) 该框架允许就最适合的商业模式和相关定价方案提供建议。
