Only a third of passengers on the UK's railways seem happy with the wifi service they receive on the train. People increasingly expect free and reliable internet wherever they go and are frustrated that train journeys interrupt the entertainment and communications they value for lifestyle and work.The problem is not for lack of attention. The Government knows how much this matters to people and has called for rail franchises to include free wifi from 2020\. Although the initiative itself will guarantee no more than 1 Mbps per head, it sends a clear signal to the train operators who have so far found it difficult to justify investment in the infrastructure needed over the timeframe of the franchise contracts. Network Rail Infrastructure Limited (NRIL) is the owner and operator of most of the rail infrastructure in Great Britain and is at the forefront of attempts to find innovative solutions for this market failure.HS2 is the next major railway infrastructure project in the UK and an excellent opportunity to prove high bandwidth, reliable internet services for entire journeys. VILIRI's approach is based on Optical Wireless Communications (OWC) that uses Infra-Red (IR) frequencies to send data between train and trackside at 10Gigabits per second (10Gbps). This is more than enough for all types of internet browsing, real time communications and effectively unlimited capacity for each passenger.The innovation is to use advanced optics with high levels of concentration and carefully matched sensors that can take low power IR signals and process them reliably in real time. This needs transceivers on the train and along the track so that data is transferred by line of sight from each transceiver in turn. The quality of service achievable will support operational communications and security CCTV picture transfers, for example, as well as information and internet for the passengers.The project will enhance the capability of the optical links by advanced signal processing and multiple channels where needed. Care will be taken to ensure that the optics remain clean and clear in all weathers. Most importantly, the business case for installing the system as part of the railway infrastructure will be covered by the revenue that additional internet services will bring while passengers enjoy the basic internet service without direct charges. Capital costs will be reduced by internet connection within the provision of optical fibre that has to be laid for signalling and other functions.

英国铁路上只有三分之一的乘客对他们在火车上获得的WiFi服务感到满意。人们越来越希望无论走到哪里都能享受免费可靠的互联网服务，而火车旅行打断了他们在生活和工作中所重视的娱乐和通信，这让他们感到沮丧。政府知道这对人们有多重要，并呼吁铁路特许经营权从2020年开始包括免费WiFi。虽然该倡议本身将保证每人不超过1 Mbps，但它向列车运营商发出了一个明确的信号，他们迄今为止发现很难证明在特许经营合同的时间范围内对所需基础设施的投资是合理的。Network Rail Infrastructure Limited（NRIL）是英国大部分铁路基础设施的所有者和运营商，并处于为这一市场失败寻找创新解决方案的最前沿。HS2是英国下一个主要铁路基础设施项目，也是证明整个旅程高带宽、可靠互联网服务的绝佳机会。VILIRI的方法是基于光无线通信（OWC），使用红外（IR）频率以每秒10千兆比特（10Gbps）的速度在列车和轨道之间发送数据。这是绰绰有余的所有类型的互联网浏览，真实的时间通信和有效的无限容量为每个乘客。创新是使用先进的光学与高水平的浓度和精心匹配的传感器，可以采取低功率红外信号和处理他们可靠的真实的时间。这就需要在列车上和沿着轨道上安装收发器，以便通过视线依次从每个收发器传输数据。可实现的服务质量将支持业务通信和安全闭路电视图像传输，例如，以及为乘客提供信息和互联网。该项目将通过先进的信号处理和所需的多通道来提高光学链路的能力。应注意确保光学器件在任何天气下都保持清洁和清晰。最重要的是，安装该系统作为铁路基础设施的一部分的商业案例将由额外互联网服务带来的收入所覆盖，而乘客可以享受基本的互联网服务而无需直接收费。在提供光纤的范围内连接互联网将降低资本成本，光纤必须用于信号和其他功能。
