As the radio spectrum becomes increasingly crowded, the superior spectral capacity in the visible light range becomes increasingly attractive. Visible light communication (VLC) technology uses the light waves from light emitting diode (LED) lamps and overheads to stream data and connect people as a more efficient, more available, and more secure alternative to Wireless Fidelity (Wi-Fi). The aim of this paper is to enable a host-to-host Transmission Control Protocol/Internet Protocol (TCP/IP) connection over serial ports using VLC. The data is transmitted from a serial port to a virtual tunneling device (TUN) so that the processor receives the information without using the Ethernet connection. In order to check the status of network connections between two computers, the ping tool is used. Pinging checks whether it is possible to reach one computer from another. Moreover, frequency dependence of the communication is tested. The setup reached 96% success rate and 239.233 ms average ping time in 41 trials for a 15 cm separation distance between the two transmitter and receiver pairs. Success rate of communication broke down at 70 cm separation distance under a dark room environment. A realistic application scenario of our presented technique would be to connect a computer that has its TUN programmed to provide an Ethernet connection over an optimized LiFi design setup with state-of-the-art characteristics in terms of data rate and power efficiency.

随着无线电频谱变得越来越拥挤，可见光范围内的出色频谱容量变得越来越有吸引力。可见光通信（VLC）技术使用来自发光二极管（LED）灯的光波和高架开销来传输数据并连接人们，这是无线保真（Wi-Fi）的一种更高效，更可用和更安全的替代方法。本文的目的是使用VLC通过串行端口实现主机到主机的传输控制协议/ Internet协议（TCP / IP）连接。数据从串行端口传输到虚拟隧道设备（TUN），以便处理器无需使用以太网连接即可接收信息。为了检查两台计算机之间的网络连接状态，使用了ping工具。ping检查是否可以从另一台计算机到达一台计算机。而且，测试了通信的频率依赖性。在两个发射器和接收器对之间的15厘米分离距离下，该设置在41次试验中达到96％的成功率和239.233 ms的平均ping时间。在黑暗的房间环境中，沟通的成功率在70厘米的分隔距离处破裂。我们提出的技术的实际应用场景是连接一台经过编程的TUN的计算机，以通过优化的LiFi设计设置提供以太网连接，该设置具有数据速率和功率效率方面的最新特性。在41个试验中，两个发射器对和接收器对之间15厘米的分隔距离平均233毫秒ping时间。在黑暗的房间环境中，沟通的成功率在70厘米的分隔距离处破裂。我们提出的技术的实际应用场景是连接一台经过编程的TUN的计算机，以通过优化的LiFi设计设置提供以太网连接，该设置具有数据速率和功率效率方面的最新特性。在41个试验中，两个发射器和接收器对之间的15 cm分隔距离的平均ping时间为233 ms。在黑暗的房间环境中，沟通的成功率在70厘米的分隔距离处破裂。我们提出的技术的实际应用场景是连接一台经过编程的TUN的计算机，以通过优化的LiFi设计设置提供以太网连接，该设置具有数据速率和功率效率方面的最新特性。
