KAI Prepares 5G WiFi Service on Long-Distance Trains, Here is the List

Managing Director of KAI, Bobby Rasyidin, targets the availability of 5G WiFi for use by passengers on long-distance trains starting from June 2026, coinciding with the holiday season. “There are now many complaints that the internet inside the trains is not good, streaming is not good. Therefore, we are striving to introduce a 5G network so that internet services are better starting from June-July,” said Bobby when met after the strategic tripartite memorandum of understanding (MoU) signing event held at Tanah Abang Station, Jakarta, on Wednesday (15/4/2026). Bobby stated that the presence of 5G WiFi is part of KAI’s efforts to improve entertainment services inside the trains. This step also serves as a response to complaints regarding the quality of internet on train routes. By improving the quality of internet services to be faster and better, said Bobby, passengers are expected to be able to stream videos or have better internet connectivity throughout the journey. The routes prioritised for the 5G WiFi service enhancement are Semarang, Yogyakarta, and Surabaya, which are busy with passengers during holiday periods. “We prioritise our main trains first, such as those to Yogyakarta. Perhaps KA Taksaka first, then those on the northern route like KA Argo, those are what we prioritise,” said Bobby. PT Kereta Api Indonesia (Persero) (KAI), PT Solusi Sinergi Digital Tbk (SURGE), and PT Huawei Tech Investment (Huawei) signed a memorandum of understanding to accelerate the adoption of 5G+AI technology across Indonesia’s entire railway system. In the MoU, the three parties will jointly explore three main areas, namely cooperation on ICT (information and communication technology) infrastructure, 5G FRMCS (future railway mobile communication system) networks and applications, and AI-based freight wagon detection. ICT infrastructure cooperation provides backbone networks, wireless coverage at stations and depots, as well as cloud solutions to ensure business continuity and service expansion flexibility. Furthermore, the cooperation will provide 5G FRMCS networks to improve railway safety, efficiency, and service quality, including a pilot project on the Rangkasbitung-Tanah Abang route for level crossing safety and intelligent train scheduling. AI-based freight wagon detection is the application of AI-based video analysis to enable intelligent disruption detection and automatic warnings on freight trains, thereby increasing turnaround efficiency and reducing manual inspections.
