Wi-Fi 7 service launching in October
Uninterrupted speeds of 100 Mbps or more guaranteed
Ulsan residents will be able to stream high-definition video and handle mobile work on city buses without interruption starting in October — even during crowded rush hours.
The city of Ulsan plans to replace public Wi-Fi equipment on all 762 of its city buses with Wi-Fi 7, the latest next-generation wireless standard, in line with the government's policy to guarantee basic communications rights for citizens and ease household telecommunications costs.
Wi-Fi 7 delivers significantly faster data transmission and response times than previous wireless standards and offers a data transmission bandwidth of 320 MHz — double that of its predecessor. The technology also employs Multi-Link Operation (MLO), which draws on multiple frequency bands simultaneously.
The upgrade will reduce connection drops and data bottlenecks even when buses are packed during rush hour or in motion, allowing for smoother high-definition video streaming and mobile work.
The monthly data allowance per bus will also increase from 200 gigabytes to 300 gigabytes. Even after the basic data cap is exhausted, quality-of-service standards will maintain a minimum speed of 100 Mbps, ensuring stable connectivity even when many users are connected at the same time.
The Ministry of Science and ICT designates areas where more than 10 percent of connections fail to reach 100 Mbps as "quality improvement recommendation zones" through its annual telecommunications service quality assessments, as part of broader efforts to raise service standards nationwide.
Equipment replacement will begin this month, carried out in stages during overnight and weekend hours when buses are not in service, with the new Wi-Fi service set to launch officially in October.
A city official said residents would be able to enjoy a better-quality digital wireless environment under the government's project to provide and support public Wi-Fi service on buses.
