A free, ultrafast public Wi-Fi system using the mobile hotspot network (MHN) technology will be installed within Seoul’s subways The MHN technology was developed by the Electronics and Telecommunications Research Institute (ETRI).

The consortium led by P&P Plus announced on Feb. 13 that it has signed a memorandum of understanding (MOU) with the Seoul Metropolitan Government and the Seoul Metro Corp. to improve Seoul’s metro system telecom service.

Under the agreement, the consortium will set up a free, superfast Wi-Fi system within Seoul’s subway lines 1 to 9 using the MHN technology. The technology was introduced by the ETRI at the Mobile World Congress in Barcelona, Spain, earlier last year. The consortium is also planning to advance the technology to MHN-E in 2019 to make its transmission speed 10 times faster.

When the government provides the 22 to 23.6 GHz bandwidth for a flexible access common spectrum, the consortium can utilize it as wireless backhaul and provide fast-moving vehicles, including subways and KTX, with Wi-Fi networks that are 20 to 100 times faster than the existing one.

Cho Yoon-sung, director of P&P Plus, said, “The technology allows up to 10 million users in a subway train or within 1 kilometer from a station to use the superfast Wi-Fi service for free a day. We will install the system as soon as possible.”
