3 About our Wi-Fi network facilities

All School of Science buildings on the Hongo Campus are covered by a Wi-Fi network. The Wi-Fi network is a VLAN with IEEE 802.1X (EAP-TLS) authentication. The subnet for the relevant Department/laboratory can be accessed directly from anywhere on the network. Since the security type is WPA2 Enterprise, network access requires a user certificate. The ESSID for the School of Science Wi-Fi network is “sos” (School of Science); the network supports both the 2.4 GHz band (11 bgn) and the 5 GHz band (an).
