Reliable Security
Communications may be intercepted or monitored at a public Wi-Fi SPOT that are not encrypted. d Wi-Fi uses the WPA2 system to encrypt wireless sections connected to access point devices for secure communication.
How d Wi-Fi Security Works
The d Wi-Fi offers wireless security between an access point and a wireless LAN device.
When transmitting important information such as personal information through the Internet, we recommend to use additional security such as TLS or Internet VPN*1 to ensure security from wireless LAN devices to destination servers.
TLS and Internet VPNs ensure security even in wireless LAN areas, and therefore they are able to protect your connection even if the wireless LAN encryption is decoded.
- When you log in to d Wi-Fi, TLS is used for communication between your device and a DOCOMO's server. This encrypts your d ACCOUNT and d Wi-Fi password information to prevent data from being intercepted or tampered with.
- d Wi-Fi SPOTs support IEEE802.1X technology which supports automatic authentication with robust security.
You can configure it on your device.
- You may not use some VPN technologies as d Wi-Fi allocates a private address to your device.
Simultaneous Connections are Possible from Multiple Devices
You can use various Wi-Fi compatible devices such as PCs, tablets, and gaming devices in addition to smartphones.
Up to five devices can be connected simultaneously.
- The number of devices is identified with MAC address.
Two SSIDs (Connection Points)
SSID refers to the name assigned to each Wi-Fi connection access point. d Wi-Fi offers two SSIDs: 0001docomo and 0000docomo.
