Wi-Fi (Wireless LAN)
Wi-Fi router uses 2.4 GHz frequency band WLAN between
2400 MHz and 2483.5 MHz.
Wireless Frequencies & Modulations information: On Wi-Fi
router package.
・2.4: 2400 MHz range
DS/OF: DSSS or OFDM modulation
4: Maximum interference range of 40 m
: Utilizes 2400 MHz–2483.5 MHz band, and
mobile identifier device bands are avoided.
・Available channels vary depending on the country.
・For use abroad aircraft, contact the airline beforehand.
・When using Wi-Fi in other countries, check local regulations
beforehand.
・Do not use Wi-Fi router near magnetic devices such as
electrical appliances or AV/OA devices.
- Magnetic/radio waves may hinder or disable
communication. Avoid microwave ovens.
- Use near a TV or radio, etc. may cause interference; may
affect TV reception.
- If there are multiple Wireless LAN access points using the
same channel, search may fail.
・Wireless LAN device operates same frequency band used
by industrial, scientific, consumer and medical equipment
including microwave ovens, premises radio stations for
identifying mobile units used in the manufacturing lines
of plants (radio stations requiring a license), specified low
power radio stations (radio stations requiring no license)
and amateur radio stations (radio stations requiring a
license).
1. Before using Wi-Fi router, confirm that premises radio
stations for identifying mobile units, specified low power
radio stations and amateur radio stations are not being
operated nearby.
2. If Wi-Fi router causes disruptive radio interference
with premises radio stations for identifying mobile units,
immediately change frequency band, stop use, or move to
another location to avoid crosstalk (e.g. wall partitions,
etc.).
・Since information is exchanged between terminals and the
Wireless LAN access points, an advantage of Wireless LAN
connections is that LAN connections can be freely enabled
within the reachable range of the signals. However, if
the security settings are not set, there is a possibility
that security issues may arise from the interception of
communication data and illegal intrusions. Wi-Fi router is
configured to work with its security functions at the time
of purchase. However, in consideration of security, it is
recommended that the security settings at the time of
purchase be changed.
For security function setting procedures, see this guide or
the user's manuals for the Wireless LAN devices.
- Use Wi-Fi router with the understanding that the Wireless
LAN security can be breached via special methods.
- Inquire with Customer Support to consult if you are unable
to configure the security settings.
- SoftBank cannot be held liable for WLAN security issues.
