Frequency Bands
Wi-Fi router Wi-Fi (wireless LAN)/Bluetooth
are as shown below.
2.4 : Radio equipment that uses the 2.4 GHz band.
DS4 : An interference distance of up to 40 m assumed for the
DS-SS system.
OF4 : An interference distance of up to 40 m assumed for the
OFDM system.
FH4 : An interference distance of up to 40 m assumed for the
FH-SS system.
XX8 : Modulation scheme assumes an interference distance of
within 80 m for other systems.
: This means that the product uses all frequency
bands and is incapable of avoiding the frequency band for
mobile device identification equipment.

Wi-Fi (Wireless LAN)
Wi-Fi (wireless LAN) exchanges information using radio
waves, and allows you to freely establish a LAN connection
if you are within an area where radio waves reach. However,
communication without appropriate security settings may
allow communication to be intercepted by malicious parties.
It is recommended to make security settings, and is at your
discretion.
・Do not use Wi-Fi where there is an electromagnetic field such
as near electrical appliances or AV/OA devices.
- Magnetic fields may increase electrical noise or may affect
communication (especially when using a microwave oven).
- It may interfere with reception if near a TV, radio, etc., or
the TV screen may become unviewable.
- If multiple Wi-Fi (wireless LAN) access points using the
same channel are in proximity, handset may not detect access
points correctly.
・Use of Wi-Fi (wireless LAN) is restricted in some countries/
regions. Check the laws and regulations of the country/region
before using handset abroad.
・Cautions on Using 2.4 GHz Devices
・Wi-Fi devices use the same frequency band used by household
appliances (microwave ovens) and industrial/scientific/
medical equipment as well as by in-place radio stations
(requiring a license) and specific low-power radio stations
(not requiring a license) for mobile identification as used in
production lines, and by amateur radio stations (requiring a
license).
1. Before using handset, check that no in-place radio stations
for mobile identification, specific low-power radio stations,
or amateur radio stations are in operation nearby.
2. If use of handset causes interference with regard to an in-
place radio stations for mobile identification, immediately
change the usage frequency, or discontinue use.
3. If handset is otherwise a cause of interference with regard
to specific low-power radio stations for mobile identification
or amateur radio stations and assistance is required, contact
a SoftBank Shop or
"Customer
Service."
・Cautions on Using 5 GHz Devices
Wi-Fi router uses 5 GHz frequency band.
Wi-Fi router uses the following channels.
・- W52 (5.2 GHz band / 36, 40, 44, 48 ch)
- W56 (5.6 GHz band / 100, 104, 108, 112, 116, 120, 124,
128, 132, 136, 140 , 144 ch)
Use of the 5.2 GHz band outdoors is prohibited.
・Bluetooth
Devices and Interference
®
Bluetooth
and Wi-Fi (wireless LAN) use the same frequency
®
band. Their use at the same time may cause interference and
affect communication speed or disrupt the connection.
Distance the Bluetooth
and Wi-Fi (wireless LAN) devices, or
®
power off and discontinue using either device.
