Wireless LAN
Do not use wireless LAN near magnetic
devices such as electrical appliances or
AV/OA devices, or in radio waves.
•
Magnetism or radio waves may increase
noises or disable communications
(especially when using a microwave oven).
•
When used near TV, radio, etc., reception
interference may occur, or channels on
the TV screen may be disturbed.
•
If there are multiple wireless LAN access
points nearby and the same channel is
used, search may not work correctly.
Frequency band
The frequency band used by the WLAN device
is indicated on a label in the battery pack
recess of the FOMA terminal. The following
figure explains the indications on the label.
•
Available channels vary depending on the
country.
•
For use in an aircraft, contact the airline
beforehand.
•
For use of WLAN in a foreign country, the
country may have limitations on such as
locations where you can use it. Before
using WLAN in a foreign country, confirm
the available frequencies, laws,
regulations, and other conditions for use
of WLAN of the country.

Modulation scheme is the OFDM
system.
：
The estimated interference distance
is 40m or less.
：
The full band between 2400MHz
and 2483.5MHz is used and the

2.4 GHz device cautions
The operating frequency band of this
WLAN device is used by home electrical
appliances such as microwave ovens, as
well as industrial, scientific and medical
equipment including private radio
stations on factory premises for
identifying mobile units used in
manufacturing lines (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 the device, confirm that
private radio stations for identifying
mobile units, specified low power radio
stations and amateur radio stations are
not being operated nearby.
2. If the device causes harmful radio
interference to private radio stations for
identifying mobile units, immediately
change the frequency band or stop use,
and contact "docomo Information
Center" described on the last page of
this manual for crosstalk avoidance,
etc. (e.g. partition setup).
3. If the device causes radio interference
to specified low power radio stations or
amateur radio stations, contact
"General Inquiries" described on the last
page of this manual.
