Description
GPS, Wi-Fi, and
mobile networks
Uses GPS, Wi-Fi and mobile networks to identify
current location. Although current location can be
detected more accurately, the terminal consumes
much power of battery.
Wi-Fi and mobile
networks
Uses Wi-Fi and mobile networks to identify current
location.
GPS only
Uses GPS to identify current location.
Precautions on using GPS
• DOCOMO is not liable for any damage caused by abnormality of the
system.
• Note that DOCOMO shall have no liabilities for any purely economic loss
including those due to missing a chance to check the measurement
(communication) results because of external factors (including the
running out of the battery), such as a failure, malfunction, or any other
problems of the terminal or the power failure.
• You cannot use the terminal as a navigation device for an aircraft,
vehicle, and person. Note that DOCOMO shall have no liabilities
whatsoever even if you suffer damage or loss while performing a
navigation using the location information.
• You cannot use the terminal as a high-accuracy measurement GPS.
Note that DOCOMO shall have no liabilities whatsoever even if you suffer
damage or loss due to a deviation of the location information.
• GPS is a service operated by the USA Department of Defense, so the
GPS radio wave condition may be controlled (accuracy degraded, radio
wave suspended, etc.) for reasons of US national security. And, wave
conditions differ by satellite locations; therefore, positioning operations
in the same location under the same environmental conditions may not
yield the same result.
• Some wireless communications products (mobile phone, data detectors
and some others) block satellite signals and also cause instability of
signal reception.
• Some map displays based on location information (latitude/longitude
information) may be not accurate due to some countries' or regions'
regulations.
■
Where radio waves are difficult to receive
Note that radio waves may not be received or it may be difficult to
receive radio waves in the following conditions, since GPS uses radio
waves from a satellite.
• Inside or immediately under a building
• Inside a basement or tunnel, and below the ground or water
• Inside a bag or box
• Building area or residential area
• Inside or under a thick covering of trees
• Near a high-voltage cable
• In a car, inside a train compartment
• Bad weather such as heavy rain or snow
• When there are obstructions (people or objects) near the terminal
