Bluetooth Wireless Communications with
MobileMapper CE
The MobileMapper Beacon's primary method of communi-
cating coast guard beacon corrections to the MobileMapper
CE system is via an internal Bluetooth wireless communica-
tions module. This module is a license-free transceiver that
may be used in majority of countries throughout the world,
and operates at 2.4 GHz.
Bluetooth wireless communications is a convenient method
to communicate between electronic devices, eliminating the
need for you to connect a cable between the MobileMapper
Beacon and the MobileMapper CE.
The MobileMapper Beacon contains a Power Class 1 Blue-
tooth enabled device that is capable of a maximum range of
100 m with another class 1 device. If you are communicating
with another device that is a Power Class 2, your range will
be limited to a maximum of 10 m.
As Bluetooth transmits and receives at 2.4 GHz, it is a line
of sight system. This means that the MobileMapper Beacon
and the receiving device require a line of sight between them
in order to communicate. This is critical if you are using the
two devices toward their maximum operating rate from each
other. For example, you may use the MobileMapper CE
away from a vehicle, with the MobileMapper Beacon sitting
on the roof instead of wearing it. In this case, both devices
must be able to 'see' each other and be within the range limit.
However, when operating the MobileMapper Beacon near
the other device, such as the MobileMapper CE, you do not
need a line of sight between the two products. In this case,
reflected signals can be tracked off the ground with success.
You can also use a serial
data cable to communi-
cate with the
MobileMapper CE. The
original (non-CE)
MobileMapper receiver
is not Bluetooth-
enabled, and so you
must use a cable link.
This is available as an
option.
