With the Lithos Digital Radio Repeater, long-range
robot operation does not mean a shortfall in performance.
Our digital repeater system effectively doubles your robot’s
range.
By itself, the Megalith
Digital Radio will easily allow one-mile line-of-sight
(LOS) operation and about 1000 feet in a crowded urban environment,
where buildings, cars and concrete can dramatically limit
signal power. Add a repeater and your operating range could
be as long as a two miles or 2000 feet in a crowded urban
environment.
Our Megalith Digital Radio
Repeater(TM)
is a stand-alone, self-powered digital radio that acts as
a relay, instantly re-transmitting all signals from your control
center to the robot. You get the same responsiveness and clarity
you expect from a digital signal with far greater range than
previously possible.
Featuring the same heavy duty construction--and
lightweight pricing--as our Megalith Digital Controller, the
Megalith Digital Radio Repeater is powered by a Lithium Ion
Battery for 8 hour run time.
It’s easy to use. Typically, your robot
can drop the repeater downrange then continue on to the scene.
Or, the repeater can be walked or driven by ATV/utility vehicle
to an optimal location. A Repeater Mobility Kit will be available
in 2012 that will allow the repeater to be a self-contained
mobile device, equiped with its own cameras.
Once the repeater is in place, the robot continues
its mission with line-of-sight performance in non-line-of-sight
environments.
CROWDED URBAN ENVIRONMENT
Illustrated below is a crowded urban environment that is
typical of a commercial or city setting. Buildings, cars,
trees, concrete and ambient radio interference can wreak havoc
on radio control systems. The Megalith radio command center
(red marker) easily controls a robot 1000 meters away (yellow
marker). Add a Megalith Repeater (green marker) to the system
and the range increases to 2000 meters (blue marker). Note
the repeater is placed LOS to the command center and the robot.
Different placement strategies will affect how the repeater
functions with the environment. Experimentation in training
is key to learning how best to use the system in any geographic
area.

EXAMPLE PERFORMANCE (crowded urban environment) (1 watt system)
Maximum range of radio without repeater = 1000 feet.
Maximum range with repeater = 2000 feet.
LINE-OF-SIGHT/OPEN COUNTRY ENVIRONMENT
Illustrated below is a typical open country setting in which
the Megalith console (red marker) is located so that there
is a clear line of sight to the receiver (yellow marker).
Line of sight trials have shown Megalith to have about one
mile effective range. With the addition of the Megalith
repeater (green marker), the range of the system increases
to about two miles (blue marker). Different placement strategies
will affect how the repeater functions with the environment.
Experimentation in training is key to learning how best to
use the system in any geographic area.
EXAMPLE PERFORMANCE (open country environment) (4 watt system)
Maximum range of radio without repeater = one mile.
Maximum range with repeater = two miles.
