CJAM-TA-TRAINSAFE ENDS UNAUTHORIZED CELL PHONE USE
CELL PHONE ALERT SYSTEM FOR TRAINS - TrainSafe is a solution to the growing problem of distracted driving
CellAntenna is a global leader in the detection, control and management of cell phone. A cell phone
for many has become an indispensible part of everyday life. Unfortunately, for some to the point of distraction.
Distracted driving is one of the major causes of highway fatalities in the US. To no one's surprise the use of
cell phones while driving has become a contributing factor to preventable accidents and many countries
around the world have imposed stiff fines as a deterrent.
The use of cell phones by drivers behind the wheel is unfortunately the tip
of iceberg as more workers in high risk jobs are distracted by texting and
WEB surfing. This includes operators of trains. A chilling reminder of what
can happen when operators of high speed trains are not 100% focused on
the job at hand is a MetroLiner crash in Chadsworth, CA in 2008.
people lost their lives when the train engineer was texting a message,
missed a red light signal and crash at full speed into another train.
railroad industry is committed to eliminating the use of cell phones
while operating a train.
CellAntenna has been
working with rail operators to
develop an affordable and
affective solution that can
serve as a real time deterrent
and save lives. The result of
this R&D effort has been
When the system's control unit is installed in the cab of a train, the use of any unauthorized cell phone is immediately
jammed in real time.
The TrainSafe unit's jamming module is only activated when the units detection module
passively detects a cell phone call (text), in range, attempting to connect with the cellular tower. This
reactive jamming concept eliminates any health concerns.
Small and highly sensitive antenna(s) are
connected to the TrainSafe unit and installed
inside of the operator's cab. When strategically
placed inside of the cab, they will detect an active
cell phone placing or receiving a call and
immediately activate the TrainSafe's jamming
module for a short period of time. This short burst
of RF energy on the cell phone carrier's downlink
frequencies is sufficient to block the connection
with the tower.
An Affective and Affordable deterrent that will prevent accidents
1) The TrainSafe System utilizes passive monitoring of
all the cellular carrier's uplink frequencies signal levels.
2) The TrainSafe unit, in passive detection mode, does
not transmit any RF signals
3) The detection module is triggered when the unit
senses the power level on the uplink frequency increase,
indicating a cellular handset in range is initiating
communications with the cellular carrier's tower/base
station. .(NOTE: In a moving train this communication
would happen frequently between an active handset and
the cellular carrier's towers as the cellular handset switches
from tower to tower along the way).
4) Antenna placement in the cab is important as the goal
is to detect cell phone use anywhere in the locomotive cab
5) Once the TrainSafe unit detects cell phone use a
jamming module is triggered and transmits a short burst of
RF energy on the carrier's downlink frequency bands. This
blocks communications between the handset and the tower
and the attempted call is never established.
6) This reactive jamming concept eliminates health and
safety concerns typically expressed with traditional "always
on" jamming systems
