Motorola MTS 4 TETRA Base Station	
Setting	new	standards	for	high	performance	and	reliability	
at	optimal	cost	for	mission	critical	communications
				   
						

							
Compact Design. Optimum Performance.
With	an	enhanced	receiver	sensitivity	performance,	MTS	4	delivers	at	least	
7	dB	better	than	the	standard	base	station.	With	a	high	transmit	power	
and	good	faded	sensitivity,	the	base	station	enables	significant	coverage	
improvement	 with	fewer	 sites,	without	 compromising	 on	the	 grade	 of	service.
The	MTS	4	offers	Multi-slot	Packet	Data	(MSPD)	over	an	entire	TETRA	
channel.	This	combines	up	to	4	individual	packet	data	channels	together,	using	
a	framing	rate	of	28.8	kbps.	MSPD	facilitates	faster	database	searches,	file	
and	image	transfers	amongst	others.	
Supporting	a	wide	range	of	Radio	Frequency	Distribution	Systems	(RFDS)	
configurations,	the	MTS	4,	a	four-carrier	base	station,	can	be	expanded	to	
eight	carriers	with	one	Rx/Tx	antenna.	MTS	4	supports	hybrid,	manual	and	
auto	tune	cavity	combiners.	
High Security. High Reliability.
For	increased	reliability,	MTS	4	offers	site	 controller	and	base	radio	(BR)	
redundancy.	For	instance	when	a	unit	is	unavailable,	it	auto-	switches	to	a	
backup	unit,	whilst	retaining	full	trunking	features	after	the	switch	over.
The	 MTS	 4	comes	 equipped	 with	a	sophisticated	 inbuilt	interference	 detection	
and	correction	mechanism.	The	system	automatically	replaces	the	interfered	
Main	Control	Channel	(MCCH)	in	operation	with	a	backup	channel.
The	MTS4	also	supports	Satellite	Transmission,	allowing	rapid	deployment	of	
the	base	station	in	crisis	situations.
Tough	and	extremely	reliable,	the	Motorola	MTS	4	is	a	high	specification,	full	
redundant	TETRA	base	station	offering	mission	and	business	critical	users	
the	ultimate	control	in	professional	communications.	Smaller,	lighter	and	even	
more	versatile	than	standard	base	station,	this	compact	base	station	offers	high	
performance	and	high	reliability	with	superb	cost	efficiency.

Flexible Design. Easy Maintenance. 	
Built	on	IP-based	architecture,	the	MTS	4	 is	
compatible	with	legacy	Motorola	TETRA	systems,	
making	it	easier	to	seamlessly	integrate	with	the	
existing	TETRA	systems.	It	allows	for	remote	
software	 configuration	 downloads	and	removes	 the	
need	for	costly	on-site	migration	and	maintenance.
The	base	radios	and	the	site	controller	are	also	
hot-
swapped	for	easy	maintenance.
The	MTS4	comes	with	a	front	access	and	top	
entry	for	easy	cabling	connection.	Furthermore,	
the	reduced	size	and	weight	of	the	base	station	
will	reduce	site	rental,	installation	and	maintenance	
costs.	It	also	provides	flexible	power	supply	
options	allowing	the	base	station	to	operate	in	AC	
or	DC	mode.	It	has	an	integrated	charging	output	
to	charge	batteries	during	AC	operation.
Next Generation. Investment Protection. 
Built	and	designed	for	future	communications	
needs,	the	MTS	4	is	upgradeable	to	support	future	
TETRA-2	High	Speed	Data	services.
Designed for High Redundancy.
The	MTS	4	has	two	E1	interfaces	for	easy	ring	
configuration	to	promote	high	redundancy.	The	
use	of	the	E1	ports	provides	redundant	connection	
in	the	event	of	failure,	ensuring	always-on	
connectivity.	It	allows	more	stations	to	be	added	
to	a	network	ring	structure.	A	ring	structure	can	
support	up	to	10	base	stations,	which	allows	the	
network	traffic	to	be	re-routed	in	the	event	of	a	link	
or	backhaul	failure.	
The	E1	interface	has	a	“drop	&	insert”	feature	
that	enables	flexible	and	resilient	connections	
to	the	switching	centre.	If	the	connection	to	the	
MSO	(Main	Switching	Office)	is	broken,	the	base	
station	intelligently	enters	into	local	trunking	mode,	
allowing	the	same	talkgroups	to	continue	voice	
operations	locally.
To	prevent	unauthorised	communications,	site	
monitoring	and	intrusion,	the	new	Motorola	base	
station	offers	high	level	of	security	including	
dynamic	and	static	Air	Interface	encryption	and	
End-to-End	Encryption	(E2EE).	In	addition,	the	base	
station	door	is	equipped	with	an	alarm	contact.
Normal	operation	is	possible	without	GPS.
