Mobile Communications System
In the quiet aftermath of a disaster, a two-way radio is often the only sound that can
be heard. In disaster, radios become the foundation for emergency communications.
Motorola takes steps to ensure its radios and
communication infrastructures are prepared for disaster.
All Motorola equipment is designed to withstand
extraordinary punishment under the most demanding
conditions such as heat, cold, rain, smoke, and shock of a
fall. Motorola networks are designed to survive such
conditions and have proven this time after time.
No matter what the situation - a terrorist attack involving
weapons of mass destruction or a natural disaster such as
a hurricane - public safety networks must be designed to
withstand the most adverse conditions. However, even
the best communications components can be
compromised in a disaster. Existing systems may not be
able to meet the demands for interagency
communications and increased capacity. When systems
are victims of a disaster or are unable to meet mission -
critical needs, Motorola responds.
Motorola's interoperable Mobile Communications Systems are specially applied in
disaster areas to address terrorist events or hurricanes when the City of Miami's
("City") primary communications system requires backup or greater capacity and
additional communications coverage is needed. Together, they comprise a vital part
of Motorola's extensive portfolio of public safety and security solutions for mission -
critical integrated communications, information management, regional coordination,
and incident command.
Benefits to City of Miami by a Mobile Communications System
• Replace a Site: Loss of communications or Radio Frequency (RF) due to a
terrorist attack or hurricane force winds can cause the main or controlling
infrastructure to lose a tower and/or repeaters, which would prevent coverage at a
site. The Mobile Communications System features an 80-foot mast that provides
its own RF footprint to facilitate communications. This coverage is designed for
emergencies and is limited to the placement of the Mobile Communications
System and location to the subscriber radios.

• Deployable System: The Mobile Communications System is easy to set up,
equipping public safety teams with instant communication support when and
where it is needed. The Mobile Communications System will handle and
coordinate communication ability at a site due to acts of nature, restrictions in
location, technological, or conflict disaster, such as:
• Terrorist event
• Terrain (mountainous location site)
• Topographical limitations (tall trees, city skyscrapers)
• Existing inland roads
• Site limitations where power is a concern
• Existing RF two-way footprint (antenna limitations)
• Deployable System Statewide: The Mobile Communications System can be
relocated and used statewide to aid and support other Public Safety Agencies in.
disaster situations by reprogramming the RF Network System within the 800
MHz frequency range.
• Coordinated Interoperability: Motorola's deployable units are used to augment
existing networks to help coordinate interoperability events;

City Public Safety Agencies can use the Mobile Communications System in mission
critical situations — ranging from preparing for the worst, to providing a shared
network solution, to interoperability during disaster response.
The Mobile Communications System is a full power mobile transportable that offers
10-channel, 800 MHz Analog SMARTNET Single Site trunking solutions by
powering down the ten selected frequencies on the existing City system. The
equipment is enclosed in a weather resistant, four -bay cabinet with a maintained
environment controlled HVAC system. The trailer also contains an onboard generator
power, as well as shore power connections (if shore power is available), Motorola
specified R56 grounding, and TVSS. The trailer is designed with a mast that, once set
up, will extend to 80 feet.
A description of the components of the Analog SMARTNET Single Site system
infrastructure is best undertaken utilizing a block approach. The basic system
components are listed in the next subsection.

SMARTNET Trunking Equipment
Basic system infrastructure contains a 10-channel, 800 MHz Analog SMARTNET
Trunking System. Motorola proposes the following as part of the Mobile
Communications System fixed network equipment:
• (1) Main MTC 3600 SMARTNET Analog Central Controller with Software
Downgrade to Match Existing System Version
• (1) ML900 Laptop with ProComm Software for System Diagnostic and
Maintenance Control
• (10) 800 MHz 100-Watt QUANTAR Analog Repeaters with Software
Downgrade to Match Existing System Version
• (2) Auto -Tune 800 MHz Combiners
• (1) Auto -Quad 12-Port 800 MHz Multicoupler
♦ (2) Transmit and (1) Receive 800 MHz Antennas and Line Kits
• (1) UPS System for Backup MTC 3600 Controller and two to three QUANTARs
• (1) Set of Spares
MTC 3600 Main Central Controller
The MTC 3600 Central Controller is the central call -processing unit for the operation
of the trunked radio systems. This unit interfaces directly with the base station
repeaters and arranges the flow of communications between users. All of the system's
logic is contained on the plug-in cards within the central controller. These cards
contain programmable microprocessors capable of systematic processing of requests
for channels, automatic channel assignments, and talkgroups organization. The MTC
3600 will be programmed with its own unique system ID. The mobiles and portables
requiring access to the Mobile Communications System will require programming.
This will provide the City with the ability to deploy the Mobile Communications
System at the same time with the existing SMARTNET system. In order to run both
systems simultaneously, the City would power down the ten selected frequencies on
the existing City system.
Laptop for System Management Terminal Access
One (1) Laptop with ProComm software has been included in this proposal to provide
System Management Terminal (SMT) access, to allow users to manage system
diagnostics and maintenance control.

QUANTAR Base Station Repeaters
The 800 MHz Trunked QUANTAR Repeater Station contains all the logic and
control circuitry necessary to interface this top performance base/repeater station into
the trunked radio system. Each trunked repeater can handle system control data, as
well as voice traffic. One repeater is designated to transmit and receive the data
required to keep the system functional. This is referred to as the control. channel.
Transmit Combiner Network System
The antenna network system is designed using CELWAVE Auto -Tune transmitter
combiners. The auto -tuned cavity combiner tracks changes in base radio transmitters
and continuously optimizes itself. There will be two (2) transmitter combiners to
interface to the ten QUANTAR stations.
Receive Multicoupler Network System
The receive system is designed using a TxRx Systems, Inc. Auto -Quad Receiver
Multicoupler. This auto -quad 12-port receiver multicoupler is rack -mounted and
equipped with a narrowband pre -selector filter to further limit the multicoupler
bandwidth. The multicoupler is a very dependable, proven, and rugged device that
provides low noise and high gain for the site receivers.
RF Antenna Network System
Each PD 1610 Series CELWAVE Omnidirectional antenna proposed is specially
designed to meet requirements for repeater stations. This antenna is end -fed, utilizing
copper alloy radiating elements encased in a weatherproof, fibercast support pipe.
Minimal wind resistance conserves tower loading capacity.
All transmission lines and connector kits are manufactured using only the highest
quality materials. The transmission lines are flexible allowing for quick deployment
and long continuous lengths can be re -reeled numerous times for use in tactical or
restoration systems.
This proposal does not include a coverage reliability guarantee
Radio propagation is affected by many factors including, but not
limited to, site location, the antenna: network, equipment
characteristics, terrain, land clutter, and fabricated structures.
Powerware UPS System
Powerware 5125 provides advanced power management for PCs, workstations, and
servers. Available in rack -mount configuration, the Powerware 5125 is the most
flexible UPS in the 1-3 kVA power range. This UPS is designed to back up the MTC
3600 Controller and two to three QUANTAR Stations in a rack -mount layout.

Console/Microwave Link
Motorola has included as part of this proposal a wireless link between the Mobile
Communications System and the City's Police Department. The following equipment
is included and is described in further detail in this subsection:
• (2) ADTRAN TRACER 6200 5.8 GHz RF Link
• (2) 2-foot Dishes
• (2) ADTRAN ATLAS 550 Channel Banks
• (1) 2-Card Cage Central Electronics Bank (CEB) with Software Downgrade to
Match Existing System Version
• (1) Set of Spares
ADTRAN ATLAS 550
The ATLAS 550 is a modular, highly scalable platform that provides robust solutions
for the wide -area communication needs of small -to -medium corporations and
network access providers. It contains a high-performance CPU and powerful
communications drivers that support applications such as frame relay, dial backup,
and PPP (point-to-point protocol). The ATLAS 550 will be used to multiplex the
4-wire audio from each of the QUANTAR stations and the Trunked Input/Output
Interface Module (TIMI) Link into a single Ti.
ADTRAN TRACER 6200
The TRACER 6000 series wireless modular radio system provides license -free
scalable connectivity for service providers and corporate networks. The TRACER
6000 series radios provide carrier class point-to-point connectivity for up to 30 miles
in the 5.8 GHz frequency band. The distance depends on the height of antennas,
terrain, and the diameter of the dish. The maximum mounting height of the dish on
the trailer tower is 40 feet.
The TRACER 6200 provides an RF connectivity link to the City's Police Department
Headquarters. The TRACER 6200 system is designed for operation in the license -free
5.725 GHz to 5.850 GHz industrial, scientific, and medical (ISM) band. Radio wave
propagation in this band exhibits microwave characteristics that are ideally suited for
point-to-point, line -of -sight communications. Line -of -sight requires that the
transmitting antenna and receiving antenna are able to "see" each other, and that the
straight-line path between the two antennas is free of obstructions such as buildings,
trees, mountains, and in loner paths, even the curvature of the earth. For maximum
signal strength, the area around the visual line -of -sight where microwave signals
reflect (Fresnel zone) must also be free of obstructions.
