PLEASE READ THESE SAFETY PRECAUTIONS!
RF Energy Health Hazard
The radio equipment described in this guide uses radio frequency transmitters. Although the
power level is low, the concentrated energy from a directional antenna may pose a health hazard.
Do not allow people to come closer than 119 cm (47.2) to the front of the antenna while the
transmitter is operating. The antenna must be professionally installed on a fixed-mounted
outdoor permanent structure to provide separation from any other antenna and all persons as
detailed in this manual.
Protection from Lightning
Article 810 of the US National Electric Department of Energy Handbook 1996 specifies that radio
and television lead-in cables must have adequate surge protection at or near the point of entry to
the building. The code specifies that any shielded cable from an external antenna must have the
shield directly connected to a 10 AWG wire that connects to the building ground electrode.
Warning – This is a Class A product
Warning – This is a Class A product. In a domestic environment this product may cause radio
interference in which case the user may be required to take adequate measures.
Warning – Turn off all power before servicing
Warning – Turn off all power before servicing this equipment.

2.1 About This Manual
This manual is written for those who are involved in the “hands-on” installation of the
MDS FOUR.9 Series Digital Transceiver, such as installation technicians, site evaluators, project
managers, and network engineers. It assumes the reader has a basic understanding of how to
install hardware, use Windows based software, and operate test equipment.
The MDS FOUR.9 Series includes a Software Defined Indoor UnitTM (SDIDUTM) and outdoor unit
(ODU). The SDIDUTM is a product and trademark of CarrierComm.
2.2 Introduction
The Microwave Data Systems family of digital radios provides high capacity transmission,
flexibility, features, and convenience for wireless digital communications networks. The
Microwave Data Systems digital point-to-point radios represent a new microwave architecture
that is designed to address universal applications for both PDH and SDH platforms. This
advanced technology platform is designed to provide the flexibility to customers for their current
and future network needs.
The Microwave Data Systems radio family is based upon a common platform to support a wide
range of network interfaces and configurations. It supports links for 16 x E1/T1, 100BaseTX
Ethernet, and DS-3/E-3/STS-1 (optional, consult factory for availability). The radio family is
spectrum and data rate scalable, enabling service providers or organizations to trade-off system
gain with spectral efficiency and channel availability for optimal network connectivity. The
Microwave Data Systems digital radio family enables network operators (mobile and private),
government and access service provides to offer a portfolio of secure, scalable wireless
applications for data, video, and Voice over IP (VoIP).
The MDS FOUR.9 Series digital radio family operates in the FCC Public Safety Band of 4.940 to
4.990 GHz, which is generically referred to as the “4.9 GHz band.” The MDS FOUR.9 Series
supports three types of user data payload connectivity as follows:
•
100Base-TX intelligent bridging between two locations without the delay and expense of
installing cable or traditional microwave.
•
Scalable Ethernet capability of 25 and 50 Mbps is included. These scalable radios provide
LAN connectivity and offer performance trade-offs between operational bandwidths, data
rates, and distance.

16E1 or T1 for cellular backhaul, enterprise voice applications and voice network redundancy
For customers such as cellular carriers requiring backhaul and backbone extension as well
as service providers requiring network redundancy, new Points of Presence (POPs), and last mile
access, the MDS FOUR.9 Series radio is a cost effective alternative to leased lines with carrierclass quality of performance. The MDS FOUR.9 Series is a cost effective solution to meet the
growing demand for enterprise Local Area Network (LAN) connectivity between buildings and
campuses as well as service providers requiring reliable products for infrastructure expansion,
extending Metropolitan Area Network (MAN) fiber access, and network redundancy.
The MDS FOUR.9 Series includes integrated Network Management functionality and design
features enabling simple commissioning when the radio network is initially set up in the field at
the customer’s premises. Furthermore, a highlight of MDS radio products is scalability and the
capability to support a ring-type architecture. This ring or consecutive point radio architecture is
self-healing in the event of an outage in the link and automatically re-routes data traffic, thereby
ensuring that service to the end user is not interrupted.
The MDS FOUR.9 Series is composed of a Software Defined Indoor UnitTM (SDIDUTM) and
Outdoor Unit (ODU). It supports 1+0 and 1+1 protection and ring architectures in a single 1 RU
chassis. The modem and power supply functions are supported using easily replaceable plug-in
modules. An additional feature of the SDIDUTM is provision for a second plug-in modem/IF
module to provide repeater or east/west network configurations.
The overall architecture consists of a single 1RU rack mount Software Defined Indoor Unit
(SDIDUTM) with a cable connecting to an Outdoor Unit (ODU) with an external antenna.

Power Supply Input
DC Input
-48 VDC
-48v (Isolated Input); 2-pin captive power connector. The unit
requires an input of -48 volts dc ±10% at the front panel DC
Input connector. The total required power is dependent on
the option cards and protection configuration (1+0, 1+1). The
SDIDUTM front panel power connector pin numbering is 1
through 2, from left to right, when facing the unit front panel.
Pin 1 is the power supply return and is connected to unit
chassis ground internally. Pin 2 should be supplied with a
nominal -48 V dc, with respect to the unit chassis (ground).
A ground-isolated supply may be used, provided it will
tolerate grounding of its most positive output.
The recommended power input is -44 to -52 V dc at 2 Amps
minimum. It is recommended that any power supply used be
able to supply a minimum of 100 Watts to the SDIDUTM.
A mating power cable connector is supplied with the
SDIDUTM. It is a 2-pin plug, 5 mm pitch, manufactured by
Phoenix Contact, P/N 17 86 83 1 (connector type MSTB
2,5/2-STF). This connector has screw clamp terminals that
accommodate 24 AWG to 12 AWG wire. The power cable
wire should be selected to provide the appropriate current
with minimal voltage drop, based on the power supply
voltage and length of cable required. The recommended
wire size for power cables under 10 feet in length supplying
-48 Vdc is 18 AWG.
The SDIDUTM supplies the ODU with all required power via
the ODU/SDIDUTM Interconnect cable. The SDIDUTM does
not have a power on/off switch. When DC power is
connected to the SDIDUTM, the digital radio powers up and is
operational. There can be up to 204 mW of RF power
present at the antenna port (external antenna version). The
antenna should be directed safely when power is applied.

2.5 System Description
The overall digital radio architecture consists of a single 1RU rack mount Software Defined Indoor
UnitTM (SDIDUTM) with a cable connecting to an Outdoor Unit (ODU). The 4.9 GHz ODU is
designed for use with an external antenna only. This SDIDUTM /ODU architecture is
advantageous when compared to a single IDU with external mount antenna, since supporting a
signal of 4.9 GHz from the IDU rack to the antenna will result in significant signal degradation,
which would require expensive coaxial cable or waveguide.
Figure 2-4 shows the SDIDUTM and interfaces from a functional point of view. The functional
partitions for the I/O, Modem/IF, and power supply modules are shown. The SDIDUTM comes
with the standard I/O capability that can be upgraded. In addition, the Modem/IF function is
modular. This allows the addition of a second Modem to support protection or ring architectures.
The power supply is similarly modular.

The ODU RF Up/Down Converter card provides the interface to the antenna. The transmit
section up-converts and amplifies the modulated Intermediate Frequency (IF) of 350 MHz from
the IF Processor and provides additional filtering. The receive section down converts the
received signal, provides additional filtering, and outputs an IF of 140 MHz to the IF Processor.
The 64-QAM Modem performs the modulation and demodulation of the payload and forward error
correction using advanced modulation and coding techniques. Using all-digital processing, the
64-QAM Modem uses robust modulation and forward error correction coding to minimize the
number of bit errors and optimize the radio and network performance. The 64-QAM Modem also
scrambles, descrambles and interleaves/deinterleaves the data stream in accordance with
Intelsat standards to ensure modulation efficiency and resilience to sustained burst errors. The
modulation will vary by application, data rate, and frequency spectrum. The highest order
modulation mode supported is 64 Quadrature Amplitude Modulation (QAM). Table 2-5
summarizes the TCM/convolutional code rates for each modulation type supported by the MDS
FOUR.9 Series.

The major functions of the SDIDUTM can be summarized as follows:
•
I/O Processing – The SDIDUTM comes with a standard I/O capability that includes support for up to
16xT1/E1 and 2x100Base-TX user payloads, 2x100Base-TX for SNMP, and voice orderwire. In
addition, option cards for DS-3/E3/STS-1, 1-2 x STM-1/OC-3, and 4xDS-3/E3/STS-1 may be
added. The SDIDUTM architecture is flexible and allows for the addition of other I/O types in the
future.
•
Switch/Framing – The SDIDUTM includes an Ethernet Switch and a proprietary Framer that are
designed to support 1+1 protection switching, ring architecture routing, and overall network control
functions.
•
Network Processor – The SDIDUTM includes a Network Processor that performs SNMP and
Network Management functions.
•
Modem/IF – The SDIDUTM Modem performs forward-error-correction (FEC) encoding, PSK/QAM
modulation and demodulation, equalization, and FEC decoding functions. The IF chain provides a
350 MHz carrier, receives 140 a MHz carrier, processes OOK telemetry, and provides –48V
power. Two modems can be used for 1+1 protection or ring architectures.
•
Power Supply – The SDIDUTM power supply accepts -48 Vdc and supplies the SDIDUTM and ODU
with power. A second redundant power supply may be added as an optional module.
The Modem Processor and its associated RAM, ROM, and peripherals control the digital and analog
Modem operation. It also provides configuration and control for both the IF and I/O cards. The

SDIDUTM interfaces with the ODU to receive and provide modulated transmit and receive
waveforms.
The SDIDUTM also provides the physical interface for the user payload and network management.
In transmit mode, the Framer merges user payload with radio overhead-encapsulated network
management data. This combined data stream is transmitted without any loss of user bandwidth.
In the receive mode, the Framer separates the combined data stream received from the 64-QAM
Modem. The SDIDUTM supports Scalable Ethernet data rates, such as 25 or 50 Mbps via the
100BaseT data interface port. The SDIDUTM provides network management data on 10 Mbps
ports accessible via the 10/100BaseTX port. The Central Processor Unit (CPU) provides the
embedded control and network element functionality of the NMS. The CPU also communicates
with other functions within the SDIDUTM for configuration, control, and status monitoring.
In Ethernet models, the payload of each user Ethernet data packet and all T1 can be encrypted
using an AES encryption algorithm. In addition, the encryption engine is re-seeded with a new,
randomly generated key stream every 10 seconds, in order to provide enhanced security. The
initial key is based off of a pass phrase entered into each MDS FOUR.9 Series unit by the
network administrator. Consult factory for the availability of this encryption function.
The power supply converts -48 Vdc to the DC voltage levels required by each component in the
system.
2.6 Consecutive Point Architecture
The consecutive point network architecture is based upon the proven SONET/SDH ring.
Telecommunications service providers traditionally use the SONET/SDH ring architecture to
implement their access networks. A typical SONET/SDH network consists of the service
provider’s Point of Presence (POP) site and several customer sites with fiber optic cables
connecting these sites in a ring configuration (see Figure 2-5). This architecture lets providers
deliver high bandwidth with high availability to their customers.

User Reference and Installation Guide
2-16
Figure 2-5. Ring Configuration.
SONET/SDH rings are inherently self-healing. Each ring has both an active path and a standby
path. Network traffic normally uses the active path. Should one section of the ring fail, the network
will switch to the standby path. Switchover occurs in seconds. There may be a brief delay in
service, but no loss of payload, thus maintaining high levels of network availability.
The consecutive point architecture implemented in the MDS FOUR.9 Series Digital Radio family
is based on a point-to-point-to-point topology that mimics fiber rings, with broadband wireless
links replacing in-ground fiber cable. A typical consecutive point network consists of a POP and
several customer sites connected using MDS FOUR.9 Series units. These units are typically in a
building in an east/west configuration. Using east/west configurations, each unit installed at a
customer site is logically connected to two other units via an over-the-air radio frequency (RF) link
to a unit at an adjacent site.
Each consecutive point network typically starts and ends at a POP. A pattern of wireless links and
in-building connections is repeated at each site until all buildings in the network are connected in
a ring as shown in Figure 2-6. . For 2 x 1+0 and 2 x 1+1 nodes payload and NMS connections
need to be jumpered between two SDIDUTMs. For 1 x 2+0 nodes, there is no need for jumpers as
there is a single SDIDUTM. For SDH or SONET payloads, the configuration is similar but an
external add/drop mux and a second SDH/SONET interface card are required.

2.7 2 + 0 (East-West) Configuration
The SDIDUTM supports an east/west, or 2+0, configuration that allows a consecutive point
architecture to be achieved with only a single 1 RU chassis at each location. In this configuration
the SDIDUTM contains two modems supplies and may contain two power supplies. One modem
is referred to as the west modem and the other as the east modem. The SDIDUTM is connected
to two ODUs, one broadcasting/receiving in one direction of the ring architecture and the other
broadcasting/receiving in the other as shown in Figure 2-7.

2.8 1+1 Protection
The MDS FOUR.9 Series supports 1+1 protection as an option for a critical link. In this
configuration, protection is provided in a single 1 RU chassis. The SDIDUTM contains two power
supplies and two modems. The power supply, ODU, IF/telemetry and modem are protected. The
digital framing and LIUs are not. One modem is referred to as the west modem and the other as
the east modem. 1+1 protection can be run in two modes called diversity and non-diversity.
In diversity mode, the link between each pair of modems is the same, as shown in Figure 2-8,
providing complete redundancy. This arrangement requires bandwidth for both links and noninterference between the links, but it provides hitless receive and transmit switching. The
SDIDUTM supports both frequency and spatial diversity. In frequency diversity, two frequencies
are used. In spatial diversity, two non-interfering paths are used. In either case, the proprietary
framer chooses the best, or error-free, data stream and forwards it to the Line Interface Units
(LIUs).

Data Interfaces
The I/O card has 2x100BaseTX interfaces that can be configured as either primary payload, or
secondary wayside channels. The Over-the-air channel has a data-bandwidth capacity that is set
by the frequency-bandwidth, modulation, and coding. The data-bandwidth may be allocated to
various I/O card interfaces, including 155.52 Mbps for STM-1, 2 Mbps per E1, up to 100 Mbps
Ethernet, and up to 1 Mbps NMS. Only up to 100 Mbps of data-bandwidth may be allocated for
either net data, and the two I/O card 100BaseTX interfaces will share that 100 Mbps databandwidth.
There is also an option mini-I/O card, which provides STM-1 Optical/OC-3 or STM-1 Electrical
interfaces. The optical interface is single mode at 1300 nm. Consult factory for availability of
Mini-IO STM-1/OC-3 Module.
2.11
Power Management
RF power management is a radio design feature that controls the power level (typically expressed
in dBm) of the RF signal received from a transmitter by a receiver. The traditional goal of power
management is to ensure that the RF signal at a receiver is strong enough to maintain the radio
link under changing weather and link conditions.
Traditional power management techniques such as Constant Transmit Power Control (CTPC)
and Automatic Transmit Power Control (ATPC) transmit at a high power level to overcome the
effects of fading and interference. However, these techniques continue to operate at a higher
© 2006 Microwave Data Systems Inc. All Rights Reserved.
MDS FOUR.9 Series

User Reference and Installation Guide
2-22
power level than needed to maintain the link in clear weather. Because transmit power remains
high when the weather clears, the level of system interference increases.
Radios operating at high transmit power will interfere with other radios, even if the interfering
source is miles away from the victim. High interference levels can degrade signal quality to the
point that wireless radio links become unreliable and network availability suffers. The traditional
solution to system interference is to increase the distance between radios. However, the resulting
sparse deployment model is inappropriate for metropolitan areas.
In response to the need for a high-density deployment model the MDS FOUR.9 Series use a
unique power control technique called AdTPC. AdTPC enables MDS FOUR.9 Series units to
transmit at the minimum power level necessary to maintain a link regardless of the prevailing
weather and interference conditions. The MDS FOUR.9 Series is designed and manufactured to
not exceed the +30 dBm maximum power allowed. The purpose of power management is to
minimize transmit power level when lower power levels are sufficient. AdTPC also extends the
concept of power management by controlling not only the power (dBm) of the RF signal, but its
quality (signal-to-noise ratio) as well.
In contrast to ATPC, the AdTPC technique dynamically adjusts the output power based on both
the actual strength and quality of the signal. Networked MDS FOUR.9 Series units constantly
monitor receive power and maintain 10-12 BER performance under varying interference and
climate conditions. Each MDS FOUR.9 Series unit can detect when there is a degradation in the
received signal level of quality and adjust the transmit power level of the far-end MDS FOUR.9
Series unit to correct for it.
AdTPC provides maximum power in periods of heavy interference and fading and minimum power
when conditions are clear. Minimal transmit power reduces potential for co-channel and adjacent
channel interference with other RF devices in the service area, thereby ensuring maximum
frequency re-use. The resulting benefit is that operators are able to deploy more MDS FOUR.9
Series units in a smaller area.

MDS FOUR.9 Series Software and
Network Management
All of the MDS FOUR.9 Series parameters are accessible in three ways:
1. Using a standard web-browser via HTTP to access the built in webserver.
2. Via SNMP using the fully featured MIB, allowing for automation of data collection and
network management.
3. Via a command line client accessible from a terminal client connected to the serial port, or
telnet over the NMS Ethernet.
The GUI, SNMP, and CLI control are discussed in the MDS FOUR.9 Series User Interface
Manual.

3.4 PRE-INSTALLATION NOTES
It may be useful to gain familiarity with the MDS FOUR.9 Series via back-to-back bench testing
prior to final installation. We highly recommend installation of lightning protectors on the
ODU/SDIDUTM Interconnect Cable to prevent line surges from damaging expensive components.
Back-to-back bench testing prior to final installation is highly recommended in order to gain
familiarity with the product. The following additional equipment is required for back-to-back
testing:
•
Low-loss cables, N-male connectors on ODU interfaces.
•
Two inline RF attenuators, 30 dB each, rated for ODU frequency.
The SDIDUTM and ODUs must be configured in an operational configuration and set-up as shown
in Figure 3-2. When equipment is connected in operational configuration, no errors should be
reported on the front panel.

3.6.2 Site Evaluation Process
The following steps must be completed to perform a successful site evaluation. Each step in the
process is detailed in the following subparagraphs:
•
Ensure RF Safety compliance: Ensure that appropriate warning signs are properly placed
and posted at the equipment site or access entry. For a complete list of warnings, refer
the Safety Precautions listed at the beginning of this manual.
•
Ensure Compliance with Laws, Regulations, Codes, and Agreements: Ensure that any
installation performed as a result of the site evaluation is in full compliance with applicable
federal and local laws, regulations, electrical codes, building codes, and fire codes.
•
Establish Radio Line of Sight between MDS FOUR.9 Series Radios: The most critical
step in conducting a site evaluation is confirming a clear visual and radio Line of
Sight (LOS) between a near MDS FOUR.9 Series Radio and a far MDS FOUR.9
Series Radio. If LOS does not exist, another location must be used.
MDS FOUR.9 Series Radios in a link must have a clear view of each other, or visual “line
of sight”. Binoculars may be used evaluate the path from the desired location of the near
MDS FOUR.9 Series Radio to the desired location of the far MDS FOUR.9 Series Radio.
To confirm Line of Sight:
Ensure that no obstructions are close to the transmitting/receiving path. Take into
consideration trees, bridges, construction of new buildings, unexpected aerial traffic,
window washing units, etc.
Ensure that each MDS FOUR.9 Series can be mounted in the position required to
correctly align the MDS FOUR.9 Series with its link partner.
MDS FOUR.9 Series Radios must also have a clear radio line of sight. If a hard object,
such as a mountain ridge or building, is too close to the signal path, it can damage the
radio signal or reduce its strength. This happens even though the obstacle does not
obscure the direct, visual line of sight. The Fresnel zone for a radio beam is an elliptical
area immediately surrounding the visual path. It varies in thickness depending on the
length of the signal path and the frequency of the signal. The necessary clearance for the
Fresnel zone can be calculated, and it must be taken into account when designing a
wireless links.
As shown in the picture above, when a hard object protrudes into the signal path within
the Fresnel zone, knife-edge diffraction can deflect part of the signal and cause it to reach
the receiving antenna slightly later than the direct signal. Since these deflected signals
are out of phase with the direct signal, they can reduce its power or cancel it out

altogether. If trees or other 'soft' objects protrude into the Fresnel zone, they can
attenuate (reduced the strength of) a passing signal. In short, the fact that you can see a
location does not mean that you can establish a quality radio link to that location.
Microwave Data Systems provides a link planner spreadsheet that calculates the Fresnel
ratio and helps determine link feasibility. Contact your technical support representative
for a copy of the spreadsheet.

interference analysis needs to be performed by an RF engineer. The specific information
required for each transmitter and receiver includes the following:
•
Transmitting and/or receiving frequency
Type of antenna
Distance from MDS FOUR.9 Series ODU (horizontal and vertical)
Polarity (horizontal or vertical)
Transmit power level
Antenna direction
Measure the Link Distance: The two ways to measure link distance are as follows:
GPS: record the latitude and longitude for the near and far MDS FOUR.9 Series ODU
sites and calculate the link distance. Record the mapping datum used by the GPS
unit and ensure the same mapping datum is used for all site evaluations in a given
network.
Range finder: measure the link distance (imperial or metric units may be used).
Once the link distance has been measured, verify that the link distance meets the
availability requirements of the link. Microwave Data Systems has created a spreadsheet
tool that calculates the link availability based on the details of the link. The Microsoft Excel
spreadsheet is available on internet, at http://www.microwavedata.com/, and is shown on
the following page. The following parameters should be entered (items in yellow):
•
Operating Frequency: Enter 4900
•
Transmit Antenna Gain: Enter the gain of the external antenna.

•
Receive Antenna Gain: Enter the gain of the external antenna if used.
•
Link Distance: Enter distance in miles or kilometers (must select the correct units: miles or
kilometers)
•
Fresnel Clearance Ratio: This is a factor indicating the radio line of sight. A clear radio
line of site has a fresnel clearance ratio of +0.60. As the curvature of the earth or other
obstacles degrade the radio line of sight, the ratio can drop to –1. A separate spreadsheet
is provided to calculate the appropriate ratio. In this spreadsheet the path length, tower
heights and heights of any obstructions or ridges in the path of the link are entered.
•
Climate Factor: Enter 0.1 for dry, 0.25 for average and 0.5 for humid environments
•
Terrain Factor: Enter 0.25 for mountainous, 1 for average, and 4 for smooth (water)
•
Determine the Length of Interconnect Cable from ODU to SDIDUTM: The primary
consideration for the outdoor interconnect cable from the ODU to SDIDUTM is the distance
and route between the ODU and SDIDUTM. Maximum cable lengths are listed in Table

3.6.3 Critical System Calculations
3.6.3.1
Received Signal Level (RSL) and Link Budget
The received signal level (RSL) can be estimated using the following formula:
RSL (dBm) = PTX + GTX ANT – LPath + GRX ANT
Where: PTX is the transmitter output power (in dBm)
GTX ANT is the gain of the transmit antenna (in dB)
GRX ANT is the gain of the receive antenna (in dB)
LPath is the Path loss, defined by:
LP (dB) = 36.6 + 20log10(F*D)
Where: F is the Frequency in MHz (4900 GHz), D is the Distance of path in miles
This link budget is very important in determining any potential problems during installation.
expected RSL and measured RSL should be close (+/- 5 to 10 dB)
3.6.3.2
The
Fade Margin Calculation
The fade margin is the difference between the actual received signal and the MDS FOUR.9
Series Radio’s threshold for the modulation mode selected. The fade margin can be used to
determine availability and should be at least 10 dB.

3.6.3.3

Availability Calculation
Availability of the microwave path is a prediction of the percent of time that the link will operate
without producing an excessive BER due to multipath fading. Availability is affected by the
following:
•
Path length
•
Fade margin
•
Frequency
•
Terrain (smooth, average, mountainous, valleys)
•
Climate (dry, temperate, hot, humid)
Depending on the type of traffic carried over the link and the overall network design redundancy,
fade margin should be included to support the desired availability rate. Critical data and voice
may require a very high availability rate (99.999% or 4.9 minutes of predicted outage per year).
To improve availability, the fade margin can be increased by shortening the path length,
transmitting at a higher power level, or by using higher gain antennas.
Availability can be computed using the following formula, which is known as the Vigants Barnett
Method.
Availability = 100 × (1 – P)
P = 2.5 × 10-9 × C × F × D3× 10(-FM/10)
Where F is the frequency in MHz (4900 MHz)
D is the distance in miles
FM is the fade margin in dB
C is the climate/terrain factor as defined below:
Humid/Over Water: C = 4 (worst case channel)
Average Conditions: C = 1
Dry/Mountains: C = 0.25 (best case channel)
Example: Assume 21 dB fade margin, over 5 miles with average climate/terrain, at 4.9 GHz. The
availability comes out to be 99.9986. This corresponds to the link being unavailable for 7.6
minutes per year.
3.6.4 Frequency Plan Determination
When configuring MDS FOUR.9 Series units in a point-to-point or consecutive point configuration,
careful engineering of the MDS FOUR.9 Series frequency plans and antenna locations should be
performed in order to minimize potential interference between nearby radios. Nearby radios
should operate on different frequencies, transmitting in the same band (high side or low side).

MDS FOUR.9 Series
05-4561A01, Rev. A
User Reference and Installation Guide
3-14
When designing multi-radio configurations, antenna size, antenna polarization, and antenna
location are critical.
The frequency plan must be selected based on desired data rate and expected link conditions. In
a high interference environment or with lower gain antennas, higher bandwidth, more robust
modulation formats must be employed. The available frequency plans are illustrated in Figure
3-3.
The channel assignments shown in the figures correspond to the channel numbers entered via
the graphical user interface (GUI) or SNMP.

The ODU must be used with an external antenna.
adequate link performance for most applications.
The choice of antenna should provide
Larger antennas have the advantage of providing narrower beamwidths and high isotropic gain,
which yields better link performance (higher fade margin, better availability), and improves
immunity to spatial interference (due to the smaller beamwidths). However, larger antennas are
more costly to purchase and install than smaller antennas and in some cases, they require
special equipment for installation due to narrower beamwidths. They are also more easily
affected by wind.
Only directional antennas can be used with MDS FOUR.9 Series radios. Consult factory for
antenna manufacturer options.

2. Determine the length of cable required. Allow three extra feet on each end to allow for strain
relief, as well as any bends and turns.
3.6.6 ODU Transmit Power Setup
Setting the ODU transmit power is conditional on the band and application. The installer of
this equipment is responsible for proper selection of allowable power settings. If there are
any questions on power settings refer to your professional installer in order to maintain
the FCC legal ERP limits.
The SDIDUTM employs spectrally efficient shaped Quadrature Amplitude Modulation (QAM). This
waveform is not a constant envelope waveform. Therefore, the average power and peak power
are different. The difference in peak and average power depends on the constellation type and
shaping factor, where spectral efficiency such as more constellation points or lower shaping
factor leading to peak powers higher than average powers. The peak power is typically 5-7 dB
greater than the average power in the SDIDUTM, and never exceeds 7 dB. Regulatory
requirements are usually based on peak EIRP which is based on peak power and antenna gain.
3.6.6.1
4.9 GHz Band
In the 4.9 GHz Public Safety band the peak EIRP (Effective Isotropic Radiated Power) is limited
to +57.8 dBm at the antenna for bandwidths up to 15 MHz and is reduced for narrower
bandwidths in accordance with FCC Part 90.1215. The ODU must therefore be adjusted so that
the station does not exceed the allowable limit.
The installer is responsible during set up of transmit power to not exceed FCC limits on
transmission power. These maximum power levels are provided in Table 3-2 for various antenna
configurations, along with the operational bandwidths.
Note that though regulatory limits are stated in terms of peak power, the system transmit power
levels are calibrated as averaged power readings. Average power is used for link calculations.
Therefore the levels provided in table 3-2 are average power levels that have been certified to
correspond with the maximum peak EIRP allowed.
EIRP is calculated for link budget with external antennas as,
EIRP(avg) dBm = External Antenna Gain (dBi) + 23 dBm
3.6.6.1.1
ODU with External Antenna
When using external antennas with gains greater than 23 dBi, the transmit power must be
reduced in dB from that given in Table 3-1 by the antenna gain difference above 23 dBi for the
mode that is being used.
For example, using a 6 foot dish antenna with 37 dBi gain, the output power would be dropped by
Antenna Gain (External) – 23 dBi = Antenna Gain Difference
37.6 dBi – 23 dBi = 14.6 dB

MDS FOUR.9 Series
05-4561A01, Rev. A
User Reference and Installation Guide
3-16
For mode 100FE1 (single channel configuration with 30MHz emission bandwidth) the power
would be lowered from
Tx Power – Antenna Gain Difference = Tx Power (External Ant)
+5 dBm – 14.6 dB = -9.6 dBm (-10 dBm).
Table 3-1 also presents transmit power settings for various antenna dish sizes.
For link budget, EIRP(Avg) dBm = 37 dBi + Tx Power Setting (dBm).

* Note: Many antenna manufacturers rate antenna gain in dBd (dB referred to a dipole antenna)
in their literature. To convert to dBi, add 2.15 dB.
Power settings for other modes of operation can be easily extrapolated from Table 3-2. For link
budget calculations,
EIRP(Avg) dBm= Antenna Gain (dBi) + Tx Power Setting (dBm).
Though transmitter radiated power is limited in the 4.9 GHz band regardless of antenna size, the
receiver benefits from gain of larger antennas.

3.7 Installation of the MDS FOUR.9 Series
The following sections provide installation guides for:
•
SDIDUTM Installation
•
ODU Installation
3.7.1 Installing the MDS FOUR.9 Series Software Defined IDUTM
The MDS FOUR.9 Series SDIDUTM can be installed in the following three options:
1. Table top or cabinet
2. Wall mount
3. Rack mount
The MDS FOUR.9 Series SDIDUTM should be:
•
Located where you can easily connect to a power supply and any other equipment used in
your network, such as a router or PC.
•
In a relatively clean, dust-free environment that allows easy access to the rear grounding post
as well as the front panel controls and indicators. Air must be able to pass freely over the
chassis.
•
Accessible for service and troubleshooting.
•
Protected from rain and extremes of temperature (it is designed for indoor use).
3.7.1.1
Installing on a Table Top or Cabinet
The MDS FOUR.9 Series SDIDUTM can be placed on a tabletop or cabinet shelf. In order to
prevent possible disruption, it is recommended to use a strap to secure the SDIDUTM.
3.7.1.2
Installing on a Wall
An installation option for the SDIDUTM is mounting the unit to a wall. If the wall mount option is
being considered, plan to position the MDS FOUR.9 Series SDIDUTM at a height that allows
LEDs, the connectors on the front panel, and the rear grounding post to be visible at all times and
easily accessible. Also, including plastic clamps to support and arrange the ODU/ SDIDUTM
Interconnect Cable should also be considered.

Installing in a Rack
To rack-mount the SDIDUTM, use the supplied mounting brackets to secure the chassis to a 19
inch rack cabinet. As shown in Figure 3-5, the brackets can be attached to the front sides of the
enclosure. An optional 21 inch rack mount kit is also available (consult factory for details).
179H176H
Figure 3-5. MDS FOUR.9 Series SDIDUTM Dimensions
3.7.2 Installing the MDS FOUR.9 Series ODU
The MDS FOUR.9 Series ODU is intended for mounting on either a pole or antenna mast.
Each site must be assessed for the mounting method, location, and height. After defining the
mounting location and height for the MDS FOUR.9 Series ODU, re-confirm the line of sight.
When operating a 1+1 configured SDIDU™, i.e. an SDIDU™ with two power supplies and two
modem modules installed, in 1+0 mode, the ODU must be connected to the modem in the bottom
slot. If the ODU is connected to the modem in the top slot, the SDIDU™ will not communicate
with the ODU, and a link cannot be established.
3.7.2.1
Installing the Mounting Poles
First install the mounting poles, on which you will mount the MDS FOUR.9 Series ODU. It is
important to note the direction in which the ODU will point when installing the mounting pole.
The mounting pole must be mounted in a vertical position. Failure to do so may result in
improper alignment of the ODU. Vertical tilt of the ODU is accomplished from the tilt mounting
bracket.
The mounting pole must be grounded.
Now that you have installed the mounting pole, you are ready to install the MDS FOUR.9 Series
ODU onto the mounting poles. Reference Figure 3-6 through Figure 3-9.

3. Route the cable.
The SDIDUTM is equipped with TNC female connector on the front of the chassis. Depending on
the ODU type, it will be equipped with either a N-type or TNC female connector at its
interconnecting port. A length of coaxial cable (such as Times Microwave Systems LMR-400,
LMR-300 or LMR-200) fitted with the appropriate N-type or TNC male connectors is required to
connect the ODU to the SDIDUTM. This cable assembly may be supplied in fixed lengths with the
digital radio. Bulk coaxial cable of equivalent specification may also be used, with terminating
connectors applied during cable installation.
Based on an evaluation of the cable routing path, pull the ODU/SDIDUTM Interconnect cable from
one unit to the other, utilizing cable trays, ducts, or conduit as required. Take care that the ODU/
SDIDUTM Interconnect cable is not kinked or damaged in any way during installation. Be sure to
protect the TNC connectors from stress, damage and contamination during installation (do not
pull the cable by the connectors). If multiple ODU/ SDIDUTM Interconnect cables are to be
installed along the same route, the cables should all be pulled at one time. Be sure the installed
cable does not have any bends that exceed the specified cable bend radius. The ODU/ SDIDUTM
Interconnect cable should be adequately supported on horizontal runs and should be restrained
by hangers or ties on vertical runs to reduce stress on the cable. Outside the building, support
and restrain the cable as required by routing and environmental conditions (wind, ice).
The MDS FOUR.9 Series ODU/SDIDUTM and interconnection must be properly grounded in order
to protect it and the structure it is installed on from lightning damage. This requires that the ODU,
any mounting pole or mast and any exposed interconnect cable be grounded on the outside of
the structure. The SDIDUTM must be grounded to a rack or structure ground that also has direct
path to earth ground.
The ODU must be directly connected to a ground rod or equivalent earth ground. The ODU/
SDIDUTM interconnect cable should also be grounded at the ODU, where the cable enters the
structure and at intermediate points if the exposed cable run is long (typically at intervals of 100
ft), with the cable manufacturer’s grounding kits. Lightning protection devices used with the
interconnect cable must be appropriate for the transmission of the interconnect signals (DC to
350 MHz).
Provide a sufficient but not excessive length of cable at each end to allow easy connection to the
ODU and SDIDUTM without stress or tension on the cable. Excessive cable length, especially
outdoors, should be avoided to minimize signal attenuation and provide a more robust and
reliable installation. If installing using bulk coaxial cable, terminate the ODU/ SDIDUTM
Interconnect cable at each end with a TNC male connector on the SDIDUTM side and either a Ntype or TNC male connector on the ODU side that is appropriate for the cable type. Use of
connectors, tools and termination procedures specified by the cable manufacturer is
recommended.
Once the cable has been installed but before connection has been made to either unit, a simple
DC continuity test should be made to verify the integrity of the installed cable. A DC continuity
tester or digital multimeter may be used to verify a lack of DC continuity between the cable center
conductor and outer conductor, with the opposite end of the cable unconnected. With a
temporary test lead or shorting adapter connected to one end of the cable, DC continuity should
be verified between the center and outer conductors at the opposite end.

IN CASE OF DIFFICULTY...
MDS products are designed for long life and trouble-free operation. However, this equipment, as
with all electronic equipment, may have an occasional component failure. The following
information will assist you in the event that servicing becomes necessary.
TECHNICAL ASSISTANCE
Technical assistance for MDS products is available from our Technical Support Department
during business hours (8:00 A.M.–5:30 P.M. Eastern Time). When calling, please give the
complete model number of the radio, along with a description of the trouble/symptom(s) that you
are experiencing. In many cases, problems can be resolved over the telephone, without the need
for returning the unit to the factory. Please use one of the following means for product assistance:
Phone: 585 241-5510 E-Mail: mailto:TechSupport@microwavedata.com
FAX: 585 242-8369
Web: http://www.microwavedata.com/
FACTORY SERVICE
Component level repair of radio equipment is not recommended in the field. Many components
are installed using surface mount technology, which requires specialized training and equipment
for proper servicing. For this reason, the equipment should be returned to the factory for any PC
board repairs. The factory is best equipped to diagnose, repair and align your radio to its proper
operating specifications.
If return of the equipment is necessary, you will be issued a Service Request Order (SRO)
number and return shipping address. The SRO number will help expedite the repair so that the
equipment can be repaired and returned to you as quickly as possible. Please be sure to include
the SRO number on the outside of the shipping box, and on any correspondence relating to the
repair. No equipment will be accepted for repair without an SRO number.
A statement should accompany the radio describing, in detail, the trouble symptom(s), and a
description of any associated equipment normally connected to the radio. It is also important to
include the name and telephone number of a person in your organization who can be contacted if
additional information is required.
The radio must be properly packed for return to the factory. The original shipping container and
packaging materials should be used whenever possible.
When repairs have been completed, the equipment will be returned to you by the same shipping
method used to send it to the factory. Please specify if you wish to make different shipping
arrangements. To inquire about an in-process repair, you may contact our Product Services
Group at 585-241-5540 (FAX: 585-242-8400), or via e-mail at:
ProductServices@microwavedata.com
