– Radio types and functions
– Dish sizes and configurations
– Frequency planning and network types
– Design steps for a successful deployment
Choosing the right radio style
• All Outdoor Radio – radio unit will have an integrated antenna, or
connectors. Typically mounted close to antenna or dish and fed by fiber or
Ethernet cable and PoE powered. Easy to install, typically lowers overall
installation cost. Most radios are IP based and have limited TDM capabilities.
• Split Mount Radio – Two main components, indoor unit (IDU) and
an outdoor unit (ODU). Two components are connected by using 3/8” coax
cable. IDU is typically rack mounts and the ODU can either connect directly to
the dish or be remote mounted and connected to dish using coax or flextwist
jumpers. IP and TDM capabilities increase, higher installation cost overall
compared to the all outdoor solution.
• All Indoor Radio – All radio components on the ground. Large coax
or elliptical waveguide is ran to dish. Most expensive solution to install.
However, in the event of a radio outage, no tower climbing is involved. Most
public safety networks are all indoor based.
Half Duplex/Full Duplex
Half-Duplex provides communication in both directions, but only one direction at a
time. Most unlicensed radios are half-duplex. So if the radio is listed at 200Mbps,
100Mbps is TX, 100Mbps is RX.
Full-duplex allows communication in both directions simultaneously. Licensed radios
are full-duplex.
Time Division Multiplexing
•
•
•
•
•
•
•
TDM is a method of putting multiple data streams in a single signal by separating the
signal into many segments, each having a very short duration. Example of TDM is T1 or
T3 service. When TDM ports are used on a microwave radio, bandwidth will be
subtracted from the IP bandwidth of the radio.
DS0 – 64Kbps (typical voice circuit, 24 DS0’s equal a T1 circuit)
T1 (DS1) = 1.544 Mbps (28 T1’s equal a T3)
T3 (DS3) = 45 Mbps (3 T3’s equal an OC3)
OC3 (STS3) = 155.52 Mbps (4 OC3’s equal an OC12)
OC12 = 622.08 Mbps
TDM traffic does not tolerate a high noise floor, understand your RF environment
before deploying.
Ethernet/IP
•
•
•
Ethernet is the most popular and considered the network topology standard for
most computer and VoiP connections. Connections are made at 10/100Mbps or
1/10Gbps. Cable lengths limited to 325ft between active devices.
IP is a network layer protocol for addressing and routing packets of data between
host on a TCP/IP network. IP is a connectionless protocol that provides best effort
delivery.
Most important part when designing an Ethernet backhaul is understanding the
customers bandwidth needs.

11GHz – 2ft Class B, 3ft Class A Dish / 40MHz Channel

The Equation for a successful radio reception:
TX power + TX antenna gain – Path loss – Cabling loss + RX
antenna gain – 10dB fade margin > RX Radio sensitivity or
(less commonly) RF noise floor

Antenna Polarization
Point-to-Point (backhaul) systems may use either vertical or horizontal polarization
as long the same polarization is used at each end. Horizontal polarization may
perform slightly better when transmitting through a forested area, otherwise there
is very little difference in propagation effects.
How Far Will It Go?
6 GHz (10-40+ miles)
11 GHz (5-20 miles)
18/23 GHz (1-5 miles)
Frequency Planning
• The objective of frequency planning is to assign
frequencies to a network using as few frequencies as
possible and in a manner such that the quality and
availability of the radio link path is minimally affected by
interference. The following aspects are the basic
considerations involved in the assignment of radio
frequencies
Chain Configuration w/ Frequency Planning
All sites reside on a single path. This is a very sensitive
topology in which the first link malfunction can cause a
complete network failure.

Star Configuration w/ Frequency Planning
Star Topologies use a separate link from a hub to each site. This is very simple,
but inefficient for microwave systems, as it requires possible longer paths and
LOS for each link. The star topology also makes for poor frequency reuse since all
links originate at the same point.

Ring Configuration w/ Frequency Planning
• The ring topology provides superior network availability, due
to the rings inherent path diversity. In a ring topology, service
failures occur when two or more links malfunction.

Understanding the Basics
• Free Space Loss (FSL) – is the expected attenuation of a signal as it travels
away from a transmitting device. As the path distance increase, the power
density decreases.
• Fade Margin – the difference between the unfaded receive signal level and
the receiver sensitivity threshold. Every link must have sufficient Fade Margin
to protect against path fading that weakens the radio signal.
• Link Availability – Fade margin is directly related to link availability, which is
the percentage of time that the link is functional. The percentage of time that
the link is available increases as the fade margin increases. Bottom line, design
your link as far away from the radio’s receiver threshold as possible.
• Path Fading – path fading occurs more frequently in flat, humid environments
than in rough, dry locations. Therefore, a link in a flat humid area requires a
greater fade margin to achieve the same level of link availability as a link in a
rocky and dry location.
Understanding Your Rain Region
Rain Region Map:
The energy of microwave signals is absorbed by rain: rain can cause an
outage if enough energy is absorbed so that the receiver loses the signal

Climate Factor
Climate Conditions and Path Fading
Path fading occurs more frequently in flat, humid environments than in rough,
dry locations. Therefore, a link in flat and humid areas requires a greater Fade
Margin to achieve the same level of link availability as a link in a rocky and dry
location. When calculating link performance the climate factor must be taken
in consideration

Importance of a Site Survey
•
•
•
•
•
What is your customers budget?
What throughput does customer need?
Do you have line-of-sight for your path?
How are you mounting radios or dishes?
What is your cable path from radio to network
head end?
• Look for good grounding sources.
• Don’t forget lightning protection.
Importance of Spectrum Analysis
• Spectrum analysis is a must for unlicensed spectrum
(900MHz, 2.4, 5.3, 5.4, 5.8GHz).
• Spectrum analysis should be considered for 4.9GHz and
3.65GHz spectrum.
• Spectrum analysis should be performed at height of antennas
and dishes.
• Document the noise floor and look for open channels.
• Never assume that just because it’s rural that there is no noise
floor, if towers are in the area, there is noise.
• Consider making an investment or renting a good spectrum
analyzer
Rules to Remember
• As frequency rises, available bandwidth typically rises, but distance and
ability to overcome obstacles is reduced.
• The more sensitive the radio, the lower the power signal it can
successfully receive, stretching right down to the noise floor. As radio
modulation increases, receiver sensitivity decreases.
• Know your noise floor, do a spectrum scan, survey your area to see what
else is hanging in the air.
• Establish a fade margin of no less than 10dB in good weather conditions,
this will provide a high degree of assurance that the system will continue
to perform effectively in a variety of weather or interference.
• Avoid obstructions in your path whenever possible and understand the
distance between you link.
• Avoid force fitting a solution, hoping it will work.
• Never go “cheap” on your cable
• Understand your application and choose accordingly
