Exposure Note
The Canopy Subscriber Module (SM) must be installed to provide a separation distance of at least
20 cm (7.9 in) from all persons, when adding the Canopy reflector dish (in the 5.7 GHz band), the
reflector dish must be installed to provide a separation distance of at least 1.5m (59.1 in) from all
persons and does not emit a RF field in excess of Health Canada limits for the general population;
consult Safety Code 6, obtainable from Health Canada’s website http://www.hc-sc.gc.ca/rpb.
In both configurations the maximum RMS power does not exceed 200mW.
The applicable power density exposure limit is 10 Watt/m
2
, according to the FCC OET Bulletin 65,
the ICNIRP guidelines, and the Health Canada Safety Code 6. The corresponding compliance
distances referenced above have been determined by assuming worst-case scenarios. The peak
power density (
S
) in the far-field of a radio-frequency source with rms transmit power
P
and
antenna gain
G
at a distance
d
is
2
4 d
GP
S
π
=
In the case of the Canopy SM
without
reflector, the gain is 8 dBi (a factor of 6.3), so the peak
power density equals the exposure limit at a distance of 10 cm. A four-fold additional compliance
margin is artificially introduced by doubling the distance to 20 cm.
In the case of the Canopy SM
with
reflector, the gain is 26 dBi (a factor of 400), so the peak power
density equals the exposure limit at a distance of about 80 cm. An almost four-fold additional
compliance margin is artificially introduced by defining the compliance distance of 1.5 m. The
compliance distance is greatly overestimated in this case because the far-field equation neglects
the physical dimension of the antenna, which is modeled as a point-source.

BACKGROUND INFORMATION ON NETWORKING
Computers are assigned IP addresses by network operators, which have two methods available,
static or dynamic IP addressing. The user of this document will need to understand how IP
addressing is done at their particular location.
All Canopy radio products (Subscriber Modules, Access Point Modules, and Backhaul Modules)
have the default IP address of 169.254.1.1. For a computer to talk to Canopy, as it comes from the
factory, either of the following conditions must be met:
If the computer is not configured for DHCP, then it has to have a static IP address on
the 169.254 network (i.e. 169.254.1.5)
If the computer is configured for DHCP, then it will automatically obtain an IP address
on the 169.254 network after minute or two as long as it is not connected to the
network.

SYSTEM OVERVIEW AND SITE PLANNING
Definitions:
Access Point Module
– one (1) module that is used to distribute Internet services in a 60-degree
sector of up to 200 subscribers.
Access Point Cluster
– two (2) to six (6) Access Point modules used to distribute Internet service to
a community of up to 1200 subscribers. Each Access Point module will cover a 60-degree sector
for a total of up to 360 degrees.
Cluster Management Module
– a module that contains power, GPS timing, and networking for an
Access Point cluster. Canopy Backhaul Modules can also be connected to the Cluster
Management Module making it the central connectivity point for an entire site.
Overview:
In the Canopy System, each subscriber module communicates with an Access Point module in an
assign time slot that is controlled by the Access Point. The Access Point module coordinates the
data needs of the subscriber in both the downlink and the uplink to allow for seamless
communication throughout the entire network.
Access Point modules use a multipoint protocol to communication with each of the subscriber
modules registered in the system. Access Point modules can be deployed in either the 5.2 GHz
band or the 5.7 GHz band allowing for a very versatile system architecture to reach out through the
last-mile to all potential customers.
In the 5.2 GHz band, subscriber module may be as far as 2 miles away from the Access Point
module. In the 5.7 GHz band, subscriber module may be as far as 10 miles away from the Access
Point module when utilizing a Canopy passive reflector kit on the subscriber.
Note: Distances may
vary based on terrain and other line of sight issues.
To bring a network feed out to a remotely located Access Point cluster the Canopy Backhaul
Module can be used to create a point-to-point link out to the location. The Canopy Backhaul
Module will interface with the Cluster Management Module to seamlessly integrate the entire
system. For more information on the
Canopy Backhaul Module
see its user manual.
The Cluster Management Module is key to the operation of the Canopy System. At one cluster site
or throughout the system the Cluster Management Module provides a GPS timing pulse to each
module so that their transmission cycles are synchronized. If one Access Point module were to not
be synchronized then it may be transmitting during a receive cycle of the other modules and cause
the receiver to be desensitized. This is also true of the Canopy Backhaul timing master Modules.

SITE SELECTION CRITERIA
There are various issues that need to be taken into consideration when choosing a location for
the network infrastructure. The following is a list of those considerations. There may be others,
as each site is unique.
Height is essential when installing Canopy Access Points. The Canopy Access Point
modules must be mounted higher than other objects located immediately around them
such as trees, buildings, and tower legs, but at least 2 feet (0.6 m) below the highest
point on the tower or pole for lightning protection.
There should be no obstructions that will interfere with the unit’s internal antenna. The
area immediately in front of an Access Point module must be clear of all obstructions.
Will the installation area change in the future? Will there be structures high enough to
interfere with the signal? Will trees grow into the line-of-sight path?
When possible, avoid high RF energy sites (i.e. AM/FM stations, high powered
antennas, etc.) Do not place Canopy equipment in the same plane as other RF
equipment.
The means used by the installer to attach the Access Point cluster to the tower,
rooftop, or pole should be rigid and should not move or flex due to wind or other
vibrations.
Tower availability…will a tower have to be erected?

There must be grounding systems available for protection of the Canopy equipment.
Lighting arrestors are required in installation area to transport lightning strikes away
from equipment.
GENERAL CONSIDERATIONS
Fresnel Loss - The Fresnel Zone is a theoretical area around the line of sight of an antenna
transmission that can affect the signal strength. Objects that penetrate the Fresnel Zone can
cause fading of the transmitted signal. This fading is caused by the cancellation of the signal due
to out-of-phase reflections and absorption of the signal. An unobstructed line of sight is important,
but it is not the only determination of an adequate placement. Even though the path has a clear
line of sight, if obstructions (such as terrain, vegetation, metal roofs, cars, etc.) penetrate the
Fresnel zone, there may be signal loss. The following illustrates a Fresnel zone.

Free Space Path Loss – As an RF signal travels through space, it is attenuated by the distance
from the initial transmission point. The farther away from the transmission point, the weaker the RF
signal.
Foliage Loss – Tree and plant foliage will cause additional signal loss. Seasonal density, moisture
content of the foliage, and other factors such as wind may change the amount of loss. Caution
should be used when a link may transmit though this type of environment.
Carrier to Interference – describes how much signal advantage must be engineered into the radio
link to tolerate an interfering transmission.
How many Access Point clusters are being planned for deployment? Each cluster will need to
use a Cluster Management Module for seamless operation within the entire Canopy System.
How many Access Point modules are being planned for each site in the deployment? Access
Point modules can be distributed; they do not necessarily have to be mounted immediately next to
each other for operation. For example, if the site is a three-legged tower, two Access Point
modules can be mounted to each of the tower legs.
How will the subscriber modules be deployed relative to planned Access Point clusters?

CHANNEL PLANS
Whether using Hz or 5.7 GHz modules, frequencies should never be placed closer than
20 MHz. The Canopy modules allow the operator to chose frequencies every 5 MHz.
This is so that in the event of co-location with other equipment the operator can
customize the channel layout for interoperability.
5.2 GHz Recommended Frequencies
The following are the 3 non-overlapping channels that are recommended by the Canopy team for
use with an Access Point cluster:
5.275 GHz
5.300 GHz
5.325 GHz
5.7 GHz Recommended Frequencies
The following are the 4 non-overlapping channels that are recommended by the Canopy team for
use with an Access Point cluster
Note: only 3 channels are actually needed for the fully populated
cluster. The four channels are also used for backhaul point-to-point links
:
5.745 GHz
5.765 GHz
5.785 GHz
5.805 GHz
Single Access Point Module
A single Access Point module can use any of the frequency channels that are available.
Single Access Point Cluster
Use the following table as a recommendation to assign frequency channels and sector IDs (see
section on Configuration interface screen for information on sector IDs). Each frequency is
reused on the sector that is at a 180-degree offset. Symbol refers to the layout in the diagram
below (Figure 6).

NETWORKING INFORMATION
The Canopy Access Point module will each use an IP address on the operator’s network. It is
recommended that the Access Point modules
never
be placed directly onto the Internet. IP
addresses may be assigned sequentially clockwise around an Access Point cluster for easier
manageability. The operator will also need to identify the appropriate subnet mask and network
gateway each of the modules.
From the factory, each Access Point module is assigned a unique MAC address and the following
default networking information:
IP address of 169.254.1.1
Subnet mask of 255.255.0.0
Network gateway of 169.254.0.0
LIGHTNING PROTECTION
The Canopy Access Point module, Cluster Management Module, and GPS antenna must
be mounted at least 2 feet below the highest point at the site for lightning strike mitigation.
It is highly recommended that the site have a lightning protection system installed.
Ensure the location is properly grounded for lightning protection according to all applicable
national and local codes.
To protect operator equipment from surges on the Ethernet cable that is connected to the
Canopy System, the Canopy surge suppressor must be used.
ELECTRICAL REQUIREMENTS
Specifications for the voltages and distance can be found in the
Specification
section of
this manual.
There is a fuse in the CMM for short-circuit protection. In addition, good electrical practice
requires a circuit breaker in the electrical circuit supplying the CMM, or other means to
provide a disconnect device and back-up short-circuit protection.
Make certain the installation conforms to applicable country and local codes, such as the .
National Electrical Code (NEC) in the US. If uncertain of code requirements, obtain the
services of a licensed electrician.
