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 2.4 or 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 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

⋅

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

sector of up to 200 subscribers.

Access Point Cluster

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

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 the 2.4, the 5.2 GHz, or the 5.7 GHz band allowing for a very versatile system architecture to reach out through the lastmile to all potential customers.

The maximum connection distances are shown in the following table:

Band Passive Reflector on SM? Maximum range

2.4 GHz No 5 miles (8 km)

2.4 GHz Yes 15 miles (24 km)

5.2 GHz Not allowed 2 miles (3.6 km)

5.7 GHz No 2 miles (3.6 km)

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.

AP_CMM2 User Manual Issue 4 Draft Page 14 of 48

• 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?
