Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. In Canada, users should be cautioned to take note that high power radars are allocated as primary users (meaning they have priority) of 5250 – 5350 MHz and 5650 – 5850 MHz and these radars could cause interference and/or damage to license-exempt local area networks (LELAN).

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the U.S. FCC Rules and with RSS-210 of Industry Canada. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with these instructions, may cause harmful interference to radio communications. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment on and off, the user is encouraged to correct the interference by one or more of the following measures:

 Increase the separation between the affected equipment and the unit;  Connect the affected equipment to a power outlet on a different circuit from that which the receiver is connected to;  Consult the dealer and/or experienced radio/TV technician for help.

Exposure Note

A Canopy module 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, the reflector dish must be installed to provide a separation distance of at least 1.5m (59.1 in) from all persons. When so installed, the module’s RF field is within 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 340mW.

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 13 cm for 2.4 GHz product and 10 cm for 5.2 and 5.7 GHz product. A power compliance margin of over 2 is artificially introduced by setting the distance to a consistent 20 cm across all modules, giving a power compliance margin of x2.4 for 2.4 GHz modules and x4 for 5.2 and 5.7 GHz modules.

In the case of the Canopy SM with reflector, the gain depends on frequency and ranges from 19 dBi (a factor of 80) for 2.4 GHz modules to 26 dBi (a factor of 400) for 5.2 GHz Extended Range and 5.7 GHz modules, so the peak power density equals the exposure limit at a distance of 10 to 80 cm. A power compliance margin is artificially introduced by defining a consistent compliance distance of 1.5 m across all modules with reflectors, giving a power compliance margin of x10 for 2.4 GHz modules, x220 for 5.2 GHz Extended Range modules, and x3.5 for 5.7 GHz modules. 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.

PRODUCT DESCRIPTION

Canopy Backhaul

Backhaul links provide point-to-point connectivity either as a standalone link or feeding an Access Point cluster as part of a Canopy network.

Backhaul modules are available in 2.4, 5.2, and 5.7 bands and in both 10 and 20 Mbps. 2.4 and

5.7 backhauls can be used with reflectors on either or both ends. Regular 5.2 backhauls cannot be used with reflectors in the US or Canada due to regulatory agency restrictions. Extended Range (ER) 5.2 Backhauls have very low transmit power and it is recommended to use reflectors at both ends.

The following table shows typical ranges for each type of backhaul.

Module Type Modulation Rate Reflectors Typical Range 5200 BH10 (DES) 5201 BH10 (AES) 5200 BH10 ER (DES) 5201 BH10 ER (AES) 5200 BH10 ER (DES) 5201 BH10 ER (AES) 5200 BH20 ER 20 One end 1 mile (1.6 km) 5200 BH20 ER 20 Both ends 5 miles (8 km) 5700 BH10 (DES) 5701 BH10 (AES) 5700 BH10 (DES) 5701 BH10 (AES) 5700 BH10 (DES) 5701 BH10 (AES) 5700 BH20 20 None 1 mile (1.6 km) 5700 BH20 20 One end 5 miles (8 km) 5700 BH20 20 Both ends 35 miles (56 km) 2400 BH10 (DES) 2401 BH10 (AES) 2400 BH10 (DES) 2401 BH10 (AES) 2400 BH10 (DES) 2401 BH10 (AES) 2400 BH20 20 None 3 miles (4.8 km) 2400 BH20 20 One end 5 miles (8 km) 2400 BH20 20 Both ends 35 miles (56 km)

2 miles (3.2 km)

When using Backhauls in standalone links, the type of Backhaul is selected based on RF environment, throughput, and range needed. When using Backhauls in a network and co-locating a BH with Access Points, the type of backhaul is usually selected based on having the BH in a different band than the APs. In other words, if the APs are 5700s, the BH could be a 5200 or a

2400. If the APs are 2400s, the BH could be a 5200 or a 5700. While distance separation of 100 vertical feet (30 m) on a tower can allow co-locating APs and BHs from the same band, choosing cross-band APs and BHs is usually the better choice.

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.

In the Canopy System, the point-to-point link is achieved utilizing backhaul modules in either the

sight issues.

In its basic form the point-to-point link is made up of a backhaul timing master and a backhaul timing slave. The cluster management module is key to the operation of the Canopy System. Backhaul timing masters must be connected to a cluster management module so that a GPS timing pulse can synchronize their transmission cycles. If one backhaul timing master module were to not be synchronized then it may be transmitting during a receive cycle of the other modules and cause de-sense. This is also true of the Canopy access point modules.

The following are some simple network diagrams of the proper way to layout single and multihopped point-to-point links.

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.

Canopy

Backhaul

Slave

• Height is essential when installing a Canopy backhaul module. The Canopy backhaul module must be mounted higher than other objects located immediately around it such as trees, buildings, tower legs, etc.

• 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. Do not place Canopy equipment in the same plane as other RF equipment.

• The means used by the installer to attach the backhaul module 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 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. 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 will be signal loss. The following illustrates a Fresnel zone.

Transmitter Receiver

• 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 point-to-point links are being planned for deployment? Each backhaul timing

master will need to utilize a cluster management module for seamless operation within the entire Canopy System.

• How will the access point clusters be deployed relative to planned point-to-point links?
