NOTICES
Federal Communications Commission (FCC) information:
This device complies with part 15 of the FCC Rules and Regulations. 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.
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. 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

•
Consult the dealer and/or experienced radio/TV technician for help.
This device must be professionally installed.
Exposure Note
The antenna of a Cyclone 900 MHz module must be installed to provide a separation distance of at least 60
cm (approx 24 inches) 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. Per Health Canada Safety Code 6, the installer of this radio equipment must
ensure that the antenna is located or pointed such that it does not emit RF field in excess of Health Canada
limits for the general population.
Currently certified 900 MHz antennas have an antenna gain of 9 dBi, which means they are limited to a
maximum RMS power of 0.4 W (26 dBm) to remain within the regulatory limit of 4 W (36 dBm) for the 900
MHz frequency band.
The applicable power density exposure limit is 6 Watt/m
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
In the case of a 900 MHz Cyclone SM or AP with an antenna gain of 9 dBi (a factor of 9) and correctly
entered in the user interface as a 9 dBi antenna, the peak power density equals the exposure limit at a
distance of 18 cm. A power compliance margin of over 11 is artificially introduced by setting the distance to
60 cm.
The compliance distance is greatly overestimated in these cases because the far-field equation neglects the
physical dimension of the antenna, which is modeled as a point-source.

Page 3: Site Selection Criteria
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 a Cyclone backhaul module. -
Page 4: Electrical Requirements
NETWORKING INFORMATION The Cyclone access point module will each utilize 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. -
Page 5: Installation Of The Equipment
INSTALLATION OF THE EQUIPMENT When power is applied to a Cyclone module or the unit reset via the web-based interface, the module will take approximately 25 seconds to boot up. During this boot up time, power on self tests and other diagnostics are being performed. The following steps are needed to install the Cyclone equipment: 1. -
Page 6: Status Page
STATUS PAGE The Status page contains information on the operation of the product. It is the default web page. The following parameters are displayed: Device Type: displays the type of Cyclone module that is currently being viewed. This field will let the operator know the frequency band of the module, the protocol that it is utilizing, and the MAC address of the module. - Page 7 Sync Input: choose the type of synchronization that this access point module will utilize. If “Sync to Received Signal” is chosen, then it is assumed that: • This access point module it connected to a Cluster Management Module and will be receiving a sync pulse via GPS •...
- Page 8 Sector ID: choose an ID number to give to this access point module. This parameter does not affect the operation of the module in any way. Its purpose is just another means to identify the access point module. When observing a subscriber module’s AP Eval Data web page, the sector ID is one of the distinguishing fields present to help the operator understand what access point module is seen.
- Page 9 Accessing Subnet: enter the network that will be allowed to access SNMP information from the Cyclone module. There are two pieces of information needed: • The network in the form of xxx.xxx.xxx.xxx • The CIDR (Classless Interdomain Routing) prefix length in the form of /xx An example would be 198.32.0.0/16 where /16 is a subnet mask of 255.255.0.0.

Page 12: Gps Status
GPS STATUS The GPS Status web page displays information about latitude, longitude, height, satellites seen and tracked when the access point module is configured to sync to received signal and is connected to a Cluster Management Module. ETHERNET STATS The Packet Stats web page reports TCP throughput and error information for the Ethernet connection of the subscriber module. -
Page 13: Expanded Stats
Late Collision: displays the total number of late collisions on the Ethernet controller. A normal collision occurs during the first 512 bits of the frame transmission. If a collision occurs after the 512 bit times, then it is considered a late collision. A late collision should be taken as a serious network problem, since it causes the frame being transmitted to be discarded. -
Page 14: Configuration Page
RSSI: displays the current value for the Radio Signal Strength Indicator. This parameter will only display information when the module is registered to an access point module and the value is only updated by either refreshing the web browser screen or configuring the Cyclone module to auto refresh (see Configuration web page.) An acceptable RSSI value for a registered link is greater than 700;... - Page 15 Default Gateway: enter in an appropriate gateway address for the module. The default value for this parameter is 169.254.0.0. Color Code: enter in a value (0-254). The color code on the subscriber module and the access point module must match in order for registration to occur. Color code is not a security feature. It is a means for the Cyclone System operator to segregate an individual network or neighbor Cyclone networks.
