Tropos MetroMesh Routers Installation Guide, Models 6310 and 6320 iii
This device has been designed to operate with the antennas listed in Chapter 4, “Antenna Information.” Antennas not
included in the chapter or having a gain greater than 12 dBi in the 2.4 GHz band and 19 dBi in the 5.8 GHz band are
strictly prohibited for use with this device. The required antenna impedance is 50 ohms.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference, including interference that may cause undesired operation of the
device.
To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the
equivalent isotropically radiated power (EIRP) is not more than that permitted for successful communication.
RF Exposure Information
In order to meet the human RF exposure limits required by FCC and Industry Canada, the installer shall insure
separation between transmitter antennas. All persons should maintain a minimum distance from the router as specified
in the following table.
Warning
It is illegal to modify the construction of this product. Modifying the operating frequency or enhancing
the transmit output power through the use of external amplifiers or other equipment is specifically
disallowed by the “Telecommunications Act.”
Warning
This device is for outdoor or indoor use with conditions that no harmful interference to authorized radio
stations results from the operation of this device. This device shall not influence aircraft security and/or
interfere with legal communications as defined in the “Telecommunications Act.” If this device is found
to cause interference, the operator of this equipment shall cease operating this device immediately
until no interference is achieved.
5.8 GHz Point-to-Point and Point-to-Multipoint Systems
Operation of this device in point-to-multipoint systems is limited by federal regulation to
36 dBm EIRP. Unit conducted power in the 5.8 GHz band should be adjusted such that the sum of conducted power
and antenna gain does not exceed 36 dBm EIRP.
The maximum antenna gain for point-to-point operation is 19 dBi. The effective EIRP limit for point-to-point system
is 45 dBm EIRP.
