XH2-240 Hardened Access Points
23
RF Exposure
Generic Information
The Riverbed Access Point products are designed to comply with the following national and
international standards on Human Exposure to Radio Frequencies:
US 47 Code of Federal Regulations Part 2 Subpart J
American National Standards Institute (ANSI) / Institute of Electrical and Electronic
Engineers / IEEE C 95.1 (99)
International Commission on Non Ionizing Radiation Protection (ICNIRP) 98
Ministry of Health (Canada) Safety Code 6. Limits on Human Exposure to Radio Frequency
Fields in the range from 3kHz to 300 GHz
Australia Radiation Protection Standard
To ensure compliance with various national and international Electromagnetic Field (EMF)
standards, the system should only be operated with Riverbed approved antennas and
accessories.
Declaration on Conformity
This access point product has been found to be compliant to the requirements set forth in CFR
47 Section 1.1307 addressing RF Exposure from radio frequency devices as defined in
Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency
Electromagnetic Fields.
Use is permitted with antennas having an effective maximum gain of 9 dBi in the 2.4 GHz band
and 6 dBi in the 5 GHz band. Antennas having a gain greater than this are strictly prohibited for
use with this device. The required antenna impedance is 50 ohms. Effective maximum gain is
antenna gain minus cable loss. A minimum separation distance of 31 cm between the antenna
and all persons is required during normal operation.
Only antennas recommended by Riverbed for use with the product should be installed. The use
of any other antennas may cause damage to the access points or violate regulatory emission
limits and will not be supported by Riverbed.
International Guidelines for Exposure to Radio Waves
The Riverbed Access Points include radio transmitters and receivers. It is designed not to
exceed the limits for exposure to radio waves (radio frequency electromagnetic fields)
recommended by international guidelines. The guidelines were developed by an independent
scientific organization (ICNIRP) and include a substantial safety margin designed to ensure the
safety of all persons, regardless of age and health.
As such the systems are designed to be operated as to avoid contact with the antennas by the
end user. It is recommended to set the system in a location where the antennas can remain at
