Dbii Networks F52N-PRO User Manual

OEM Instruction Manual

F52N-PRO is a high power miniPCI card to be used in outdoor wireless systems. Please follow
the following instruction while using this card. This card is meant to be operated (and used) by
system integrators who are aware of the regulatory requirements in the area it is being used.
The following instructions need to be followed while using the card

1) Before inserting the card in a host PC board, please power down the host PC board first

2) The antenna ports (MMCX connector) should be connected to the appropriate load or
antenna before powering up the host board. Lack of Antenna (or load) while the F52N-PRO is
powered up will cause severe damage to the card

3) Please make sure any person handling the card with bare hands follows proper ESD
precautions. Improper handling could cause ESD damage.

4) The card should not be tampered or modified in any way. Tampering or modification could
cause the card to fail standard test

FCC Warning

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
the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one of the
following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment and receiver.

- Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.

- Consult the dealer or an experienced radio/TV technician for help.

The use of any antenna (based on antenna design and gain) other than those certified with the
product voids authorization of this equipment and are expressly forbidden in accordance to FCC
rules CFR47 part 15.204. The OEM and installer shall configure the output power level based
on antenna selection, gain, and installation use (i.e. point-to-point or point-to-multipoint).
Guidance of power settings and antenna selection are included in this manual for reference.
Use of the lowest usable power level for each installation is recommended. This product may
NOT be sold to the general public as professional installation is required. OEM’s must ensure
installers of end product understand the requirements and limitations of the Authorization.
Professional installation is required of equipment with connectors to ensure compliance with

health and safety issues. Below are the lists of antennas certified with this product. The OEM
must ensure that end product complies with FCC labeling requirements. This includes a clearly
visible label on the outside of the OEM enclosure specifying the appropriate identifier for this
product as well as the FCC notice below.

This device complies with Part 15 of the FCC Rules. 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.

Software Driver

Irrespective of the software driver used, this radio can only transmit in the following frequencies

2400–2483.5 MHz
5725–5850 MHz
4940-4990 MHz

Operation Frequency and Antennas

Operation in this band with antenna gains greater than 6dBi are regulated under CFR47

15.247(c)(4). Copy of regulation is included below for reference.

(1) Fixed point-to-point operation:
(i) Systems operating in the 2400–2483.5 MHz band that are used exclusively for fixed, point-to-point
operations may employ transmitting antennas with directional gain greater than 6 dBi provided the
maximum conducted output power of the intentional radiator is reduced by 1 dB for every 3 dB that
the directional gain of the antenna exceeds 6 dBi.
(ii) Systems operating in the 5725–5850 MHz band that are used exclusively for fixed, point-to-point
operations may employ transmitting antennas with directional gain greater than 6 dBi without any
corresponding reduction in transmitter conducted output power.
(iii) Fixed, point-to-point operation, as used in paragraphs (c)(1)(i) and (c)(1)(ii) of this section,
excludes the use of point-to-multipoint systems, omnidirectional applications, and multiple co-located
intentional radiators transmitting the same information. The operator of the spread spectrum or
digitally modulated intentional radiator or, if the equipment is professionally installed, the installer is
responsible for ensuring that the system is used exclusively for fixed, point-to-point operations. The
instruction manual furnished with the intentional radiator shall contain language in the installation
instructions informing the operator and the installer of this responsibility.
(2) In addition to the provisions in paragraphs (b)(1), (b)(3), (b)(4) and (c)(1)(i) of this section,
transmitters operating in the 2400–2483.5 MHz band that emit multiple directional beams,
simultaneously or sequentially, for the purpose of directing signals to individual receivers or to groups
of receivers provided the emissions comply with the following:
(i) Different information must be transmitted to each receiver.
(ii) If the transmitter employs an antenna system that emits multiple directional beams but does not do
emit multiple directional beams simultaneously, the total output power conducted to the array or
arrays that comprise the device, i.e., the sum of the power supplied to all antennas, antenna
elements, staves, etc. and summed across all carriers or frequency channels, shall not exceed the
limit specified in paragraph (b)(1) or (b)(3) of this section, as applicable. However, the total
conducted output power shall be reduced by 1 dB below the specified limits for each 3 dB that the
directional gain of the antenna/antenna array exceeds 6 dBi. The directional antenna gain shall be
computed as follows:
(A) The directional gain shall be calculated as the sum of 10 log (number of array elements or staves)
plus the directional gain of the element or stave having the highest gain.
