Radio Frequency Interference Requirements
This device complies with Part 15 of FCC Rules.
Operation is subject to the following conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may cause
undesired operation.
3. This device should not be co-located or operating in conjunction with any other antenna or
transmitter.
Interference Statement
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.
FCC Caution: To assure continued compliance, (example –use only shielded interface cables when
connecting to computer or peripheral devices). Any changes or modifications not expressly approved by
the party responsible for compliance could void the user’s authority to operate this equipment.
Warning
The user is advised to keep apart from the base-station and antenna with at least 45cm when the
base-station is in operation.
Please install a lightning arrestor to protect the base station for lightning dissipation during rainstorms.
Lightning arrestors are mounted outside the structure and must be grounded by means of a ground wire to
the nearest ground rod or item that is grounded.
A8n product series require professional installation. The installer shall be responsible for ensuring that
the proper 5GHz antenna is employed so that the limits in FCC Part 15.247 are not exceeded. The
installer is responsible for ensuring that the 5GHz radio is used exclusively for fixed, point-to-point
operations.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a
type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential r
adio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotr
opically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
Conformément àla réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec un
e antenne d'un type et d'un gain maximal (ou inférieur) approuvépour l'émetteur par Industrie Canada. D

ans le but de réduire les risques de brouillage radioélectrique àl'intention des autres utilisateurs, il faut ch
oisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dép
asse pas l'intensiténécessaire àl'établissement d'une communication satisfaisante.
This radio transmitter (identify the device by certification number, or model number if Category II) has b
een approved by Industry Canada to operate with the antenna types listed below with the maximum perm
issible gain and required antenna impedance for each antenna type indicated. Antenna types not included
in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for
use with this device.
Le présent émetteur radio (identifier le dispositif par son numéro de certification ou son numéro de modèl
e s'il fait partie du matériel de catégorie I) a étéapprouvépar Industrie Canada pour fonctionner avec les t
ypes d'antenne énumérés ci-dessous et ayant un gain admissible maximal et l'impédance requise pour cha
que type d'antenne. Les types d'antenne non inclus dans cette liste, ou dont le gain est supérieur au gain m
aximal indiqué, sont strictement interdits pour l'exploitation de l'émetteur.
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the f
ollowing two conditions: (1) this device may not cause interference, and (2) this device must accept any i
nterference, including interference that may cause undesired operation of the device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de
licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de
brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le br
ouillage est susceptible d'en compromettre le fonctionnement.

1Introduction
This guide is designed to provide the information needed to mount A8n Series Base Station
(BTS) at the site location. A8n series contains 3 variants:
i) A8n: contains A8n base station plus 4 external 2.4GHz 14dBi panel antennas. Each
panel antenna can adjust direction and tilt.
ii) A8Ein: integrated base station, multi-beam 2.4GHz 19dBi antenna array for 80 degree
sector coverage.
iii) A8in: integrated base station, 14dBi antennas and RF cabling optimized for long range
360-degree access coverage.
It is assumed in this document that a site survey has been performed before the site installation.
The appropriate antenna pole and BTS locations have been selected. It is a good practice to have
a document consists of a map and drawing illustrating the base station and poles locations,
antenna bearing/down-tilt, antenna height, etc… A planning on IP network is also an important
issue for network planning.

4Mounting A8n 2.4GHz antenna and cable connection
Introduction
1. The A8n AP has 4 external 2.4GHz panel antennas. The A8Ein and A8in has internal
2.4GHz antenna. External 2.4GHz panel antenna gives you more freedom to adjust the
direction and tilting of each antenna. Internal 2.4GHz antenna is easier for installation.
2. At the top of A8n, there are 8 N-female RF connector marked with 1-8. They are
grouped to 4 groups to connect to 4 external 2.4GHz panel antenna.
3. It is recommended to seal the A8n series RF ports with weatherproof materials to prevent
water leakage.

4.1 Mounting of A8n 2.4GHz Panel antenna
1. Mount the 2.4GHz radio antenna to the pole. It is recommended that to install the
standard A8n 2.4GHz antenna with the RF ports facing downward, as shown in Figure
17.
2. Adjust the direction and down-tilt angle of the A8n 2.4GHz antenna to align, as shown in
Figure 18.

4.2 Cable connection from A8n to 2.4GHz panel antenna
1. Connect RF cable from panel antenna port to A8n 2.4GHz RF port at the top of A8n.
2. RF port 1 and 2 of A8n must connect to the same panel antenna. The same for ports
(3.4), (5,6) and (7.8) which each pairs must connect to the same panel antenna. It is
recommended to connect the A8n port to antenna port according Figure 20 mapping.
3. It is recommended to seal the A8n series 2.4GHz antenna RF ports with weatherproof
materials to get the best performance according to the procedure in chapter 6 of this
document.
