Installation Preparation
Personnel
Celona recommends that installation personnel review this entire installation guide prior to beginning the
installation. Please note that installing the AP on a cell tower, building, or other structure may require at
least two people or a qualified tower crew. Installation personnel must follow standard safety precautions
concerning height, electricity, and other regulations.
Network Design Plan
Each cell site may be unique in terms of the type and number of components to install, the coverage area,
the user requirements, and so forth. Identify the structure on which the AP equipment will be installed, the
intended height where the antenna and AP will be attached, the degree of antenna down tilt, and other
necessary specifications that may impact the success of the installation. AP 21 is operating in single carrier
mode and uses ANT0 and ANT1.
Materials and Tools
The table that follows describes the materials required during the installation. The antenna elements
chosen must support the channel of operation. The total output EIRP (Equivalent Isotropic Radiated
Power) for AP21-48 is governed by Part 96 regulations of FCC and hence power is automatically
calculated and regulated by Celona software.
Item Description
Power cable < AWG16, e.g., AWG14
RF antenna cable 50-ohm feeder
RF antenna Omni or directional
Optical fiber Single mode optical fiber
Ethernet cable CAT6 rated for outdoor use
Ground cable Shorter than 330 feet (100 meters)

Data Sheet Ruggedized Access Point AP 21 - Installation Guide 6
Location and Environment
AP 21 can be installed on a pole or a wall. For the best signal coverage, place the AP 21 in an
unobstructed location. In addition to network planning, when determining where to place the AP 21, you
need to consider factors such as climate, hydrology, geology, the possibility of earthquakes, reliable
electric power, and transportation access. Avoid locating the AP 21 in areas with extreme temperatures,
harmful gases, unstable voltages, volatile vibrations, loud noises, flames, explosives, or electromagnetic
interference (e.g., large radar stations, transformer substations). Avoid areas prone to impounded water,
soaking, leakage, or condensation. The AP is certified for Class 1, Div. 2 HAZLOC installation.
Environmental Specifications
Grounding and Lightning Protection
You should protect the AP 21, antenna, and GPS against lightning. Following are guidelines
concerning grounding.
• The yellow-green ground wire must be at least 6 AWG (10 mm²) in diameter.
• Always place the grounding as near as possible to the equipment.
• Connect to a reliable outdoor grounding point (earth) using one ground screw.
• The connection of the grounding points and ground bar needs to be tight and reliable.
Rustproofing the terminals, e.g., with antioxidant coating or grease, is required.
Item Description
Operating Temperature -22°F to 131°F / -30°C to 55°C
Storage Temperature -40°F to 149°F / -40°C to 65°C
Relative Humidity (no condensation) 2% to 95% RH
Atmospheric Pressure 70 kPa to 106 kPa
Safety voltage DC: -40 VDC to -57 VDC
AC: 90 VAC to 264 VAC

Installation
Some cell site structures may have existing frameworks for attaching the
AP and antenna. For purposes of explaining the installation procedure,
this section assumes the AP will be installed on a support pole or on a wall.
Process Overview
Figure below provides an overview of the installation process.
• Installation Process Overview
• Install GPS antenna on the AP
• Install AP to the pole (or wall)
• Mount the antenna equipment
• Connect the Ethernet and ground cables
• Power on device
• Check LEDs
Weatherproofing
To protect the connection points from weather and climate, clean each
connection point before installing cold shrink tubes, per the following.
1. Insert the cable into the cold shrink tube.
2. Tighten the connector.
3. Push the cold shrink tube to the top joint and pull out the strip.
4. Ensure the cold shrink tube is tightly fitted with the connection.
Install GPS Antenna
Read the following requirements before installing the GPS antenna on
the AP.
• GPS works best when line of sight exists with the sky. Ensure no
major blockage from buildings in the vicinity. Ensure the space atop
is at least 45 degrees unblocked by any buildings.
• If possible, avoid installing the GPS antenna in the vicinity of any
other transmitting and receiving devices, to avoid interference. The
GPS antenna should be installed within 45 degrees to the lightning
rod.
• The GPS antenna system is assembled in manufacturing before
packing. The only installation step is to fix the GPS mounting bracket
on the AP 21 with the M4*14 screws, as shown in Figure below.

Installation
Install AP on Pole or Wall
Install on Pole
Ensure the pole's diameter is in the range of 1.6
in–3.9 in (40 mm–100 mm). The position of the AP
21 on the pole should be at least 47 inches (120
cm) in height.
The AP 21 mounting bracket is assembled before
packing and includes two components: the pre-
assembled bracket on the back of the device and
the pole or wall mounting bracket.
