Installation
Connect Power Connector
Since the length of cable needed for power varies from site to site,
the two ends of the power adaptor are bare terminal ends. The
installer would need to make the power cable according to the
actual measurements of the installation site and assemble the power
plug and power terminal on the two ends of the power adaptor.
Strip 0.47in/12mm of the insulating layer with a wire stripper which is
then used for connecting to the connector. The power cord length is
ideally kept below 330 ft/100m.
The connection steps for the power cable are as follows.
• Assemble the power plug. The power plug will be installed on the
end of the input direction. Refer to the labels on the power plug
for connecting the live wire and ground wire to the corresponding
terminals separately and tighten the screws. Assemble the power
terminal. The power terminal will be installed on the end of the
output direction. Refer to the figure below to connect the live wire
and neutral wire.
• Connect the power cable to the PWR interface in the wiring cavity.
• The power cable lays along the lint slot and stretches out the
wiring cavity from the PWR port.
• The input of the power adaptor connects to the outlet. If the outlet
is outdoors, place the power adaptor Outdoors. If the outlet is
outdoors, place the power adaptor in a waterproof box.
• After the cable connection is complete in the wiring cavity, tighten
the screws on the cover to close the wiring cavity using an M4
cross screwdriver.

Data Sheet Ruggedized Access Point AP 21 - Installation Guide 13
Install Antenna Feeder System
There are two kinds of outdoor antennas, omni-directional and directional.
• Adhere to the following guidelines when installing an omni-directional antenna. The
diameter of the pole should be 1.4in/35mm to 2in/50mm. A typical case is to use the
50mm-diameter round-steel-made pole (with details depending on the specific
antenna type). Make sure that the top of pole and the clamp beneath the antenna
are at the same level after installing the omni-directional antenna on the pole.
Make sure the antenna is high enough to meet the coverage requirements, and that
the antenna top falls within the 45 degrees safety angle towards an independent
lightning rod. Refer to Figure: Omni antenna installation.
• In case it is impossible to install an independent lightning rod due to environmental
limitations, the installation method shown in Figure: Alternative omni antenna
installation can be used. Be aware that the pole supporting the lightning rod should
be kept at least 1m away from the omnidirectional outdoor antennas.
Connect Ground Cable
Prepare the grounding cable according to the actual
measurements and requirements of the specific installation
site. The AP 21 has two grounding screws located on the
bottom of the unit as shown below.
Unscrew one grounding screw, connect one end of the
ground cable to the grounding screw, and fasten it again.
The other end of the ground cable needs to connect to a
good grounding point.

Data Sheet Ruggedized Access Point AP 21 - Installation Guide 16
The high-level architecture that enables the Celona AP 21 is shown below.
The system consists of the essential functions for a private 5G NR network.
The Celona Orchestrator performs AP authentication, validates the AP’s
serial number, determines the network the AP needs to connect to and
finally directs the Celona AP 21 to the serving Celona Edge.
Each Celona AP 21 obtains service via its serving Celona Edge. The
Celona Edge registers the Celona AP 21, arbitrates spectrum with an FCC
approved Spectrum manager and algorithmically determines the most
optimal radio parameters for the AP.
The Celona Edge is aware of the Celona AP 21’s location and its existing
surrounding radio environment automatically. Once the AP is admitted by
the Celona Edge, the AP can commence radio transmissions and service
the mobile stations.
System architecture
Celona AP 21 capabilities
The following sections give the reader the capabilities of the Celona AP 21. The AP is a
5G NR small cell.
The AP hosts functions to provide the following services:
• Resource management: Admission control, Flow control
• Encryption of user data and control streams
• Registering mobile stations with Celona Edge for Voice and Data services
• Data only or Voice only or Data + Voice service
• Paging the mobile stations that are in power save mode
• Fairness in allocation of resources across multiple mobile stations in both uplink and
downlink directions
• Measurement configurations and handling of mobility of mobile stations
Discovery
The Celona AP 21 supports zero-touch provisioning. The AP is preconfigured
with details necessary to discover the Celona Orchestrator and the Celona Edge
automatically. After the DP (Domain Proxy) discovers the Celona Orchestrator and the
Celona Edge, the AP gets provisioned with operational parameters and is authorized
to transmit.
The Celona Edge alone controls the radio frequency transmission of the Celona AP
21. Once the AP is operational, it can provide services to mobile stations. The mobile
stations can connect with the Packet data network as well with Voice and multimedia
networks via the Celona Edge.
The user data and control signals are encrypted. The Celona AP 21’s performance
is periodically monitored by the Celona Edge and operational parameters are
continually optimized.

Data Sheet Ruggedized Access Point AP 21 - Installation Guide 17
Phase and time synchronization
Celona AP 21 is a “Time division duplex (TDD)” 5G NR small cell. TDD small cells have strict
requirements for maintaining time and phase synchronization so that they do not interfere with
neighboring APs.
The Celona AP 21s have a built-in, high-fidelity GPS chip that can establish location as well as
maintain clock synchronization. The AP’s carrier frequency accuracy, time and phase drifts are
disciplined by the onboard GPS clock.
Data and voice connectivity
As seen in the figure below, mobile stations can obtain data and/or voice connectivity via the
Celona Edge after the Celona AP 21 has its radio enabled. Celona AP 21 automatically determines
the capability of mobile stations before determining whether requested services can be
accommodated.
Celona AP 21 and Celona Edge perform admission control for the mobile station and Celona
Edge enforces authentication of the mobile station before accepting service requests. Further,
Celona Edge and Celona AP 21 encrypt all control signals and user data between the mobile
station and the Celona Edge.
Celona AP 21 employs sophisticated adaptive modulation & code rate control for adapting
mobile stations’ link according to the dynamic channel conditions seen on the air interface
between the mobile stations and Celona AP 21. Celona AP 21 also employs eective power
control to keep transmit powers from the mobile stations as low as practicable.
Operations and Maintenance
The Celona AP 21 is operationally maintained by the Celona
Orchestrator and Celona Edge using NETCONF.
Celona AP 21’s radio parameter provisioning, performance
monitoring and fault monitoring occur over the NETCONF
interface. The AP supports the following technical reports from
the Broadband Forum
Fault management TR-157 Amendment 5
Celona AP 21’s performance is monitored between every 5
minutes and 15 minutes, determined by the Celona Edge. Any
AP faults are automatically propagated by the AP to the Celona
Edge and Celona Orchestrator.
Security
The Celona AP 21’s interfaces are secured by IPSEC or SSL.
The certificates required to establish HTTPs connections with
the Celona Orchestrator and IPSEC with the Celona Edge are
provisioned at the factory.
If the certificates on the Celona AP 21 need to be updated or
replaced, the process is automatically triggered and managed
by the Celona Edge. The certificates conform to the industry
compliant X.509 standard.
The IPSEC gateway is provisioned within the Celona AP 21
through the Celona Orchestrator. IKEv2 is used to establish the
IPSEC tunnel between the Celona AP 21 and Celona Edge.

Power save mode
Celona AP 21 monitors trac volume and enables power save options when a
mobile station has encountered a long lull in data volume, such as when a voice or
video call is terminated.
While in power save mode,
• the mobile station can minimize its receiver and transmitter functions to
essential functions, increasing the battery standby time.
• the Celona Edge will awaken the mobile station during user data transmission.
