Powering the Access Point
The Celona AP 20 can be powered by IEEE 802.11bt (POE++) on the WAN Ethernet port or
connected to an AC electrical outlet using the optional AC power injector/adapter.
Access Point Discovery and Provisioning
The AP will connect to the Celona Orchestrator for provisioning and discover the Celona Edge
within the network on-premises or in the private/public cloud based on the site assignment.
The AP will then connect directly to the Celona Edge and establish control and data plane
connections. Once this is completed, the 5G LED on the AP will turn blue, signifying the private
5G network is operational. This will take approximately 2-3 minutes.
Configuring the Access Point
The Celona AP 20 supports zero-touch provisioning. The AP is preconfigured with details
necessary to discover the Celona Orchestrator and the Celona Edge automatically. After the
AP 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 20. Once the AP has gone operational, it is able
to provide services to mobile stations. The mobile stations can interact with the enterprise
network via the Celona Edge. The user data and control signals are encrypted. The Celona AP
20 performance is periodically monitored by the Celona Edge and operational parameters are
continually optimized if necessary. Refer to the Celona Orchestrator configuration guide for
detailed instructions on configuring Celona access points.

Solution Architecture
The high-level architecture that enables the Celona AP 20 is shown below.
The system consists of the essential functions detailed in Figure 1: System
Architecture. 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 20 to the serving Celona Edge.
Each Celona AP 20 obtains service via its serving Celona Edge. The Celona Edge
registers the Celona AP 20, arbitrates spectrum with a FCC approved Spectrum
Access Service (SAS) system in the United States and algorithmically determines
the most optimal radio parameters for the AP.
The Celona Edge becomes automatically aware of the Celona AP 20’s location and
its existing surrounding radio environment. Once the AP is admitted by the Celona
Edge, the AP can commence radio transmissions and service the mobile stations.
Celona AP 20 capabilities
The following sections give the reader the capabilities of the Celona Indoor Access
Point (AP), which is based on the Qualcomm platform. The AP hosts functions to
provide the following services:
• Resource management with admission and flow control
• Encryption of user data and control streams
• Registering mobile stations with Celona Edge for connectivity services
• Paging the mobile stations that are in power save mode
• Fairness in allocation of resources across multiple stations in uplink & downlink
directions
• Measurement configurations and handling of mobility of mobile stations

Operations and Maintenance
The Celona AP 20 is operationally maintained by the Celona Orchestrator and
Celona Edge using NETCONF. Celona AP 20’s radio parameter provisioning,
performance monitoring and fault monitoring occur over the NETCONF interface.
Celona AP 20’s performance is monitored between every 5 minutes and 15 minutes
based on the periodicity determined by the Celona Edge. If a fault surfaces on the
AP, the fault is automatically propagated by the AP to the Celona Edge and the
Celona Orchestrator.
Security
The certificates that are required to establish HTTPS connections with the Celona
Orchestrator and the IPSEC channel with the Celona Edge are installed to the
Indoor AP at the factory. If the certificates 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 at the Celona AP 20 through the Celona Orchestrator. IKEv2 is used
to establish the IPSEC tunnel between the Celona AP 20 and the Celona Edge.
Phase and time synchronization
Celona AP 20 supports Time Division Duplex (TDD) which has strict requirements
for maintaining time and phase synchronization so that it does not interfere with
neighboring APs. The Celona AP 20s 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. If the AP cannot obtain a GPS lock for any reason, Celona
AP 20 synchronizes with a Precision Time Protocol (PTP) server to maintain time,
phase, and frequency synchronization.
Data and voice connectivity
Mobile stations can access data, video, and voice applications over the enterprise
IP network via the Celona Edge after the Celona AP 20 has its radio enabled. Note
that the Celona AP 20 can provide voice, video, and data sessions simultaneously
to mobile stations. Celona AP 20 automatically determines the capability of mobile
stations before determining whether requested services can be accommodated.
Celona AP 20 and Celona Edge perform admission control for mobile stations
and Celona Edge enforces authentication of the mobile station before accepting
service requests and keep all control signals and user data encrypted.
Celona AP 20 employs sophisticated adaptive modulation and code rate control
for adapting mobile station link according to the dynamic channel conditions
seen on the air interface. It also employs eective power control to keep transmit
powers from the mobile stations as low as practicable.
Power save mode
Celona AP 20 enables, and controls power save options on the mobile stations.
When a mobile station has encountered a long lull in data volume, Celona AP 20
monitors trac volume on each flow enabled at the mobile station.
When the trac volume is zero for a duration of time, duration determined by the
Celona AP 20 based on mobile capability as well as current loading in the system,
Celona AP 20 enables Power Save mode on the mobile station. While in power
save mode, the mobile station can turn o its receiver and transmitter functions
for the most part except for essential functions. This increases the battery standby
time on the mobile stations.
When the mobile station is in power save mode and if there is user data destined
towards the mobile station, Celona Edge pages the mobile station indicating data
arrival via the Celona AP 20 in order to awaken the station.

Radio access technology
Celona AP 20 implements an extensive set of 3GPP worldwide standards to provide
advanced, 5th-generation packet radio service to mobile stations.
Supported frequency band
The Celona AP 20 is a 3GPP Release 15 compliant integrated 5G NR with external
antenna support, operating within the 3550-3700 MHz spectrum band. AP 20
supports 2x2 MIMO (multiple-input, multiple-output), up to 256-QAM modulation
and can be ceiling or wall mounted. Any Celona AP 20 within a Celona private 5G
network is automatically assigned frequency and power levels by Celona’s unique
Self Organizing Network (SON) software function, after the Celona Edge retrieves
available frequency channels per AP from SAS, given each AP’s geo-location.
Frequency Band Support (SKUs)
AP20-48 3.55-3.7 GHz
Seamless session mobility
If there are multiple Celona AP 20s in the system all connecting to the same Celona
Edge, the Celona AP 20 s can enable seamless mobility for mobile stations. The
source and target Celona AP 20s handle the transfer of contextual information
corresponding to existing flows setup for the mobile station automatically.
Coverage area
The coverage area of each Celona AP 20 depends on several factors:
• Transmit power authorized by the Spectrum Manager
• Transmit power set on the Celona AP 20 by Celona Edge
• Number of other APs operating on the same frequency in the geographic area
• Proximity of other APs operating on a dierent frequency but in the same band
• Building type and material types used within the building
• Expected minimum for data rate at the edge of coverage
As a rule of thumb, at maximum transmit power, the Celona AP 20 should provide
coverage between 10,000 and 25,000 square feet.
Transmit power
The Celona AP 20 can transmit at a maximum power of 24 dBm max per port, plus
a built-in omni with max 6 dBi antenna gain.
Supported system bandwidth
The Celona AP 20 supports one sector, and the system bandwidths are supported
are 20/40 MHz
