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 22 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 22. 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 22 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. 07 ## Solution architecture The high-level architecture that enables the Celona AP 22 is shown below. 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 22 to the serving Celona Edge. Each Celona AP 22 obtains service via its serving Celona Edge. The Celona Edge registers the Celona AP 22, arbitrates spectrum with a FCC approved Spectrum Access Service (SAS) system in the United States (AP22-48 only) and algorithmically determines the most optimal radio parameters for the AP. The Celona Edge becomes automatically aware of the Celona AP 22’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. ![AP 22 solution architecture](https://celona.io/volumes/images/Resources/Installation-Guides/_255x255_fit_center-center_70_none_ffffff/62557/ap22-architecture.webp) ### Celona AP 22 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 08 ## Operations and maintenance The Celona AP 22 is operationally maintained by the Celona Orchestrator and Celona Edge using NETCONF. Celona AP 22’s radio parameter provisioning, performance monitoring and fault monitoring occur over the NETCONF interface. The AP supports technical reports from the Broadband Forum. Celona AP 22’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 22 through the Celona Orchestrator. IKEv2 is used to establish the IPSEC tunnel between the Celona AP 22 and the Celona Edge. ### Phase and time synchronization Celona AP 22 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 22s 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 22 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 22 has its radio enabled. Note that the Celona AP 22 can simultaneously provide voice, video, and data sessions to mobile stations. Celona AP 22 automatically determines the capability of mobile stations before determining whether requested services can be accommodated. Celona AP 22 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 22 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 effective power control to keep transmit powers from the mobile stations as low as practicable. ### Power save mode Celona AP 22 enables, and controls power save options on the mobile stations. When a mobile station has encountered a long lull in data volume, Celona AP 22 monitors traffic volume on each flow enabled at the mobile station. When the traffic volume is zero for a duration of time, duration determined by the Celona AP 22 based on mobile capability as well as current loading in the system, Celona AP 22 enables Power Save mode on the mobile station. While in power save mode, the mobile station can turn off 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 22 in order to awaken the station. 09 ## Radio access technology Celona AP 22 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 22 is a 3GPP Release 15 compliant integrated 5G NR, operating within the 3300-4200 MHz spectrum band. AP 22 supports 2x2 MIMO (multiple-input, multiple-output), up to 256-QAM modulation and can be ceiling or wall mounted. Any Celona AP 22 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 geolocation. Model (SKU) Frequency range AP22-48 3.55-3.7 GHz AP22-78 3.3-3.8 GHz AP22-77 3.8-4.2 GHz ### Seamless session mobility If there are multiple Celona AP 22s in the system all connecting to the same Celona Edge, the Celona AP 22s can enable seamless mobility for mobile stations. The source and target Celona AP 22s 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 22 depends on several factors: - Transmit power authorized by the Spectrum Manager - Transmit power set on the Celona AP 22 by Celona Edge - Number of other APs operating on the same frequency in the geographic area - Proximity of other APs operating on a different 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 22 should provide coverage between 10,000 and 25,000 square feet. ### Transmit power The Celona AP 22 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 22 supports one sector, and the system bandwidths supported are: Model (SKU) System bandwidth AP22-48 20/40 MHz AP22-78 40/60 MHz AP22-77 40/60 MHz 10 ## Troubleshooting **System LED is not blue:** Ensure the AP 22 has a POE++ (802.11 bt) connection. POE (802.11 at) is not sufficient.
