How to Simplify Complex Private Cellular Network Deployments – Timing, Data, and Power

CBRS private cellular networks employ sophisticated time division duplexing (TDD) techniques to efficiently manage uplink and downlink communications on the same frequency band. Driven by the Precision Time Protocol (PTP), this process traditionally required a dedicated PTP Grandmaster appliance, PTP passthrough switch, and GPS antenna. Similarly, multiple Power over Ethernet (PoE++) injectors powered radio units and other edge devices across campuses and facilities.

Once considered essential for private cellular networks, the use of disparate infrastructure can complicate network integration, involving multiple on-site vendor equipment, requiring additional interoperability efforts, and significantly increasing installation costs.

This blog discusses how the Moso Concord smart Ethernet switch simplifies private cellular network deployments by cost-effectively combining timing, data, and power into a single edge device. It also highlights key specifications, reviews operational benefits, and explores applications and use cases.

Streamlining Network Management with the Moso Concord Smart Ethernet Switch
The Moso Concord smart Ethernet switch integrates a PTP IEEE 1588v2 Grandmaster clock, eliminating the need for separate external timing devices and GPS antennas. Essential for indoor CBRS private cellular network deployments, PTP has traditionally presented significant challenges, both during installation and in maintaining network stability over time. Moso Concord uniquely offers reliable PTP timing for networks without requiring its own GPS reference signal, allowing flexible placement anywhere in a building, including discreet locations like a networking closet.    In more complex deployments, the switch can still easily accommodate GPS antennas for synchronization or backup.

The Moso Concord all-in-one approach simplifies the deployment of private cellular networks by reducing the number of individual components needed. Crucially, it also cuts costs and minimizes the risk of synchronization issues that can interrupt network operations.

On the power side, the Moso Concord reduces reliance on external PoE injectors by offering 24 PoE++ 2.5GE Ethernet ports. Each port, conforming to the IEEE 802.3bt standard, can provide up to 90 watts and directly power a diverse array of edge devices including Moso Canopy radios. This integration streamlines the network’s physical infrastructure and improves power management efficiency.

The Moso Concord offers a total data capacity of 270Gbps, which includes 242.5Gbps Ethernet ports, 2SFP+ ports, and 4*SFP28 uplink ports, with each supporting up to 25Gbps. The integrated PTP passthrough capability eliminates the need for additional data management switches, ensuring a reliable flow of PTP packets across the network.

Lastly, the Moso Concord’s user interface (UI) enables centralized and effective management of both switch settings and timing configurations. It empowers IT teams to proactively monitor and address issues via comprehensive dashboards, leading to fewer helpdesk calls, minimal physical maintenance and repairs, and faster time to resolution (TTR).

Exploring Applications and Use Cases
Seamlessly integrating with both Moso Canopy radios or other radio vendors, Moso Concord simplifies the setup and maintenance of private cellular networks across a diverse set of applications. It efficiently supports environments such as factories and warehouses that use automated guided vehicles (AGVs), autonomous mobile robots (AMRs), and automated storage and retrieval systems (AS/RS). For airports and educational campuses, the smart switch enables reliable, high-speed connectivity, facilitating operational efficiency and advanced digital learning. Additionally, Moso Concord accommodates large venues, including stadiums and hotel convention centers that prefer neutral host networks over Distributed Antenna Systems (DAS), as you can connect Moso Concords together as needed for backup and large network topologies.

Supporting PTP and time synchronization without a GPS reference, Moso Concord operates effectively in areas with compromised GPS signals, critical  for most building deployments, particularly those where roof access is limited or impossible. Its integrated PTP timing is also crucial in underground facilities or in  densely built-up urban areas where conventional GPS-based timing isn’t an option.

Summary

The Moso Concord smart Ethernet switch integrates timing, power, and data into a single edge device. This integration simplifies complex deployments and accelerates the adoption of efficient and cost-effective private cellular networks. The Moso Concord is available for sampling today.
