Sapphire PCN · Private Cellular Network
Your private 5G cellular network.
Dedicated private 5G/LTE infrastructure for your installation, designed and operated by DHI. Connect authorized people and devices for data, voice and IoT, with access and traffic policies under your control.
Sapphire PCN is approved by The Exchange.
Your site. Your network. Your rules.
PCN means Private Cellular Network. Sapphire brings dedicated radios, a cellular core and access controls to your installation, so you can define coverage and authorize devices without relying on a public mobile operator’s local network.
Your private cellular network · Authorized access only
Approved SIMs and eSIMs connect compatible devices to your network.
Private LTE/5G coverage, device authentication and traffic policies operated by DHI.
Fiber, satellite or a hybrid design connects the private network to external services where required.
Private radio access operates independently of a public mobile operator’s local coverage. Voice services, device support and traffic routing follow the agreed network configuration.
Connect people and operations
Provide private cellular access for approved phones, computers, hotspots and operational applications across the site.
Support team communications
Carry voice services over your private network, configured for compatible devices and your communication requirements.
Connect devices and equipment
Bring cameras, sensors and other approved connected equipment into defined service groups with their own access and traffic policies.
Only authorized devices can join. A nearby phone cannot simply register on your private network. DHI provisions and manages the SIM/eSIM credentials and policies used to grant, change or revoke access.
Control the network. Govern access.
Direct control over who connects, how traffic flows, and what stays local — physically separate from DoD mission systems.
Separation by architecture, not by policy memo.
Personal traffic never routes across NIPR, SIPR, or other mission systems. Access is identity-based and centrally revocable; traffic handling is U.S.-anchored or governed under agreed terms.
A1 Identity-based access
Users and devices authenticate through SIM or eSIM credentials. Access can be granted, denied, changed, or revoked centrally.
A2 Segmentation
Distinct APNs, slices, or logical traffic domains for soldiers, families, Exchange operations, MWR, USO, contractors, and IoT — each with its own policy.
A3 Architectural separation
Physically and logically separate from DoD mission networks. Personal traffic never routes across NIPR, SIPR, or other mission systems.
A4 Traffic governance
Full operator visibility into who is connecting, their service class, and how resources are being used — a more disciplined posture than public-only.
A5 Local traffic handling
Traffic can be U.S.-anchored or managed under agreed governance. The operator controls what stays local and what routes through controlled gateways.
The platform, layer by layer
Purpose-built from the radio equipment to the helpdesk.
Not dependent on a single path
Fiber for capacity, satellite for resilience and reach — hybrid where continuity matters most.
Fiber
Primary high-capacity backhaul for main sites where terrestrial infrastructure is available and stable.
Satellite
Rapid deployment, augmentation, or remote-site option where terrestrial links are limited or resilience is needed quickly.
Fiber + Satellite
Hybrid design for resilience, graceful degradation, and service continuity if one path is constrained.
Hybrid backhaul — satellite augmentationService beyond the private network
Private site access and off-site mobility are different services. Where configured, the same customer app can also support public-carrier plans and international roaming outside the installation.
Private on site. Carrier service off site. Off-site coverage uses supported public operators and destination plans; profile selection and availability follow the deployment configuration.
Designed around the installation
Five phases, one accountable operator — from site survey through lifecycle support.
Site survey & design
Outdoor zones, indoor buildings, RF conditions, power, backhaul, and device requirements.
Radio installation
Towers, sector radios, small cells, or indoor access points — per the site design.
Core & policy activation
Activate the agreed core architecture, authentication, segmentation and traffic routing.
User enablement
SIM/eSIM profiles, app credentials, and device options for barracks, lodging, and offices.
Operations & support
Performance, alarms, utilization, and customer support through one managed service model.
Sapphire Flyaway Kit
The same platform — governance, policy engine, SIM identity, app — in three portable cases. Operational the same day.
Flyaway Kit specificationsOne accountable operator
DHI designs, deploys, monitors, supports, and manages the full Sapphire PCN lifecycle — a single accountable partner from site survey to daily operations. No finger-pointing between vendors.
