How it works: Cloud native neutral host cellular coverage

Shared Spectrum

We use the Citizens Broadband Radio Service (CBRS) spectrum for coverage. The use of shared spectrum eliminates many technical complexities and removes legal burdens. It also prevents the business challenge of one network operator having to donate spectrum to mobile users of other operators and preserves their own licensed bands for dedicated macro infrastructure.

Shared Infrastructure

The network shares resources such as radios, LAN/WAN networks and broadband connections, reducing capital and operating costs, streamlining deployment, reducing environmental impact, minimizing building disruption, and optimizing operation.

Shared Operations

By definition, the network is shared by multiple entities. Operating from the cloud, InfiniG looks after the requirements and has legal agreements with each participating entity, including the Mobile Network Operators (MNOs).

CBRS and Shared Spectrum FAQs

Answers about CBRS spectrum, SAS coordination, GAA and PAL access, indoor capacity, and interference management.

What is a CBRS Spectrum Access System (SAS)?

A Spectrum Access System is a cloud-based service that coordinates the use of CBRS spectrum. It authorizes frequencies and power levels for each CBRS radio, protects higher-priority users, and can adjust assignments when local spectrum conditions change. The SAS framework was developed through coordination among industry, the FCC, and the Department of Defense to make CBRS available for commercial use while protecting federal operations.

Why is CBRS known as the Innovation Band?

CBRS is known as the Innovation Band because it introduced a shared-spectrum model that lets organizations deploy cellular networks without buying nationwide licenses. Automated spectrum coordination and widely available 4G and 5G technology opened cellular infrastructure to enterprises, schools, hospitals, manufacturers, venues, and new service providers.

How does shared spectrum work in CBRS?

CBRS shares spectrum through a three-tier access model. Incumbent federal users receive the highest protection, Priority Access License (PAL) holders receive protected access in licensed areas, and General Authorized Access (GAA) users share the remaining available spectrum. The SAS coordinates these users so the band can be reused efficiently in many locations.

Is CBRS unlicensed and unreliable?

CBRS is shared spectrum, but it is not unmanaged like conventional unlicensed Wi-Fi spectrum. Every CBRS radio must receive an active authorization, or grant, from an FCC-certified Spectrum Access System (SAS), which assigns channels and power levels while protecting higher-priority users. General Authorized Access (GAA) does not provide an individual spectrum license, but SAS coordination allows multiple local users to share available spectrum in a controlled way. InfiniG combines that coordination with professional RF design, capacity planning, continuous monitoring, and ongoing optimization to deliver dependable enterprise service.

Does CBRS provide enough capacity for an enterprise building?

Yes, CBRS provides substantial capacity for most properly designed indoor enterprise deployments. In many indoor locations, most or all of the 150 MHz band may be available, although the SAS determines actual channel availability. Network capacity also depends on building size, radio placement, user density, and traffic patterns. InfiniG sizes radios and backhaul for the site; CBRS neutral host is not positioned as a universal replacement for every extremely high-density licensed-spectrum venue.

GAA vs. PAL: Does an enterprise need a CBRS Priority Access License?

For most indoor enterprise deployments, General Authorized Access (GAA) is sufficient. The SAS coordinates available channels and power, and the building commonly provides meaningful RF isolation from nearby CBRS users. Airports, stadiums, dense outdoor campuses, highly congested locations, or critical applications may consider a Priority Access License (PAL) for additional predictability and interference protection.

What is the difference between low-band, mid-band, and high-band spectrum?

Low-band spectrum generally travels farther and penetrates buildings better but offers less capacity. Mid-band balances coverage and capacity. High-band spectrum, including millimeter wave, can deliver very high capacity over shorter distances. CBRS at 3.5 GHz is mid-band spectrum and is well suited to carefully designed indoor networks.

Why is 3.5 GHz CBRS well suited for indoor cellular coverage?

CBRS at 3.5 GHz offers a practical balance of indoor coverage and capacity. Building materials attenuate the signal, helping contain coverage and limit interaction with surrounding networks when the system is properly designed. InfiniG combines that natural isolation with RF planning, power control, and SAS coordination.

Could CBRS spectrum go away?

No current evidence suggests that enterprises should plan for CBRS to disappear. CBRS is an established FCC service with a substantial installed ecosystem across enterprise, fixed wireless, industrial, education, transportation, and hospitality deployments. No spectrum framework is literally permanent, but changing CBRS now would be highly disruptive and costly.

How does CBRS interference affect an indoor enterprise network?

Interference is a manageable RF-design consideration, not a reason to avoid CBRS. The SAS coordinates channel and power assignments, while InfiniG uses RF planning, site validation, monitoring, and optimization to manage the local radio environment. If conditions change, the network can be reconfigured.

Can an indoor CBRS network interfere with a mobile operator's macro network?

An indoor CBRS network normally does not create co-channel interference with an operator's licensed macro bands because it uses different spectrum. Coverage boundaries and mobility settings still must be engineered so devices transition cleanly between indoor and outdoor networks. If an operator also uses CBRS nearby, SAS coordination and RF design help manage the shared band. This is substantially less complex than a typical deployment using mobile-operator spectrum, which must be coordinated individually and on an ongoing basis by each operator.

Deployment, Backhaul and Security FAQs

Answers about how MCaaS is designed, installed, connected, commissioned, secured, and scaled.

Can InfiniG MCaaS use an existing business internet connection?

Yes, MCaaS can often use an existing business-class internet connection when it meets the required bandwidth, latency, reliability, security, and availability standards. A dedicated or secondary connection may be recommended for larger sites, critical operations, stronger service-level objectives, or network resiliency.

How does InfiniG protect voice and data when MCaaS uses an existing business internet connection?

InfiniG MCaaS establishes encrypted, secure connections across the internet circuit to participating mobile operators. The security of the cellular traffic and operator connection does not depend on treating the public internet as trusted. InfiniG also evaluates and monitors bandwidth, latency, jitter, packet loss, and availability; where the existing circuit cannot meet service requirements, InfiniG may recommend traffic prioritization, additional capacity, failover, or a dedicated connection.

How much internet bandwidth does an MCaaS deployment need?

There is no single bandwidth requirement for every building. InfiniG sizes backhaul based on the number of radios, expected concurrent users, traffic profile, service requirements, and growth headroom. The design also considers latency, jitter, packet loss, reliability, and failover - not only the advertised upload or download speed.

Who installs an InfiniG MCaaS network?

InfiniG resale partners coordinate with the enterprise customer or an approved installation contractor to install the MCaaS network. The partner and installer handle cabling, equipment placement, power, and construction coordination, while InfiniG provides design requirements, configuration, operator integration, commissioning, and service validation.

What is included with InfiniG MCaaS?

InfiniG MCaaS combines the CBRS radio-access network (RAN), required software and licenses, SAS coordination, mobile-operator onboarding, remote monitoring, performance management, support, and lifecycle operations. InfiniG then manages the network on an ongoing basis to help ensure proper performance for all parties. Site surveys, cabling, installation, internet connectivity, backup power, and other site-specific infrastructure are included or separately scoped through the delivery partner, depending on the proposal.

Can InfiniG provide outdoor coverage across a campus or large property?

InfiniG focuses primarily on indoor cellular coverage, where the building creates a natural RF boundary. Outdoor coverage is typically left to the mobile operators' macro networks. When a customer also requires coverage between buildings or elsewhere across a campus or large property, InfiniG can evaluate a site-specific outdoor extension based on the coverage objective, operator requirements, RF environment, and available CBRS spectrum.

Can InfiniG provide coverage in only part of a building?

Technically, yes, but partial-building coverage is generally not preferred. Mobile operators typically want the entire building covered so users receive a consistent experience and reliable access to emergency calling throughout the property. InfiniG evaluates the building, existing coverage, occupancy, and safety requirements before recommending the appropriate scope.

Can InfiniG MCaaS provide temporary cellular coverage for an event?

Technically, yes, but temporary events are generally not the best fit for MCaaS. Each participating mobile operator must complete network integration, configuration, testing, and approval, which can require significant effort relative to a short-duration deployment. InfiniG evaluates temporary requirements case by case, including the event timeline, location, desired operators, and available alternatives.

How does InfiniG MCaaS scale across many buildings?

MCaaS scales through a repeatable architecture, standardized building designs, centralized monitoring, and a common operating and management model. Enterprises can start with priority buildings, create templates by building type, and roll out in phases while viewing performance across the portfolio. Each site is still validated for local RF requirements, user demand, and backhaul.

How easy is it to add another mobile operator after deployment?

Adding another participating mobile operator is relatively simple and coordinated by InfiniG. The shared RAN is designed for multiple operators; after the operator approves and configures the site, InfiniG can activate service through the existing platform, subject to capacity, backhaul, and operator-specific requirements.

Does an enterprise need to negotiate separately with every mobile operator?

No. InfiniG handles mobile-operator participation through its operator contracts and onboarding processes, simplifying the experience for the enterprise and delivery partner. Each operator must still authorize and activate service, but the enterprise does not need to negotiate and manage a separate deployment agreement with every operator.
