CBRS technology enables spectrum sharing with an innovative three-tiered hierarchical TD-LTE-based implementation in 3550–3700MHz spectrum. The solution paves the way for cheaper and faster network capacity and improved coverage based on RAN densification through a combination of enterprise, carrier-, and service provider-focused use cases. It brings value to a broader ecosystem. Mobile Operators Increasingly, mobile operators are turning to the shared 3.5 GHz CBRS frequency band to deliver enhanced in-building wireless coverage, to replace last-mile fiber access for fixed wireless access services (especially for rural broadband), to provide point to multi-point offerings, and to enable new services for managed enterprise private LTE and neutral host networks. The interest in CBRS spans across all tiers of carriers—from large to small. There is an increased interest from WISPs (Wireless Internet Service Providers) as they can augment their existing service much more cost-effectively by adding spectrum through CBRS PAL (Priority Access Licenses) or GAA (General Authorized Access Licenses) options. Neutral Host Service Providers Neutral Host services, which have traditionally depended on expensive Distributed Antenna Systems (DAS), are finding new cost and operational efficiencies with CBRS small cells. Historically, small cells were tied to an operator-specific licensed spectrum, precluding them from deployment in neutral host networks to support multi-carrier connectivity. The shared spectrum capability of CBRS band untethers small cells from a carrier-only deployment and enables neutral host providers or businesses to own and manage LTE CBRS access points. This flexibility, along with the near zero cost of 3.5 GHz spectrum, creates opportunities and business models for new and existing neutral host providers. Enterprises Likewise, for enterprises, CBRS small cell-based private LTE networks will play a critical role in digital transformation supporting industrial IoT initiatives where the reliability of Wi-Fi and public LTE connectivity are not suitable to support mission-critical applications that require high predictability in network performance. For enterprise CIOs, CBRS-based private LTE business case is becoming stronger as the benefits of higher network quality, data privacy, IT autonomy, and lower capital and operational cost are very attractive. Manufacturing industries, hotels, large public venues such as sporting venues and airports, oil & gas companies, utility companies, large education campuses, and transportation industry are prime candidates for private LTE. Vendor Community From a vendor community perspective, CBRS is opening doors from non-traditional small cell players to join. For instance, Wi-Fi vendors are looking at 3.5GHz GAA as additional spectrum to augment capacity & coverage for their in-building, campus, and enterprise deployments. Consumers From a consumer standpoint, as smartphones supporting the 3.5 GHz band become increasingly available in 2019—they are likely to experience significantly better connections. As of Q1 2019, the first wave
