 Con el avance de las tecnologías de red, el CBRS - **que significa Servicio de Radio de Banda Ancha para Ciudadanos** - se ha convertido en un tema de tendencia en el espacio de las telecomunicaciones. En pocas palabras, **el CBRS es un espectro de radiofrecuencias adecuado para desplegar redes 4G LTE y 5G**.

 Como resultado, las organizaciones que dependen de la conectividad inalámbrica de alta velocidad están particularmente ansiosas por aprovechar la banda de frecuencia previamente restringida de CBRS para construir redes LTE privadas.

 Los observadores del sector han dicho que "CBRS pondrá una enorme potencia de red inalámbrica en manos de las organizaciones." Con las redes LTE privadas, las empresas podrán ampliar -y en algunos casos sustituir- las redes públicas 4G y 5G que carecen del rendimiento y la fiabilidad necesarios para los casos de uso inalámbrico más avanzados de hoy en día.

+**CBRS network architecture: What goes in to building a PCN?**
+With access to an express lane for wireless connectivity, PALs are eager to establish new CBRS use cases across their organization, but to do so they must have each critical piece of a CBRS solution in place. Let’s explore those key components.
+**Cellular core**
+**The cellular core** — also known as the evolved packet core — **is the brain of the private 5G or LTE network**. This is where policies are set to determine which devices can access the network and how traffic can move throughout the network.
+**Cellular access points**
+**The cellular access point** (**CAP**) — also known as the **RAN** or **small cell** — is used to provide access to the network for edge devices such as laptops, IoT sensors, surveillance cameras, tablets, and more. The CAP works the same way a Wi-Fi access point is used to connect your television, printer, smartphone, etc. to an in-home network. By placing CAPs in various strategic locations across their work sites, companies can build a reliable, high-performing, secure wireless LAN.
+**Endpoints and private SIMs**
+**A SIM card** — whether physical or electronic — is required for authentication to CBRS-based private 5G or LTE before connected devices such as cameras, IoT sensors, and more can join the network. Organizations with a large number of SIM-based endpoints will benefit from SIM management services that enable IT teams to manage, monitor, and modify SIM cards from the same cloud-based system they use to manage their routers.
+**Creating a cohesive CBRS solution**
+With a few zipties and some elbow grease, the hood of a pickup truck might work in place of a missing hood on a sedan, but it’s likely an impermanent solution — a replacement from the original manufacturer is a much safer bet. Similarly, an ideal CBRS solution is built using components that come from a single vendor vs. taking a “Frankenstein” approach.
+When a wireless network solution including SIM cards, CAPs, and a cellular core originate from the same place, organizations unlock additional benefits such as:
+  - Orchestration of all components is handled within a single cloud-based management platform vs. a swivel-chair approach with a variety of systems that may or may not communicate well with one another.
+  - Contracts and agreements are made with one vendor vs. multiple vendors whose restrictions, requirements, and fine print may vary from one to the other.
+  - There’s a single point of contact for customer service and training.
+  - Radio frequency (RF) and Spectrum Access System (SAS) planning are typically included. These two key components of development can become very costly when managed through a separate consultant.
+Finally, because CBRS is a form of shared spectrum, finding the right partner with expertise in establishing successful CBRS solutions helps organizations gain insight into the access levels of other users in the area, ensuring their access is not competing with incumbent users or other PALs.
