Solution Overview

Most private wireless networks today use Wi-Fi as it is fast and easy to deploy. In many cases, Wi-Fi will remain a good solution. Private LTE is based on technologies developed for wide-area mobility and scaled down to be deployable by private organizations. This gives LTE some advantages over Wi-Fi particularly as it relates to performance and mobility that can help address more demanding use cases.

Service providers are using Citizens Broadband Radio Service (CBRS) to replace last-mile fiber access and deliver fixed wireless services to end customers while augmenting existing capacity. Enterprises and managed service providers can utilize the 3.5 GHz band to deploy private LTE for IoT connectivity and deliver a quality of experience that Wi-Fi cannot guarantee. With indoor LTE speeds theoretically reaching 1 Gbps, the economics of the technology are much better than those of distributed antenna systems, according to CBRS experts, with better speed and consistency of service than Wi-Fi.

Enterprises undergoing digital transformation can use CBRS to improve in-building Wi-Fi connectivity with a private LTE network. This high-speed, low-latency local area network allows them to connect all devices and "things" (robots, drones, sensors, machinery, buildings), automate operations, gain insights from customers and invent new business models that position them to lead the digital economy.

The WWT ATC Private LTE (over CBRS) network solution consists of two parallel labs, with components from the following industry-leading partners:

Lab1: Our solution is comprised of CORE and RAN components, shown in the matrix above, where JMA Wireless is the xRAN provider. DRUID delivers a light-weight all-in-one service including a virtual, evolved packet core, IP multimedia system and home subscriber server for subscriber management, within a single virtual machine.

Lab2: Our solution is comprised of the CORE and RAN components, shown in the matrix above. VMware vSphere, (with SR-IOV enabled interfaces), hosts the virtual evolved packet core. The virtual evolved packet core provides Control and User Plane Separation(CUPS) virtual machines, along with a Home Subscriber Server provided by NetNumber, to provide subscriber Management. This lab is useful to highlight use cases that require low latency and high throughput.

Before You Get Started

CBRS offers organizations a new way of deploying wireless, and it has a path forward with 5G specs in the works. Still, planning is key. And well-defined use cases -- anything from better connectivity to supporting augmented reality -- will be important.
