Unlocking the value of network slicing

5G networks open up a host of new possibilities for mobile network operators. Three very distinct initial capabilities are envisioned for 5G networks: enhanced mobile broadband, with high capacity and gigabits-per-second speeds; ultra-reliable and low-latency communications; and massive machine-type communications to support the internet of...

EXFO Case Study: A new approach to quickly diagnose RF interference and PIM issues

The MNO’s RAN performance team noticed that the operations support system (OSS) flagged the presence of an RF noise issue in the network based on high uplink (UL) received signal strength indicator (RSSI) levels. In order to take a closer look and attempt to diagnose...

Understanding the Basics of Mobile Fronthaul Technology

Mobile network operators (MNOs) have been driven to upgrade their cell towers through fierce competition to provide higher bandwidth and quality of service. Typical Internet traffic has been constantly increasing. Mobile video traffic by the usual suspects—YouTube, Vine, Netflix, just to name a few—is...

The path to 5G requires a strong optical network

This white paper reviews the latest trends in the radio access networks (RANs) of mobile networks, including the evolution to Cloud-RAN, virtualized architectures. Although it can be difficult to make accurate predictions for some technologies, we are fortunate in the case of future RAN...

Why C-RAN deployments will give you more headaches than D-RAN rollouts

Each step in the evolution of radio access networks (RANs) brings unique opportunities and challenges for mobile network operators. Today, fiber has mostly replaced coaxial cables in new mobile fronthaul builds, otherwise known as fiber-to-the-antenna (FTTA). The next technological innovation in mobile fronthaul is...

Remote access and monitoring of fiber-based fronthaul networks

Mobile network operators (MNOs) are expanding their fronthaul networks to get ready for 5G. As more RRHs are deployed, the number of RF signals and fiber optic connections being monitored—and trouble tickets being generated—will skyrocket. All that change means field technician workloads are set...
