Read the first 6 CTE Emerging Technologies & Innovation flashcards as text

  1. What does eSIM (embedded SIM) technology offer US consumers and enterprise IoT deployments compared to traditional physical SIM cards?

    Answer: Remote provisioning of operator profiles without physical SIM swap

    eSIM enables over-the-air provisioning and switching of carrier profiles, eliminating the need for physical SIM cards and enabling seamless carrier changes for consumers and IoT devices.

  2. A CTE must evaluate low-earth orbit (LEO) satellite connectivity as a supplement to terrestrial networks in rural US markets. What is the primary technical challenge of LEO constellations compared to geostationary (GEO) satellites?

    Answer: Handoff management between rapidly moving satellites and ground stations

    LEO satellites orbit at ~500–1,200 km altitude and move rapidly relative to Earth, requiring constant handoffs between satellites and sophisticated ground station tracking to maintain continuous connectivity.

  3. In the context of telecom innovation, what is the primary purpose of a Telco API platform (such as GSMA Open Gateway)?

    Answer: To expose carrier network capabilities like QoD, SIM swap detection, and number verification to developers via standardized APIs

    Telco API platforms like GSMA Open Gateway standardize access to network capabilities (quality on demand, SIM swap alerts, device status) enabling developers to build value-added services on top of carrier networks.

  4. Which virtualization technology allows multiple isolated operating system instances to run on a single physical server, fundamental to NFV (Network Functions Virtualization) in telecom?

    Answer: Hypervisor-based virtualization (e.g., KVM, VMware)

    Hypervisors like KVM and VMware ESXi create virtual machines that allow multiple isolated instances of network functions (vEPC, vIMS, vBNG) to run on standard commercial off-the-shelf servers.

  5. What is the role of an AI-powered RAN Intelligent Controller (RIC) in O-RAN architecture?

    Answer: To apply ML-based optimization to RAN parameters like handover thresholds and load balancing in near-real-time

    The RIC (both near-RT and non-RT) applies AI/ML algorithms to RAN telemetry data to dynamically optimize radio parameters, enabling intelligent, self-optimizing networks.

  6. A US telecom CTE is planning a quantum-safe cryptography migration. What drives this urgency for long-haul fiber transport networks?

    Answer: Adversaries may harvest encrypted traffic today to decrypt it once quantum computers become available (harvest now, decrypt later)

    The 'harvest now, decrypt later' threat means sensitive encrypted traffic intercepted today could be decrypted once cryptographically relevant quantum computers exist, making migration to post-quantum algorithms urgent for long-lived data.
