Qualcomm Technologies, ZTE and China Mobile have announced a successful demonstration of the world’s first end-to-end 5G NR Interoperability Data Testing (IoDT) system, establishing a data connection based on the 3GPP Release 15 (R15) standard.
The demonstrated end-to-end 5G New Radio (NR) system operates in the 3.5 GHz band and supports a 100 MHz channel bandwidth. It complies with the 3GPP Release-15 5G NR Layer 1 framework, which includes scalable OFDM numerology, advanced channel coding and modulation schemes, and a low‑latency self-contained slot structure. This IoDT implementation is designed to deliver multi‑gigabit-per-second peak data rates and substantially lower air-interface latency compared with 4G networks, supporting the performance targets set for early 5G deployments.
Cristiano Amon, executive vice president at Qualcomm, said the achievement underscores the company’s leadership in 5G and helps accelerate the timely launch of standard-compliant commercial networks. He emphasized Qualcomm Technologies’ commitment to supporting the growth of China’s wireless industry and highlighted the collaboration with ZTE and China Mobile as an important step toward broader 5G adoption across the region.
Qualcomm notes that implementing 5G NR technologies is a critical response to growing connectivity demands. Beyond faster mobile broadband—such as streaming higher-resolution video and enabling richer virtual and augmented reality experiences—5G NR aims to support new classes of services that require high reliability and low latency. These include use cases in autonomous vehicles, unmanned aerial systems (drones) and industrial control, where deterministic performance and rapid response times are essential.
The announcement arrives as multiple vendors advance commercial 5G modem and infrastructure solutions. For example, Intel recently introduced two modem families targeting rapid 5G adoption: the XMM 8000 series and the XMM 7660. The XMM 8000 series represents Intel’s first family of 5G NR multi‑mode commercial modems, capable of operating across both sub‑6 GHz and millimeter‑wave spectrum bands and intended for a variety of devices—including smartphones, PCs, fixed wireless consumer premises equipment (CPE) and connected vehicles. The XMM 7660 is an LTE modem positioned as a commercial offering that supports multi‑mode operation across 5G non‑standalone (NSA) and standalone (SA) NR modes plus legacy 2G, 3G (including CDMA) and 4G networks, helping bridge existing networks with emerging 5G deployments.
As vendors, operators and device makers continue interoperability testing and field trials, achieving end‑to‑end 5G NR connections that conform to 3GPP standards is a key milestone on the path to broader commercial rollout. Interoperability demonstrations such as this one help validate the end‑to‑end ecosystem—from radio access network elements and core network functions to device modems—ensuring that the performance, efficiency and latency improvements promised by 5G can be realized in real deployments.
Moving forward, participants in the 5G ecosystem will focus on expanding spectrum utilization, optimizing network architecture and device implementations, and scaling trials to support a wide variety of consumer and enterprise applications. Continued collaboration between chipset vendors, equipment manufacturers and network operators will remain essential to meet the technical and operational requirements needed for robust, large‑scale 5G services.
