On March 2, MWC 2026 opened in Barcelona under the theme "The IQ Era," featuring over 2,900 exhibitors and more than 100,000 visitors from 219 countries and regions.

WELZEK, a leader in wireless communications testing, showcased professional and industry-leading test solutions at booth 5J68 in Hall 5. Live demonstrations included Wi-Fi 8, Bluetooth 6.0, the T6290F Wireless Tester, and the K6206-S Programmable Power Supply – drawing significant attention from attendees.

Cutting-Edge Wireless Test Solutions

WELZEK presented its latest test solutions for mainstream and next-generation wireless technologies, including Wi‑Fi 8, UWB IEEE 802.15.4ab, and Bluetooth 6.0. Through dynamic live demos, visitors could experience test results up close and interact with engineers.

Wi‑Fi 8 (IEEE 802.11bn) Test Solution

Wi‑Fi 8 shifts focus from peak data rates to ultra-high reliability in complex real-world environments. Key technologies include multi-AP coordination, distributed resource units (DRU), unequal modulation (UEQM), and extended long range (ELR) – enabling ultra-low latency and stable connectivity under high-density concurrency. This greatly benefits immersive interactive applications (e.g., AR/VR cloud gaming), multi-device smart homes, and industrial automation.

The WELZEK T6290 series wireless tester offers large bandwidth and wide frequency coverage, supporting R&D and production testing for Wi‑Fi 8 devices. A single unit supports 2x2 MIMO; cascading enables 4x4, 8x8, and 16x16 MIMO testing.

UWB (IEEE 802.15.4ab) Test Solution

UWB (IEEE 802.15.4ab) evolves from "accurate connection" to "stable and secure connection" in complex environments, featuring ultra-high ranging accuracy, strong link budget, and enhanced security. Leveraging the next-generation PHY and protocol optimizations combined with MMS (Multi-Millisecond) technology, it significantly improves anti-interference capability and coverage – providing critical support for indoor high-precision positioning, smart cockpit (CPD), digital keys, and more.

The WELZEK T6290F tester supports all UWB channels (CH0–CH15) and various bandwidths, covering all test types: OTA, AOA, and TOF. It is also certified for all test items of the FiRa PHY Conformance Test versions 1.0–4.0.

Bluetooth 6.0 Test Solution

Bluetooth 6.0 (BLE) introduces Channel Sounding, upgrading traditional Bluetooth from "stable connection" to "accurate and secure ranging." This technology combines phase-based ranging (PBR) and round-trip time (RTT) to achieve decimeter-level accuracy within 100 meters, with built-in encryption to protect against relay attacks – ensuring distance measurement integrity and security. This enables centimeter-level ranging for digital keys, smart locks, TWS earbuds, smart tags, and more.

The WELZEK T6290 series tester supports classic Bluetooth, BLE, and Bluetooth 6.0 Channel Sounding, covering all latest Bluetooth 6.0 features. It also supports Bluetooth OTA signaling mode testing.
