• Cellular Communication Module (Mobile Network)

Application scenarios: Mobile POS, outdoor payments, food delivery – environments without fixed network infrastructure.

In such scenarios, devices are highly mobile and rely on cellular networks for wide coverage and plug‑and‑play connectivity. Cellular networks, with extensive base station coverage, provide stable connections in open areas, temporary venues, and along delivery routes. Mobile POS devices equipped with cellular modules automatically connect upon power‑on, enabling fast transactions anywhere.

For 2G/3G/4G/5G cellular modules, the WELZEK T6290 series testers support GSM, CDMA, WCDMA, LTE, NR, and other standards.

• Wi‑Fi Module

Applicable scenarios: Malls, restaurants, and other environments with fixed broadband.

Wi‑Fi offers high data rates and stable connectivity, making it ideal for POS terminals in fixed indoor settings such as shopping malls, restaurants, and convenience stores. In these scenarios, the store provides reliable Wi‑Fi, reducing mobile data costs while ensuring fast transaction processing (payments, order verification) and improving the consumer payment experience.

The WELZEK T6290 series tester supports Wi‑Fi IEEE 802.11 a/b/g/n/ac/ax/be and tri‑band testing (2.4G/5G/6G).

• Bluetooth Module

Applicable scenario: Connecting peripherals

Low‑energy Bluetooth, with short‑range communication (10–100 m), enables efficient and convenient POS payment experiences while maintaining low power consumption. POS terminals equipped with Bluetooth can wirelessly connect to barcode scanners, thermal printers, smart cash drawers, etc., ensuring seamless coordination for scanning, payment, receipt printing, and cash management.

The WELZEK T6290 series not only supports common BLE 4.0/5.0/5.2 but also the latest Bluetooth 6.0 Channel Sounding testing.

• GNSS (GPS/Beidou) Module

Applicable scenarios: Mobile payments, in-vehicle POS, logistics signature

POS terminals equipped with GPS/Beidou modules enable critical functions for mobile scenarios: transaction location tracking for source traceability, tamper‑proof monitoring to detect unauthorized disassembly, and route tracking for dynamic device management. These features enhance security, data authenticity, and operational efficiency for merchants and logistics.

The WELZEK T6290 series supports GNSS signal testing, including dual‑frequency testing across all bands of GPS, Beidou, and other navigation systems.
