wireless communication signaltransmission rateradiocommunication

Overview
The Field Test Device (FTD) is a portable instrument to qualify and validate IoT radio coverage within a geographic area. Offered in LoRaWAN and Sigfox regional variants, it supports site assessment during project studies and on‑site validation of network presence at planned sensor locations.

Key points / Highlights

• Immediate display of coverage metrics: radio power, RSSI, SNR, PER, UL/DL channels.
• Geolocation of measurement points for mapping and reporting.
• Widely used and referenced by public network operators for field qualification.
• Suitable for radio‑mapping, coverage verification and pre‑deployment validation.
