TEST AND ANALYSE NETWORK COVERAGE This network tester provides accurate, real-time results on NB-IoT/LTE-M networks performance by measuring parameters such as RSRP, RSRQ, SNR, eDRX and transmission power. The FTD connects via Bluetooth to a mobile application that provides an intuitive user interface from which you can easily set up a network test, view the analysis results and export them. QUALIFYING AND VALIDATING CELLULAR NETWORK COVERAGE · Scan all the networks present of the various operators within range of the tester, and make a rapid initial assessment of their performance. · Test NB-IoT and/or LTE-M network coverage anywhere in the world, with any single or multi-operator nano-SIM card. · Qualify network coverage at different locations and view network quality indicators for each measurement point. · Automatically locate each measurement point. FEATURES · Simultaneous evaluation of NB-IoT and LTE-M networks. · View, store and export network test results via the mobile application. · 3 operating modes: · network scan: scan all networks and assess connection quality, · network test: select an operator and analyse network quality in detail, · radiomapping project: contextualise a network test.

D2C Tracker helps you explore Direct-to-Cell satellite coverage from your current location. View compatible satellites on an interactive 3D globe, sky dome, or horizon display. The app uses current orbital data, local terrain, RF geometry, and satellite motion to estimate which satellite is most likely to provide service. Features include: - Live 3D globe and local sky views - Likely serving-satellite estimates - Elevation, azimuth, range, Doppler, path-loss, and uplink estimates - Offline state terrain packs for line-of-sight modeling - Background location tracking and Live Activities - Data-freshness and terrain-coverage indicators - Optional low-traffic Internet link diagnostics - GPS and manual-location support - On-device orbital and terrain calculations D2C Tracker is independent software and is not affiliated with or endorsed by SpaceX, Starlink, any wireless carrier, or CelesTrak. Satellite identity, serving probability, RF performance, and connectivity quality are estimates, not modem-confirmed measurements and should not be used for navigation or safety-critical decisions.
