Every wireless technology has trade-offs. Here are common pitfalls we help customers avoid.
Our modules are rated for -40°C to +85°C operating temperature, but RF output power derates by approximately 1-2 dB at temperature extremes. For outdoor deployments in desert or arctic environments, factor this derating into your link budget calculations. We publish temperature-dependent RF performance curves in each module's hardware design guide.
While our modules carry 200+ carrier certifications globally, not every module is certified on every regional carrier. For example, NB-IoT coverage varies significantly between Band 8 (900 MHz, common in Europe) and Band 28 (700 MHz, common in Asia-Pacific). Always verify band support and certification status for your target region using our Module Compatibility Checker before committing to a design.
Module performance is only as good as its antenna system. On-board chip antennas sacrifice 2-4 dBi gain compared to external antennas but save PCB space. For products with metal enclosures, external antenna connectors (U.FL or SMA) are typically required — internal antennas will suffer 6-10 dB attenuation through metal housings. Our antenna application notes include reference layouts for common enclosure types.
Published PSM current figures (typically 1-3 μA) represent the module's sleep current only. Total system power depends on your host MCU, sensors, and voltage regulator efficiency. In our testing, real-world LPWA devices with a BG95 module and typical sensor payload average 15-25 μA total system current — 5-10x higher than module-only specs. We provide current profiling templates and measurement guides to help you estimate realistic battery life.
