Designing a miniaturized LTE-M antenna quickly runs into the Chu-Harrington limit. Harald Naumann explains why development costs rise exponentially as PCB size shrinks – and how just 10 mm more board length can save €70,000 in engineering effort.
IoT battery life: Five factors determine whether your trackers deliver what the datasheet promises – transmission interval, network quality, sleep modes, temperature, and protocol choice. What decision-makers need to know about PSM, eDRX, Exponential Backoff, and battery chemistry before buying.
Murata has introduced the “Type 1SC,” a new LPWA module that, for the first time, combines iSIM functionality (integrated SIM) with pre-installed global connectivity from 1NCE. The “Type 1SC” module supports both LTE-M and NB-IoT and is network-compatible in 173 countries. By deeply integrating 1NCE’s cloud-based connectivity directly into the module, the traditional SIM provisioning process is eliminated. This allows manufacturers and developers to benefit from simplified device development, lower integration costs, and faster time to market.
Sercomm introduces the TPM530M, a highly compact LTE-M/NB-IoT module built on Nordic Semiconductor’s nRF9120 SoC. With ultra-low power consumption and rich connectivity features, it targets space-constrained IoT use cases from smart cities to asset tracking.
