What are the differences between iBeacon and other Bluetooth beacons?

By 谭宇on 22 जुलाई 2026

Beacon is a proprietary Bluetooth Low Energy (BLE) proximity protocol defined by Apple that locks advertising payload structures to a specific 30-byte advertising PDU format (comprising a 128-bit UUID, Major, and Minor values), optimized specifically for fixed-interval location broadcasting and iOS native wakeups. In contrast, standard Bluetooth beacons—including Google Eddystone (supporting UID, URL, and TLM telemetry) and open BLE advertising frames—offer configurable payload formats, sensor data encapsulation (temperature, humidity, accelerometer), and multi-protocol flexibility. Selection between iBeacon and open BLE beacon architectures depends on whether the target application requires seamless iOS ecosystem integration (iBeacon) or multi-data payload transmission, long-range telemetry, and cross-platform flexibility (Eddystone / Open BLE).

Long Range LoRa Modules and Transceivers

By 谭宇on 22 जुलाई 2026

Achieving reliable long-range wireless telemetry in harsh industrial environments requires optimizing link budget, receiver sensitivity, and co-channel interference rejection. Standard 2.4 GHz protocols fail under non-line-of-sight (NLOS) conditions and high attenuation, leading to lost packets and costly cabling installations. By employing Sub-GHz Chirp Spread Spectrum (CSS) modulation—specifically Semtech SX1262/SX1268 transceivers integrated into robust modules like the Ebyte E220 and E22 series—engineers can achieve sensitivity down to -148 dBm, link budgets over 168 dB, and line-of-sight transmission distances reaching up to 70 km (with high-gain directional antennas and high transmit power) or 5 to 10 km in dense industrial sites. This guide analyzes long-range LoRa hardware selection, modulation parameters, and real-world implementation strategies for legacy PLC integration, smart grids, and agricultural telemetry.

How to Read an 18650 Battery Datasheet for Industrial IoT: C-Rate, IR, & LVD

By 谭宇on 22 जुलाई 2026

Evaluating an 18650 lithium-ion battery datasheet for industrial hardware requires analyzing six primary parameters: nominal vs. cutoff voltage ($V_{nom}$ vs. $V_{cut}$), continuous/pulse discharge current (C-Rate), AC/DC internal resistance ($ESR$/$IR$), charge/discharge operating thermal envelope, cycle life retention curves, and mechanical dimensions (including protective circuit module additions). Misinterpreting these parameters leads to severe voltage sag during RF power bursts (e.g., in 1W Sub-GHz LoRa modules or LTE CAT-1 DTUs), triggering premature Low Voltage Disconnect (LVD) resets. Selecting verified industrial cells—such as Panasonic NCR18650B, Samsung INR18650-30Q, LG US18650 VTC6, or Eve LFP18650—and matching them to low-power transceiver requirements (e.g., Ebyte E220-900T22D or E840-DTU) ensures long-term operational stability across outdoor deployments.
