• VSWR, Return Loss and S11: What the Numbers Mean for an IoT Antenna — VSWR, return loss and S11 are three views of one defect — reflected power. VSWR 2.0 costs only 0.51 dB of mismatch loss, so the number that really matters is whether the antenna stays matched across the band in your enclosure, not whether it hits
• 4G LTE and 5G NR Band Frequency Table (with China allocations) — Uplink and downlink ranges for the mainstream LTE FDD/TDD bands and 5G NR FR1 bands, plus the Chinese operator allocations. Use it to check whether a wideband '4G/5G antenna' really covers the bands your modem will
• IoT Connectivity in 2026: What the LPWAN Mix Means for Antenna Buyers — Roughly 21 billion IoT connections are in service, with NB-IoT and LTE Cat-1 bis leading module shipments and LoRaWAN at 125 million devices outside China. The practical consequence for antenna sourcing: multi-mode, multi-region products, not single-band
• Smart Metering Antennas in 2026: The EED Deadline, Pit Installations and 10-Year Batteries — Metering is the highest-volume, longest-lived antenna application in LPWAN. The EU requires existing meters to be remotely readable by 1 January 2027, China Southern Power Grid runs over 130 million meters at 99.68% automatic reading — and the antenna is the component that decides whether a 10-year battery
