It’s interesting how the smallest antenna design details can be the difference between an IoT device running smoothly and supporting the infrastructure, or having no connectivity and leaving the system not working at all.
Recently, we encountered an instance in which the OEM-provided antennas did not support the lower cellular frequency bands used in Australia. This meant that the IoT device could not function, and the impact can be devastating.
In this week's video, David reveals:
🔹 The extreme case where SDR "antennas" turned out to be... well, you'll have to watch to believe it 🔹 Why your bench testing might be lying to you (hint: it has to do with radio wave power at close range) 🔹 The critical frequency that many overseas antennas miss for Australian deployments 🔹 The simple antenna swap that instantly fixed an "unsolvable" connectivity problem
Here's a teaser: The antennas worked perfectly in metro areas and probably would pass testing in Asia, Europe, or the US. But in regional Australia? Total failure. The reason comes down to one specific frequency band...
