For cellular (and WiFi), do you also outsource your baseline RF testing?

Not all. We use spectrum analyzers and network analyzers to verify the design and high-frequency antenna performance. In addition, we conduct performance tests such as transmission distance, RSSI, number of packets received, and performance comparisons with external antennas.

For example, we compare the number of packets received by a receiver and the corresponding RSSI values against the packets sent, and then compare these results with those obtained using an external antenna.

We have extensive experience with LoRa, Bluetooth, Wi-Fi, GNSS, NB-IoT, and NTN modules as well as circuit design, all of which are used in different products of ours. We also have expertise with the LoRaWAN protocol and UWB solutions utilizing the LoRaWAN TDMA protocol.
