A Sub-GHz SoC is a wireless LSI that integrates a microcontroller and a radio operating a frequency of below 1 GHz.
LAPIS Technology offers a lineup of SoC products that combine original 16-bit CPU cores and ARM cores depending on the application.
Smart-meter / telemeter
Its low power consumption and ability of long distance communication enables telemeter applications. If meters (Gas or Electric etc.) have an unit with UHF communication technology, meter readers can gather data of each unit without visiting the actual units. This technology is also applied to telemetering vending machines or observing units used for weather forecasts.
Home and building security
Security systems such as lock control, fire alarm, intrusion detection/report system applies UHF technology.
Tracking to confirm the location of things requires communication links over a wide area. Sigfox, one of the LPWA systems, is ideal because it has a wide service network.
