Crucial to devices such as ours is the Sub-1 GHz transceiver. We definitely wanted to employ a transceiver that is capable throughout a wide range of frequencies. (Refer to Frequency Range in chart below). The Si4463 transceiver boasts optimal sensitivity, allowing it to discern even very faint signals. Additionally, its robust power output ensures extended range communication capabilities. And it’s nice to have data rates up to 1 megabyte per second as opposed to only 500 kilobytes per second.
