There are a variety of standard wireless communications technologies used for communications and to connect IoT devices. In addition to Bluetooth? and Bluetooth Low Energy (LE), cellular wireless connectivity based on the 3GPP LTE standard along with Wi-Fi and ultra-wideband (UWB) solutions provide additional short-range communication technology options.
Renesas has developed microcontroller-based Bluetooth and Bluetooth Low Energy devices since the standards were established and continues deploying new communication options and technologies. Several MCUs are available in chipset and complete certified module versions, including RL78/G1D, RX23W and RA4W1, as well as the RYZ014A cellular IoT module.
