Whatever the nature or purpose of a network, there is today a wireless connectivity technology – most often a standard – that is optimized to fit its specific range, energy per bit and bandwidth requirements. With the growing importance of wireless sensor networks and even more broadly of the Internet of Things, there’ s virtually no electronic system that does not requires wireless connectivity. ST’s portfolio includes a variety of RF transceivers, network processor ICs and fully certified modules that support major technologies for wireless connectivity including sub-1GHz long-range networks (6LowPan, WMBUS, SigFox and LoRaWAN), Bluetooth-Smart® and LTE Cat 1 and Narrowband IoT (NB-IoT).
