As the name suggested, Sub-1GHz wireless technologies work below 1GHz such as 433, 512, 868 and 920 MHz, it offers higher range as compared to 2.4GHz technologies such as Bluetooth and Wi-Fi. They are used to connect IoT devices directly to infrastructure without the need of gateway at consumer's end. They are used for Sensors to Cloud, Asset tracking, Smart metering, Home energy management systems, Wireless alarm systems, Smart home, Building automation, Industrial monitoring and control, Smart lighting systems, LPWAN such as Sigfox etc.

In this webinar series, we will introduce the Sub-1GHz technology based on SPIRIT1 family and its usage. Various tools and available design packages will be discussed. We will also have dedicated session for 6LoWPAN mesh.

Product details:

The S2-LP is a high performance ultra-low power RF transceiver, intended for RF wireless applications in the Sub-1GHz band. It is designed to operate in both the license-free ISM and SRD frequency bands at 433, 512, 868 and 920 MHz, but can also be programmed to operate at other additional frequencies in the 413-479 MHz, 452-527 MHz, 826-958 MH, 904-1055 MHz bands.

The S2-LP supports different modulation schemes: 2(G)FSK, 4(G)FSK, OOK and ASK. The air data rate is programmable from 0.1 to 500 kbps.

The S2-LP can be used in systems with channel spacing down to 1 kHz enabling the narrow band operations.

The S2-LP shows an RF link budget higher than 140 dB for long communication ranges and meets the regulatory requirements applicable in territories worldwide, including Europe, Japan, China and the USA.
