Gplus-IoT Sub-1 GHz Module Series, Complete Your IoT Dream

Sub-1 GHz, also known as Sub-GHz, refers to the wireless connectivity technology in the radio frequency (RF) range of less than 1 GHz. It contains several frequency bands which are widely applied worldwide. Since Sub-1 GHz technology is a long range transmission and low power consumption solution, there are multiple benefits to use it for specific wireless connectivity applications.

Based on various designs, Sub-1 GHz technology could support the network which operates at the ISM/SRD license-free and less crowded frequency bands of 315, 426, 433, 868, 915 MHz, etc. Furthermore, with low data rates, the transmission distance of a Sub-1 GHz network could reach several kilometers, and the end-node devices usually consume extremely low power. For instance, a flow meter monitor or sensor node could operate on a button-cell battery for 10 years or so.

In response to the features of Sub-1 GHz technology, markets such as automation (including industrial, home and building automation), smart grid and metering, alarm and security are suitable to implement with Sub-1 GHz solution due to their characteristic of low power consumption and requirement of long distance transmission.

STMicroelectronics (ST) and Texas Instruments (TI) are two important suppliers providing Sub-1 GHz solutions that GPlus-IoT uses to build up the Sub-1 GHz modules, which includes RF transceiver S2-LP (ST), SPIRIT1 (ST), CC1101 (TI) and microcontroller CC1310F128 (TI). The high performance S2-LP and SPIRIT1 RF transceivers are with ultra-low power and support advanced technologies like frequency hopping, auto-acknowledgment and antenna diversity. The cost-effective CC1310F128 microcontroller is ultra-low power as it combines a RF transceiver with a 40 MHz Cortex-M3 microcontroller.
