RPMA module measures 16- x 26- x 2.3-mm, draws 50 µW in sleep mode

Measuring just 16- x 26- x 2.3-mm in a Land Grid Array (LGA) package, the SARA‑S200 is what u-blox claims to be one of the smallest modules for the Machine Network, based on RPMA (Random Phase Multiple Access), a low‑power wide‑area technology.

The Machine Network is a wireless network built by Ingenu, the creators of RPMA technology, exclusively for Machine‑to‑Machine (M2M) and Internet of Things (IoT) applications. Operating in the globally license‑free 2.4 GHz ISM (Industrial, Scientific and Medical) band, RPMA is at the heart of secure wireless networks operating in over 20 countries around the world. u-blox has successfully ported the proven technology used in its first‑generation RPMA modules and made it 65 percent smaller.

Ingenu’s patented RPMA technology features excellent in-building range and AES 128bit security encryption. With autonomous adaptation, the Machine Network delivers interference‑free operation for reliable real‑world applications. SARA‑S200's low‑power design (50µW average power consumption in sleep mode) means it can operate for 10 years or longer from a single battery. The modules will be manufactured in ISO/TS 16949 certified facilities with guaranteed Quality of Service (QoS) and a secure design that meets NERC CIP and other industry‑mandated critical infrastructure requirements. The SARA‑S200 has been designed for industrial applications and comes with an extended operating temperature of -40°C to +85°C.
