RPMA (Random Phase Multiple Access) is wireless technology designed and built for IoT and M2M applications. This technology was developed by Ingenu, formerly known as On-Ramp Wireless, an IoT/M2M wireless startup. This LPWAN technology utilizes the unlicensed, globally available 2.4 GHz ISM (Industrial, Scientific and Medical) band. Since it is based on the 2.4 GHz band it can be easily deployed anywhere in the world. The technology offers features like low power consumption, stand-alone broadcast channel for rapid firmware updates, excellent in-building range and AES 128-bit security encryption for a variety of IoT applications.

RPMA technology provides download speeds of 31 kb/s and upload speeds of 15.6 kb/s. It is similar to Narrowband IoT (NB-IoT) but with a Maximum Coupling Loss (MCL) of 167 dB, its signals reach deep into buildings and underground. This technology is ideal for IoT/M2M applications as its low power requirements allow devices using this technology to run for 10+ years on a single charge. This makes it ideal for devices that need to be positioned in remote locations or difficult-to-reach spaces that are not attached to the power grid.

Ingenu is the creator of Machine Network™, a wireless network designed specially for machine to machine (M2M) and Internet of Things (IoT) applications. This network uses Ingenu’s proprietary LPWAN technology called Random Phase Multiple Access (RPMA).

RPMA technology can also be rolled out as a private network and is ideal for regions, where the rollout of 3GPP LPWA technologies is lagging, where cellular coverage is generally weak, or where users would like to exert full control over their network deployments.
