RPMA
(Random Phase Multiple Access)
Integrasia Utama as a company focusing on Integrated IOT solution, we aren’t only focusing on Platform and device but also working together with Ingenu (RPMA) to be able bring reliable technology to machine to machine communication.
Ingenu’s RPMA® (Random Phase Multiple Access) meets or exceeds the data features that the industry has come to expect from cellular providers. LPWA endpoints may not require voice and video data rates, but they do require certain inalienable rights.
RPMA DELIVERS ON THE MACHINE BILL OF RIGHTS:
- Industry best security guarantees including strong authentication
- Reliable delivery on all data
- Full two-way data flow
- Flexible frame sizes
- Reliable, flexible, acknowledged delivery
- Broadcast channel for firmware downloads and other functions
When you connect to the IoT using RPMA, you get more than a simple data link. RPMA gives you a connectivity experience that allows you to use your devices to their fullest potential.
