Ingenu Random Phase Multiple Access (RPMA) technology is used for M2M/IoT connections.
RPMA operates with 2.4GHz band, offering 80MHz bandwidth. To support the network, a 1MHz signal is required. The bandwidth of the RPMA offers huge advantages – the technology can support up to 40 channels simultaneously.
The basic layer of the technology code uses the Viterbi algorithm. Access points and end-points are synchronised. The end-points send signals with random delay time, which is very small, so the frame size is not exceeded.
The signal has several steps – the signal is de-spread, de-interleaved, decoded and checked via CRC. End-points also unilaterally calculate the optimal spreading factor. However, the access point usually doesn’t need to know the spreading factor in advance.
RPMA end-points constantly check the channel conditions and interference levels. This data is sent back to the access point with a downlink signal. Downlink capacity is amplified 30 times relative to the worst case spreading factor.
Ingenu RPMA offers greater security with 128-bit encryption and two-way authentication. Now Ingenu RPMA is deployed in the US, growing its network.
