    Scheduled Access vs. Random Access

    DECT NR+ supports two fundamentally different approaches regarding channel access. Understanding the difference is crucial for selecting the right solution for your application.

    Scheduled Access


    Scheduled Access uses Time Division Multiple Access (TDMA), where the base station (Fixed Termination Point) centrally assigns dedicated, recurring time slots to each device. There are no conflicts, no listening, no back-off – each device knows exactly when it can transmit. This leads to a deterministic, collision-free communication with guaranteed latency.

    The STRATUM 9 MAC layer has been specifically designed for industrial automation: AGV fleet control, real-time PLC communication, robot coordination, and all scenarios where predictable timing is not optional but essential. It enables reliable, deterministic communication with clearly defined transmission behavior, even in demanding and highly dynamic industrial environments.

    Random Access


    Random Access uses a Listen-Before-Talk (LBT) protocol with binary exponential backoff. Before transmission, each device checks if the channel is free. If it is occupied, the device waits a random period of time and tries again. This approach is well-suited for event-driven, bursty traffic – such as sensor readings or alarm messages – where devices transmit data infrequently and unpredictably.

    The star topology with Random Access is ideal for applications such as smart meters, sensor monitoring, and consumer IoT, where absolute time guarantees are less important than simplicityand broad device compatibility.
