Stable data connection at 120 km/h

Graphical summary of the results of a test drive
Figure 5. Graphical summary of the results of a test drive at around 120 km/h: Good radio connections were measured even in zones with poor simulated radio coverage (red) (green and yellow marked drive sections in the red map area). For measured values, see Figure 6.

Thanks to the Telegram splitting method, Mioty can be used to transmit data very robustly with a long range and at high speeds. »The robustness of the protocol has also been confirmed during test drives on the motorway at over 120 km/h relative speed between the vehicle and the base station,« says Swissphone's CTO Harald Pfurtscheller. A key finding for future mobile Mioty applications.

Even in zones where simulations suggest poor radio coverage, good radio links were measured during a test drive with transmitters in moving vehicles.

Measurement data from the drive
Figure 6. Measurement data from the drive shown in Figure 5: Despite a relative speed of the measurement vehicle of up to 120 km/h to the base station (turquoise), no transmission packets were lost. Even in extreme areas with high distances to the base station and low RSSI values, signals can still be received with Mioty at high speeds.

They are marked in green and yellow driving sections in the red zones in Figure 5. Even in extreme areas with high distances of the vehicle to the base station and low RSSI values, signals can still be received with Mioty at high relative speeds of the vehicle to the base station (Figure 6).

Two terrain cross-sections with base station and measurement point illustrate the challenging measurement conditions (S1 and S2 in Figure 5, 7 and 8). The fact that the functionality has also been demonstrated for mobile or portable scenarios is relevant, among other things, for future use cases in the alerting and monitoring context.
