Overview of Technical Streams

A technical stream is created automatically when a new device is initialized or when a template is applied. Alternatively, you can manually create technical streams without reapplying a template. These streams provide essential data about the device's health and operation.

Default Technical Streams for New Devices

  • GSM

  • GPS

  • Battery

  • Humidity

  • Communication Status

Additional streams are listed in the Stream Management table under the device’s Configuration tab.

Technical Stream Types

GSM (Signal Strength)

  • Description: Modem signal strength for cellular transmission.

  • Values:

    • Excellent: > -64 dBm

    • Good: -79 to -65 dBm

    • Moderate: -89 to -80 dBm

    • Weak: -99 to -90 dBm

    • Very Weak: ≤ -100 dBm

  • Tip: Ignore values of +85; this is a known issue in 4G networks.

GSM Signal Strength %

  • Description: Signal strength as a percentage.

  • Values:

    • Excellent: 75–100%

    • Good: 55–75%

    • Moderate: 45–55%

    • Poor: 0–45%

GSM RSRP (Reference Signal Received Power)

  • Description: Modem signal strength for LTE networks.

  • Values:

    • Excellent: ≥ -80 dBm

    • Good: -80 to -90 dBm

    • Midway: -90 to -100 dBm

    • Edge: ≤ -100 dBm

GSM RSRQ (Reference Signal Received Quality)

  • Description: Signal quality for LTE networks.

  • Values:

    • Excellent: ≥ -10 dBm

    • Good: -10 to -15 dBm

    • Midway: -15 to -20 dBm

    • Edge: ≤ -20 dBm

GPS

  • Description: Provides geolocation and time data.

  • Values:

    • Latitude/Longitude: Degrees

    • Altitude: Meters from mean sea level

    • HDOP (Precision): Horizontal dilution of precision

  • Note: GPS updates occur during a reboot, magnetic key swipe, or monthly.

Battery Life

  • Description: Remaining battery life in percentage, based on usage patterns.

  • Recommendation: Replace battery when life reaches 30%.

Communication Status

  • Description: Displays the device's communication status.

    • Delayed Transmission: Transmission didn’t occur 2+ hours after the scheduled interval.

    • Interrupted Transmission: Transmission fails for 3+ days.

Power Source

  • Description: Monitors transitions between internal battery and external power sources.

  • Alert: Alerts can be configured for power source changes.

Internal Humidity

  • Description: Measures device moisture penetration.

  • Values:

    • Preferred: < 30%

    • Acceptable: Up to 70%

  • Action: Replace desiccants if humidity exceeds 70%.

Internal Temperature

  • Description: Temperature inside the device.

  • Values:

    • Acceptable Range: -40°C to 80°C

Voltage (Battery and External Power)

  • Internal Battery Voltage: Voltage produced by the battery

  • External Power Voltage: Voltage supplied by an external source

  • VBAT (Voltage at Battery): Power used during sampling and transmission
