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
