Android Device Cellular Network Performance Metrics

SysTrack can collect data from your organization's Android devices so that you can monitor and troubleshoot the connectivity landscape of your Android user base. With this data, you can ensure that Android users have reliable, uninterrupted mobile connections to meet your business needs. You can efficiently target, troubleshoot, and resolve connectivity issues.

SysTrack's Android new performance data collection gives you access to two critical metrics:

  • Cellular Network Type

  • Cellular Signal Strength

Cellular Network Type

Cellular Network Type identifies the type of network to which the device is connected.

Understanding whether the Android device is on 4G, LTE, or other network types is valuable for anticipating and troubleshooting connectivity issues.

Android's Developer Documentation provides full details about Network Type.

The following table lists the constant values and network types for your reference.

Constant Value Network Name
0 unknown
5 EVDO revision 0
6 EVDO revision A
11 iDen (Legacy network type no longer being used starting in Android U)
12 EVDO revision B
13 LTE
14 eHRPD
15 HSPA+
16 GSM
19 Constant Value 19 is missing from Android Developer documentation.
20 NR (New Radio) 5G. This will only be returned for 5G SA. For 5G NSA, the network type will be NETWORK_TYPE_LTE.

Cellular Signal Strength

Cellular Signal Strength is measured in decibel-milliwatts (dBm).

TIP: Decibel-milliwatts is the standard unit of measure for expressing the absolute value of signal strength. It quantifies the power level of an electrical signal as compared to one milliwatt (mW).

Cellular Signal Strength provides a precise indication of the signal quality received by the Android device.

A higher dBm value generally indicates a stronger signal, which contributes to better call quality and data service performance.

With the dBM values that SysTrack collects for you, you can quickly assess signal strength in these ways:

  • Close to 0 dBm: A dBm reading that is close to 0 indicates a strong signal. For example, a signal strength of -30 dBm is considered excellent, and it is typically the strongest signal you will see in everyday use.

  • -50 to -79 dBm: This range is indicative of good to average signal strength. At this range, you can expect reliable phone calls and data services.

  • -80 to -99 dBm: This range is considered below average to poor. You might experience slower data rates and dropped calls.

  • -100 dBm or lower: Readings at or below -100 dBm are weak signals. Connectivity at this level is often unreliable, leading to poor call quality and slow data speeds.
