The actual value of your devices connection statistics is shown in the Lobaro platform under "Device Properties".
For "unstable" network coverage Lobaro can 't not guarantee the correct function of the cellular uplinks and battery lifes runtimes under all conditions. Please consider a different location for the particular device.

Geo Location Lookup
There are multiple ways to trace where a mobile device is.
In General the following information is required and transmitted in the device status packets:
- TAC → lac (dezimal), 0xcb20 = 52000
- Tracking Area Code (TAC) sometimes called Location Area Code (LAC)
- CI → cid (dezimal), 0x299A605 = 43623941
- Cell ID (CID / CID)
Here are some resources to use:
| Resource | Description | |
|---|---|---|
| Lookup Cells |
platform.eNodeB.towerID (based on CI ) var ci = parseInt("01DD4E02",16);

LTE network error codes
Newer firmware of Lobaro products report potential ESM (EPS Session Management) and EMM (EPS Mobility Management) errors in their status uploads.

For testing the coverage you can use our hardware with our USB Config Adapter and the Lobaro Maintenance Tool to observe the log during connection.
Or test yourself using a professional 3rd party network tester e.g. from ENQT.

NB-IoT / LTE-M Bands
Each Lobaro hardware only supports a subset of bands.
Operators might change bands without prior notice.
| Band | Uplink (TX) | Downlink (RX) | Bandwidth | Duplex-Mode | Used by |
| B3 | 1710-1785 MHz | 1805-1880MHz | 75 MHz | ||
B8 | 880 - 915 MHz | 925 - 960 MHz | 25 MHz | HD-FDD | Telekom |
B20 | 832 - 862 MHz | 791 - 821 MHz | 30 MHz | HD-FDD | Vodafone |
The NB-IoT Bands selected for Europe are B3 (1800 MHz), B8 (900 MHz) and B20 (800 MHz). B8 and B20 are supported by all Lobaro devices, B3 might be available on recent variants too.
