Sierra Wireless routers and gateways are pre-configured to send select data points to ALMS to populate the management system with the data needed to provide the best out-of-the-box user experience. The default data collected allows for the standard features of ALMS to work but may need to be augmented with additional data to address specific customer use cases. Please refer to How to create a dataset for more information on how to collect additional data.
The data consumption for AirLink routers and gateways will vary based on the device model, its embedded operating system and its configuration. Details provided are based on average values for an out-of-the-box device with its default configuration.
AirLink OS-based devices stream data to ALMS in a near real-time fashion based on your configuration. The default data supports the basic features of ALMS, and an additional telemetry data set can be easily enabled to populate data for Advanced Mobility Reporting.
Assuming an out-of-the-box configuration, the average data usage for an AirLink OS device is ~2.7 MB/day without Telemetry enabled and ~3.3 MB/day with Telemetry enabled. Data usage can be further reduced to ~400 KB/day by disabling both Telemetry and the Network Watchdog.
Actual data usage will vary considerably based on your application, configuration, and real-world network configuration. AirLink OS provides very granular controls for managing data communication on the router so we expect each customer’s experience will vary.
AirLink OS-based devices communicate with ALMS using the secure LWM2M protocol.
The datapoints in the following list are included in the default status report for AirLink OS routers (the exact number of datapoints depends on router SKU and hardware configuration):

System level information
ALEOS devices communicate with ALMS on a scheduled frequency A default status report is automatically created upon system first connection to AirVantage and scheduled at every system heartbeat. This frequency is by default once a day but is configurable from the Monitor activity.
Average data transfer per heartbeat is ~900 bytes
- upload: 512 bytes per heartbeat
- download: 382 bytes per heartbeat
Average data transfer per heartbeat + default status report is ~2 kBytes
- upload: 1,174 bytes per heartbeat
- download: 799 bytes per heartbeat
All data transferred between an AirLink device and ALMS using the LWM2M protocol is secured.
Note on MSCI: MSCI is a legacy communication protocol that Sierra Wireless has replaced with LWM2M. It is recommended that all users convert their older devices (where supported) to use LWM2M instead of MSCI.
Average data transfer per heartbeat is 5,8 kBytes
- upload: 1,649 bytes per heartbeat
- download: 4,281 bytes per heartbeat
Average data transfer per heartbeat + default status report is 11 kBytes
- upload: 3,270 bytes per heartbeat
- download: 8,030 bytes per heartbeat
Average data transfer per heartbeat is 1,4 kBytes
- upload: 936 bytes per heartbeat
- download: 504 bytes per heartbeat
Average data transfer per heartbeat + default status report is 3,11 kBytes
- upload: 1,987 bytes per heartbeat
- download: 1,027 bytes per heartbeat
