SENTRY 4G/LTE Signal Analyzer and Cellular Logger

Siretta Ltd's SENTRY is a standalone remote cellular network analyzer that passively monitors the cellular environment that it is placed within and sends the data back to a cloud-based management portal (CloudSURVEY) where this can be viewed and analyzed. As well as passively observing the cellular environment, the SENTRY may optionally carry out performance tests on the cellular network to which it is registered, as well as measure parameters such as connection time, latency, and data transfer rates.

The SENTRY performs the measurements and tests from user requests on the cellular environment using an embedded STM32F405 Arm® Cortex®-M4 core CPU in conjunction with the cellular engine. The integrated GNSS receiver also determines the location where each cellular survey is carried out. The SENTRY runs the network tests and then immediately uploads the test results and location data via an encrypted connection to the CloudSURVEY portal. The CloudSURVEY portal can then display the detailed results of the cellular network testing.

Performance monitoring surveys additionally show cellular, TCP/IP, and socket registration times, uplink/downlink speeds, ping times, and comparative data with other cells of the same network. In areas where there is poor and/or intermittent cellular coverage, it is possible to configure the SENTRY to output its measurements on an RS232 serial port rather than post data to the CloudSURVEY portal (registration required).
