NB-IoT/eMTC Scanner

IoT Scanner covers the test and measurements for narrowband IoT (NB-IoT) and enhanced Machine-Type Communication (eMTC) specified by 3GPP for base stations. It is an integrated platform based on all-standard scanner and LPWAN analysis software. As a third-party test solution, IoT Scanner guaranteed the neutrality of test. IoT Scanner overcomes the disadvantages of conventional test solutions that does not support terminal handover. The instrument can measure and test cells deployed standalone, in-band or in guard band. Support switching to cell with strongest signal coverage in real time. Ultra-fast test speed and very high sensitivity make the instrument suitable for a variety of test environments, including road test.

Test NB-IoT and eMTC with one equipment

Conventional test solutions have several cons:
Do not support real-time terminal handover.
IoT manufacturers’ test solution are only for their own products. There is neutral solution that can test the actual coverage of IoT network from different manufacturers in contrast.
There is a lack of test solutions that supports both NB-IoT and eMTC measurement, cannot meet the carriers’ test requirements.

IoT SCANER Support both NB-IoT and eMTC signal demodulation. Report frequency of TOPN cell, PCI, RSRP, CINR and RSSI parameters. Measurement channels including PSS, SSS and RS. As compared to the previous solution, IoT Scanner supports real time terminal switching in NB-IoT test. Support the test of NB-IoT/eMTC network from all manufacturers. It can be used for manufacturers horizontal test and contrast.

Supporting software also has powerful features test plan can be freely defined, combined and showed in a variety of ways, such as track map, time domain graph, frequency domain graph, list, etc. Support data playback and parameter display, custom test report and automatically generate special test reports. Support the import and export of test data, test data can be generated into * .csv, *.kml and other formats. Instrument has built-in GPS module. The test results can be imported into third-party planning software to do network planning, and use with GoogleEarth for data analysis.

 Ultra-fast test speed and very high sensitivity

NB-IoT technology can enhance the uplink power spectral density, retransmission and codec technology to achieve more than 20dB coverage gain, compared to GSM. Therefore, achieve a coverage of more than 100 times the coverage of GSM, a wide and deep coverage. The detection level of the NB-IoT device should be less than -125dBm according to the LTE effective coverage level of -105dB. IoT SCANER provided by Transcom provide -130dBm sensitivity which will meet the needs of the test. Besides, data measurement and uploading of single frequency point can be completed in 3s to meet needs of various test environments, including road test.

 Support NB-IoT cell information measurement with three types of  depolyment

NB-IoT has three operation methods. The standalone operation is suitable for reuse the GSM band. Channel bandwidth of GSM is 200KHz. Just enough to embed the NB-IoT 180KHz bandwidth, and both sides can have a 10KHz guard band. The guard band operation uses resource blocks of unused 180 kHz bandwidth in the LTE edge guard band. In-band operation utilizes any resource blocks in the LTE carrier. With the NB-IoT / eMTC test instrument Transcom provided, you can automatically detect the three deployment methods, rapid measure information of cells with different deployment methods.

Case 1 – Yingtan City NB-IoT network coverage measurement

Yingtan city is the first one which deployed commercial NB-IoT network service in China.  In the year of 2017, invited by China Mobile, Transcom conducted a city-wide NB-IoT network coverage test in Yingtan City using its self-developed IoT scanner. This is the first DT assessment of commercial NB-IoT networks in China. The performance of the Transcom IoT scanner, including sensitivity, test dynamic range and test speed, was highly evaluated by China Mobile. The test results show that Yingtan City’s NB-IoT network coverage is excellent, as high as 91%. At the same time, Transcom IoT scanner became the first IoT scanner to participate in commercial IoT network testing in China.
