Anritsu Corporation (President Hirokazu Hashimoto) launches the following software options on November 6, 2017 to expand the LTE-Advanced Pro*5 (LTE-A Pro) evaluation functions of the company’s popular Signalling Tester MD8430A.
|- LTE DL 5 Carrier Aggregation*6 Option ||MD8430A-089|
|- LTE UL 3 Carrier Aggregation Option||MD8430A-045|
|- SCME Fading Option||MD8430A-053|
|- LTE Enhanced MTC Option||MD8430A-062|
|- Narrow Band IoT Option||MD8430A-063|
The Signalling Tester MD8430A is a base-station simulator supporting the LTE-A Pro standard and is used to configure a benchtop simulated network required for developing chipsets and data terminals. Additionally, configuring a simulated fading environment supports tests of LTE-A Pro effective communications speeds.
Adding these functions enables DL 5CA and UL 3CA IP data throughput tests of LTE-A Pro terminals connected to the MD8430A, as well as effective communications speed tests under an SCME fading environment, and Cat-M1 and NB-IOT protocol tests.
Anritsu plans to support further development of LTE-A Pro services by continuing to add new functions to the company’s MD8430A.
By widening the communications bandwidth using carrier aggregation and multi-antenna technologies, the LTE-A Pro standard supports data communications at speeds above 1 Gbps when the mobile terminal is moving fast. Additionally, 3GPP Release 13 defines new standards related to cellular IoT.
Introduction of LTE-A Pro technology in mobile communications markets requires evaluation of the following items.
- - Tests in environments with more component carriers (CCs) offering higher throughput
- - Protocol tests of Cat-M1 and NB-IoT terminals
- - Protocol tests using over-the-air channel modelling to evaluate LTE-A Pro terminal performance on live networks
Anritsu has expanded the functions of the Signalling Tester MD8430A by addition of these test functions.
The Signalling Tester MD8430A is a base-station simulator supporting the LTE-A Pro standard.
Using these newly developed functions supports evaluations for LTE-A Pro terminal performance under simulated DL 5CA, UL 3CA, and SCME fading environments, as well as Cat-M1 and NB-IoT simulated environments. Moreover, if the signals are within the same band, multiple base-station signals can be output from one Tx antenna, which cuts the need for multiple MD8430A test sets even when the number of Tx signals is increased by increasing the number of component carriers.
With excellent relative level accuracy*7 between antennas, the MD8430A fading function supports configuration of a high-reproducibility fading environment, which is difficult to achieve on a live network.
In addition, it also supports slow-clock tests*8 required for debugging at first stages of chipset development.
And combined use with the Rapid Test Designer (RTD) MX786201A software tool offering a GUI for easy creation of test sequences simplifies creation of test cases for base station simulation in a MIMO environment, permitting configuration of various test communications environments that are difficult to reproduce with a live base station. Last, with its built-in standalone fading functions, the MD8430A can be used to control fading in synchrony with mobile communications tests by controlling the fading function at the same interface.
*1 Cat-M1 (also called LTE-M)
Communications category for IoT devices that implements low power consumption by controlling the communications speed by limiting the wireless bandwidth to 1.4 MHz, expanding the intermittent Rx interval, and using a power-saving mode. The maximum downlink speed is 1 Mbps.
Like Cat-M1, standard for IoT using extremely narrow frequency band of 100 kHz to support low communications speed of about 100 kbps.
Extension of over-the-air channel model (SCM) defined by 3GPP TS25.996.
Phenomenon occurring at wireless communications, causing radio-wave level to strengthen and weaken due to interference resulting from radio waves arriving at different times. Fading can be caused by reflection of radio waves by obstructions on the ground as well as by interaction with the ionosphere, but in mobile communications it can also be caused by movement of the transmitting and receiving mobile.
*5 LTE-Advanced Pro
Higher-speed advance of Long Term Evolution (LTE) worldwide mobile communications standard supporting communications speeds of more than 3 Gbps when mobile terminal stationary or moving at low speeds, and 1 Gbps when moving at high speeds. Expansion of 4G standard forming basis of 5G.
*6 Carrier Aggregation (CA)
Technology for increasing communications speeds by securing wider bandwidth by using multiple LTE component carriers simultaneously. 5CA uses five LTE component carriers.
*7 Relative Level Accuracy
Performance index indicating which level difference is reliable in comparison of actual power difference between multiple signals and theoretical power difference, such as setting.
*8 Slow Clock Test
Test executed by setting lower reference clock frequency when generating baseband signal than frequency at finished product terminal.
