ETS-Lindgren, Anritsu announce 5G NR stand-alone mode and carrier aggregation test support

Published

on

NEW DELHI: ETS-Lindgren and Anritsu Company continue years of successful collaboration on 5G test capability with verification of stand-alone (SA), dual-connection (EN-DC), and several carrier aggregation combinations within ETS-Lindgren’s EMQuest EMQ-100 Antenna Measurement Software using Anritsu’s Radio Communication Test Station MT8000A.

The additional 5G connection modes and band scenarios allow the construction of tests mimicking network settings particular to an individual wireless carrier. As smartphones, modules, and base stations utilizing 5G transceivers continue to expand to new applications and form factors, over-the-air (OTA) testing provides confirmation that the device will perform well in the intended network and use case.

“Adapting the link settings to match the dozens of 5G network configurations found worldwide was an important milestone,” said James Young, Director, Business Development with ETS-Lindgren.

“The device manufacturers gain critical insight on antenna and radio performance from these radiated tests, as all the discrete systems come together in the final form. EMQuest EMQ-100 and MT8000A now link to commercially available 5G devices driven by different chipsets in SA mode. This collaborative work between ETS-Lindgren and Anritsu is critical for our test lab customer base who rely on the test system to handle whatever link settings are available on the chipset,” he added.

Anritsu Wireless Market Development Manager Keyvan Yasami added, “Our collaboration with ETS-Lindgren addresses SA and carrier aggregation testing needs to create a solution that helps test labs and OEMs keep current with the expanding requirements of global operators, regulatory bodies, and industry standards issued by CTIA and 3GPP. We will continue to work with fellow market leaders such as ETS-Lindgren to ensure maximum utilization of 5G test equipment and chambers.”

ETS-Lindgren’s EMQuest EMQ-100 offers a wide range of fully parameterized test methods for measuring basic antenna performance metrics, as well as testing both radiated and conducted performance of various wireless devices. Flexible in its design, the EMQuest EMQ-100 can be used to analyze antennas in SA applications, or to test an embedded antenna system and radio module against any of the industry standard OTA radiated performance test requirements.

Anritsu’s MT8000A test platform supports the latest 5G technologies, including wideband signal processing and beamforming required by 5G NR enhanced mobile broadband (eMBB). The MT8000A all-in-one platform supports FR1 and mmWave band (FR2) signaling RF tests covering 400 MHz to 7.125 GHz, as well as the 28 GHz and 39 GHz 5G NR bands.

The MT8000A supports both non-stand-alone (NSA) and SA modes and is the first 5G NR test platform to support 5G NR channel models implemented via digital baseband fading. It can also be paired with the LTE-A Radio Communication Analyzer MT8821C to provide a natural upgrade path to 5G for existing LTE customers.

Telecom Service Providers to start 5G trials in different locations across India

Published

on

NEW DELHI: The Department of Telecommunications (DoT), Government of India, approved today, permissions to Telecom Service Providers (TSPs) for conducting trials for use and applications of 5G technology. The applicant TSPs include Bharti Airtel Ltd., Reliance JioInfocomm Ltd., Vodafone Idea Ltd. and MTNL.

These TSPs have tied up with original equipment manufacturers and technology providers which are Ericsson, Nokia, Samsung and C-DOT. In addition, Reliance JioInfocomm Ltd. will also be conducting trials using its own indigenous technology.

The permissions have been given by DoT as per the priorities and technology partners identified by TSPs themselves. The experimental spectrum is being given in various bands which include the mid-band (3.2 GHz to 3.67 GHz), millimeter wave band (24.25 GHz to 28.5 GHz) and in Sub-Gigahertz band (700 GHz). TSPs will also be permitted to use their existing spectrum owned by them (800 MHz, 900 MHz, 1800 MHz and 2500 MHz) for conduct of 5G trials.

The duration of the trials, at present, is for a period of 6 months. This includes a time period of 2 months for procurement and setting up of the equipment.

The permission letters specify that each TSP will have to conduct trials in rural and semi-urban settings also in addition to urban settings so that the benefit of 5G Technology proliferates across the country and is not confined only tourban areas.

The TSPs are encouraged to conduct trials using 5Gi technology in addition to the already known 5G Technology. It will be recalled that International Telecommunications Union (ITU) has also approved the 5Gi technology, which was advocated by India, as it facilitates much larger reach of the 5G towers and Radio networks.The 5Gi technology has been developed by IIT Madras, Centre of Excellence in Wireless Technology (CEWiT) and IIT Hyderabad.

The objectives of conducting 5G trials include testing 5G spectrum propagation characteristics especially in the Indian context; model tuning and evaluation of chosen equipment andvendors; testing of indigenous technology; testing of applications (such as tele-medicine, tele-education, augmented/ virtual reality, drone-based agricultural monitoring, etc.);and to test 5G phones and devices.

5G technology is expected to deliver improved user experience in terms of data download rates (expected to be 10 times that of 4G), up to three times greater spectrum efficiency, and ultra low latency to enable Industry 4.0. Applications are across a wide range of sectors such as agriculture, education, health, transport, traffic management, smart cities, smart homes, and multiple applications of IOT (Internet of Things).

DoT has specified that the trials will be isolated and not connected with the existing networks of TSPs. Trials will be on non-commercial basis.

The data generated during the trials shall be stored in India. TSPs are also expected to facilitate the testing of the indigenously developed use cases and equipment as part of the trials. One hundred applications/ use cases selected by DoT after conducting the recent Hackathon on 5G applications can also be facilitated in these trials.
