VIAVI participates in O-RAN Plugfest across five countries
NEW DELHI: Viavi Solutions today announced, that the company successfully participated in a global O-RAN plugfest hosted by several Tier-1 communications service providers (CSPs) and the O-RAN ALLIANCE.
The plugfest involved a series of on-site demonstrations in multiple countries. VIAVI provided industry-leading 4G and 5G test and validation platforms to support the worldwide event, which demonstrated key Open Radio Access Network (O-RAN) use cases involving a number of network equipment manufacturers (NEMs) and system integrators, accelerating the commercialization of O-RAN and diversification of the RAN supply chain.
In a multi-vendor based O-RAN environment, ensuring interoperability will become the network operator’s principal concern. The VIAVI Test Suite for O-RAN Specifications offers comprehensive, integrated solutions to validate that all interfaces are working correctly – including RF, signaling and interoperability, timing and synchronization – and equipment is performing to specifications even under load and stress.
In the lab, the TM500 and TeraVM families deliver UE, O-RAN subsystem and core network simulation to enable conformance, interoperability and performance testing of both complete base station and core network testing as well as wraparound testing of individual O-RAN subsystems and core network elements.
In both the lab and the field, T-BERD/MTS-5800 validates critical synchronization parameters with necessary precision using its Timing Extension Module (TEM), delivering a highly stable reference signal for synchronizing test equipment and O-RAN components. CellAdvisor 5G characterizes and analyzes 4G and 5G RF signals. ONT-800 tests transport network performance up to 800G.
VIAVI supported the following plugfests:
· Berlin, Germany. This plugfest was hosted by Deutsche Telekom, with demonstrations of radio access equipment from Baicells, Benetel, Foxconn, QCT, Wind River, Wiwynn and other vendors. VIAVI provided the TM500 including UE emulation for performance testing and O-DU emulation for O-RU subsystem testing; TeraVM for core emulation and traffic generation; MTS-5800 for transport and synchronization test; and CellAdvisor 5G for RF signal analysis.
· Torino, Italy. This plugfest was hosted by TIM, with demonstrations of radio access equipment from Commscope, WNC, Wiwynn and other vendors. VIAVI provided the MTS-5800 for timing and synchronization.
· Madrid, Spain. This plugfest was hosted by a major Spanish service provider, with demonstrations of O-RAN x-haul (fronthaul and midhaul) transport with equipment from multiple vendors. VIAVI provided the MTS-5800 for timing and synchronization, and ONT-800 for multi-port transport test.
· Bengaluru, India. This plugfest was hosted by Airtel, with demonstrations of multi-vendor integration of O-RAN compliant radio access software and equipment from Altiostar, NEC, VVDN and Xilinx. The VIAVI TM500-C-5G 5G NR UE emulator and TM500 O-RU emulator were used for in-depth verification of the O-DU’s compliance to the WG4 open fronthaul (C/U/S planes) specification.
· Tokyo, Japan. This plugfest was hosted by Japanese service providers, with demonstrations of radio equipment from major O-DU/O-CU and O-RU vendors. VIAVI provided the TM500 for 5G NR UE emulation.
“As a champion of interoperability test methodologies, and the first company to introduce a comprehensive test suite for O-RAN specifications, VIAVI has worked closely with ecosystem partners and operators worldwide to help identify, isolate and resolve performance issues with disaggregated networks,” said Sameh Yamany, Chief Technology Officer, VIAVI.
“The successful results of the global O-RAN ALLIANCE plugfest represent a significant step forward in the advancement of multi-vendor O-RAN environments, which are essential to scaling and sustaining 5G networks,” he added.

NEW DELHI: The Union Cabinet chaired by the Prime Minister Narendra Modi has approved a Universal Service Obligation Fund (USOF) project for upgrading 2G mobile services to 4G at security sites in Left Wing Extremism (LWE) areas
The Project envisages upgrading2,343 left Wing Extremism Phase-I sites from 2G to 4G mobile services at an estimated cost of Rs.1,884.59 crore (Excluding taxes and levies). This includes O&M for five years. However, BSNL will maintain the sites for another five years at its own cost. The work will be awarded to BSNL because these sites belong to BSNL.
The Cabinet also approved funding of operations and maintenance cost of LWE Phase-I 2G sites by BSNL for an extended period beyond the contractual period of five years at an estimated cost of Rs.541.80 crore. The extension will be up to 12 months from the date of approval by the Cabinet or commissioning of 4G sites, whichever is earlier.
Government chose BSNL for a prestigious project to indigenous 4G telecom equipment so as to achieve self-reliance in the telecom gear segment to fulfil domestic market needs apart from exporting to other markets. This 4G equipment will be deployed in this project also.
The upgradation will enable better internet and data services in these LSW areas. It meets the requirements of Ministry of Home Affairs and the state governments. It shall also fulfil the communication needs of the security personnel deployed in these areas. The proposal is in line with the goal of providing mobile connectivity in rural areas. In addition, delivery of various e-governance services, banking services, tele-medicine; tele-education etc. through mobile broadband shall be possible in these areas.
NEW DELHI: Reliance Jio Infocomm Ltd. (Jio), India’s leading 4G and mobile broadband digital service provider, is constructing the largest international submarine cable system centered on India. Jio, in conjunction with several key global partners and world-class submarine cable supplier SubCom, is currently deploying two next generation cables to support the extraordinary growth in data demand across the region.
The India-Asia-Xpress (IAX) system connects India eastbound to Singapore and beyond, while the India-Europe-Xpress (IEX) system connects India westbound to the Middle East and Europe. The systems will seamlessly interconnect as well as connect to the world’s top interexchange points and content hubs for extension of service globally. IAX and IEX will enhance the ability for consumer and enterprise users to access content and cloud services in and out of India.
For the first time in the history of fiber optic submarine telecommunications, these systems place India at the center of the international network map, recognizing India’s increased importance, staggering growth, and the quantum shift in data use since the launch of Jio services in 2016.
These high capacity and high-speed systems will provide more than 200Tbps of capacity spanning over 16,000 kilometers. Employing open system technology and the latest wavelength switched RoADM/branching units ensures rapid upgrade deployment and the ultimate flexibility to add/drop waves across multiple locations.
“Jio is at the forefront of India’s explosive growth in digital services and data consumption. To meet the demands of Streaming Video, Remote Workforce, 5G, IoT, and beyond, Jio is taking a leadership role in the construction of the first of its kind, India-centric IAX and IEX subsea systems,” said Mathew Oommen, President, Reliance Jio.
“Implementing these critical initiatives in the shadow of a global pandemic is a challenge, but the ongoing pandemic has only accelerated the digital transformation and the necessity of high-performance global connectivity for the delivery of a richer experience to enterprises and consumers,” he added.
The IAX system connects India, the world’s fastest growing economy, to Asia Pacific markets with express connectivity from Mumbai and Chennai to Thailand, Malaysia, and Singapore. The IEX system extends India’s connectivity to Italy, landing in Savona, and additional landings in the Middle East and North Africa.
Apart from the seamless connection of the IAX and IEX sub-sea systems, the two systems are also connected to the Reliance Jio Global Fiber Network beyond Asia Pacific and Europe, connecting to both the east and west coast of the USA. IAX is expected to be ready for service mid-2023, while IEX will be ready for service in early 2024.
