The role of fiber, testing in 5G

When we talk about 5G or any other wireless technology, our brain focuses on the wireless aspect of the technology. In reality, only the last hop of the wireless network is actually wireless.

Most of the data communication happens over a wired network. RF spectrums being such a precious resource, mobile operators try their best to offload their traffic to a wired network as soon as possible.

5G use cases such as gigabytes of data throughput, augmented reality, massive machine type communication, and connected cars etc. will have significant impact on the capacity of the wired network supporting the wireless infrastructure, not to mention a significant cost.

The fixed parts of the overall wireless network are still classified as core, metro and access. Core and metro are normally interconnected through optical transport. However, the access domain uses a heterogeneous set of transport technologies including fiber, DSL, G.fast, coax, micro wave, and mm-wave. Basically, any cost-effective technology or a combination of it that can deliver data at a minimum required QoS.

As we move forward in the 5G evolution, fiber deployment will grow exponentially (for example), and to ensure networks are delivering the promise of 5G, it is essential that service providers act to validate all the components of the network every step of the way.

Seeing a green light on the baseband unit or remote radio does not guarantee system performance; signal levels could be marginal or on threshold and may not survive environmental effects. Having dust caps on fiber connectors does not guarantee a connection is clean; small particles can still migrate onto the surface and contamination can occur during build or staging. A shortage of fiber experts and the skill gap with installers is another challenge the cellular industry is facing.

During the installation and commissioning phase of the wireless network, the following tests should be performed at minimum: fiber inspection and connectivity test, power/optical return loss, xWDM validation, fronthaul and backhaul validation, and coax sweep test. Failure to perform these tests can significantly degrade network performance, negatively impact CapEx and Opex and cause customer churn. VIAVI has been working with service providers to help them, through the complex journey to 5G.

Narendra Modi inaugurates India’s first 5G testbed; says aims to roll out 6G end of decade

Published

NEW DELHI: India is targeting the rollout of 6G telecom network, which will provide ultra high speed internet connectivity, by the end of the decade, Prime Minister Narendra Modi said on Tuesday.

India currently has 3G and 4G telecom networks and companies are gearing up to launch 5G over the next few months.

Speaking at the silver jubilee event of telecom sector regulator TRAI here, he said it is estimated that the 5G network rollout will add USD 450 billion to the Indian economy.

“This is not just increasing internet speed but also the pace of development and creating jobs,” he said, adding the 5G technology will bring positive change in governance of the country, ease of living and ease of doing business.

It will boost growth in agriculture, health, education, infrastructure and logistics, he said.

Connectivity, Modi said, will decide the progress of the country in the 21st century and so modern day infrastructure needs to be rolled out.

According to the prime minister, a task force has started work on rolling out 6G network by the end of the decade.

Taking potshots at the previous Congress-led UPA government, Modi said the 2G era was symbolic of policy paralysis and corruption.

The country, under his government, has moved transparently to 4G and is now going to 5G.

Teledensity and internet users are fast expanding, he said, adding that mobile manufacturing units in India have expanded from 2 to over 200 and the country is now the world’s biggest mobile manufacturing hub.

The prime minister also said that his government has encouraged healthy competition that has led to India having one of the cheapest telecom data charges in the world.

Indigenous 5G test bed in telecom sector is an important step in India’s self-reliance, he added.

PM Modi virtually inaugurates India’s first 5G testbed costing Rs 220 crore

Prime Minister Narendra Modi on Tuesday inaugurated the country’s first 5G testbed to enable startups and industry players to test and validate their products locally and reduce dependence on foreign facilities.

The testbed has been set up at a cost of around Rs 220 crore. Speaking at the silver jubilee celebrations of the Telecom Regulatory Authority of India (Trai), the Prime Minister said the 5G testbed is an important step for self-reliance in the direction of critical and modern technologies.

“I invite youth friends, researchers and companies to utilise the testing facility for making 5G technology,” Modi said.

The 5G testbed has been developed as a multi-institute collaborative project by eight institutes led by IIT Madras.

In the absence of a 5G testbed, startups and other industry players were required to go abroad to test and validate their products for installation in a 5G network.

The other institutes that participated in the project are IIT Delhi, IIT Hyderabad, IIT Bombay, IIT Kanpur, IISc Bangalore, Society for Applied Microwave Electronics Engineering & Research (SAMEER) and Centre of Excellence in Wireless Technology (CEWiT).

The testbed facility will be available at 5 different locations.

3 Scandinavia expands 5G footprint with Enea’s policy control technology

Published

NEW DELHI: 3 Scandinavia, a leading provider of voice and broadband services, has deployed Enea’s 5G policy control solution as it continues to expand its 5G footprint. The solution will allow 3 Scandinavia to effectively launch, manage, and monetize new services in Sweden and Denmark.

Enea’s powerful policy platform will allow the Nordic network provider to differentiate services and ensure that all subscribers benefit from a consistent quality of service to match their chosen pricing plans.

Enea’s policy management platform, a fully virtualized, multi-vendor solution, has provided 4G policy control functionality for 3 Scandinavia since 2008. As the operator looked to scale its capabilities with virtualized architecture, it turned to Enea for 5G policy control. Enea’s platform delivers robust connectivity and cost-effective service management while bringing operational agility through its tight integration with provisioning systems. It is also vendor agnostic, which means that the operator has the freedom to work with any network access provider and can configure new types of 4G and 5G services in a matter of minutes.

“We are always striving to offer innovative services that appeal to our growing base of subscribers,” says Per Stigenberg, CTO at 3 Scandinavia. “In today’s world of stream-based entertainment and hybrid working, this means taking full advantage of everything 5G has to offer. Enea has demonstrated a thorough understanding of our needs and with their flexible product approach we are now able to deliver a next-generation connectivity experience for all our subscribers in Sweden and Denmark”

The solution from Enea also enables the operator to effectively manage several of its virtual Policy Control Functions (PCFs) across two physical locations in Scandinavia. With Enea’s platform deployed, 3 Scandinavia can efficiently support fully redundant 5G voice and data services throughout both Sweden and Denmark, allowing the operator to seamlessly control policies as subscribers move between 4G and 5G, and across their networks.

“Policy control is very much the brains of the operation when it comes to providing cellular services to millions of subscribers,” says Jonas Jacobsson, Senior Vice President of Service Provider Sales at Enea. “Without it, there is simply no way to differentiate service in terms of data allowance or speed, particularly with 5G where these configurations become even more granular.”

A report from Deloitte found that the number of 5G subscribers in Scandinavia has more than doubled in the past two years. As networks grow, policy plays a critical role to help operators scale and monetize 5G.
