NEW DELHI: Hong Kong Telco (HKT), Global mobile Suppliers Association (GSA), and Huawei have jointly issued Indoor 5G Networks White Paper which explains the complexity of indoor 5G network deployment.
It discusses 5G indoor service network requirements, the evolution of existing network, and challenges in target network deployment, and recommends appropriate construction strategies.
The white paper points out that more than 80% of service usage on 4G mobile networks occurs indoors. The industry predicts that a greater number of mobile services will take place indoors as 5G spurs service diversity and extends business boundaries. As a result, says the white paper, indoor mobile networks in the 5G era will become essential to operators’ competitiveness.
Danny Dicks, Research Consultant at GSA, said: “Various services such as virtual reality (VR) and telemedicine will flourish in the 5G era. Indoor 5G digital networks will be essential to help ensure optimal user experience, efficient operation and maintenance (O&M), and intelligent operation. The industry urgently requires further research into the network requirements of indoor 5G services and network deployment strategies”.
The white paper discusses key requirements and performance indicators for indoor 5G target networks based on the features of the three major types of 5G services (enhanced mobile broadband, ultra-reliable low-latency communication and massive machine-type communication). The specific requirements of augmented reality (AR), VR, high-definition (HD) video, telemedicine, and smart manufacturing are elaborated.
Using test data and theoretical analysis, the white paper analyzes the challenges facing indoor 5G target network deployment. These include coverage, capacity expansion, reliability, O&M and operation. It then describes a series of deployment strategies in terms of architecture, Multiple-Input Multiple-output (MIMO), solution selection, capacity planning, network reliability, network O&M, and operation. These strategies provide guidance for indoor 5G network deployment, including:
Capacity: Build elastic capacity to flexibly meet service requirements.
Reliability: Use coverage, capacity and topological redundancy.
Deployment: Use E2E digital deployment to lay a foundation for network O&M.
Network O&M: Visualize network status for manageable and controllable indoor 5G networks.
Network operation: Make operation of indoor 5G networks intelligent by using a network operation platform between network and application layers.
Sheldon Yau, Senior Vice President of HKT Wireless Network Planning & Design, said: “Traditional passive indoor distributed systems cannot meet the requirements and challenges of indoor network upgrade and evolution in the 5G era. Only the innovative digital all-optical architecture can carry multiple systems and services to support more innovative services, faster data rates, flexible network expansion, efficient E2E operation, and smooth 5G evolution. This way, operators can effectively cope with the growing service types and service experience requirements in the 5G era”.
The white paper recommends indoor digital distributed base stations of 4T4R or above, with E2E digital integration. Dense, high-capacity networks with flexible capacity adjustment, and visualized O&M are also advised, and the white paper also proposes that intelligent operation of indoor 5G networks should be based on a network operation platform.
Liang Shiming, General Manager of Huawei’s Indoor Coverage Digitalization Domain remarked: “In the 5G era, indoor networks will be crucial to high-value mobile networks. Indoor coverage digitalization is the inevitable future of the industry. Huawei has proven capabilities and considerable experience in indoor network consulting, scenario-based solutions, digital products and integration, and industrial ecosystems. These put Huawei at the forefront of the indoor digital industry. In the next five years, Huawei will further increase its investment in the business solution development of indoor digital coverage. The company will also step up its cooperation with operators and industrial partners. The aim is to work with all parties to develop brand-new business models and industrial ecosystems, and usher in an era of 5G indoor digital coverage”.

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

5G now in 1947 cities across 72 countries
NEW DELHI: Viavi Solutions said that it has released new industry data revealing that the number of cities with 5G networks now stands at 1,947 globally. Despite the pandemic, 5G cities came online at a rate of nearly two per day, with the addition of 635 new 5G cities in 2021, according to the new VIAVI report “The State of 5G,” now in its sixth year.
By the end of January 2022, 72 countries had 5G networks in place, with the newest crop of 5G countries comprising Argentina, Bhutan, Kenya, Kazakhstan, Malaysia, Malta and Mauritius, which all came online in the second half of 2021. Europe, Middle East & Africa (EMEA) has overtaken Asia Pacific including Greater China (APAC) to become the region with the most 5G cities at 839. APAC has 689 5G cities and the Americas has 419.
Not surprisingly, the world’s two largest economies, the United States and China are the countries with the most 5G cities. China now has 356 5G cities and the United States has 296. The Philippines remained in the third spot globally with a total of 98 5G cities.
Currently, most 5G networks deployed are Non-Standalone (NSA) networks, meaning that 5G equipment is added to existing 4G network infrastructure. There are currently 24 Standalone (SA) 5G networks globally, meaning that they have been built using a new 5G core network. It is widely considered that many of the next-generation use cases and monetization models associated with 5G, beyond enhanced Mobile Broadband (eMBB) will only be possible when Standalone 5G networks built on new 5G core networks are in place.
The State of 5G also highlights the growing Open RAN ecosystem, combining mobile operators as well as software and infrastructure vendors, seeking to develop an open, virtualized Radio Access Network (RAN) with embedded Artificial Intelligence (AI) control. As of March 2022, 64 operators have publicly announced their participation in the development of Open RAN networks. This breaks down to 23 live deployments of Open RAN networks, 34 in the trial phase with a further seven operators that have publicly announced they are in the pre-trial phase.
“5G continued to expand, despite the headwinds of a global pandemic,” said Sameh Yamany, CTO, VIAVI Solutions. “What comes next in 5G is the reinforcement of networks. This will take a couple of forms. Firstly, we expect to see more Standalone 5G networks, which will deliver on much of the promise of 5G, both for the operator and for the wider ecosystem of users. And secondly, we expect to see Open RAN continue its rapid development and start to become a de facto standard. VIAVI will continue to play a central role in testing those new networks as they are built and expanded.”
