Vertiv, together with technology analyst firm 451 Research, has released the report on the state of 5G, “Telco Study Reveals Industry Hopes and Fears: From Energy Costs to Edge Computing Transformation.” The report captures the results of an in-depth survey of more than 100 global telecom decision makers with visibility into 5G and edge strategies and plans. The research covers 5G deployment plans, services supported by early deployments, and the most important technical enablers for 5G success.
Survey participants were overwhelmingly optimistic about the 5G business outlook and are moving forward aggressively with deployment plans. Twelve percent of operators expect to roll out 5G services in 2019, and an additional 86% expect to be delivering 5G services by 2021.
According to the survey, those initial services will be focused on supporting existing data services (96%) and new consumer services (36%). About one-third of respondents (32%) expect to support existing enterprise services with 18% saying they expect to deliver new enterprise services.
As networks continue to evolve and coverage expands, 5G itself will become a key enabler of emerging edge use cases that require high-bandwidth, low latency data transmission, such as virtual and augmented reality, digital healthcare, and smart homes, buildings, factories and cities.
However, illustrating the scale of the challenge, the majority of respondents (68%) do not expect to achieve total 5G coverage until 2028 or later. Twenty-eight percent expect to have total coverage by 2027 while only 4% expect to have total coverage by 2025.
“While telcos recognize the opportunity 5G presents, they also understand the network transformation required to support 5G services,” said Martin Olsen, vice president of global edge and integrated solutions at Vertiv. “This report brings clarity to the challenges they face and reinforces the role innovative, energy-efficient network infrastructure will play in enabling 5G to realize its potential.”
To support 5G services, telcos are ramping up the deployment of multi-access edge computing (MEC) sites, which bring the capabilities of the cloud directly to the radio access network. Thirty-seven percent of respondents said they are already deploying MEC infrastructure ahead of 5G deployments while an additional 47% intend to deploy MECs.
As these new computing locations supporting 5G come online, the ability to remotely monitor and manage increasingly dense networks becomes more critical to maintaining profitability. In the area of remote management, data center infrastructure management (DCIM) was identified as the most important enabler (55%), followed by energy management (49%). Remote management will be critical, as the report suggests the network densification required for 5G could require operators to double the number of radio access locations around the globe in the next 10-15 years.
The survey also asked respondents to identify their plans for dealing with energy issues today and five years in the future when large portions of the network will be supporting 5G, which 94% of participants expect to increase network energy consumption. Among the key findings:
Reducing AC to DC conversions will continue to be an area of emphasis, with 79% of respondents saying this is a focus today and 85% saying it will be a focus five years from now.
New cooling techniques will see the biggest jump in adoption over the next five years. Currently being used by 43% of telcos worldwide, this number is expected to increase to 73% in five years.
Upgrades from VRLA to lithium-ion batteries also show significant growth. Currently, 66% of telcos are upgrading their batteries. Five years from now, that number is projected to jump to 81%.
“5G represents the most impactful and difficult network upgrade ever faced by the telecom industry,” said Brian Partridge, research vice president for 451 Research. “In general, the industry recognizes the scale of this challenge and the need for enabling technologies and services to help it maintain profitability by more efficiently managing increasingly distributed networks and mitigating the impact of higher energy costs.”
