 Huawei has produced a position report titled “5G Spectrum” that presents Huawei’s insights and recommendations on 5G spectrum policy. This report calls on the industry’s organizations and regulators to facilitate spectrum harmonization and ensure timely availability for early deployment and large-scale commercial use of 5G.
Huawei proposes a multilayer spectrum approach in consideration of the divergent requirements of 5G services and the different characteristics of related frequency bands. What Huawei calls the coverage and capacity layer relies on the 2–6-GHz range, e.g., the C band (3.3–4.2 GHz and 4.4–5 GHz), to deliver the best compromise between capacity and coverage.
This layer will emerge as the world’s first band for the much-anticipated 5G commercial deployment. What the company calls the coverage layer exploits the spectrum below 2 GHz (e.g., 700 MHz), providing wide-area and deep indoor coverage. Finally, the so-called super data layer relies on the spectrum above 6 GHz (e.g., 24.25–29.5 GHz and 37–43.5 GHz) to address specific use cases requiring extremely large capacity and high data rates.
The availability of spectrum resources in the 5G era needs governmental planning and allocation of contiguous spectrum. The C band is the key primary frequency band for the introduction of 5G by 2020. Each operator will need at least 100 MHz of contiguous channel bandwidth to support massive multiple-input, multiple-output (MIMO) to boost peak, average, and cell-edge throughput with affordable complexity.
The 5G New Radio (NR) system on the 3.3–3.8-GHz band is expected to be commercially ready in 2018. As the first step of 5G deployment, it is highly recommended that the 3.3–3.8-GHz region or a portion thereof be allocated as soon as practicable.
Rostelecom and Ericsson will carry out a 5G trial in Saint Petersburg, Russia, at the State Hermitage Museum, one of the world’s most prominent art repositories. The partners will deploy a 5G trial zone on the museum’s premises based on Ericsson’s latest 5G technology and will use a mix of VR, haptic technology, and robotics. The three parties involved made the announcement after signing a memorandum of understanding.
In the 5G trial’s preparation phase, which is scheduled for the first half of this year, Ericsson will deliver the full range of solutions required for the trial and provide expertise for the implementation and integration. The solutions include Ericsson Radio System, which is prepared for 5G implementation.
The network will operate in the 3.5-GHz frequency band and support long-term evolution (LTE) and LTE Advanced devices. The project is well aligned with Rostelecom’s strategy to become a provider of high-quality, integrated digital services for a comfortable life and effective business operations.
The deployment of 5G technologies is part of Russia’s Digital Economy Program, which aims to create a digital ecosystem where businesses, academic communities, government, and social institutions collaborate in a truly efficient way.
