The Groundbreaking Technology of 5G from Huawei Can Lead the Future
Huawei recently unveiled a full range of end-to-end (E2E) 3GPP – compliant 5G product solutions at the World Mobile World Congress (MWC) held in Barcelona, Spain. The products were presented by Yang Chaobin, President of Huawei 5G Product Line. Huawei covers the core network, the bearer network, base station, and terminals. Entirely based on 3GPP standards, Huawei’s 5G product solutions come with full range, full scenario, and all-cloud being the defining characteristics. The featured IT products are also the only available options within the industry to provide 5G E2E capabilities.
Huawei’s newly released full range of 5G product solutions support millimetre wave (mmWave), C-band, and all Sub-3 GHz frequency bands. These products also cover all site forms including tower sites, pole sites, and small cells. The first wave of 5G deployment will take place in buildings and densely populated urban areas. Diverse site forms are therefore required to accommodate the needs of complex deployment scenarios, offering continuous coverage and fulfill capacity requirements of indoor and outdoor hotspots.
New Huawei AAUs
Huawei also launched the C-band 64T64R and 32T32R Massive MIMO AAUs to deliver ubiquitous Gbps experience. These AAU’s:
- support 200 MHz large bandwidth and 3D beamforming to cover buildings
- offer uniform coverage
- meet the demands of various other scenarios.
Coverage can be flexibly adjusted to optimise the experience for users at the near points and far points, and generate a 20 or 30 times increase in network capacity. mmWave products are suited to supporting 1 GHz bandwidth. The equivalent isotropically radiated power (EIRP) of Antenna ports reaches 65 dBm, ranking first within the industry.
Huawei Wireless: Integrated, Compact & Lightweight
Huawei’s wireless products boast an integrated, compact, and lightweight design. They also considerably relax the requirements on the antenna installation platform while reducing engineering complexity. All products support various scenarios in a centralised radio access network (C-RAN) and distribute radio access network (D-RAN) deployment mode. The optical interface speed is less than 25 Gbps, which is ideal for large-scale 5G deployment. Also, the newly released compact 5G Massive MIMO products working in the C-band and mmWave allow for implementation on street lamp poles to fill coverage holes and boost hotspot capacity. The 5G LampSite is backwards-compatible with 4G. Existing CAT6A network cables or fibre optic cables can be used to achieve indoor 4G and 5G co-deployment with zero cable adjustment or site addition. Huawei also launched BBU5900 and CBU5900 to suit distributed and centralised sites, respectively.
BBU5900 is the most highly integrated site solution currently available in the industry. It supports all RATs and all frequency bands, and offers 50 Gbps backhaul capability to meet 5G services’ long-term development needs. CBU5900 features the centralised deployment of a large number of baseband units to support the C-RAN architecture. Using CBU5900 helps to:
- simplify remote sites
- reduce the demands for air-conditioned equipment rooms
- contribute to quick satellite clock synchronisation across the entire network
This approach also lowers future site maintenance and expansion costs and reduces the number of site visits during IT maintenance and installation. Also, it will boost the performance of the entire network via large-scale close coordination.
5G Bearer Networks: Diverse Active and Passive Solutions
5G networks feature 10 GE transmission capability to the site and 50 GE/100 GE transmission capability from fibre optic cables. This access rings, fulfilling the ultra-large capacity requirements of multiple 5G eMBB services. In a C-RAN scenario, the transmission speed between the centralised equipment room and the site must reach 100 Gbps. Such conditions pose enormous challenges to operators’ mobile bearer networks. The current release includes a range of Huawei 5G bearer product combinations that suit various scenarios, use different media, and take many distinct forms.
In backhaul scenarios, 5G microwave series products can offer 10 Gbps high data rate and 25 µs low latency when traditional microwave frequency bands are used. Meanwhile, 50 GE/100 GE adaptive slicing routers support smooth evolution from 10 GE to 50 GE and 100 GE. This allows operators to implement on-demand deployment. The effective FO OTN fronthaul solution supports up to 15 channels of service access, hitless switching, and integrated access for multiple services. The Centralized WDM fronthaul solution uses innovative colourless optical modules to simplify site delivery and operation and maintenance (O&M). Huawei X-Haul 5G bearer solution supports multiple technologies, such as IP, OTN, and microwave. The aim is to help operators resolve bearer network issues in large-scale 5G deployment.
5G Core Networks: All-industry Digitalisation Through All-cloud Architecture, on-demand Deployment, and Smooth Evolution
Based on the all-cloud architecture, Huawei’s 5G core network solution uses microservice-centric architecture (MCA) to simultaneously support RAT’s and realise a smooth evolution from non-standalone (NSA) to standalone (SA). Meanwhile, unlike the traditional network architecture, Huawei’s 5G all-cloud core network uses a distributed architecture based on the control plane and user plane separation (CUPS) to help operators deploy the control plane at the central DC and flexibly deploy the user plane according to the service scenarios.
For example, for eMBB services such as augmented reality (AR)/virtual reality (VR) and HD IPTV over WTTx, the user plane can be deployed at the network edge. This minimises the roundabout traffic on the backbone network, achieves ultra-low latency, and eradicates congestion. The all-cloud 5G core network is also the basis of network slicing. As the new business model of the 5G era, network slice will help operators to provide various services via a single network. Because of this, a business transformation from the mass market to the vertical industry market can happen.
5G Terminal: Small Sized Commercial Product With Low Consumption to Provide Fibre-like Access Experience of Wireless Home Broadband
During the MWC 2018, Huawei also released a range of 5G terminals. 5G customer premise equipment (CPE) which is compact in size, low in power consumption, and highly portable is developed based on the 3GPP standards and chipset architecture. As the smallest 5G commercial terminal in the world, it supports C-band and mmWave. In Seoul and Canada, there has been the world’s first wave of 5G subscribers who use Huawei’s commercial 5G terminals. Based on 3.5 GHz and mmWave, users can enjoy a fibre-like experience of wireless home broadband services with the rate exceeding 2 Gbps.
Huawei Smart Phones
Also, Huawei will launch 5G smartphones in 2019. The year 2018 will be the first year that marks the beginning of the 5G era. Using a full range of leading and mature 5G E2E full-scenario product solutions, Huawei has realised the continuous deployment of 5G sites in more than ten countries. These include China, Korea, Canada, Germany, UK, and Italy. In typical densely-populated urban areas, these product solutions have provided ubiquitous Gbps-level access rate. There are also hundreds of Mbps of indoor access experience and over 20 Gbps cell capacity. The countdown has begun for large-scale 5G commercial launch worldwide. Huawei is making the most comprehensive preparations.
