ZTE unveiled its 5G RAN product portfolio for the 'Networks of the Future' back in February, just in time for the MWC that was unfortunately cancelled. One of the products was QCell.
ZTE’s QCell 5G indoor solution provides not only multi-mode, multi-frequency, ultrawide-bandwidth and large-capacity 4TR products, but also a more budget-friendly 2TR product that supports 300 MHz bandwidth, which is ideal for indoor RAN sharing and rapid introduction of 5G with lower deployment cost.
Yesterday, ZTE announced that along with the Jiangsu branch of China Telecom, they have deployed 5G 200 MHz Qcell 4T4R digital indoor distribution system in the indoor scenarios with high amounts of data traffic, such as shopping malls and subway stations, in Xuzhou, China. The system provides high-quality 5G indoor coverage, and accelerates future 5G indoor system deployment.
This commercial deployment has employed ZTE’s latest 5G Qcell ultra-wideband product series, which supports 200MHz continuous ultra-large bandwidth at 3.5 GHz frequency band, and 100MHz+100MHZ dual-carrier aggregation technology that doubles download rate.
For the time being, by virtue of China Telecom’s 100MHz 5G bandwidth, the single 5G user download rate has turned out to exceed 1 Gbps. In case of the activation of 200 MHz bandwidth in the future, the single 5G user download rate will exceed 2 Gbps, providing an excellent 5G experience.
Moving forward, ZTE will give full play to its technical and commercial advantages in the 5G field, continue to work closely with China Telecom to build high-quality 5G digital indoor networks, and develop 5G industrial applications, thereby facilitating the development of smart cities.
A partner feature on Mobile World Live provides a lot more technical details:
The ZTE QCell system consists of pRRU/pBridge/BBU (Baseband Unit) 3-level equipment. The 3-level efficient architecture supports the rapid cabling of CAT6a network cables or optical-electrical hybrid cables. It supports pBridge multi-level cascading, cell splitting and combination, and can rapidly respond to the operator’s requirements for the complex networking of different frequency bands and systems, rapid adjustment and flexible expansion of capacity and coverage.
The 300 MHz large bandwidth products with multi-mode and multi-frequency band enable the ZTE QCell solution the powerful network architecture integration capability, to meet the requirements of multi-operator’s co-building and sharing and have the compatibility and adaptability of global deployment. It not only supports the overlay networking of the existing DAS and 5G QCell, but also supports the feed-in of the GSM/UMTS DAS RF signals from different manufacturers in the existing network through the MAU, to protect the operator’s existing indoor distribution investment and introduce value-added services based on 5G coverage and precise positioning. QCell supports GSM/CDMA/UMTS/FDD LTE/TDD LTE/5G NR, which makes once deployment to implement the multi-operator/multi-band/multi-system indoor distribution system that achieves agile, long-term, co-construction, sharing, and lowest cost indoor distribution network, multi-system equipment and common management and maintenance. It only needs software upgrade for service expansion and network architecture evolution in the future so as to protect the investment in early-stage 5G indoor deployment and reduce the overall TCO cost from the perspective of long-term operation.
ZTE adopts innovative design of QCell products to reduce the cost and power consumption of equipment units. The pRRU transceiving channel not only supports high-performance 4T4R, but also supports low-cost 2T2R, further reducing the cost and power consumption. The pBridge enhanced product is designed to reduce the cost and power consumption after the electrical interface and optical interface are separated and the SoC solution is introduced. Moreover, the simplest BBU product is introduced to further reduce the QCell system networking cost.
The hierarchical QCell networking well matches diverse scenarios
Based on the analysis of the requirements for indoor distribution of operators, vertical industry enterprises, and large business owners, the indoor distribution scenarios can be divided into three types: capacity-sensitive scenario (type A), capacity and coverage balancing scenario (type B), and coverage-sensitive scenario (type C).
For the above three types of scenarios, ZTE provides hierarchical QCell networking solutions. Compared with the Benchmark QCell solution of 4T4R built-in antenna pRRU, ZTE provides a cost reduction solution of 2T2R built-in antenna pRRU and a low cost solution of 4T4R pRRU+ connected with external DAS antenna according to the scenario requirements, thus achieving the accurate network construction and saving operators’ investment. Evaluations based on the 40,000 square meters isolated indoor distribution scenario show: for scenario type B, the total main equipment investment is reduced by about 1/4; for scenario type C, through the external DAS antenna, the single-pRRU coverage area is greatly expanded and the overall investment is greatly reduced by about 1/2.
Extensive QCell Digital Smart Indoor Application, Making 5G Service Ubiquitous
The QCell digital intelligent indoor distribution system can be deployed for indoor and semi-indoor to achieve wireless coverage and service provision in high-value areas, such as large traffic hub, large stadiums, CBD and university campuses.
The large-scale traffic hub scenarios, such as airports, railway stations, and subway stations, have a large area and high population density, and are high-value areas for operators to guarantee both coverage and performance. The Wi-Fi system of most transportation hubs is often limited in capacity and cannot meet passengers’ requirements for future 4K/8K HD video. In Changsha Huanghua Airport, ZTE deployed the indoor high-capacity digital intelligent QCell solution with high-density networking and the first 3-carrier aggregation technology in China, to achieve the throughput of 8400Mbps for the airport. The solution supports 3,500 people simultaneously to enjoy HD video smoothly. At present, the QCell solution has been widely used in various metropolitan airports and railway hub stations, including Changsha Airport in Hunan, Xiaoshan Airport in Hangzhou, Nanjing South Station and Xining Railway Station, serving millions of passengers. Nanjing South Railway Station has a total building area of 45.8 million square meters, which is the largest railway station in Asia. After QCell is deployed, the SINR is increased by 13% and the throughput is increased by 91.8%.
The large stadiums, such as stadiums and exhibition halls, have a large number of users and a huge amount of data volume in a centralized manner. The QCell solution supports vertical partitioning to achieve seamless multi-layer coverage from the upper stands, the middle mezzanines to the bottom passages. At present, the QCell solution has been widely deployed in large stadiums such as Hangzhou Olympic Center, Hangzhou Expo Center, Suzhou International Expo Center, and Shenzhen New High-Tech Center. In August 2019, the ZTE 5G Smart Digital Indoor Division QCell solution covered many important sports venues including the Main Conference venue of the Red Lantern Stadium for the second National Youth Games (Shanxi), and made the Game the first “5G Games” in China. Through such technologies as MEC deployment and low delay coding, the ZTE 5G Smart stadium solution reduces the end-to-end live broadcast delay to 1 second, and provides audience with the excellent experience comparable to watching on the spot. In addition, ZTE also provides audience with brand-new experience in three 5G scenarios: immersive viewing experience from multi-angle live streaming, “Flexible Zooming” and “360-degree Free View” services. As an iconic application in the Game, the 5G Smart Stadium Solution provided an excellent demonstration for the live broadcast of sports events.
