5G indoor dispensed Big MIMO doubles network capability in the Hangzhou Olympic Sports Center
China, Hangzhou – WEBWIRE – Wednesday, June 2, 2021
Lately, China Cell Zhejiang verified a pilot 5G network in the Hangzhou Olympic Sports Center. Operating on Huawei?s main products and choices, the network utilized 2.6 GHz and 4.9 GHz bands to give 5G protection in enclosed extremely-dense areas. As effectively as, 5G indoor dispensed Big MIMO used to be a great spotlight of the network.
The verification test utilized more than 400 5G devices to present stress checks with more than one networking choices keen intra-frequency, staggered-frequency, inter-frequency, and dispensed huge MIMO. In this course of, the cells had been under frightening capability ranges and 5G user behavior used to be additionally simulated to evaluate the efficiency of capability amplify, interference mitigation, and network redundancy.
The test results confirmed that the uplink capability used to be 50% increased than that got with cell splitting and the downlink and uplink interference is effectively curbed. This stage of efficiency suffices to fulfill the fleshy service requirements for messaging, Knowledge superhighway entry, video transfer, and broadcasting with ideal user skills. This would maybe well well simply be obligatory for network assurance in the ravishing stadiums for the 2022 Asia Video games.
The 80,000-seat Hangzhou Olympic Sports Center is an iconic lotus-petal modeled building, where the opening and closing ceremonies of the 2022 Asian Video games are anticipated to happen. China Cell is the educated accomplice for conversation services and products at this match.
And, as a fraction of the network assurance efforts, China Cell?s provincial branch of Zhejiang established a work group of workers with Huawei to stumble on contemporary bands, products, choices, parts, and approaches to amplify capability and fetch to the underside of rating interference in extremely-dense indoor areas. There would possibly be a huge assortment of 5G customers and various services and products occurring all over the games. With this in thoughts, the work group of workers serves to work out choices that can amplify network capability whereas minimizing the rate loss bobbing up from interference between cells. A steadiness between 5G capability and repair skills is obligatory to enable dedicated ravishing services and products by enhancing both user-perceived rate and network capability. This would maybe well well present necessary when building 5G networks in various dense scenarios as an skills in handing over superior user skills.
After thoroughly surveying the positioning and learning choices, China Cell Zhejiang adopted 2.6 GHz + 4.9 GHz dual-band networking for the mission. The 4.9 GHz band used to be ragged to deploy the capability layer on which Huawei?s indoor dispensed Big MIMO used to be deployed and 2:3 slot task used to be configured. This combination enabled a single cell to give an uplink rate of 1.2 Gbps. As effectively as, 16×16 extremely-narrow staunch beamforming used to be performed by leveraging the high-efficiency antennas to effectively isolate interference. Tests in the grandstand areas on both flooring 2 and 3 of the stadium confirmed that indoor dispensed Big MIMO would possibly maybe well well eradicate interference between cells, helping to amplify the uplink capability by 50% over 4T4R cells.
Indoor dispensed Big MIMO opens up a up to date course for exploring simply how mammoth indoor 5G networks can evolve. Incorporating the main applied sciences of outside 5G Big MIMO into indoor networks, dispensed Big MIMO supplies indoor networks with joint beamforming and multi-user MIMO (MU-MIMO) to make stronger both the 5G network capability and user skills. It eliminates the co-channel interference to purple meat up signal quality on multi-cell networks, providing a fixed high-journey, high-quality skills in most areas with 5G protection.
China Cell Zhejiang strives to present high-quality 5G networks to give customers with top class services and products and support the metropolis of Hangzhou host Asia Video games whereas supercharging it with ravishing services and products. Indoor dispensed Big MIMO would possibly maybe well well be the appropriate choice for sizable venues with a huge assortment of 5G mobile customers who’re attempting for a smarter spectating skills. This would maybe well well simply play a indispensable position in making the Hangzhou Olympic Sports Center stand out as a benchmark for ravishing stadiums at some level of China and beyond.
