BEIJING, Nov. 13, 2024 /PRNewswire/ — Just lately, Jiangxi Segment of China Telecom (China Telecom Jiangxi for trim) and Huawei collectively has constructed an F+T dual-layer top rate community for the high-speed railway. Cutting edge answers equivalent to 2.1 GHz 8T8R AAU and three.5 GHz wide-angle MetaAAU had been followed with the Prime-Pace Railway Great Enjoy and Prime-Pace Railway Devoted Community Enhancement options. Nearest the answer has been deployed, the efficiency of 5G networks is considerably advanced, permitting customers on trains to experience easy leisure services and products equivalent to reside streaming, HD movies, and Unused Calling, in addition to handy place of job services and products equivalent to far flung screams and far flung place of job.
China’s high-speed railway mileage has reached 40,000 km. Consistent with the 14th 5-Occasion Plan, the high-speed railway mileage will succeed in 50,000 km through 2025. Prime-speed railway situation is a standard high-value situation. In particular, each the penetration charge of 5G terminals and DOU are lofty. Scale down video packages and tone/video screams by means of WeChat are maximum usual ones. As well as, 5G community building on high-speed railways faces 4 demanding situations. First, the inter-site distance alongside high-speed railways is lengthy. 2d, the penetration loss within the high-speed railways is bigger than that of normal hurry railways. 3rd, when a teach strikes at a lofty hurry, the Doppler shifts building up, and the efficiency deteriorates. Fourth, the high-speed railway hurry is 300 km/h, and the cellular switching happens each 3 to 4 seconds on reasonable. Consequently, the staying length is trim, and consumer revel in is needful. How to succeed in the top rate protection of high-speed railways thru technological innovation is an impressive matter for China Telecom Jiangxi all the way through its long-term exploration and apply.
The Yingtan category of the Shanghai-Kunming Railway in Jiangxi Province has deployed the leading edge 2.1 GHz 8T8R AAU resolution. As an leading edge built-in AAU, the two.1 GHz 8T8R AAU options more than one antennas, built-in high-gain arrays, clever beams, and actual and speedy scanning. As well as, the two.1 GHz AAU stocks the similar antenna with the 1.8 GHz antennas at the reside community, preserve area and leases. The one-bit energy intake (energy intake/capability) of the two.1 GHz 8T8R is less than that of the 4T4R. Nearest the answer has been deployed, the onsite take a look at effects display that the protection is advanced through 5 dB in comparison with that of 4T4R. The typical downlink and uplink charges in all of the category building up through 21.6% and 50% respectively, and the downlink and uplink charges at edges building up through 82.6% and greater than 100%. Nearest 8T AAUs are deployed, the whole visitors quantity will increase through 89%; the 5G visitors distribution ratio reaches 52%, 13% upper than that of street divisions the place 4T is deployed. Along with higher protection, capability necessities are totally and clearly excepted.
Within the Nanchang category of the Shanghai-Kunming Railway, the leading edge 3.5 GHz wide-angle MetaAAU resolution has been impaired in a 7-km category to serve steady 3.5 GHz protection with an extended inter-site distance. Because the reasonable inter-site distance alongside the Shanghai-Kunming Railway is lengthy, the standard 3.5 GHz 8T resolution can’t serve steady protection. In high-speed railway situations, to obtain brandnew websites is frequently expensive. Due to this fact, China Telecom Jiangxi and Huawei have collectively added 3.5 GHz wide-angle MetaAAUs to the prevailing 2.1 GHz single-layer community. With the leading edge wide-angle MetaAAUs, steady protection within the street category with a median inter-site distance of 740 m and a most distance of a couple of km may also be learned. The two.1 GHz + 3.5 GHz service aggregation (CA) large-bandwidth resolution too can serve high-speed railway customers with top rate 5G revel in in services and products equivalent to far flung conferencing, HD movies, and gaming. Right through the economic deployment, the wide-angle MetaAAU has been deployed on the identical website with the two.1 GHz apparatus at the reside community to succeed in steady protection. Due to the answer, the deployment prices are a great deal lowered, and the deployment duration of the 5G top rate broadband community within the high-speed railway are shorter. Consistent with onsite assessments, 3.5 GHz wide-angle MetaAAU and a pair of.1 GHz CA can serve 100% protection alongside the high-speed railway. The typical charge has higher through 132%, taking a top place in festival. In particular, the typical downlink charge is 40% upper, and the brink charge is greater than two times. The three.5 GHz wide-angle MetaAAU too can successfully alleviate the high-load factor at the 2.1 GHz apparatus, making the user-perceived charge at the 2.1 GHz band higher through 93.7%. This additionally allows extra customers to benefit from the comfort introduced through 5G sly exit.
Nearest the Prime-Pace Railway Great Enjoy component is enabled, the sign frequency may also be proactively adjusted to offset the unfavourable have an effect on of frequency offset. As well as, it has resolved the Doppler shift factor took place within the steady protection of high-speed railways. Nearest the Prime-Pace Railway Great Enjoy component is enabled for the Jiangxi category of the Shanghai-Kunming Railway, the decision let go charge decreases through 75%; the consumer revel in of the downlink charge improves through 50%, and the visitors will increase through 20%.
Nearest the Prime-Pace Railway Devoted Community Enhancement component is enabled, the choice of inter-cell switches decreases. Moreover, the staying length is longer regardless of the common cellular switching of the high-speed teach, and the cellular revel in and capability are advanced as neatly. Nearest the Prime-Pace Railway Devoted Community Enhancement component is enabled for the Shanghai-Kunming Railway, the get admission to good fortune charge will increase to 99.2%, and each the revel in and capability building up through 50%. This resolves the disease of inauspicious get admission to and restricted capability in ultra-high-speed situations.
Going forward, China Telecom Jiangxi will proceed to cooperate with Huawei in 5G innovation, discover 5G community building necessities in varied situations, and create contributions to construction eminent 5G networks and facilitating virtual and clever transformation in Jiangxi Province.
