Huawei has released a 3D 18-sector solution to meet the large capacity requirements of ultra-high traffic scenarios. The solution allows for deployment of 18 sectors at a single site, which Huawei claims delivers 3.5 times the network capacity of traditional three-sector solutions.
The product has been tested and commercially deployed in countries including Bangladesh and Myanmar. It aims to provide users with an enhanced mobile broadband (MBB) experience in ultra-high traffic scenarios.
This 3D 18-sector solution, based on the reconstruction of original sites, increases network capacity to 3.5 times that of original three-sector sites. It uses six-beam, split antennas that split the original three sectors, both horizontally and vertically, into 18, increasing air interface and cell resources, and substantially improving network capacity.

The 3D 18-sector solution maximises single-site capabilities, thereby helping operators to handle ultra-high traffic in densely populated urban areas, at sporting events, during festivals, and at other large gatherings.
In these scenarios, massive numbers of mobile users gather together in a closed area, accessing the network at the same time. These spikes in network access temporarily increase the volume of data accessed on the network.
These enormous traffic bursts create tremendous strains on network stability and capacity. The 3D 18-sector solution helps to rapidly increase network capacity to meet capacity requirements in these ultra-high traffic scenarios, without adding any spectrum or site resources.
The 3D 18-sector solution is an important component of Huawei’s multi-sector solutions. To meet the different capacity requirements of various scenarios, Huawei has launched six-sector, nine-sector, hybrid three-sector and six-sector, and 3D 18-sector solutions, and supported joint planning and deployment of these solutions.
The six-sector solution improves network capacity by 1.7 times, helping operators increase UMTS network capacity in urban areas. To date, more than 100 mobile operators around the globe, at more than 100,000 sites, have used Huawei’s multi-sector solutions.
The nine-sector and 3D 18-sector solutions further improve single-site capacity. They are effective means of capacity expansion for the top 5% to 10% of hotspots in developing countries.
The nine-sector solution improves network capacity by 2.2 times and has been globally applied on 5 networks commercially, and over 10 trial networks. Commercial deployment of the 3D 18-sector solution further improves capacity for multi-sector solutions in terms of differentiated and efficient capacity expansion in different scenarios.
Mr. Yu Xiao, President of Huawei Wireless Network UMTS Product Line, said: "MBB user volume and service demands are growing rapidly. To help operators overcome the challenges presented by spectrum shortages, we have released successive multi-sector solutions to meet the capacity requirements of different scenarios. We are very happy that both field tests and commercial application of the latest 3D 18-sector solution in Bangladesh and Myanmar have produced satisfactory results."
Huawei will demonstrate more multi-sector business cases and innovative products and solutions at Mobile World Congress 2017 in Barcelona, Spain.
