The proliferation of smart phones and the mobile Internet results in massive data and network traffic growth. Network traffic is now converging on hotspot areas. 20% of sites in high-traffic areas carry 80% of the total network traffic. The traffic rates of sites in high-traffic areas are 6.5 times that of common sites. Presently, telcos' primary concern is to alleviate network traffic pressure and deliver excellent mobile user experience.
Coordinated indoor and outdoor coverage in built-up business districts, delivering a first-class network while enhancing user experience
A large number of large buildings, shopping malls, and commercial streets are often found clustered in crowded built-up business districts. Signals receptions in these buildings where many high-end subscribers reside are garbled and susceptible to interference and signals on the streets between these buildings are weak because of the building sizes.
Huawei adopts the industry-leading indoor/outdoor traffic analysis technology to address weak or excessive coverage, improving traffic absorption. This technology assesses hotspot coverage and implements coordinated indoor/outdoor coverage simulation and capacity planning to enable seamless coverage and improve traffic absorption.
Huawei provides diversified solutions and customized product portfolios based on network requirements. For example, micro cells can recover bottom-layer coverage holes in built-up business districts and the LampSite indoor coverage solution can improve traffic absorption in shopping malls.
Coordinated coverage of multiple networks for large-sized stadiums, carrying ultra-large traffic and improving telcos brand competitiveness
During a sporting event, large-sized stadiums have dense spectators and ultra-large traffic and signals in these stadiums are subjected to strong interference. For example, in a large-scale stadium designed to accommodate 70,000 spectators, tens of thousands of voice calls are made and some hundred GB of data traffic is generated during the event. Calls and data traffic peak at the beginning, during half-time, and at the end of the event. Dozens of cell sectors are used to process the ultra-large traffic. Any interference between these cell sectors may increase background noises and then cause network congestion.
With rich experience in serving over 400 major sporting events, Huawei provides dedicated solutions tailored to large-sized stadiums. These solutions can accurately estimate the capacity of an event and customize traffic bearer policies based on empirical traffic models for large-sized stadiums. These solutions can also interwork with the G/U/L/WLAN Offloading Solution to improve traffic absorption and enhancing resource utilization.
Based on experience accumulated from serving over ten well-known stadiums, Huawei provides a high-density cell sector solution designed to eliminate strong interference. This solution employs three-dimensional simulation to calibrate models, power, and layout positions of antennas, effectively controlling interference between cell sectors and maximizing the traffic capacity of each network.
Multi-telcos and multi-standard sharing in the metro, delivering high-speed service and achieving double win
The metro operates in narrow and enclosed underground areas which provide limited space for installing telcos devices. Usually, the metro is served by multiple telcos and thus has high requirements on interference control.
Based on technical indicators of different telcos, systems, and frequencies, Huawei provides a dedicated solution to detect and analyze interference sources in a multi-system environment and customize interference control measures. Besides, Huawei provides a modular SingleDAS solution with flexibly installed device modules to meet coverage requirements of different systems which can enable long distance transmission and reduces device space occupation, allowing end users to enjoy high-speed data services in express trains.
Flexibly scalable and large-capacity solutions for transport hubs, helping telcos win more high-end subscribers
With many large-scale buildings, functional areas, and roaming/high-end subscribers, a transport hub like an airport has high requirements on user experience and is a hotly contested spot for telcos to win more high-end subscribers.
Based on the analysis of airport subscriber behavior and traffic models, Huawei accurately determines the coverage and capacity requirements of different functional areas and then takes corresponding measures. For example, the parking apron area is fully covered with signals to ensure passengers' fast access to the network. This measure helps telcos win high-end international roaming subscribers. Based on current and future traffic requirements, Huawei appropriately plans cells for areas such as departure halls and VIP lounges that generate large traffic and also uses the remote capacity expansion feature of the LampSite indoor coverage solution to expand capacity on demand.
