Monday 24 February 14

The proliferation of smart phones and the mobile Internet results in massive data and network traffic growth. Total mobile data traffic is widely forecasted to exceed 10,000 PB per month in 2015, with an expected annual compound growth rate of over 100% from 2011 to 2015. 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.

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.


Based on a profound understanding of hotspot areas and rich industry experience, Huawei provides the HetNet Integration Solution to help telcos improve user experience and increase revenue efficiently.
 

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 dynamically balance traffic between GUL base stations and Wi-Fi hotspots, improving 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.
 

Dedicated solutions for school/corporate campuses with multi-functional areas, enabling resource sharing and improving resource utilization

A school/corporate campus has many indoor functional areas such as teaching buildings, dining halls, and dormitories as well as outdoor functional areas such as playgrounds and campus roads. Traffic generated in these different functional areas is extremely uneven.
Huawei provides dedicated solutions to analyze possible traffic generated in these functional areas at different time based on their service requirements, and then customizes a capacity model adapting to traffic changes. In these solutions, a 3-Layer network with coordinated macro cells, micro cells, and indoor distributed systems is adopted to achieve seamless coverage and multiple remote radio units (RRUs) are used to cover one cell to enable network capacity sharing and improve resource utilization and the ROI.
 

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 dynamically expand capacity on demand.
 

To date, Huawei has provided indoor coverage services to 115 telcos in 64 countries all over the world and set up over 26,000 hotspot networks. Huawei's indoor coverage solutions are adopted in many landmarks such as the United Nations Headquarters, Mall of the Emirates, Brazil World Cup stadium, Baku Crystal Hall, Paris metro, and Zurich Airport.
