Huawei released its next-generation indoor mobile broadband (MBB) coverage solution LampSite 2.0 at the Mobile World Congress 2015. The company claims the solution provides a number of breakthrough features, including support for on-demand concurrence of triple frequencies, software-based bands, and dynamic capacity provisioning. It aims at providing users with excellent MBB experience anywhere anytime.
The key to operators’ shift from voice services to traffic-centered services lies in how they build high-quality networks and continuously improve service experience. It is not the same as in the days of voice services.
In the age of data, the better experience networks provide, the higher the quality of the contents from content providers is, which in return attracts subscribers to consume more mobile data and gives operators more opportunities to increase their revenues and profits in the MBB era.
Huawei cites the example of Zhengzhou Railway Station, the biggest transport hub in mainland China, which it says has seen significant improvement in MBB experience since it deployed Huawei’s LampSite solution. The solution helped unleash pent-up traffic demands in the transport hub, as shown by traffic increasing at a monthly rate of 340%. It has been estimated that operators can earn back the investment within just two years.
The essence of mobile traffic centered business lies in the service experience that networks can deliver. As Xu Zhijun, Huawei’ current rotating CEO, commented: “User experience is a driving force behind mobile broadband networks. It is also the number one force.”
Indoor coverage has always been an important element that boils down to user experience. In today’s MBB era, 80% or more of all network traffic is generated indoors, an important fact that puts indoor coverage at a prominent place.
As communications technology advances, the indoor coverage challenges that have been long troubling operators have not been eased; rather these challenges are now even more grave as multiband, multi-RAT deployment is more commonly practiced and site costs and maintenance expenditures reach new high levels, especially when considering that indoor coverage can no longer rely on outdoor macro networks.
To address these challenges, Huawei’s solution, as Xu pointed out, lies on technological innovations and indoor coverage digitization, increase the efficiency of indoor network building and maintenance, and improve the MBB service experience.
Huawei’s proposed digital-going indoor coverage solution includes:
In analogue indoor network architecture, signal source devices are centrally deployed and indoor networks use massive passive devices, creating strong interference and insufficient network capacity, making it difficult to expand
In digital indoor networks, radio frequency (RF) digital processing units are extended to network end nodes to significantly reduce interference and improve MIMO performance. Support for the software-defined band solution allows for on-demand deployment and capacity expansion.
Black-box management under the analog system architecture is replaced with visualized O&M on the entire indoor network, making implementation of node-level accurate fault and traffic monitoring at an even higher efficiency, a reality.
Digital service capability
Analogue indoor networks are mainly intended to satisfy coverage needs and provide voice services. Digital, indoor networks are added with superb capabilities to offer data services and meet demands for increased capacity. Through convergence with fixed networks and optimisation of local services, the service experience of enterprise applications can be improved remarkably.
In addition to retaining openness and scalability of digital network architecture, Huawei LampSite 2.0 goes further, to support a series of key features in a single RF unit, among which include software-defined bands, on-demand concurrence of triple frequencies, end node level cell splitting, and distributed MIMO.
It boasts on-demand capacity provisioning and cell edge resource co-ordination, indispensable functions to delivering greatly improved service experience in diversified indoor scenarios. This solution helps achieve accurate monitoring of all nodes on the entire network to guarantee network quality and service experience.
This solution also allows for first time success with network deployment and consistent evolution of the initially deployed networks to meet service requirements well into the future.
The mobile broadband advancement has opened up the mobile internet era, driving the transformation from enclosed to open development and pushing innovation across all industries and sectors. This trend, in return, has become a critical force, driving consistent improvement in the construction and business models of mobile communications.
Xu said: “Constructing indoor MBB network means continuous efforts to satisfy the demands from subscribers and operators. It also means proactive efforts to bring values to every participant in this process, including the property owners who provide site resources.”
Huawei said LampSite 2.0 offers strong voice and data communication capabilities. In addition, it supports interaction with Service Anchor, an enterprise service gateway, and represents strong openness of radio communication pipes.
This solution allows for cooperation with application development partners to offer value-added services, such as indoor navigation, statistical measurement of passenger flow, and pinpoint advertisement pushing.
The company concluded that with all these features, ‘LampSite 2.0 helps operators build high-ROI MBB networks that help implement their shift to traffic-centered business operation, provide various value-added services through telecommunication networks, and deliver an excellent service experience to subscribers’.
