The Evolution of Service Assurance (RCR Wireless)

[Missing text /library/documenttype/WEB for zh]

Service assurance has been an ongoing struggle for wireless carriers as they look to balance their spectrum and network assets with growing consumer demand. Advances in software have become the latest tools use by mobile operators, including the move towards virtualization in order to become more agile in handling service assurance demands. This webinar will look to provide insight into the companies providing such software support and how operators are tapping into that help to better manage their networks and services delivered to customers.

HetNet Series: Small Cells and Wi-Fi (Spanish by TeleSemana)

[Missing text /library/documenttype/WEB for zh]

Operators are looking at the deployment of small cells and Wi-Fi hotspots in dense urban areas as means to deal with congestion. However, an urban area presents many deployment challenges for this new infrastructure and thus operators will face very different scenarios and many times the experience in one neighborhood may not help to deploy the infrastructure in the next one.

Shedding Light into NFV Performance

[Missing text /library/documenttype/WEB for zh]

The general consensus is that network functions virtualization (NFV) will reduce operational and capital expenditures (OPEX and CAPEX) by leveraging commodity hardware and induce operational efficiency by providing flexible and automated service delivery leading to faster time to market. This will not come without major challenges in terms of availability, reliability and performance but most importantly it will bring about a paradigm shift of monitoring individual or small groups of network elements and resources to systematic end-to-end service and resource monitoring.

Wi-Fi: Leveraging Unlicensed Spectrum to Offload Cellular Networks

[Missing text /library/documenttype/WEB for zh]

The low cost and the use of unlicensed spectrum has made carrier-grade Wi-Fi of strategic importance to many mobile network operators (MNOs).

MNOs view it as a means to expand service coverage with very low CAPEX and OPEX. In this context, it is imperative to understand the various challenges of this integration and of ensuring optimal performance to deliver seamless mobility and enhanced quality of experience to subscribers.

Mobile Data Traffic: Taming the Beast

[Missing text /library/documenttype/WEB for zh]

Thanks to the seemingly insatiable appetite for data on the move, mobile data traffic is expected to continue growing at a phenomenal rate into the foreseeable future.

Besides the volume of data flowing through wireless networks, the number of connected devices is also expected to explode as a result of growth in machine-to-machine (M2M) deployments. As such, mobile data clearly needs to be proactively managed in order to keep CAPEX and OPEX under control, ensure fair use of network resources, guarantee quality of service (QoS), and enable operators to monetize their infrastructure investments.

The introduction of VoLTE, conversational video, and other such QoS-sensitive services makes this all the more critical. Certain key mechanisms such as policy and charging control (PCC) and deep packet inspection (DPI) can be employed to manage and monetize mobile data. These techniques should work flawlessly within a live network to meet the above-mentioned objectives, with comprehensive lab testing being the only way to ensure such cohesion.

End-to-End Testing within the Wireless Ecosystem

[Missing text /library/documenttype/WEB for zh]

Telecom operators are looking to serve their customers better and better to generate more revenue—and specifically, better average revenue per user (ARPU), with the goal of selling them new services and retaining the most profitable subscribers. Likewise, mobile operators are trying to draw subscribers into the same virtuous circle. The difficulty for mobile networks is that they are dependent on external resources: access networks are heterogeneous, the “last mile” is over the air, making it difficult to control its quality, and over-the-top (OTT) services are provided by third-party sources.
