Issues that must be addressed to realize the 5G architecture vision

Issues to be addressed: How legacy networks will interface and interoperate with the new network architecture  Determining the optimal physical realization of the network cloud to meet performance and cost targets. Whereas centralization of resources could result in savings from pooling, it could also lead to performance bottlenecks, higher latency, and single points of failure. …

5G challenges, potential enablers, and design principles.

Based on current trends, it is generally understood that 5G mobile networks must address six challenges that are not adequately addressed by state-of-the-art deployed networks (Long Term Evolution-Advanced, LTE-A): higher capacity, higher data rate, lower E2E latency, massive device connectivity, reduced capital and operations cost, and consistent QoE provisioning. These challenges are shown in the …

Time spent on apps on mobile devices in the United States (A June 2015 Outlook)

Mobile apps began to appear in 2008 and were originally designed for simple information retrieval in the form of calendars, email and weather forecasts. However their popularity quickly encouraged developers to expand into other categories including gaming, banking and shopping apps. Time spent on selected mobile social networks in the U.S. has been measured in billion …

Battery Life Is A Key Feature For Mobile Devices

Designing a smartphone is ultimately a game of trade-offs: screen size vs. portability; battery life vs. data speeds; appearance vs. sturdiness. Just to name a few. To make these trade-offs, it’s important to know what the consumer wants. This chart shows which improvements are the most wanted by mobile device users across five countries. Amazing …

FUTURE CHALLENGES IN 5G WIRELESS COMMUNICATION NETWORKS

The fourth generation wireless communication systems have been deployed or are soon to be deployed in many countries. However, with an explosion of wireless mobile devices and services, there are still some challenges that cannot be accommodated even by 4G, such as the spectrum crisis and high energy consumption. A question to be raised as the …

Big Data for Communication Service Providers (CSPs)

People, devices and networks are constantly generating data. When users stream videos, play the latest game with friends, or make in-app purchases, their activity generates data about their needs and preferences, as well as their QoE. Even when users put their devices in their pockets, the network is generating location and other data that keeps …

High Speed Broadband Mobile Services: What The Customers Are Waiting For

Demands for wireless data services are showing rapid growth due to evolved networks for high-speed connectivity, wide-scale deployment, flat-rate pricing plans and Internet-friendly devices (smartphones). Consumers rely heavily, and often exclusively, on mobile devices for their communications needs. Therefore, the normal trend is to require, from the mobile system, the same performances as the one …
