Challenges and Solutions in Prototyping 5G Radio Access Network


Breakthroughs in wireless networks will drive commerce and enhance society in entirely new and unexpected ways. A key component of the wireless future will be the widespread deployment of 5G wireless networks.


The primary goals of 5G are to support a 1,000-fold gain in capacity, connections for at least 100 billion devices, and 10Gb/s delivered to individual users. Additionally, these new networks will be capable of providing mass low-latency connectivity between people, machines, and devices. Deployment of 5G networks is expected to commence in 2020. 5G radio access will be built using evolved existing wireless radio access technologies (RAT) such as LTE and WiFi combined with entirely new technologies.

A DYNAMIC GRAPH OPTIMIZATION FRAMEWORK FOR MULTIHOP DEVICE-TO-DEVICE COMMUNICATION UNDERLAYING CELLULAR NETWORKS


With emerging demands for local area and popular content sharing services, multihop device-to-device communication is conceived as a vital component of next-generation cellular networks to improve spectral reuse, bring hop gains, and enhance system capacity. Ripening these benefits depends on fundamentally understanding its potential performance impacts and efficiently solving several main technical problems.



Aiming to establish a new paradigm for the analysis and design of multihop D2D communications,
in this article, we propose a dynamic graph optimization framework that enables the modeling of large-scale systems with multiple D2D pairs and node mobility patterns. By inherently modeling the main technological problems for multihop D2D communications, this framework benefits investigation of theoretical performance limits and studying the optimal system design. Furthermore, these achievable benefits are demonstrated by examples of simulations under a realistic multihop D2D communication underlaying cellular network.

How Mobile is Enabling Tech to Outgrow the Tech Industry


Android devices are still the driving force across the global smartphone market, according to the International Data Corporation. Total smartphone shipments are set to reach 1.3 billion units this year with Android accounting for over 80 percent compared to just under 14 percent for iOS. 



From a revenue perspective, Apple’s premium smartphones control 30 percent of global revenue while Android’s more layered approach will afford it just under 67 percent.

Bringing Network Function Virtualization to LTE


The mobile telecommunications industry is at the verge of a unique business crossroads. The growing gap between capacity and demand is an urgent call for new approaches and alternative network technologies to enable mobile operators to achieve more with less.

Today, mobile broadband data is growing at an annual rate of 40-50 percent per year in the U.S. and other regions globally. Mobile service providers address these rapidly expanding traffic volumes through deployment of additional network functions, which will be a significant capital expenditure (CAPEX) challenge. The nature of that mobile broadband data traffic is also evolving with new services including new video applications, connected cars and the Internet of Things (IoT). This rapid capacity growth and increasing traffic diversity in LTE networks stresses the assumptions of existing network architectures and operational paradigms.

Creating a Digital 6th Sense with LTE Direct


LTE Direct is an innovative device-to-device proximal discovery technology that can be efficiently integrated with LTE Advanced services and networks. It is defined as part of the global 3GPP standard, as a feature in Release 12. LTE Direct will make users aware of what’s happening around them at all times, effortlessly and privately, changing how people socialize and interact with people and things.

Requirements, Challenges, and Technologies for 5G of Terrestrial Mobile Telecommunication


In this article, a summary of the 5G mobile communication requirements and challenges is provided. First, essential requirements for 5G are pointed out, including higher traffic volume, indoor or hotspot traffic, and spectrum, energy, and cost efficiency. Along with these changes of requirements, a potential step change for the evolution toward 5G, which shows that macro-local coexisting and coordinating paths will replace one macro-dominated path as in 4G and before is presented. 



A discussion on emerging technologies for 5G within international mobile telecommunications is given. Challenges and directions in hardware, including integrated circuits and passive components, are also discussed. Finally, a whole picture for the evolution to 5G is predicted and presented.

The Impact of SPDY on mobile broadband ecosystem and value added services (VAS)


The growing rate of encryption, especially SPDY-encrypted Hypertext Transfer Protocol (HTTP) over mobile wireless networks, has both immediate and long-term impacts on the mobile broadband ecosystem and wireless technology architectures. As the rate of encryption grows, Mobile Service Providers (MSPs) are forced to rethink their service offerings and value proposition, how they manage capacity and customer experience and how value-added services will be impacted.

The term SPDY, pronounced “speedy”, was established and trademarked by Google and is not an acronym. It was developed as an open networking protocol for transporting web content. SPDY encapsulates multiple HTTP flows in a TLS header, with particular goals of reducing web page load latency and improving web security. SPDY achieves reduced latency through HTTP header compression, stream multiplexing, and request prioritization. As of July 2012, the group developing SPDY has stated publicly that it is working toward standardization (internet draft).

The Role of Small Cells, Coordinated Multipoint, and Massive MIMO in 5G


5G will have to support a multitude of new applications with a wide variety of requirements, including higher peak and user data rates, reduced latency, enhanced indoor coverage, increased number of devices, and so on. The expected traffic growth in 10 or more years from now can be satisfied by the combined use of more spectrum, higher spectral efficiency, and densification of cells. The focus of the present article is on advanced techniques for higher spectral efficiency and improved coverage for cell edge users. A smart combination of small cells, joint transmission coordinated multipoint (JT CoMP), and massive MIMO to enhance the spectral efficiency with affordable complexity is proposed.

A review of recent achievements in the transition from theoretical to practical concepts and note future research directions is proposed. Its show in measurements with macro-plus-smallcell scenarios that spectral efficiency can be improved by flexible clustering and efficient user selection, and that adaptive feedback compression is beneficial to reduce the overhead significantly.  READ FURTHER;
