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;

Scenarios for 5G Mobile and Wireless Communications: The Vision of the METIS Project

METIS is the EU flagship 5G project with the objective of laying the foundation for 5G systems and building consensus prior to standardization. The METIS overall approach toward 5G builds on the evolution of existing technologies complemented by new radio concepts that are designed to meet the new and challenging requirements of use cases today’s radio access networks cannot support.

The integration of these new radio concepts, such as massive MIMO, ultra dense networks, moving networks, and device-to-device, ultra reliable, and massive machine communications, will allow 5G to support the expected increase in mobile data volume while broadening the range of application domains that mobile communications can support beyond 2020. In this article, scenarios are identified for the purpose of driving the 5G research direction. Get further insights from the presentation below;

Some InfoGraphics - Why Facebook had to go after WhatsApp

When Facebook announced that it would pay a total of $19 billion to acquire WhatsApp, many were astouned by the price. Considering WhatsApp's huge and immensely engaged user base though, $19 billion doesn't seem as much anymore. Here are stats from  That could justify this.. look below;

4G Mobile Broadband Evolution: 3GPP Release 11 & Release 12 and Beyond

At the grassroots level, this confidence may be attributed to the careful science of technology standards developed by the 3rd Generation Partnership Project (3GPP). The standards work by 3GPP, the foundation of the world’s mobile broadband infrastructure, is delivering international communications technologies to the masses via the Global System for Mobile Communications (GSM) family of technologies, which is interchangeably called the 3GPP family of technologies as they are based on the evolution of standards developed for GSM, Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunication System (UMTS), High Speed Packet Access (HSPA), HSPA+, Long Term Evolution (LTE) and LTE-Advanced.
