    In this issue of the History Column we bring you an article by Prof. Peter Kirstein, one of the original contributors to early packet switching. We are probably all familiar with the history of the Internet, beginning with its genesis in the American-developed ARPAnet of the late 1960s and early 1970s. We may be less familiar with the contributions of British researchers, as well as those in other... View full abstract»

    LTE is popularly called a 4G technology. It is an all-IP technology based on orthogonal frequency-division multiplexing (OFDM), which is more spectrally efficient - meaning it can deliver more bits per Hertz. This paper present the video, flay-rate pricing, and connected devices that all contribute to the growing demand for mobile data services. The world of telecommunications, people today are mo...

    A key aspect of the 3GPP system architecture evolution is the specification of an evolved packet core that supports multiple access networks. The EPC enables operators to deploy and operate one common packet core network for 3GPP radio accesses (E-UTRAN, UTRAN, and GERAN), as well as other wireless and wireline access networks (e.g., eHRPD, WLAN, WIMAX, and DSL/Cable), providing the operator with ...

    Policy and charging control provides operators with advanced tools for service-aware QoS and charging control. PCC for the evolved packet system, defined as part of the 3 GPP Release 8 specifications, has evolved significantly from previous releases to support multiple-access technologies, roaming, and mobility. Within the PCC framework, a number of protocols have been specified to implement these... View full abstract»

    In this article we describe the QoS concept of the evolved packet system, which was standardized in 3GPP Release 8. The concept provides access network operators and service operators with a set of tools to enable service and subscriber differentiation. Such tools are becoming increasingly important as operators are moving from a single to a multi-service offering at the same time as both the numb... View full abstract»

    The 3GPP Release 8 long term evolution/system architecture evolution marks the advancement of mobile cellular technology after UMTS-3G. The evolved packet system (EPS) architecture proposed in Release 8 introduces fundamental changes on top of UMTS in several design areas, including security. This article provides a tutorial overview of the proposed security mechanism in EPS. It first gives the ba... View full abstract»

    The 3GPP LTE standard is stable now in its first release (Release 8), and the question is how good its performance is in real-world scenarios. LTE is also a good base for further innovations, but it must be proven that they offer performance advantages for the price of their complexity. This article evaluates the performance of LTE Release 8 as a baseline and advanced concepts currently in discuss... View full abstract»

    Distributed transmit beamforming is a form of cooperative communication in which two or more information sources simultaneously transmit a common message and control the phase of their transmissions so that the signals constructively combine at an intended destination. Depending on the design objectives and constraints, the power gains of distributed beamforming can be translated into dramatic inc... View full abstract»

    Recent studies demonstrated that dynamic spectrum access can improve spectrum utilization significantly by allowing secondary unlicensed users to dynamically share the spectrum that is not used by the primary licensed users. Cognitive radio was proposed to promote the spectrum utilization by opportunistically exploiting the existence of spectrum "holes." Meanwhile, cooperative relay technology is ... View full abstract»

    The instability of wireless channels was a haunting issue in communications until recent exploration in utilizing variation. The same transmission might present significantly, and usually independently, different reception quality when broadcast to receivers at different locations. In addition, the same stationary receiver might experience drastic fluctuation over time as well. The combination of ... View full abstract»
