Release 8 (hereinafter referred to as “LTE Rel. 8”) specifications [1][2] which completed standardization by the 3GPP in the spring of 2009. LTE Rel. 8 adopts various high-level radio interface technologies such as orthogonal multi-access, frequency-domain scheduling and Multiple Input Multiple Output (MIMO) *2 , and provides even higher system capacity and cell edge user throughput than High S...

This paper introduces an experimental testbed developed at the University of Malaga to analyze the behavior of mobile applications and services over LTE (Long Term Evolution) networks. The novelty of the testbed is the ability to correlate the impact of radio propagation issues on LTE configurations and applications protocols and cross tuning LTE parameters and IP protocols from the point of vi...

The industry landscape in telecommunications is changing rapidly at the moment. Services are increasingly shifting from voice to data and from circuit-switched to packet-switched ones. LTE and WiMAX are the two technologies poised to dominate next generation mobile networks. Battle between LTE & WiMAX technologies is already heating up with WiMAX being ahead due to availability of standards thr...

This paper provides a high-level overview of some technology components currently considered for the evolution of LTE, referred to as LTE-Advanced. First, a brief overview of LTE and some of its technologies are given and then the IMT-Advanced requirements are discussed. One of the targets with the evolution of LTE is to reach or seven surpass these requirements. The technology components consi...

Correspondence Dongxiao Liu, Department of Electrical and Computer Engineering, University of Waterloo, Waterloo Canada N2L 3G1 Email: [email protected] Cellular technologies, in particular the current long-term evolution (LTE) and future 5G, are suitable for implementing vehicle-to-everything (V2X) services, due to the existing network infrastructure, device-to-device (D2D) communicati...

This paper presents the concepts of network virtualization, focusing specifically on wireless virtualization of the LTE mobile communication system. A novel wireless virtualization framework is proposed and developed, which allows mobile network operators to share the wireless spectrum, as well as, the infrastructure (i.e., hardwares equipment). The framework targets the concepts of wireless vi...

Relaying is one of the proposed technologies for LTE-Advanced networks. In order to enable a flexible and reliable relaying support, the currently adopted architectural structure of LTE networks has to be modified. In this paper, we extend the LTE architecture to enable dynamic relaying, while maintaining backward compatibility with LTE Release 8 user equipments, and without limiting the flexib...

Internet of Things, an increasing number of machine to machine (M2M) devices are being deployed. In particular, one of the M2M applications, video surveillance, has been widely discussed. Long Term Evolution (LTE), which can provide a high rate of data transmission and wide range of coverage, is a promising standard to serve as an M2M video surveillance system. In this paper, we studied a perfo...
