“…The next evolutionary step, LTE Advanced, is expected to provide peak data rates of even 3 gigabits per second for down-and 1.5 gigabits per second for uplink. However, as shown in (Tenorio et al, 2010), actual bandwidth highly depends on signal strength and the number of users in a network cell and can be much lower than the nominal value. The fastest currently sup-ported 3G network standard in Germany is DC-HSPA with a nominal downlink data rate of 42 Mbps and 10 Mbps uplink, which is provided by Telekom Deutschland GmbH.…”

The possibility to provision road vehicles unmanned and on demand will have an important influence on the development of new mobility concepts. We therefore present the teleoperated driving of road vehicles. This paper outlines the basic concepts, including a static multi-camera design, an operator interface with a sensor fusion based display, and a cellular network based video transmission and communication architecture. We also show how we manage to fulfill the system's technical requirements with our hard-and software design and point out the occurring problems due to communication limitations and lack of situation awareness. Finally, we propose solutions to guarantee driving safety.

“…The flagship features of Rel'7 are 64QAM and MIMO [1] -with both relying on the use of the "Enhanced Layer 2" feature -have been tested [2] and to varying degrees deployed in wireless networks. Subsequent releases beyond 3GPP Rel'7 will further increase attainable throughputs with the introduction of these features deployed over two or more carriers in combination or separately.…”

3GPP Release 7 introduced several new powerful features to the existing HSDPA (High Speed Downlink Packet Access) functionality including Single Input Multiple Output using 64 Quadrature Amplitude Modulation (SIMO 64 QAM) and Multiple Input Multiple Output (MIMO). Amongst these, first implementations of MIMO brought about inadvertent performance degradation in existing non MIMO devices and terminals in the field. The objective of this paper is to provide an insight into a solution initially sought to resolve this MIMO coexistence issue using already available Virtual Antenna Mapping (VAM) and its modification which resulted in a valuable optimisation technique in itself -"Enhanced VAM" -irrespective of MIMO deployment.

“…Results have shown that LTE outperforms HSDPA in terms of spectral efficiency and user throughput. In [23], the main objective of the work was to provide an insight into the potential of HSPA+ technology as a means to enhance user experience against prior HSPA mobile broadband capabilities such as "HSDPA 7.2 and HSDPA 10.8 (SIMO 16QAM). The performance benchmark was the outcome of field tests pioneered by Vodafone, in its Vodafone Spain network, and carried out over commercial product platforms.…”

Esta es la versión de autor de la comunicación de congreso publicada en: This is an author produced version of a paper published in: . It is found that increasing the sector range from 500m to 1000m will increase the sector downlink capacity. Also, it is found that increasing the value of the propagation parameters (σ 1 and σ 2 ) will reduce the downlink sector capacity. It is noticed that, the effect of changing the propagation exponent s 1 is null while increasing the propagation exponent s 2 will increase the downlink capacity.
