"The Performance of 3G and 4G Cellular Systems";
Vortrag: The Future of Wireless Access Workshop Programme, Southampton (eingeladen); 31.10.2011 - 01.11.2011.

This contribution provides insight into the
performance of the currently deployed 3G cellular
systems HSDPA and WiMAX. In extensive
measurement campaigns we measured the physical
layer throughput of these 3G systems in different
environments (alpine and urban) and compare
the results rigorously to their upper bounds
derived from the well known Shannon capacity.
By separating the observed losses into a channel
state information loss, a design loss, and an
implementation loss, we gain more insight into
the performance of the different standards which
in turn allows us to compare them better and to
localize their shortcomings. In general, we find
that implementations of the current standards still
operate about 10 dB away from the Shannon
bound. We finally consider 4G LTE systems with
up to eight antennas and find that they are not
considerably better with respect to bandwidth
efficieny.
