Wireless synchronous broadband last mile access solutions for multimedia applications in license free frequency spectrums

A dominant percentage of last mile Internet connections within entire Europe are realized with copper cable pairs (POTL) which are limited in bandwidth by cable length (attenuation) and the number of XDSL lines in a telecommunication cable (crosstalk). Exposed users often cannot get state of the art broadband Internet connections for these reasons and in addition also have to share existing bandwidth with other users which can lead to low bitrates. Current trends show a strong demand of synchronous broadband Internet lines for high quality multimedia applications (e.g. VoD, online video communities and video conferencing). This paper will focus on alternative wireless synchronous license exempt optical and radio frequency wireless last mile access technologies and shows advantages and disadvantages between different methods.
