Long term evolution technologies provide new standards in mobile communications regarding available bandwidth. It is expected that users of one radio cell will share more than 100 Mbit/s in future. To take advantage of the full feature set of next generation mobile networks, transport network design has to face new requirements, caused by the architectural(More)
The paper deals with the packet scheduling of voice traffic of IEEE 802.16e under femto cellular network where the length of wireless link is few meters. Instead of distribution of MCS (Modulation and Coding Scheme) levels of previous literature, only availability of traffic channel is considered in packet scheduling since the short wireless link of femto(More)
Standard optical fiber has potential capacity of multiple Tbit/s. Efficient utilization of the already installed fiber infrastructure is of outmost importance. Starting with passive wavelength division multiplexing (pWDM) this paper discusses the potential solutions for a managed optical lambda or a complete optical transmission layer independent of the(More)
