Prices for Long - Distance Voice Telephony in Germany
This paper examines the first 16 months of competition in the German market for long-distance voice telephony on the fixed network. It concentrates on price level and price structure. Competition induced by the entry of both network operators and switch-based service providers decreased the price level substantially. Furthermore, after initial attempts to design innovative price structures, mos...
متن کاملINTERNET telephony or Internet TELEPHONY?
Internet telephony (or VoIP) has been viewed in two different ways. First, some hold that it is largely similar to earlier architectural changes in the PSTN, continuing the transition from analog to circuit-switched digital and now to packet-switched transmission.

متن کاملLong distance tunneling
Quantum tunneling between two potential wells in a magnetic field can be strongly increased when the potential barrier varies in the direction perpendicular to the line connecting the two wells and remains constant along this line. A periodic structure of the wave function is formed in the direction joining the wells. The resulting motion can be coherent like motion in a conventional narrow ban...
