Transmission Speed

The transmission capacity and speed of access networks need to be continually increased as the transmission demands and data flows of the end-users grow steadily. Metallic cables and lines are still often used in both local area networks as well as access networks. Today, the G.fast lines with transmission speed of 1 Gbps working in 212 MHz frequency band are being deployed in practice, and a novel XG.fast conception with a frequency band up to 424 MHz is being developed. However, the future DSL solutions will soon reach GHz transmission bands in order to increase the transmission speed over metallic lines. Due to that it is necessary to investigate the behaviour and transmission characteristics of typical existing metallic lines in GHz frequency band and to develop accurate models to provide necessary estimations and modelling of in order to optimize transmission parameters, modulations and characteristics of future gigabit DSL solutions.

This work shows that in the frame of the stochastic generalization of the quantum hydrodynamic analogy (QHA) the uncertainty principle is fully compatible with the postulate of finite transmission speed of light and information. The theory shows that the measurement process performed in the large scale classical limit in presence of background noise, cannot have a duration smaller than the time need to the light to travel the distance up to which the quantum non-local interaction extend itself. The product of the minimum measuring time multiplied by the variance of energy fluctuation due to presence of stochastic noise shows to lead to the minimum uncertainty principle. The paper also shows that the uncertainty relations can be also derived if applied to the indetermination of position and momentum of a particle of mass m in a quantum fluctuating environment.
