With a total of 13 patents to his name, Dodds has established himself as a key figure in innovation within the industry.

Latest Patents

One of Dodds' latest patents is titled "Wideband frequency domain reflectometry to determine the nature and location of subscriber line faults." This technique involves estimating distances and identifying irregularities and faults on telephone subscriber lines by measuring reflected test signals as a function of frequency. The measurements are adjusted for variable propagation velocity and line attenuation, and then transformed using the Fourier transform. The resulting amplitude and phase of peaks in the spectral domain help identify the distances to irregularities and the characteristics of reflection coefficients.

Another notable patent is "Extended distribution of ADSL signals." This invention describes a system where multiple metallic telephone lines carrying both baseband POTS (plain old telephone service) and DSL (digital subscriber line) signals are routed through a common field cabinet before reaching a central office. The arrangement allows for the removal of DSL/ADSL signals from the metallic lines, which are then transmitted using fiber optic broadband. This innovation significantly increases the distance over which ADSL services can be provided, overcoming limitations imposed by traditional metallic lines.
