Multilayer parking with screening on a random tree

In this paper we present a multilayer particle deposition model on a random tree. We derive the time dependent densities of the first and second layer analytically and show that in all trees the limiting density of the first layer exceeds the density in the second layer. We also provide a procedure to calculate higher layer densities and prove that random trees have a higher limiting density in the first layer than regular trees. Finally, we compare densities between the first and second layer and between regular and random trees.Comment: 15 pages, 2 figure

Analysis of interference to cable television due to mobile usage in the Digital Dividend

The start of use of mobile applications in the 800 MHz band, which forms part of the ‘Digital Dividend’, will cause interference to TV signals under certain conditions. The new mobile applications (called LTE, Long Term Evolution) use frequencies also used in cable TV networks. This report examines how much interference may occur when providing digital television over cable networks

Onderzoek naar storing op kabeltelevisie door mobiel gebruik in het Digitaal Dividend

De introductie van het gebruik van mobiele toepassingen in de 800 MHz band, die onderdeel vormt van het zogenaamde digitaal dividend, leidt onder bepaalde omstandigheden tot een verstoring van tv-signalen. De nieuwe (LTE) mobiele toepassingen gebruiken frequenties die ook worden toegepast in kabel-tv-netwerken. Dit rapport gaat in op de mate waarin deze storing kan plaatsvinden in het (digitale) televisie aanbod van de kabel.\u
