Untitled ItemEnhanced Connectivity and Energy Efficient Networking for
Modern Railways Communication Systems
Abstract
To meet the increasing demands for passenger data rates, modern
railway communication networks face significant challenges. The advent
of 5G communications after the long-term evolution (LTE) and
LTE-Advanced (LTE-A) systems provides several technological advances to
address these challenges. In this paper, after reviewing the main 5G
communication aspects for modern railways, we present methods to ensure
connectivity and energy efficiency for the passengers’ user equipment
(UE) through the use of mobile relays (MRs) on top of the train wagons
in conjunction with intelligent resource allocation. Relevant challenges
to train connectivity are also presented, and suitable solutions are
outlined.
