Abstract-Given that building occupants and more importantly public safety personnel regularly use stairwell to move about different floors in a multi-floor building, wireless network coverage for the setting may come as necessary in order to ensure seamless telecommunication connectivity. Nevertheless, wireless network planning pertaining to multi-floor stairwell scenario requires unique radio characterization since the scenario is different from other indoor environments. This paper presents a frequency dependent path loss and shadowing model for the multi-floor stairwell environment that was developed and tested at six dog-leg style stairwells. The empirical model covers frequency spectrum from 0.7 GHz up to 2.5 GHz which envelop numerous public safety and long term evolution operating bands. The model demonstrates good precision and is shown to outperform standard path loss model when comparison was made since it includes site-specific parameters describing radio characteristics natural to stairwell setting. The straightforward mathematical expression of the model can easily be applied when setting up or studying wireless network for the stipulated frequency range with respect to multi-floor stairwell.

“…An architectural view of MCN towards LTE-A is evaluated in [22]. LTE for public safety requires D2D communications also without the eNB coverage to guarantee the communication also in disaster areas [23]. D2D functionality for LTE technology is currently under standardization [24][25][26][27] and it brings many technical challenges [28,29].…”

LTE network is a good choice for delivering smart grid demand response (DR) traffic. However, LTE connectivity is not pervasively available due to smart meter improper positioning, limited of coverage, or base station software or hardware failures. In this paper, a solution is introduced to overcome issues relating to lack of LTE base station connectivity for user equipment (UE) considered as remote terminal units, i.e. communication interfaces connected to smart meters. The solution is an ad hoc mode for the LTEAdvanced UE. The ad hoc mode is applied to reach a relay node that is the nearest UE with base station connection. DR traffic is delivered between clusters of UEs and a relay node using multi-hop communications. Analytical Markov chain models and a Riverbed Modeler network simulation model are implemented to illustrate the functionalities and the performance when DR traffic is delivered with varying transmission power levels. A detailed physical layer propagation model for device-to-device communications, a static resource allocation in time domain, hybrid automatic repeat request retransmissions, and a capability for a UE to receive uplink transmissions are modeled both analytically and in the simulator. Both the disjoint analysis and simulations show that all packets are successfully transmitted at most with the fourth transmission attempt and the average network delay is low enough to support most of the smart grid DR applications (139.2-546.6 ms).

“…Thus, the characteristics of such LTE based public unity networks are already under consideration by the industriousness (Doumi et al, 2013). Moreover, LTE is an Orthogonal Frequency Division Multiple Access (OFDM) based radio access technology, with traditional OFDM on the downlink and Discrete Charles Fourier Transform (DFT)-spread OFDM (DFTS-OFDM) on the uplink.…”

The goal of this research is to evaluate the location accuracy of User Equipment (UE) in Long Term Evolution (LTE) networks which depends on the timing advance parameters. The ability to locate the subscribers through the network is considered as a significant factor in wireless communication systems. The main method to geolocation based on specified distances from many base stations is stated. The possibility of geolocating a Long Term Evolution (LTE) subscriber station based on the timing advance ranging parameter within the network signal internals is investigated in the paper. Also, simulation is used to describe performance in multiple base station networks that evaluating locations of subscriber stations on a two-dimensional system coordinated. Performance estimation of UE location in LTE networks was analyzed using simulations. Simulations were performed by using MATLAB. The main method for determining the subscriber station location depends on radial distances from multiple base stations. We observe from the results that the calculation error for the network is frivolous and by using four eNodeBs we obtain the most accurate estimation. Our simulation analysis shows that increasing the eNodeBs that used in the network leads to increasing the error to 29 centimeters.
