Tiivistelmä
The effective and efficient use of communication technologies during the disaster sce-narios is vital for the relief and rescue works as well as for the disaster affected people. During the disaster scenarios, links between the Radio Access Network (RAN) and the Core Network (CN) might be broken in the disaster affected areas. If the link between such affected eNodeBs can be established, the data from the user can be transported to the network via node-to-node communication. Thus, this utilization of cellular mobile networks for the communication during such scenarios can be a key technological achievement.
The goal of this thesis is to study the possible realization of the BS of the mobile network as a sensor node during the disaster scenarios for the detection of such scenari-os and to study the possible implementation of the node-to-node communication be-tween the BSs for the reliable delivery of the user data to the network. This thesis exam-ines the possibility of this inter-node communication for 3rd Generation Partnership Pro-ject (3GPP) Long Term Evolution (LTE). The merits of the LTE technology and its specifications have been deeply studied.
The calculation in the analysis part shows that node-to-node communication is pos-sible in LTE. A probable frequency reuse plan for the node-to-node communication, which is proposed in this thesis, is a result of the bandwidth scalability property of LTE. The result from the theoretical analysis shows that Signal to Interference plus Noise Ra-tio (SINR) of 5.92 dB can be achieved during such communication. This SINR value can support Quadrature Phase Shift Keying (QPSK) modulation technique with 3/4 or 4/5 code rate for the bandwidth of 2.5 MHz. The Multiple-Input Multiple-Output (MIMO) technology in the LTE specification helps to provide additional increase in the data rates. The simplest communication mode can provide the data rates of 1.86 Mbps whereas 4 x 4 MIMO can provide up to 7.5 Mbps. Further, the proposed framework can be considered as the base for the implementation of node-to-node communication.
This master thesis work has considered LTE as a communication technology for the study of a probable communication technology during the disaster scenarios. The flexi-bility in the utilization of the bandwidth in LTE provides the possibility for the node-to-node communication. The utilization of frequency band in Global System for Mobile Communication (GSM) also provides the possibility for the node-to-node communica-tion as well. However in Universal Mobile Telecommunication System (UMTS), the frequency band is the limitation for implementing the node-to-node communication. In UMTS, the interference will be very high because of the 5 MHz fixed frequency band implementation.
