RESEARCH OF LOW-BANDWIDTH RADIONETWORKS QOS PARAMETERS

Irina Strelkovskaya, Roman Zolotukhin

Abstract


Background. This article describes the research of QoS parameters in low-bandwidth communication networks based on VHF (Very High Frequency) radio stations produced by Aselsan (Turkey) and Harris (USA).
Objective. The aim of the paper is the research of data transfer delay, jitter of data transfer delay, packet losses and analysis of the possibility of different data traffic types to pass through VHF radio channels.
Methods. The program "iperf-v2.0.5", the system utility "ping" and the software "Packet Sender" were used to experimentally research the QoS parameters of low-bandwidth radio networks.
Results. The obtained data concerning the QoS parameters of low-bandwidth radio networks was applied to improve special software "DSS Telecard" of LLC «Telecard-Prilad». which resulted in the increase of maximum users number in the VHF radio networks by 60%.
Conclusions. The research of QoS parameters in VHF radio networks was performed and recommendations upon the operation in low-bandwidth radio networks were provided for the use in the “DSS Telecard” software of LLC «Telecard- Prilad».


Keywords


radio station; VHF; QoS; data transfer rate; jitter; packet loss; ping.
