Consideration of IP Telephony Quality on the IEEE802.11a Wireless LAN
TLDR
In this paper, we discuss about the quality of IP telephony service on the IEEE802.11a wireless LAN from the aspect of R-value, and show ability to improve theIP telephony quality on the Hot-Spot network employing PLC function defined in the ITU-T Recommendation G.711 Appendix I. Expand
An Optimum Model to Estimate Path Losses for 400 MHz Band Land Mobile Radio
TLDR
In this paper, conventional path loss models, i.e. the diffraction model, Okumura model and two-ray model, were evaluated with 400 MHz land mobile radio field measurements, and a method of improving path loss estimation by using each of these conventional models selectively was proposed. Expand
An optimum model to estimate path losses for 400‐MHz‐band land mobile radio
TLDR
A method for improving path loss estimation by using each of these conventional models selectively was proposed for land mobile radio field measurements. Expand
Influence of multi-rate control function on the end-to-end latency of multi-hop wireless LAN
TLDR
The influence of the multi-rate control on the end-to-end latency in multi-hop wireless networks is evaluated through certain experiments. Expand
