The peculiarity of voice transmission in IEEE 802.xx customer premise networks

Abstract

Nowadays local IEEE 802.3 protocol networks and wireless IEEE 802.11b networks became very popular. Unfortunately technology, built on the ground of these mentioned above networks and used in customer common telecommunication networks, creates particular problems, which appear while transmitting data traffic and also voice signals. In this article you can find mathematics methods of networks channel resource reservation. The examination has shown that while using the technology if IEEE 802.11b protocol for transmitting voice, the management information usually takes a bigger part of network throughput than voice packets. Those voice codecs that while analyzed separately reduce the rate of transmission data, are very ineffective in IEEE 802.11b networks. Judging on complex criteria for customer networks, it is recommended to code voice with G.711 protocol by grouping together voice data of 30 ms long to one packet, which consist max of 240 bytes.
