| Voice over Wi-Fi Capacity Planning | | 03/01/04, ITPapers.com | |
High-quality voice-over-Wi-Fi requires increased capacity in addition to enterprise-wide coverage. The range of an access point becomes a relatively irrelevant factor in a high-capacity voice-oriented network, and system capacity becomes the critical issue in delivering voice services with high QoS to high densities of voice handset users. Increased capacity requires more non-overlapping channels. 802.11b and 802.11g are limited to three (3) non-overlapping channels, while 802.11a offers up to 23 non-overlapping channels. This paper shows why 802.11a is therefore the most appropriate RF technology available to support high-quality voice applications in high-density environments. | |
