Nathan, The Spectralink Link WTS uses a proprietary MAC and radio, operating in the 902-928 MHz band. Their Netlink product uses 802.11b with their proprietary SVP QoS mechanism, which, contrary to their claims, is not compliant with the 802.11 standard. See http://www.spectralink.com/products/svp.html and http://www.spectralink.com/products/pdfs/SVP_white_paper.pdf for more details. Effectively, SVP requires that the 802.11 CSMA/CA access control mechanism ignore the normal shared access rules.

How do they guarantee the datarate (64 or 32kbps) required for the telephony over their network. Does anyone know if they're using a proprietary MAC for this? And what's the latency like as they add more users, does the delay start to sound like a satelite link? I can see that with 802.11b @ 11Mbps then can certainly provide the capacity for multiple voice-users, but what if another 802.11b network interfered with them? In CSMA mode they'd have to fight it out. Are they using PCF mode and simply hogging the entire local bandwidth. Any thoughts, answers would be appreciated, thanks.
