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/s

RE: [BAWUG] beacon frames and channels

2003-10-13 Thread Bob O';Hara
One other possibility is that the receiver is near to a very high powered AP and there is enough energy in the signal to recover it far from its transmitted channel. This can be easily demonstrated with a Cisco 1200 AP, transmitting at full power (100mW) on channel 6. Within about 20 feet, the Be

Simon's point is a good one. The European regulatory requirements are addressed in 802.11h, a new amendment to the 802.11 standard published earlier this month. With the WRC'03 results on the future of the 5 GHz band, this requirement will be likely to spread to other areas, as well. The US na

2003-10-31 Thread Bob O';Hara
Vinod, There is nothing in 802.11 that coordinates the channel assignment of APs. So by necessity, anything that does so is proprietary. However, there is new work being investigated in the IETF, called CAPWAP (control and provisioning of wireless access points) that would address this issue. T

RE: [BAWUG] Dynamic WEP Keys

2003-12-03 Thread Bob O';Hara
Actually, the answer is yes, you can support dynamic WEP keys without an EAP authentication method. The way to do this is with a pre-shared key. This requires entering a key or pass phrase on both the client and AP, and enabling WPA-PSK as the security method. The AP and client then use the EAPOL

Simon is quite correct. Any AP that attempts to present multiple SSIDs without each SSID having a unique BSSID is VERY likely to not be compatible with the majority of client cards that are out there. One thing that Simon is not quite correct about is that you have to wait for next year to get "t

2003-12-19 Thread Bob O';Hara
I agree with Simon that a single AP with multiple BSSIDs/SSIDs should not cause any QoS problems. Rather the contrary, as Simon points out. It is much easier to coordinate QoS in a single AP than in several, independent APs. The clients contribute the same amount of trouble for QoS in both cases.
