Neat. We're providing a limited wireless ISP service to business customers only. Only two pop's so far and using Lucent's COR/ROR for the backhaul. The pop's are only 4 miles apart. The remote is experiencing a lot of noise which has steadily built up over the last two years. We're in the process of moving it now. Typical CPE is either a linux box with pci pcmica card adapter and a orinoco card (my preference) or a Cisco pix with an ethernet converter. The ap's are AP-500's. I understand about the tuning aspects. Those grid antennae mounts are not what I'd called masters of precision, but they work well enough. _______________________________________________ Linux-users mailing list [EMAIL PROTECTED] Unsubscribe/Suspend/Etc -> http://www.linux-sxs.org/mailman/listinfo/linux-users
