In what city are you located? We provide broadband bandwidth to local ISPs for sale to their customers. As well we work with other wireless companies on these projects. Let me know where you are and we can try to answer your questions. Thanks. At 11:41 AM 2/6/98 -0500, Jeff Studds wrote: >>Date: Thu, 05 Feb 1998 16:14:43 -0600 >>From: "Louis A.
