Wireless is a good option with a few caveats: 1. At the speeds you are talking about, you need line of sight. Usually, this means getting up high to account for curvature of the earth and clearing of what is called the fresnel zone for the particular frequency you are using. 2. You will need to use some of the higher frequency systems to get link speeds of a gig or more. There are 23ghz unlicensed systems as well as 60ghz unlicensed systems. The 60ghz systems will get you higher speeds but the link distance will be on the order of hundereds of meters. 3. Link planning will be a critical exercise. If you really NEED the high availability, you can get it by properly considering the distance you need to go, the speeds you will use, the frequencies you will transmit at, and the statistical expectations of weather and other factors that will affect the total path attenuation the system will encounter. Systems that average availability of 99.99% are commonplace and 99.999% can be achieved by using shorter path distances. Try the guys at www.ydi.com.

Looking for any advice or pointers for obtaining multiple Gig links (last mile) in the Plano, TX area. The abundance of fiber options here seems to be decidedly underwhelming. Looking for suggestions including creative options such as wireless. I need to get from Plano to any closest better place for picking up multiple Gig Internet links. Wondering too what other large companies in this area have done for large internet links...any advice appreciated.
Also, I'm reading now that more ISP's are using wireless for last mile provisioning on the new unlicensed frequencies. Was wondering if anyone had experience using Dragonwave or any similar wireless products in Texas. Do sandstorms and golf ball sized hail pose significant issues? Severe thunderstorms? Would like to chat with anyone with significant wireless experience in the Dallas area. WOuldnt mind speaking with an unfluffed sales person eitehr. :-)
