<..Then how will the fiber capacity being installed now ever be utilized if it is limited by existing copper and limitation of wireless?..> Again, think of the efficient design of the circulatory or respiratory systems (or your local water plant). FAT pipes at source, narrowing as they spread out in many smaller local feeders. There will always be (as physically there NEEDS to be) a gradient from the backbone into the local feed. Certainly at SOME point as our backbone grows significantly (10-20 years?), the cost to install fiber to the enterprise may be necessary for more and more businesses and applications. But I'm guessing that greater efficiencies in squeezing out wirless channel capacity will keep this technology out front for MOST requirements for quite a while. Certainly long after copper is insufficient. BTW - go DCLK. (4th biggest position, in at $34). And go ARTT!

Ali: Fiber versus wireless. Fiber has huge BW, but is extremely costly to install, so that it can reach few locations. Wireless has less BW, but can go anywhere. So, fiber is a natural for the trunk of any communications network. By trunk, I mean not only city to city connections, but connections all the way to the neighborhood. For the last stretch you have 4 choices: wireless, cable, xDSL, or fiber for buildings that have a high user denaity. Broadband wireless has more BW than either cable or xDSL (even VDSL) solutions. To go back to BR's analogy. if you think of a road network, fiber is the freeways. Wireless/cable/xDSL are the local roads. Narrowband modems or narrowband wireless options are the dirt roads.
