Agreed. But PORTABILITY is a major consideration for WiFi networks. And I will bet that business people all over Phildelphia will use that WiFi network in their cars, even if it means, pulling to the side of the road in order too use a hot spot. Mobility has as much to do with the fact that THIS venue of information has wheels. But most vehicles do not spend all of their time moving. A car parked in a garage (home or work) can take advantage of a WiFi network to keep databases updated and to cache content that may be important to the owner of the vehicle. A cab with a touch screen information display can be updated in much the same way. And then there is the reality that it will be possible to use wireless point-of information/sales displays that can take advantage of data broadcast networks. Ubiquitous reception without cables IS what broadcasting is all about. We have a rich history of using radios and TVs in portable and mobile applications. There is NO REASON that a digital terrestrial broadcast system cannot build upon that heritage with a transmission system that is appropriate for the 21st century. > >Being able to receive at least the local channels >without having to have an infrastructure like cable >or DBS is an advantage even without mobility. Half a loaf. How much would people listen to radio if they could NOT receive it while driving? While TV and driving do not mix well, there is no reason to limit the transmission system to fixed receivers. We do not do this today with NTSC. Why take a step backwards with digital broadcasting? > >(distant channels are not relevant if local >> transmission facilities work properly); > >Distant channels are desirable for any real OTA >user.

They cannot get carriage on your cable system. You cannot get distant stations from a DBS provider unless you CANNOT receive the local terrestrial broadcast stations. While you (and Doug and Bob T) may find the ability to receive distant stations useful, in most cases there is little expansion of choice...mostly duplication of the same programming. A terrestrial broadcast system that delivers all of your local stations AND an additional 30-40 channels in the free & clear, would be INFINETLY more useful to most Americans. By the way, with such a system it is likely that you would always have access to those important network shows. The network affiliate relationship is crumbling anyway. Local broadcasters are going to need to learn how to live with what they can produce on their own, and the programming that they either develop or buy from syndicators. Making 30-50% profit margins for the privilege of being the local gatekeeper for a network is NOT a sustainable business model. With the spectrum utility idea, the networks will be able to bid directly for access to your market. IF there is a good business reason to continue an affiliate relationship in your market, then the station and network can bid together. What is more likely to happen is that stations will become the sales/operations front end for groups of channels within a market. They will sell ads for insertion into these channels, and provide the master control infrastructure for these channels. They may even provide hosting services for the local servers of national networks (servers that will be controlled by the nations network). And they will provide local content where it is economically feasible. What they will NOT be able to do is sit on their ass and make obscene profits.
