HDTV Almanac - Broadcast Battle

You can’t see them. You can’t hear them. You can’t touch them. Yet they are responsible for an enormous amount of our communication and entertainment. Most people would use the general term “radio waves” to refer to that part of the electromagnetic spectrum with wavelengths longer than visible light, but these are also used for cell phones, television stations, cordless phones, wireless networks, and an enormous range of other functions. Part of the reason to switch from analog to digital television was so that large sections of these frequencies could be put to other uses.

The FCC has been charged by Congress to come up with a plan for a nationwide wireless mobile broadband system, and industry groups are weighing in on the subject with extensive comments. Some sources claim that broadcast television is not using all of its assigned spectrum efficiently, and that some could be reassigned for broadband Internet services. Understandably, the TV broadcasters are asking the FCC to keep their hands off the TV frequencies.

The cell phone system has transformed both personal and business lifestyles. The Internet has also had a similar impact. A system that would give us broadband access to Internet content wherever we are would no doubt have a similar transformational effect. It could move us from the one-to-many model of radio and television broadcasts, and replace it with an on-demand system where individual consumers could choose what information they wanted, any time, anywhere. And just as people are giving up their landlines for cell phones, a wireless broadband system might eventually mean the end of broadcast television, cable service, and wired Internet access; the only wire coming to your home or office might be the power line.

The stakes are high in this debate about how we can best use the finite set of frequencies, so you can expect some strong statements coming from all the camps who might have an interest in the outcome. It’s not something that will be settled overnight, but it’s a major project with significant implications for how we get our information and entertainment in the future.

...which would put us back to that same old issue: "And when the power goes out." If you have a cell phone, and the power is out at the site your phone uses, what do you do? Particularly, what do you do if your end of that connection is also involved with an emergency? Same can be said for TV broadcasting, of course, but their power is usually even more protected than a cell tower, since there's lots fewer. To the extent most TV/radio broadcast sites usually have a backup generator, where cell sites don't. I'll take my land line phone and the OTA broadcast radio and TV, thank you very much. The rest will be nice, but not absolutely necessary - as it would if I didn't have access to land line and OTA....

I agree, when the power goes out, or there is a wide spread disaster the cell towers are going to be one of the first pieces of support structure to go. They balked at even having 4 to 8 hours of back up power. I doubt if many have more than a few minutes worth available. Then there is the saturation of the system when it is running. How many times have you heard "All circuits are busy" on a holiday week end, or sometimes just on week ends? They have had to set up priority over rides, or they were going to do so that the reporters couldn't tie up the available lines allowing emergency groups to still get through. Yes, we still have our land lines in addition to the cell phones, but even then there are microwave links on many trunk-lines.

All the gadgets are nice and I tend to be a first, or early adopter, but we need to keep the priorities straight even where both sides have money for their favorite politician's charity. <:-))...
