Lonliness of the Long Distance Landline

The latest telephone usage statistics confirm what we've already suspected. People are running away from landlines like they're allergic to copper. If Alexander Graham Bell came back to life in his lab today and spilled battery acid in his lap, he'd be screaming for Watson in his prototype transmitter to no avail. Nobody would be listening at the other end of that wire. Now if he had the presence of mind to whip out his cell phone and select the picture of Mr. Watson as one of his favorites, that call would likely go through. Watson, like just about everybody else, has gone wireless.

It's no surprise that most everyone carries a cell phone. They probably have two or three more old ones, sitting in a drawer, that should be recycled. People just love staying connected. They're on those phones even when they shouldn't be. Sit at any stop light and watch the cars turning left in front of you. About every third one has a driver on the phone. Sadly, one too many of those has a cigarette in the other hand is driving with their elbows. Ma Bell would never have sat still for that.

Ma didn't have to. In the days when houses were built with special nooks for the telephone set, you needed wires to make anything happen. Those wires might happen to include a run of barbed wire cattle fence. No matter. It was the requirement for electrical conductors that led to the universal copper pair that runs to every home and business. But the way things are going, you might as well dig up that copper and use it to make pennies. People are abandoning their landlines. Today 30% wouldn't pick up a home phone even if it rang.

My how things have changed. Growing up in our house I remember everyone but my grandmother being thrilled when we finally got off the neighborhood party line and got our own private phone line. I used to watch her comically sitting at the desk with her hand cupped over the transmitter of our one heavy flat-black non-dial telephone set. Neighborhood conversations were at least as amusing as the early TV shows. By the time I became a homeowner, there were outlets for telephones in just about every room including the basement. Your phone was your connection to everyone near and far. You wanted your number printed in the telephone directory so that people could find you.

At my house, we're the kind of people who just wouldn't feel right if there wasn't a telephone hanging on the wall or sitting on the desk. Who isn't? Younger people. Those who have no memory of "number, please" operators or a day when the term "cell phone" sounded like something you'd find in a prison. That's everybody under 30. A third of those have only a cell phone. If mom wants to call, she better have the number written down. It's not published.

There's another group that's somewhere in the middle. They either have regular landline telephone service but don't use it, or they've moved on to the latest technology. Cable companies want to be in the phone business. They offer bundles of TV, phone service and broadband Internet called "triple play". The telephone service actually uses the broadband rather than standard phone wires. This is VoIP or Voice over Internet Protocol. It's big advantage is that you can get more features for less money, especially in a bundled service. It does have the annoying problem of going dead when the power goes out or when the Cable broadband dumps. Then you use your cell phone.

But if you are going to use your cell phone some of the time at home and all of the time while mobile, why bother with a landline or VoIP phone service at all? That's what the younger generations think. Many kids today get their first cell phone when they are in high school, take it to college, and by the time they're out in the world everybody they want to talk to knows their cell number. Why not just keep the cell on at home instead of having a completely different number or a "find me follow me" setup? You don't need finding or following if you only have one number.

Along with landlines, the concept of competitive long distance phone service is fading from the scene. This was one of the first products of phone system deregulation. You could save a lot of money by switching to an alternative provider, and probably still can if you are a heavy landline user. This service was so aggressively marketed that it became a TV punchline for someone to pick up a ringing phone during dinner and say: "No, I don't want to switch my long distance phone service."

Now, what's long distance? Most cellular service plans work the same whether you are calling across town or across the country. You buy bundles of anytime minutes and just make sure you don't go over your monthly limit. If that's a chronic problem, you can now get plans with unlimited anytime minutes.

Long distance still comes into play for international calling. If you have relatives or business associates overseas, you're sensitive to international rates. International minutes are almost always an additional charge. You can keep your costs down by using low rate International calling cards and whatever phone you wish. This is also probably the best justification for VoIP going forward. Simply coordinate with your contacts overseas to use the same VoIP service, and your "on network" calls are free. The Internet becomes the phone line.

Verizon has a interesting approach whereby fiber optic cable replaces your TV coaxial cable, your telephone line, and your DSL or Cable broadband connection. Signals beamed through glass fibers are far faster and more flexible than other technologies. So much so that TV, broadband Internet and telephone service all have their own wavelengths and don't interfere with each other. In this case, the telephone company is taking over the television business and perhaps preserving the legacy of home phone service for future generations.

Media Flos to Mobile TV

LG VX9400 MediaFLO enabled phone for Verizon.Television is pervasive. Once limited to high power over-the-air broadcasting, TV has been glomping onto other delivery mediums as fast as it can find them. First came cable channels that had no over the air equivalents. Then satellite, with its almost universal reach. Next, the Internet with clips on YouTube and IPTV feeds from network owned Websites. Now the move is to cell phones and other wireless devices for truly mobile TV.

The original approach to mobile video was downloadable clips using the cellular broadband networks, such as EV-DO for Verizon and Sprint. But cell phone network operators are running into the same limitations as Internet content delivery. The available bandwidth isn't high enough for really good real-time video presentation, and the sheer volume of packets threatens to bring down the whole network if the service truly catches on. What's been needed is a new delivery network designed for video from the ground up.

The leading candidate for that new network is Qualcomm's MediaFLO. Verizon Wireless started adopting it about a year ago and AT&T has just announced that it will begin service too. What's special about MediaFLO? First, it delivers its content using a different over-the-air channel than the cellular frequencies. Second, it's designed for real-time viewing at 30 frames per second to give a true live television experience. A typical screen size is QVGA (Quarter Video Graphics Array) at 240x320 pixels. Since mobile devices aren't likely to tote around living room sized video displays, a lower bandwidth is acceptable to provide a good viewing experience. MediaFLO needs just 300 Kbps per live channel.

The MediaFLO specification supports many possible deployment schemes, but the one that is winning out is the former UHF TV channel 55 at 716-722 MHz. It is part of the lower 700 MHz band sold to Wireless companies by an earlier FCC auction and offers licensed high power transmission with large coverage areas. With 50 KW of effective radiated power and a 6 MHz bandwidth, MediaFLO transmitters can provide up to 20 live mobile TV channels with stereo sound over a substantial service area.

Another advantage over IP and cellular broadband delivery is that FLO TV service is multicast, like regular television. That means that the same bandwidth is used regardless of how many viewers there are. Internet based services usually need a certain amount of bandwidth for each user, especially for last-mile delivery. The FLO in MediaFLO stands for Forward Link Only to designate that this is a one-way transmission system.

A typical MediaFLO enabled cell phone is the one being sold by Verizon. It's 320x240 pixel high resolution color display (262,000 colors) rotates from portrait style when used as a cell phone to a landscape mode for TV viewing. You pull up a 5 inch TV whip antenna when needed to get a strong signal. This phone also supports Verizon's V Cast video services using the EV-DO cellular broadband system with up to 700 KHz download speed.

Another MediaFLO phone for Verizon is the Samsung SCH-U620, the first one offered by Verizon for mobile television. This is a slider phone with a similar screen size and V Cast capabilities. Plus all the usual niceties such as streaming Bluetooth and a Megapixel camera.

AT&T is planning to offer two cell phones of its own that will be MediaFLO enabled. They are the LG Vu and Samsung Access.

MediaFLO is aggressively marketing its technology and adding content that now includes CBS, Comedy Central, ESPN, FOX, MTV, NBC and Nickelodeon. Coverage is still limited to major metropolitan areas, but the fierce competition that will no doubt ensue between AT&T and Verizon will likely result in additional transmission sites as cell phone users get comfortable with bringing their TV programs with them. Mobile television seems like an idea whose time has come, much like iPOD music on the go and cell phones themselves. With the completion of the 700 MHz spectrum auction, it will be interesting to see what other video and TV options become available using MediaFLO and competing technologies.
