I must admit, I never really saw the point in having TV on my cell phone. That was until Tuesday.

I was one of the lucky people who was able to get to my ticketed-spot on the National Mall to see Barack Obama become the 44th president of the United States. I trekked more than two hours through a sea of people along the streets of Washington, D.C., to make it to the "Silver" gate for a standing-room view of the inauguration. And I withstood the freezing temperatures throughout the rest of the day to watch the historic swearing-in ceremony and the parade that followed.

Like the rest of the 1.5 million or so people on the mall and lining the parade route for the inauguration, I was trying to text message and call family and friends to share the moment. I also tried to access mobile Web sites to get updates on what was happening. And of course, being the reporter I am, I wanted to update my Twitter feed to let others know what I was experiencing.

But for most of the day, I had only spotty service on my AT&T iPhone. I couldn't text or make phone calls at all from the Mall before or during the ceremony. And forget about Twittering or checking Web sites for updates. My sister, who uses a basic Verizon Wireless flip phone, also had trouble sending and receiving text messages during the inauguration ceremony.

The only mobile service that worked flawlessly on Inauguration Day for me was MediaFlo's FloTV service offered through AT&T. MediaFlo had let me borrow a Samsung FloTV phone specifically for the inauguration. And even though the public relations representative who lent me the phone hadn't charged it completely and forgot to give me a charger for the device, which greatly limited how much I could use it, the service itself worked without a hitch.

While I was very happy to be standing on the mall at all, it quickly became apparent that my sister, Amy, and I, were not going to see much from our vantage point. Not only are we both short. I am five foot four inches tall, and Amy is about five foot two inches. But we were also too far away to see anything but a tiny speck on the steps of the Capitol.

Standing between tall people, we were able to catch glimpses of the big JumboTron in our section. At first we watched as various congressional leaders and celebrities took their seats, Oprah and Beyonce, and then Sens. Ted Kennedy and John McCain. But we wanted to know where Obama was. So we tuned into live CNN coverage of the event. And sure enough, Wolf Blitzer narrated President-elect Obama's journey from the White House, where he was having coffee with President Bush, to the Capitol where the ceremony was set to begin.

After the swearing-in ceremony, Amy and I found ourselves on Constitution Avenue right near the Capitol. And we decided to continue braving the cold temperatures to wait for the Obamas to finish lunch and start the motorcade toward the White House. Again, I turned on the FLO TV phone to get updates. We had quickly made friends with the four or five people standing near us, including an MSNBC news crew. None of us thought much of the ambulance that barreled up Independence Avenue toward the Capitol. It wasn't until I tuned into CNN again on the FLO TV phone that we learned that Sen. Kennedy had collapsed at the congressional lunch. We then huddled together in the cold, watching and listening to President Obama's remarks after the lunch. And just before the phone ran out of battery power, we learned the motorcade was set to begin.

How the FLO TV signals got through
So why did AT&T's FLO TV service work so well for me while its regular phone, text, and data service on my iPhone performed poorly? Well, there's a very simple explanation. My iPhone operates over AT&T's regular cell phone network. And the FLO TV service operates over MediaFlo's owned and operated TV broadcast network. MediaFlo, which is owned by wireless chipmaker Qualcomm, has built a mobile TV broadcast network using wireless spectrum that is currently being used to broadcast analog TV signals in Channel 55.

The company has negotiated with broadcasters in certain markets, and is already offering the service in 56 markets. It will offer the service nationwide in February after TV broadcasters stop transmitting in analog and switch solely to digital.

AT&T and Verizon Wireless resell the FLO TV service, which offers between 11 and 13 channels of broadcast and cable TV programming for $15 a month.

Because MediaFlo's mobile TV network is built as a broadcast network, it can handle large volumes of people accessing content at the same time. The live TV channels are broadcast over the wireless spectrum and viewers "tune in" with their handsets. This approach, used in traditional broadcast television and radio, means that video clips are transmitted only once over the network, instead of being replicated and transmitted hundreds or even thousands of times.

By contrast, voice, text, and data services use AT&T's traditional wireless network, which is built for two-way communication. These networks are divided into cells. Users in a given cell share the available bandwidth. The networks are also designed to be "unicast," which means signals are transmitted between a single sender and a single receiver.

So If 500,000 people in the same cell decide to send a text message, access the Web, or make a phone call at the same time, the network becomes congested and delays text messages, drops calls, or refuses Web connectivity.

AT&T and other wireless operators spent millions of dollars upgrading their networks in anticipation of huge crowds for the inauguration. But because there were so many people packed into Washington, D.C., and in particular around the Capitol and National Mall on Tuesday, the traditional cell phone networks still became congested and didn't perform optimally.

Just to give a sense of the amount of traffic traversing the network on Tuesday, John Taylor from Sprint Nextel said that the volume of voice, text, and data traffic on its CDMA network had broken all previous records by 6 a.m. There was a 212 percent increase in traffic volume from 11 a.m. to 12 p.m., just before the inauguration ceremony began.

AT&T's spokesman Mark Siegel said between 11 a.m. and 12 p.m. text messaging volumes increased six-fold on AT&T's network. Mobile Web access was also way up during this period, Siegel said. But he admitted that there were some problems.

"We feel like the network performed great," he said. "Was it perfect? No, there were occasions when people couldn't get through. That really was no surprise given the number of people that were in such a small area."

Surprise or not, I was happy to have the FLO TV phone. And even though I still think $15 a month is too much to spend on top of my already pricey cell phone plan, I would be tempted to consider it. How about you? I'd love to hear reactions from readers. Would events like the inauguration tempt you to spend more money on a broadcast style mobile TV service?

Upgraded wireless networks in D.C. put to the test

by Anne Dujmovic

Beefed-up cell phone networks in Washington, D.C., got their first real test over the holiday weekend--with reports of scattered outages affecting people who attended the pre-inauguration concert at the Lincoln Memorial on Sunday.

According to a story in The Washington Post, Sunday's concert-goers "sent 10 times the volume of wireless calls, text messages, pictures and videos as on the busiest hour of a typical day." Some estimates put the crowd at 400,000.

"The vast majority of calls went through on the first try," Verizon Wireless spokesman John Johnson told the Post. "We'll be making every adjustment we can make. I don't believe there's any critical capacity we can add, but (Sunday) did help us to do some fine-tuning."

The major wireless carriers have updated the capacity of their networks, spending millions of dollars and preparing for months, in anticipation of a strain on the networks during the presidential inauguration festivities. Even so, some congestion was still expected.

"We did experience some mild call-blocking, as was expected, but with the capacity we added and the number of calls we got on the network and the amount of activity, our network worked about as well as we expected," Crystal Davis, a spokeswoman for Sprint Nextel, told the Post.

The Cellular Telecommunications Industry Association has been advising people to choose texting over talking, and to delay sending snapshots. The trade group also suggested those who are meeting up with others should be sure to have a back-up plan. A few million people are expected to crowd the National Mall on Tuesday to see Barack Obama sworn in as the 44th president of the United States.

On Inauguration Day, will my cell phone work?

by Marguerite Reardon
  • 10 comments

When I head to Washington, D.C., this weekend for the 44th president's inauguration, there's one major question burning in my mind: Will my cell phone work?

I am one of the 240,000 people with free tickets attending President-elect Barack Obama's swearing-in ceremony on the steps of the U.S. Capitol next week. And like the other 2 million or so people descending upon Washington, D.C., this weekend for the festivities, I am counting on my cell phone to not only keep me informed of important traffic alerts and happenings around the nation's capital but also to help me meet up with many friends and family I plan to see while in town.

The last presidential inauguration I attended was back in 1993 when Bill Clinton had just taken office. Back then I didn't even know anyone who owned a cell phone. I had to make plans ahead of time, if you can believe that, to make sure I could meet my sister, who had my ticket.

Nowadays, nobody makes plans ahead of time. Instead, we rely on our cell phones to allow us to plan on the fly. I have already exchanged cell phone numbers with at least six different "friends" on Facebook to meet up this weekend. I don't have solid plans with any one of these people. So I am simply crossing my fingers that the cell phone network holds up.

Just to put things in perspective, four years ago just over 200,000 people showed up for George W. Bush's inauguration. About 1 million people were in Times Square in New York City on December 31, 2008, to watch the ball drop. The only other crowd of this size that has assembled in recent times is the yearly Muslim pilgrimage, or Hajj, to Mecca in Saudi Arabia, which this year topped out at between 2 million and 3 million visitors.

While cell phone carriers are constantly upgrading capacity in their networks and have routinely prepared for major events in Washington, D.C., such as inaugurations and state funerals, this will likely be the largest gathering of Americans in one place at one time. And given that most of the 2 million people expected to be in D.C. will be carrying a cell phone, it will certainly put a strain on the network, especially if everyone decides to call, text, Twitter, update Facebook pages, watch live video, or send video clips to friends and family at the same time.

What could make cell phone networks particularly vulnerable this year is the proliferation of new smartphones, like Apple's iPhone or the various Research In Motion BlackBerry phones, that use 2G and 3G networks to access the Web and provide data services.

"We can only bend the laws of physics so much," said Joe Farren, a spokesman for the Cellular Telecommunications Industry Association (CTIA). "If there are 4 million people on the mall streaming video, sending pictures, or calling, there could be congestion."

And network congestion means that cell phone users might experience, dropped calls and delayed text messages. Smartphone users, like me with my Apple iPhone, might also see mobile Web pages load excruciatingly slow or not at all. And for people with video services like Verizon's VCast, Sprint TV, or MobiTV, watching live video of news broadcasts while standing thousands of people deep in the crowd may be impossible.

Best to text instead of talk
The CTIA is advising people to text and not talk. Text messages and e-mails travel through the network much more easily than voice calls, especially during peak traffic times. Users should also snap, and save, and send photos later. Sending pictures via the cell network eats up valuable capacity, so CTIA suggests sharing those special moments later. And finally, the trade group advises all people to have a back-up plan. Think old school, and pick a rendezvous place and time to meet friends and family in case the cell network is so clogged you can't communicate.

That said, the big four wireless operators--AT&T, Verizon Wireless, Sprint Nextel, and T-Mobile USA--say they've spent millions of dollars and months of time increasing capacity on their networks to ensure that their customers have a good experience throughout the inauguration weekend.

Each carrier has deployed Cell On Wheels throughout the city where cell phone usage is expected to be high. And each carrier has already deployed at least one Cell On Light Truck right near the Capitol, where Obama will take the oath of office as the 44th president of the U.S., to boost capacity. These mobile units use satellite and microwave technology to increase the capacity in a cell site. They are often deployed at disaster sites when cell towers have been knocked down or taken offline.

In addition, all four of the major mobile operators have also increased capacity at permanent cell sites throughout the Washington, D.C., area.

All told, AT&T says it has boosted its 3G network capacity along the parade route, where between 300,000 and 350,000 people are expected to be, by 80 percent and its 2G capacity by 69 percent. Sprint Nextel says it has increased capacity on its Nextel iDEN network by about 90 percent and capacity on its Sprint CDMA network by about 40 percent. The other major carriers, Verizon Wireless and T-Mobile USA, have also increased capacity. T-Mobile USA says it has increased capacity at about 100 of its cell sites in D.C.

AT&T also said it has boosted cellular signals in many hotels throughout the city, including the Hilton and Hyatt Regency on Capitol Hill and the Renaissance on M Street. Sprint Nextel also said it has increased service capacity in and around tourist attractions, such as the Smithsonian museums, Union Station, and other places where inaugural balls will take place.

The mobile operators also say they've upgraded what's known as their backhaul networks, which carry wireless traffic from cell phone towers to the wired telephone infrastructure where calls are connected throughout the country and the world.

Operators have also upgraded capacity for emergency first responders. While network congestion may cause problems for regular cell phone subscribers, these first responders will not encounter issues, representatives from the major carriers assured me. Calls by emergency responders such as police, firefighters, and medical crews will be given priority over other wireless traffic. And new interoperability standards among the carriers' networks and devices should eliminate communication issues, such as the ones that occurred during the September 11 attacks on the World Trade Center.

Quality of service will depend on numbers
As for consumers, representatives from the carriers say they feel confident their services will operate with only minor hiccups. But they all agree that the quality of their service ultimately depends on how many people show up in D.C. this weekend. Early estimates pegged the number around 4 million to 5 million people. But more recently, estimates have fallen to between 1 million and 2 million.

"We feel comfortable with all we've done to prepare for this event," said John Taylor, a spokesman for Sprint Nextel. "And our customers will have great service. But if more than 2 million people show up, there will be blocked and dropped calls. And text messages will be delayed. "

Taylor said that even if the crowd stays below the 2 million mark, there could be delays and dropped calls at critical moments during the swearing in ceremony or along the parade route if hundreds of thousands of people send text messages at the exact same moment.

"We saw this happen on New Year's Eve," he said. "The network was flooded with phone calls and messages all at the same time. And some of those messages were delayed a bit."

I'm crossing my fingers that the bitter cold we're experiencing on the East Coast will keep the numbers below 2 million, so that all my wonderful plans for this historic inauguration aren't shattered by crummy cell phone service. If AT&T's network is up and running, I'll be Twittering all weekend on my iPhone. If you want to follow me, check out my feed on Twitter, maggie_reardon.

Verizon workers fired over Obama records breach

by Natalie Weinstein
  • 13 comments

Verizon Wireless has fired the workers tied to the breach of records for a cell phone used by Barack Obama, according to CNN.

A source told CNN on Friday about the firings. The source wouldn't say how many people were involved. The workers had been placed on leave earlier this week during Verizon's internal investigation.

"We now consider this matter closed," the source told CNN.

The breach was publicly reported Thursday; President-elect Obama's transition team was informed a day earlier. Obama's spokesman told CNN that the flip phone, which didn't have e-mail, had been inactive for months.

The source told CNN that the employees weren't authorized to view customer records unless the customer requested it. The employees could not have read text messages or listened to voice mail, CNN reported.
