Désolé, Amérique: Vos ondes sans fil sont pleins

Et 12:4 But thou, A propos de Daniel, tiens secrètes ces paroles, et scelle le livre, to the time of the end: Plusieurs courront çà et là, et la connaissance sera augmentée.

Le AMÉRICANO. industrie du téléphone mobile est en marche sur les ondes nécessaires pour fournir des voix, services de télétexte et Internet à ses clients.

Le problème, connue sous le nom “resserrement du spectre,” menace d'augmenter le nombre d'appels rompus, ralentir les vitesses de données et d'élever clients’ prix. Il sera également rogner le numéro de la nation des opérateurs de téléphonie mobile et de créer une fracture financière plus profonde entre les entreprises qui ont la capacité et ceux qui n'en ont pas.

Spectre sans fil — l'infrastructure invisible sur lequel toutes les transmissions sans fil peuvent voyager — est une ressource finie. Lors de, exactement, nous allons frapper le mur fait l'objet d'un intense débat, mais presque tout le monde dans l'industrie reconnaît qu'une crise est à venir.

Le AMÉRICANO. a encore un surplus de spectre légère. Mais au rythme actuel de croissance, l'excédent se transforme en déficit dès l'année prochaine, selon les estimations de la Federal Communications Commission.

“Le trafic réseau augmente,” dit un fonctionnaire au bureau sans fil de la FCC. “[Carriers] peut gérer pour les deux prochaines années, mais la demande va inévitablement dépasser le spectre disponible.”

Comment sommes-nous arrivés ici?

Le numéro un plus grand pilote n'est consommateurs’ soif insatiable pour l'e-mail, applications et notamment la vidéo sur leurs appareils mobiles — n'importe où, à tout moment. Trafic de données mobiles mondial est à peu près doubler chaque année, et continuera de le faire à travers au moins 2016, selon Cisco (CSCO, Fortune 500) Visual Networking Index mobile, étude annuelle la plus complète de l'industrie.

L'iPhone, par exemple, utilise 24 fois que la quantité de spectre comme un téléphone cellulaire à l'ancienne, et l'iPad utilise 122 fois plus, according to the Federal FCC. AT&T says wireless data traffic on its network has grown 20,000% since the iPhone debuted in 2007.

Video and mobile are breaking the Internet

We got into this principally because technology and demand exploded at a rate that nobody had anticipated,” says Rory Altman, director of technology consultancy Altman Vilandrie & Co.

Another catalyst is the way the U.S. government allocated spectrum. The bands that wireless companies hold were broken up into small chunks across various markets, which was helpful in increasing competition in the 1990s.

But the patchwork nature has proven problematic for new technologies like high-speed 4G broadband. Bigger swaths of uninterrupted spectrum provide the larger amounts of bandwidth needed for delivering faster speeds.

One more contributing factor is that TV broadcasters and government agencies like NASA and the Department of Defense hold some of the best spectrumrelatively low-frequency radio waves that can travel long distances and penetrate buildings.

There are also businesses such as Dish Network (DISH, Fortune 500) that have large spectrum allotments but aren’t currently using them. (Dish is exploring its options for either using or selling its spectrum. A group of cable companies with unused spectrum recently struck a $3.6 billion pact to sell their holdings to Verizon in a deal that’s facing heavy regulatory scrutiny.)

The spectrum crunch is not an inherently American problem, but its effects are magnified here, since the United States has an enormous population of connected users. This country serves more than twice as many customers per megahertz of spectrum as the next nearest spectrum-constrained nations, Japan and Mexico.

When spectrum runs short, service degrades sharply: calls get dropped and data speeds slow down.

That’s a nightmare scenario for the wireless carriers. To stave it off, they’re turning over rocks and searching the couch cushions for excess spectrum.

They have tried to limit customersdata usage by putting caps in place, throttling speeds and raising prices. Carriers such as Verizon (VZ, Fortune 500), AT&T (T, Fortune 500), Sprint (S, Fortune 500), T-Mobile, MetroPCS (PCS) and Leap (LEAP) have been spending billions to make more efficient use of the spectrum they do hold and billions more to get their hands on new spectrum. And they have tried to merge with one another to consolidate resources.

The FCC has also been working to free up more spectrum for wireless operators. Congress reached a tentative deal last week, approving voluntary auctions that would let TV broadcastersspectrum licenses be repurposed for wireless broadband use.

But freeing up more spectrum won’t be enough to solve the problem.

There is no one solution that will address all the needs of the wireless industry,” says Dan Hays, a partner at PricewaterhouseCoopers who specializes in telecom issues.

The good news is that there are ways to buy time. Several innovative approaches are in the works, and there’s a decent amount of spectrum out there that could be turned over to the carrierspossession.

The bad news is that none of the fixes are quick, and all are expensive. For the situation to improve, carriers — et, donc, their customerswill have to pay more.

For a while we won’t notice the quality of service changes, but over time as devices get better and use more data, we’ll start to take notice,” Altman says. “Consumers will notice it, and the burden will fall on the carriers to fix it.
