OK, we don't really want to bring the idea of work into a story about the fun offered by 4G, but the power of 4G is already being harnessed by all sorts of businesses.
For years now, you've heard more about telecommuting and what's called the mobile office. Since 2005, for example, in the United States there's been a 74 percent increase in the number of people who work from home at least one day per month. What's more, 40 percent of Americans have jobs that could be performed at home [source: Telework].
Businesses now rely on wireless. In fact, 96 percent of small businesses use wireless devices, and 63 percent say they couldn't survive without their ubiquitous connections [Source: AT&T].
3G made it a gamble to access files several megabytes in size. Sharing a video, blueprint or normal word processing document turned into a hit-or-miss proposition. On deadline and away from your office Internet connection? How about a palpable sense of panic to go with that timeout error?
4G is a big part of the mobile office equation. Now, graphics, video clips and presentations loaded with all sorts of multimedia are accessible via a smartphone or tablet. Even at hours when network traffic is exceedingly high, you'll still be able to send and receive data reliably, for pleasure and for less fun activities.
