Iphone 3G Tale of Three Networks

The apple iphone 3G could get on to the web utilizing any of 3 methods-three types of wireless networks. Which type you are on tends to make an enormous distinction to your apple iphone encounter; there is absolutely nothing even worse than getting to wait around till the subsequent ice age for many Internet web page to get there whenever you require the info now. Right here there, outlined from slowest to quickest.


AT&T’s EDGE cellular network


Your apple iphone can connect to the data over the same stereo that carry your voice, thanks to AT&T’s EDGE cellular data network. The good part is that it’s almost everywhere; your apple iphone could get online almost anywhere you can make a phone call. The bad news is that EDGE is slow. Dog slow-sometimes dial-up slow. Finding a faster way was Apple’s #1 priority when it designed its second
apple iphone. You can’t be on a phone call while you are online utilizing EDGE, either.

AT&T’s 3G cellular network

For the last several years cell phone firms have quietly been building high-speed cellular data networks-
so-called 3G networks. (3G stands for “third generation.” The ancient analog cell phones were the first generation; EDGE-type networks were the second.) Geeks refer to AT&T’s 3G network standard by its official name: HSDPA, for High-Speed Download Packet Obtain. Baby, when you’re on 3G, the apple iphone is great. Internet pages that take two minutes to appear utilizing EDGE show up in about 20 seconds when you are on 3G. Email downloads much faster, certainly when there are attachments involved. Voice calls sound better, too, even when the signal strength is very low, since the iPhone’s 3G radio can communicate with multiple towers at once.

Oh, and you can talk on the phone and use the web simultaneously, which can be very handy indeed.
3G is not all sunshine and bunnies, however; it has two massive downsides. First: coverage. In a test to serve the most people with the least effort, cell companies always bring 3G services to the big cities first. AT&T’s 3G coverage is available in about 350 U.S. cities, which is a good start. But that still leaves most of the country, including ten entire states, without any 3G coverage at all. Anytime you are outside of the blue chicken pox on the AT&T coverage map, your apple iphone falls back to the old EDGE
speeds.

(3G is a much larger deal, and its installation is much further along, outside the United States.) The second big problem with 3G is that, to receive its signal, a phone’s circuitry uses a lot of power. That’s why the apple iphone 3G gets only half the talk time of the original apple iphone (5 hours instead of 10).

Wi-Fi hot spots Wi-Fi

Known to geeks as 802.11 and to Apple fans as AirPort, is the quickest of all. It’s wireless networking, the same technology that lets laptops the world over get online at high speed in any Wi-Fi hot spot. Hot spots are everywhere these days: in homes, offices, coffee shops (notably Starbucks), hotels, airports, and thousands of other places. Unfortunately, a hot spot is an invisible bubble about 300 feet across; once you wander out of it, you are off the web. So Wi-Fi is for people who are sitting still.
