IPhone speed, the troubles also linked to the 3G system

Dozens and dozens of complaints from all over the planet: interrupted calls, poor download speeds and Web browsing, low signal strength even in areas well served by 3G, disconnections from 3G to switch to the slower EDGE. The classic lawsuit against Apple for misleading advertising also started in the United States. To shed light on iPhone problems, the Web section of the historic Wired has launched an investigation among all iPhone 3G users on the planet: a questionnaire to be filled out in which to communicate the performance obtained with your smartphone. The research was attended by about 2600 iPhone users spread across all countries and concentrated mainly between Europe and the United States, the two main geographic areas affected by the launch of 11 July. The results that Wired also displayed graphically on a world map highlight extremely different performances from country to country and, within a nation, even with significant differences from one city to another. According to Wired, this evidence is sufficient to ascertain that the problems of the iPhone 3G do not depend on the software or on the integrated Infineon radio chipset (these are the two most accredited hypotheses to date) but rather on the quality, diffusion and capacity of the third generation networks installed by the operators mobile.

The result of Wired's investigation is remarkable because it shows, even if not in a completely scientific way, that the performance of the smartphone with the Apple is maximum in the countries with the most mature 3G networks, rather bad in those geographical areas and even entire states in which the newer and less "dense" 3G network. Among the most curious details we mention that Australia the nation that recorded the lowest connection speeds, while the largest number of total absence of the signal belongs to the United States, while Germany and Holland are the two countries that record the speed record. maximum, equal to no less than 2 MB per second approximately. In Italy (few data collected) there are also performances of 1.5 MB per second.

Finally, another important note: in several urban centers where 3G networks are more widespread, the performance of the iPhone 3G often leaves something to be desired. This detection is explained by the fact that the massive presence of iPhone 3G and other 3G devices significantly reduces the overall performance of the network and, ultimately, the performance available for each user connected at that time.

To the same result, that is to say that all the troubles attributed to date to the iPhone depend instead on the networks of the operators, a completely different test, performed in Sweden, which was published on the Goteborgs-Posten website. iPhone 3G was tested inside an armored metal chamber capable of creating an environment absolutely free of disturbing radio waves. Once the iPhone 3G has been positioned with a special SIM for testing, the performance of the terminal in sending and receiving data is checked in the aseptic environment of the laboratory, all in different conditions of use and position. It is a typical test for cellular terminals and that is usually performed by the manufacturers to verify its operation and also for certification: it is actually a very expensive test to perform.

The results obtained by the Apple smartphone were then compared with those recorded by Sony Ericsson P1 and also with those recorded by a Nokia N73. Well from the direct comparison of the three, iPhone 3G comes out with its head held high: the differences with the terminals of the two historic manufacturers and iPhone 3G are minimal, with performances completely comparable to the other two.

The evidence in the Swedish laboratory is even more significant than Wired's investigation which, although involving a significant number of users, appears to be limited to only a small slice of the total iPhone 3G sold by Apple. The good news for the revolutionary iPhone in its 3G version: now it seems that the cards have returned to its favor by exonerating the hardware and also the software. As for users, the news is less good: if the performance of the iPhone 3G and even its troubles depend mainly on the operators' infrastructures and 3G networks, an update from Apple certainly cannot improve the situation. Things can change significantly only with investments, expansions and expansion of 3G networks.
