New smartphones crave data – Tribune de Genève

In addition to a multitude of connected bracelets, visitors to the Mobile World Congress (MWC), which ended Thursday, March 5th in Barcelona, ​​have been able to enjoy the latest in smartphones.

Each year in preparation for the spring, the Catalan capital sees through the latest creations of the leading smartphone manufacturers, Apple excepted. This year, Samsung, LG, HTC, Sony and Microsoft have especially focused on speed, screen resolution, and the use of noble materials.

Now, devices high-end screen a standard definition of 2560 x 1440 pixels. For tablets, 4K was invited there with 3840 x 2160 pixels. Photo hand, the latest generation of sensors have a definition of 20 Megapixels and can shoot in 4K.

If the screens and gaining clarity and can display every detail, the technologies to the base this evolution they require an increased computing power, more powerful batteries and especially a larger amount of data. These devices are straining mobile networks of telephone operators.

Content highly appreciated videos

According to a study by the Swedish equipment manufacturer Ericsson, smartphones with a screen resolution of 480 x 800 pixels consumed 500 Megabytes of data per month. Owners of newer devices, with a resolution of 1920 x 1080 pixels (Full HD) require them 8 times over 2 Gigabytes (GB).

The thirst for mobile devices data also increases because their users now prefer viewing content reading. The time at which subscribers to Facebook, for example, sending short messages is now over. Sharing with friends is preferably in the form of videos. Thus, the social network founded by Mark Zuckerberg generates no less than 20% of world traffic data, followed by YouTube, Instagram and Snapchat.

In Switzerland alone, the live TV services like Zattoo or Swisscom TV air are among the biggest consumers. These TV offerings including the ability to view content offline for seven days are popular with consumers. Overall, the video content are the source of the strong customer growth in data volumes, says Therese Wenger, spokesperson of Orange.

About his counterpart also confirms that Swisscom Olaf Schulz: Swisscom Mobile customers also consume more and more data. When in October 2013 the average consumption was 1.2 GB, it is passed to subscribers’ Natel Infinity “to more than 2.5 GB. For young people, the amount is even greater.

Technical Issues

And the data Thirst is not close to being quenched. Ericsson estimates that by 2020, mobile devices will consume five times more than at present, 6.5 GB per month. For the time in Switzerland, the demand for dual material each year.

If this trend means pleasing at first sight for operators, it also poses technical problems in network expansion mobile. This thirst data can not be soothed only by the technical progress. Swisscom, Orange and Sunrise are constantly improving the network such as the adoption of 4G standard offering a rate of 300 Mbit per second.

“Every year, we invest a three-digit amount million francs in the expansion of the mobile network, “says Swisscom. Orange and accurate for his part that the technical development benefits all of the customers that the latter has a monthly plan or a prepaid subscription.

New transmitters required

Taking advantage of new technologies, networks earn not only fast but also effective. Compared to the old GSM, LTE can pass more than 50 times more data. However, this thirst data also requires new issuers. A conclusion also comes a Federal Council report on the mobile networks of the future.

While some technical tricks, such as micro-cells or integration of WLAN wireless networks allow to meet the growing needs. But in the end, operators will need either new sites for their transmission antennas or increase the power of existing ones. This map, published on the Confederation website, gives an idea of ​​the network density. (ats / Newsnet)
