4G: a revolution for your cell phone?
Scheduled for this summer, tender for licenses 4G sound the advent of fourth generation mobile telephony. Will it a revolution for our mobile and how to adapt? While there is still time before his first deployment and flexible packages, brush our still picture of what is supposed to revisit the mobile Internet.
What should you expect from 4G?
His name defines it as the fourth-generation mobile network. It succeeds the 3G (UMTS) and its evolution to 3G + (HSDPA) and 3G + + (HSUPA). 4G can it be divided into two standards: 3.9 G (LTE) and 4G (LTE Advanced).
Compared to current 3G networks, 4G will offer a much higher speed for mobile Internet connection to meet the major development-hungry data services. This flow could reach 1 gigabit / s in stationary and 100 Mbps in motion.
With 4G, Wimax, which is also reappeared. This fixed network is allowed to become mobile. By cons, although the download speed is greater than the 4G with 128 Mbps, it is not considered to 4G.
A date?
If we stick to the time observed during the recent award of a 3G license, we can estimate that the 4G will around 2 years to generate offers from operators licensed. Indeed, Free obtained a 3G license in January 2010 and will not start the deployment of Mobile Free by 2011.
To expedite the process, the State Council and promises to lower the price of 4G licenses if the operators are committed to quickly cover 99.6% of the territory in 4G.
The French government will launch a tender for the distribution of 4G licenses this summer. Free and the three incumbent operators (Orange, Bouygues Telecom and SFR) are vying for two lots of 5 MHz and two 10 MHz.
The larger beaches could go preferably in Orange and SFR have their finances and their solid numbers of subscribers.
Some countries have already begun experiments. Sweden and Norway, Oslo and Stockholm already have since 2009. In France, like 3G, Paris and Lyon should be taken as test cities for the 4G just after the acquisition of licenses.
Flow?
The flow is the parameter that is revolutionizing the telephone from generation to generation. Today's 4G announcement, therefore, a theoretical throughput of 100 Mbit / s download (download to your mobile), the equivalent of a fiber optic Internet connection.
Figures put into perspective with 3G + currently deployed in France and some 42 Mbps theoretical download. In practice, users rarely exceed 7 Mbps
Indeed, the flow available to the user varies. It depends primarily on the performance of the integrated chip for 3G cell phones upscale latest are better optimized.
Similarly, the distance from the antenna or the number of simultaneous users can influence the flow.
Thus, in the district of La Defense business (92), it is difficult to capture correctly 3G + because of too many people using antennas.
Taking for example the SFR antennas, mostly wired 100 Mbps, if 100 people connecting to it, the flow of each will be only 1 Mbps.
By cons, such an antenna in the open field could deliver the maximum throughput allowed by the latest generation 3G phone (Torch BlackBerry, iPhone 4, Nexus S), or roughly 14 Mbits being close to the antenna. The scheme will not evolve for 4G.
Beyond theory, so it will have to wait to observe the actual flows. Ultimately, the user will win, but not as a portion of ADSL (28 Mbps maximum) to the optical fiber (100 Mbps maximum).
The response time!
Another important point: the response time. If we consider that the flow forms a tunnel between the antenna and the smartphone, the response time is the speed at which one of the two protagonists will return a response to a request to another.
Tested on iPhone 3G and iPhone via the application Speedtest Edge, this response time is explicit. He averaged 900 milliseconds on the first generation iPhone, and 550 milliseconds on the 3GS.
A difference that is attributable to the network chip built into every device. In fact, it takes nearly twice as much time to an iPhone Edge for a response to a request for a 3G.
4G and compatible phones should further improve results.
