The new iPhone 5 is not compatible with the future 4G French, operators circumvent the difficulty and juggle the technical solutions to provide the best possible throughput to users, irrespective of their smartphone.
As iPad3 launched in March, the latest Apple iPhone is not compatible with the 4G standard used by U.S. mobile operators and ignores French operators that use them the frequency bands 800 MHz and 2.6 GHz.
The four mobile operators Bouygues Telecom, Free Mobile, Orange France and SFR in late 2011 bought the 4G frequencies auctioned by the state for $ 3.6 billion.
However, this technology, which will have a flow from their mobile internet equivalent to a fixed line broadband, is that for now being tested in several French cities and commercial offers that are expected in 2013.
"Apple remains focused on the U.S. market," explains Stéphane Dubreuil analyst at Sia-Conseil while stressing that Europe, 4G is "just emerging, and it is not really a selling point for operators".
Indeed, as Orange SFR insist rather on the fact that users of Apple's newest home will benefit from the improvement they made on their 3G network, enabling speeds up to 42 megabits important.
"No disappointment"
Delphine Ernotte Cunci, Executive Director of Orange France and tells the new iPhone 5 offer "to all those who want to enjoy the H +, the first stepping stone to 4G, which cover more than 60% of the French population end of 2012."
SFR same speech which emphasizes that there is "no deception" on the non-compatibility of the new iPhone 5 with 4G technology that is just beginning to unfold.
In addition, the iPhone "will evolve, there will be other models," which will support the European standards of 4G hopefully we at Orange, while acknowledging "not having a schedule" for this ad.
In fact, the next iPhone's interest to be compatible with the European 4G because "its competitors Samsung, HTC and LG will be", explains Mr. Dubreuil.
Pending a possible new iPhone compatible with the frequencies 800 MHz and 2.6 GHz Bouygues Telecom has taken a different path by asking the ARCEP, the telecom authority, permission to reuse the tape for 4G 1800 MHz, used today by Bouygues Telecom, Orange and SFR for 2G, which transmits voice and low-volume data such as SMS.
At his request, ARCEP launched in late July consultation with operators to investigate the provision of the 1800 MHz frequency band for 4G, which is expected to end on 28 September.
"We are quite confident in a positive decision" of ARCEP at our request, assured the CEO of Bouygues Telecom Didier Casas, "because it is the best way to develop mobile broadband as soon as possible in France "said he.
The operator said so technically ready to launch 4G offers in the band 1800 MHz to first half of 2013, especially for owners of new iPhone 5.
Free Mobile also find interest in the case as Bouygues Telecom "has officially said that if he was given permission to operate in the band 4G 1800 he was ready to return a portion of its 1800 fourth frequency operator ".
Unlike the other operators, Free Mobile won a prize in the 2.6 GHz band, but none in the 800 MHz band in the auction.
