What 4G frequencies are used by operators to deploy very high-speed mobile?

Since November 2012, mobile telephone operators have started rolling out 4G, no contract fibre broadband, and are already offering new offers. But what is 4G? How does it develop? What will it change in our daily life?

4G (Fourth generation)

4G (or Fourth generation) is a new technological advance in mobile telephony, which succeeds 2G and 3G. The second-generation (2G) corresponds to the arrival of the new communication standard for mobile phones: GSM (Global System for Mobile Communication). It improves international voice communications and allows, thanks to the digital circulation of data, the sending of SMS.

The Third Generation (3G) represented by the UMTS standard offers fast speeds ranging from 2 to 42 Mb / s and thus initiates access to the Internet from a mobile, as well as video viewing and video telephony.

4G, under the LTE-Advanced standard, is today a real revolution since it offers a multiplication of speeds thanks to two phenomena. The first consists of making voice calls circulate no longer on the telephone network, but directly on the Internet (voice over IP). Then, the 4G network uses multiplexing (several types of information passing through the same channel), which makes it possible to increase the quantity of information transmitted. 4G is thus defined as very high mobile speed. Note that the 4G standard is already evolving with the 4G LTE Advanced standard, commonly called 4G + and which further increases speed on LTE mobile networks (up to 300 Mbit / s, 500 Mbit / s, or even more).

4G frequencies and licenses in France

ARCEP (Electronic Communications and Postal Regulatory Authority) has allocated two radio frequency bands in France for the development of the 4G network: 800 MHz and 2600 MHz. The allocation of 4G LTE licenses were carried out in September and December 2011, following an auction. 1800 MHz is now also open to all operators throughout France, and 700 MHz also, in certain regions for the moment ...

By obtaining the greatest number of MHz on the two frequency bands, Orange can provide its users with higher reception speeds (150 Mb / s) than Bouygues (115 Mb / s), SFR (115 Mb / s ) and Free Mobile. Please note that these speeds are theoretical since they will vary according to the number of users and their consumption on the bandwidth.

The lower frequencies have the particularity of crossing obstacles with greater ease, thus ensuring better coverage inside buildings. They can also spread over a larger area. Thus, it will be necessary to install fewer 800 MHz antennas to cover the same area. However, this advantage is certainly interesting for the coverage of rural areas, best broadband deals uk no contract, but more restrictive for urban areas. In fact, covering an area with a dense population supposes a high number of connections, which will undoubtedly cause the permanent saturation of the antenna. This is why the 2600 MHz frequency band (with shorter range) was chosen to allow better coverage of large cities.

Faced with growing bandwidth needs, the Government will auction new frequencies at the end of 2015. From the 700 MHz band, these low frequencies will be particularly efficient to cover the territory. The revenues generated by these gold frequencies will be used by the Ministry of Defense.

Likewise, ARCEP authorizes the reuse of the 2100 MHz band for 4G. This band, until now dedicated to 3G, can thus be used to improve or deploy 4G. With VoLTE and the growing need for mobile internet, Bouygues and SFR were currently authorized by ARCEP in June 2017. The other operators are invited by the Authority to do the same.

4G coverage from Orange, SFR, Bouygues and Free Mobile

As of December 1, 38,159 4G sites were authorized (36,368 in mainland France and 1,791 in overseas territories), including 32,815 in service, for very high-speed mobile telephony (4G) all operators combined (mainland + overseas departments). Each operator is developing its 4G network city by city, while keeping the current 3G network. The deployment of 4G supposes the modification of already existing relay antennas (addition of 4G compatible cells and connection to optical fiber) and/or the installation of new 4G antennas. For this, the operators request authorization from the National Association of Frequencies (ANFR).

As of July 1, 2018, the 4G coverage in mainland France announced by the operators was:

  • 98% of the population at Orange with 14,032 LTE devices in service
  • 96% of the population at Bouygues Telecom with 14,592 LTE sites in service
  • 96% of the population at SFR with 14,129 LTE ​​supports in service
  • 90% of the population at Free Mobile with 9,667 LTE supports in service

These figures do not always allow us to understand the reality of deployments. To be more concrete, let's take the example of Orange, which is one of the most advanced operators in the deployment of 4G. In April 2016, Orange mobile very high speed was present in nearly 3,260 cities where 52 million people live. It will take several more years before the 65 million French people and the 37,000 municipalities in France are covered by 4G! At the end of 2018, Orange, SFR, and Bouygues estimate that they will cover 99% of the population with 4G. According to the coverage obligations imposed on operators by ARCEP when the licenses were transferred, now broadband no contract, 99.6% of the population had to be covered by January 17, 2027, at the latest.

Broadband applications such as Internet consultation, video on demand (VoD), payg broadband , compared to Ethernet, SDH technology is more complex; and voice over IP (VoIP) are real incentives for the deployment of OEoF to businesses. This model is called Fiber To The Building. Synchronous Digital Hierarchy (SDH) SDH or Synchronous Digital Hierarchy is a high-speed transmission technology, based on a “ring”. This type of structure provides a different geographical route, ensuring a backup path in the event that the primary path becomes unavailable. The transmission speed is organized in multiples of 155 Megabit / s and can reach 2.5 Gbps. Among the characteristics of this technology, we can note that: SDH equipment is not available to everyone; the granularity of the transmission rates is only suitable for telecommunications operators. The metropolitan network A Metropolitan Area Network (MAN) is a network that covers approximately an urban area. The MAN is an interm...

What is the difference between ADSL, VDSL, and fiber? The ADSL and the VDSL are two technologies that borrow the traditional telephone line to pass the Internet data, no contract broadband , the television stream, and the telephone (VoIP). The first allows speeds of up to 25 megabits / s and the second up to 100 megabits / s. Depending on the equipment installed by the ISP at your telephone exchange (or distributor), you will benefit from one or the other. Please note: these data are only theoretical. The further away you live from the telephone exchange, the lower the actual speed will be. If your building has fiber, opt for optical fiber which offers much better performance and much higher speeds. Be careful, however: with some operators, How do I know the speed at which I can really claim? You should check with each ISP, including indicating your phone number on their website. Do not hesitate to consult our comparator of Internet service ...
