L Band (1427-1518 MHz)


The first commercial mobile networks operated in the low frequencies below 1 GHz and the high frequencies in the vicinity of 2 GHz. Later on, they started to use the 2.6 GHz part of the spectrum and now they are at 3.5 GHz. With the European harmonisation of the 1452-1492 MHz band and, shortly, of the 1427-1452 MHz and 1492-1518 MHz bands, an intermediate opportunity is emerging.
It will be necessary to make these new resources available, in particular to meet the growing needs in data transmission capacity to mobile terminals known as Supplemental Downlinks (SDL), boosted by changes to audiovisual content (video, audio streaming) and software updates to smartphones and tablets. The 1452-1492 MHz band has been harmonised at European level since 2015; at national level, ARCEP, the assignee for this portion of the spectrum, can deliver authorisations. Germany and Italy have already given authorisations to mobile operators in this band. The 1427-1452 MHz and 1492-1518 MHz bands were identified by WRC-15 for mobile broadband networks and the CEPT has already started on the regional harmonisation process for these sub-bands. The Commission is seeking to achieve mandatory European-level harmonisation by 2018-2019.
In France, the 1427 MHz-1452 MHz and 1375-1400 MHz bands are currently connected to, and exploited by, over 1,600 fixed links for commercial and government applications. The 1492-1518 MHz band is used for various government applications.

Proposal 1

ANFR will support European harmonisation of these bands and will embark on the spectrum replanning process at national level with a view to arriving at an appropriate national framework by 2019.

Proposal 3

ANFR will ensure a reorganisation of rights enabling mobile networks to operate across the whole L band, from 1427 to 1518 MHz.

Proposal 5

ANFR will consider and propose changes in the spectrum regulatory framework with a view to providing opportunities for audio PMSE in the 1375-1400 MHz band to be shared with government usages, following on from the reconfiguration of the fixed links now using them.

Proposal 2

ANFR will initiate negotiations between ARCEP and the Ministry of Defence to arrive at an exchange of spectrum use rights between 1375-1400 MHz and 1492-1518 MHz bands.

Proposal 4

ANFR will facilitate the migration of fixed links from the 1375-1400 MHz and 1427-1452 MHz bands to the 6 or 10 GHz bands, and that of other government usages to longer-term bands.
