Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). Executive summary
17、 The ever-increasing take-up of broadband services around the globe has led to an explosion of data carried over mobile networks over the last few years, as users increasingly expect and demand to be able to access high-speed internet services on their own mobile devices wherever they travel. Airlin
18、e passengers represent a small but important sector of the overall mobile market, since many high-value business customers are frequent travellers and would like to be able to connect to the internet, send and receive e-mails, etc. when travelling on continental, as well as long-haul flights. The pr
19、ovision of information and entertainment services is also a popular service enjoyed by both business and private users during flights. Last but not least, the availability of broadband connections to aircraft in flight can provide additional airline information data to supplement the information alr
20、eady available via existing communications channels. Such usage would be limited to non-safety related data streams, which are known in the aviation industry as “non-mandatory ACARS messages“, (see clause 3.2). In order to meet these user demands, a communications link must be established between th
21、e aircraft and the ground which has sufficient capacity to allow for large numbers of passengers to simultaneously access the various services, including streaming video. Up until now, with the exception of two North American service providers, the only means of providing aircraft backhaul has been
22、through the use of satellite links. This has several disadvantages, including limited bandwidth, cost of capacity and round-trip delays. A broadband Direct Air-to-Ground (DA2G) communications solution overcomes these drawbacks and is highly suitable for use over landmasses, including the majority of
23、 European routes. Work has already begun within CEPT to identify spectrum for such an application. Three DA2GC system proposals have been presented to CEPT. One of these proposals is the system described herein. The present document describes a novel broadband DA2G communications system which makes
24、use of adaptive beamforming antennas in order to achieve the desired system performance whilst maintaining lower transmit power levels than would otherwise be necessary. This feature also facilitates co-frequency sharing with other systems by minimising interference into other services and, at the s
25、ame time, reducing the impact of incoming interference on the achievable link performance. For these reasons, the described system has initially been designed to be capable of operating in any 20 MHz block of contiguous TDD spectrum (or 2 x 10 MHz FDD) within the ISM frequency bands around 2,4 GHz a
26、nd/or at 5,8 GHz (currently used for a number of licence-exempt applications). From the point of view of enabling a timely and cost-effective deployment of the system across Europe, it would be preferable if a licence-exempt or lightly licensed regime could be applied. However, the appropriate regul
27、atory framework will depend on the outcome of studies being carried out within the CEPT. ETSI ETSI TR 101 599 V1.1.3 (2012-09) 5For the system described in the present document, the 5,8 GHz band is currently considered as a possible band for an early introduction in CEPT countries, and, more specifi
28、cally, the portion of the band from 5 855 MHz to 5 875 MHz since this upper part of the 5,8 GHz band is not designated for radar use in Europe. (Radar systems operate in the bands immediately below this range, which would present a much more difficult sharing scenario). The scope of the present docu
29、ment is restricted to the aforementioned frequency bands (2,4 GHz and 5,8 GHz), for the reasons stated. Introduction The present document has been developed to support the co-operation between ETSI and the Electronic Communications Committee (ECC) of the European Conference of Post and Telecommunica
30、tions Administrations (CEPT). The present document is intended to provide sufficient information on the design and operational features of the described broadband DA2G communications system to enable due consideration within the relevant CEPT Working Groups and Project Teams and, in particular, to a
31、id in necessary sharing studies in the frequency bands currently under consideration for a new harmonised designation for such systems. Status of pre-approval draft The present document has been developed and approved within TC BRAN, has been subject to an internal enquiry within ERM and is currentl
32、y undergoing further revisions to resolve comments received, prior to submission for final approval by ERM for publication as an ETSI Technical Report.

37、 present document describes a system designed to provide broadband DA2G communications, which may require a change of the present frequency designation / utilisation within CEPT or some changes to the present regulatory framework for the proposed band(s) regarding either intended or unwanted emissio
38、ns. The preferred regulatory approach would be for this system to operate on a non-interference and unprotected basis within the bands 2 400 MHz to 2 483,5 MHz and/or 5 855 MHz to 5 875 MHz. However, it is recognised that there is a high density and large variety of licence-exempt applications alrea
39、dy deployed in the 2,4 GHz band in CEPT countries and a number of important applications (including ITS applications and BFWA) also are deployed or planned in, or adjacent to the 5,8 GHz band. The present document includes, in particular: Market information. Technical information. Regulatory issues.
