24、ion. 4.1.1 Statement from MINEFI - France While the French Administration does not see any difficulty in participating actively in border coordination with Administrations having a need for additional AGA channels, it does not support that any harmonized measure be taken in this respect since the ne

25、ed expressed by those Administrations are not shared by others, inter alia by the French one. 4.2 Technical issues 4.2.1 Short background information 4.2.1.1 System description TETRA Air-Ground-Air services (TETRA AGA) have been developed to provide TETRA services to air mobiles in response to user

26、needs and according to a mandate issued by the ETSI Board to develop TETRA Release 2. The mandate included the extension of the operating range of TETRA, to provide increased coverage and low cost deployments for applications such as airborne public safety. TETRA Air-Ground-Air services (TETRA AGA)

27、aims to provide the same TETRA services to air mobiles as to land mobiles. These TETRA services include Mobility Management and all normal TETRA V+D services, but do not include TETRA High Speed Data services (TAPS/TEDS). TETRA Air-Ground-Air services (TETRA AGA) are delivered by a TETRA AGA overlay

28、 network. This AGA overlay network consists of slightly modified TETRA V+D base stations serving modified mobile stations. The modifications are mainly related to cell reselection methods caused by the difference in propagation model between land mobile and air mobile path and larger cell sizes. The

29、 requirements for TETRA Air-Ground-Air services are stated in TR 102 021-8 1. 4.2.1.2 Applications TETRA Air-Ground-Air services enable the cost-effective rollout and efficient use of spectrum resources for delivering TETRA services to air mobiles: improved handover; higher operational flying altitu

30、des; fewer cells; fewer frequencies; easier frequency coordination across borders; cross border communication. ETSI ETSI TR 102 459 V1.1.1 (2006-05) 8 4.2.1.3 New technology (if any) TETRA Long Range is expected before the end of 2006. 4.2.1.4 Short market information See annex A. 4.2.1.5 Market siz

31、e, forecasts and timing TETRA networks for emergency services have the need for Air-Ground-Air services supporting airborne applications. The expectation is that there will be only one overlay network per country. The number of air terminals in a network is typically in the tens (20 to 50). Dependin

32、g on the country, this can be equated to around one aircraft per several (2 to 5) thousand square km. Some networks are already offering these services, using network specific implementations such as non harmonized frequencies for AGA and/or using non harmonized techniques for mobility management. T

33、his creates difficulties for cross border cooperation and may also create cross border interference. Others still have to implement their Air-Ground-Air services fully or partially. The faster the harmonized spectrum is available, the more networks will be able to implement a harmonized solution. TE

34、TRA Long Range which is part of TETRA Release 2 is expected to be finalized by end 2006 so it would be ideal if the harmonized spectrum would be available at the same time. TETRA Long Range uses larger cells with a range (radius) of 83 km (see also clause B.1). 4.2.2 Spectrum requirement and justifi

35、cations Using the modified TETRA V+D base stations, the overlay network for Air-Ground-Air services can employ a frequency reuse cluster of seven. For capacity reasons more than one carrier is sometimes needed around major cities and/or airports. Base station cannot always be installed according to

36、the ideal theoretical cell reuse cluster for reasons such as: international/network border situations; environmental, legal or architectural obstructions. These elements cause the need for spare frequencies on top of the basic seven. The current situation with 8 channels, leaving only one spare freq

37、uency is not offering sufficient margin to cope with the above constraints. Having 10 channels would offer three spare frequencies to cope with the above elements. This is still a small margin, but should allow for most practical situations. 4.2.3 Spectrum parameters 4.2.3.1 Radiated power The trans

38、mitter powers for the mobile and base stations are the same as specified in EN 300 392-2 2 for TETRA V+D. 4.2.3.2 Transmitted bandwidth The transmitted bandwidth is 25 kHz as specified in EN 300 392-2 2 for TETRA V+D. 4.2.3.3 Frequency considerations It is expected that most AGA services implementat

39、ions will be possible within 2 10 channels. The current allocation for Emergency Services are structured in a way to allow DMO (both national and international), TMO and AGA (both national and international) services to operate without producing undue interference to each other. To maintain this sit

40、uation it is preferred that additional AGA channels would be in an adjacent frequency range to the already assigned AGA channels. ETSI ETSI TR 102 459 V1.1.1 (2006-05) 9 4.2.3.4 Frequency usage TETRA Air-Ground-Air services (AGA) are fully integrated services for TETRA V+D. The frequency usage will

41、be dependent on the specific local constraints of the network specific implementation (number of major cities, number of airports, number of airborne applications, environment etc.). 4.2.4 Current regulations The frequency band 380 MHz to 400 MHz is covered by ERC/DEC(96)01 3 (harmonized frequency b

42、and designated for the introduction of the digital land mobile system for the emergency services) and a part of the frequency band is also covered by ERC/DEC(01)20 4 and ERC/DEC(01)19 5. 4.2.5 Compatibility issues See annex C. 5 Main conclusions Issues of prominence in consideration of this SRDoc ar

43、e the need for harmonized spectrum and open standards. The new allocation of additional channels would ensure that in the future other countries will follow this planning, making cross-border communication possible. 5.1 Business importance Based on a very urgent need by the emergency services, in so

44、me countries networks delivering TETRA Air-Ground-Air services are already in place. These networks are using network specific implementations like non harmonized frequencies for AGA and/or using non harmonized techniques for mobility management, in addition to the harmonized frequencies available f

45、or AGA. This non harmonized approach creates risks for cross border cooperation and may also create cross border interference. Airborne emergency services from one country may interfere with terrestrial emergency services in another country. Airborne emergency services from one country may also enco

46、unter difficulties in cooperating with airborne or terrestrial emergency services from another country. A harmonized solution using harmonized frequencies is needed to be enable cross border cooperation between emergency services and to protect the terrestrial emergency service users. In this contex

47、t, it should be noted that this is also a goal of the Schengen Treaty. 5.2 Expected timing for products to market The needed features to make optimal AGA services possible in TETRA are expected to be available before the end of 2006. ETSI ETSI TR 102 459 V1.1.1 (2006-05) 105.3 Requested ECC actions

48、ETSI requests the support of the ECC to enable the users to take advantage of the TETRA Air-Ground-Air services around the end of 2006. Specifically this request comprises: Identify a preferred extension of 2 2 channels for AGA, i.e. a supplement of 2 2 channels for countries that require additional

49、 channels for airborne applications. The addition of 2 2 channels for AGA in the frequency range 380 to 385/390 to 395 MHz to ERC/DEC(01)20 4 (as a supplement to the AGA frequencies already available to emergency services), whereby the preferable solution is in the adjacent frequency range 384,750 to 384,800 MHz and 394,750 to 394,800 MHz.
