35、ine; tele-education telephony/voice services (e.g. VoIP) voice-band modems and fax The system could facilitate unicast, multicast, as well as broadcast services. Fixed BWA systems can also be used to provide backhaul links for local area networks (LAN), metropolitan area networks (MAN), and cellular

36、 mobile networks, as well as synchronous digital hierarchy (SDH) rings. 6 Rep. ITU-R F.2086-1 6 Characteristics The following items present some characteristics to deploy BWA systems in the fixed service. The frequency bands to be used may vary in each country; proper band plan and equipment availab

37、ility should be considered to provide reuse of frequency and proper scale for the equipments production. Other characteristics should be considered on deployment of BWA systems, specially to encourage efficient spectrum usage, the quality of service (QoS) provided and the use of new technologies. 6.

38、1 Operating frequency ranges Fixed BWA systems should be operated in a wide frequency range to conform with a variety of bands available in each country. Recommendation ITU-R F.1401 may be used as guidance for consideration of the identification of possible frequency bands for BWA and related sharin

39、g studies. Table 1 provides additional details regarding the frequency bands used in some administrations for wireless access systems (WAS), including BWA and RLANs. A variety of modulation and multiple access techniques can be used by BWA systems. TABLE 1 Example frequency ranges used in some admin

40、istrations for WAS, including BWA and RLANs* Frequency Frequency ranges/bands UHF (300-3 000 MHz) 800/900 MHz 902-928 MHz 1 800/1 900 MHz 2 400-2 483.5 MHz SHF (3-30 GHz) 3.3-3.9 GHz 4.9-5.0 GHz 5.150-5.250 GHz 5.250-5.350 GHz 5.470-5.725 GHz 5.725-5.850 GHz 18 GHz 24/25/28/29 GHz EHF (30-300 GHz) 3

41、2 GHz 38 GHz 40 GHz * These bands are not necessarily allocated by Article 5 in the Radio Regulations (RR)to the fixed service, and may involve, for example, fixed applications in the mobile service. Each BWA system is typically designed to utilize specific channel spacing(s) and channel bandwidth(s

42、) depending on standards utilized or individual manufacturer designs. Different BWA systems, however, can be designed with different channel spacings and for deployments with various base station sectorizations to support efficient use of the spectrum within the available licensed frequency bands or

43、 blocks. For radio-frequency arrangements for fixed wireless access (FWA) including BWA systems, other ITU-R Recommendations (e.g. Recommendation ITU-R F.746) may also be used as guidance. Rep. ITU-R F.2086-1 7 6.2 Spectrum utilization efficiency Information on spectrum utilization efficiency (SUE),

44、 including general criteria for evaluation and comparison of spectrum efficiencies can be found in Recommendation ITU-R SM.1046. Studies undertaken by Radiocommunication Study Group (SG) 1 and mentioned in Recommendation ITU-R SM.1046 indicate that SUE should be measured in terms of ratio of the amo

45、unt of information transferred over a distance to the spectrum utilization factor. Factors that determine the efficient use of spectrum include the isolation obtained from antenna directivity, geographical spacing, frequency sharing, or orthogonal frequency use and time-sharing or time division. One

46、 of the factors which decide the occupied bandwidth1is the characteristics of spectrum shaping/filtering. The equipment should be able to efficiently use the spectrum, with almost no degradation in capacity when co-locating access points and using adjacent channels. To achieve the above, when differ

47、ent operators are assigned to use adjacent channels or adjacent blocks, a certain guardband from the boundary frequency is required. Such an approach has the effect of regulating the carrier separation BW that can be used in each licensed band and requiring that they are the same for all licensed ba

48、nds. An example of the required carrier separation from the boundary frequency for P-MP systems are as follows. In Fig. 1, the centre frequency of the transmitted carriers should have the required separation in frequency BW from the boundary of the adjacent frequency block, which is assigned to a di

49、fferent operator. For this example, BW is defined as below: BW = 1.25 BW0where BW0is the nearest frequency from the centre, at which the relative level of the measured spectrum becomes 23 dB lower than the maximum spectrum level. In principle, the operator should use, within their assigned block, the radio channels closer to the frequency block centre with higher priority. In multicarrier systems, the above requirements should apply to the most outer carri
