National transposition dates Date of adoption of this EN: 4 July 2003 Date of latest announcement of this EN (doa): 31 October 2003 Date
19、 of latest publication of new National Standard or endorsement of this EN (dop/e): 30 April 2004 Date of withdrawal of any conflicting National Standard (dow): 30 April 2004 Introduction The main field of application of Point-to-Multipoint (P-MP) systems is to provide access to both public and priva
20、te networks (Public Switched Telephone Networks (PSTN), Private Data Networks (PDN). By means of P-MP systems the network service area may be extended to cover both distant and scattered user locations and the systems may be applied to build new access networks covering both urban and rural areas. U
21、sers are offered the full range of services by the particular public or private network. Users have access to these services by means of the various standardized user network interfaces (2 wire loop, new data services and Integrated Services Digital Network (ISDN) ranging from basic rate to n primar
22、y rate). P-MP systems provide standard network interfaces and transparently connect users to the appropriate network node. These systems allow a service to be connected to a number of users ranging from a few to several thousands and over a wide range of distances. P-MP systems are generally configu
23、red as Pre-Assigned Multiple Access (PAMA) radio systems or as Demand Assigned Multiple Access (DAMA) radio systems. The essential features of a typical P-MP radio system are: - efficient use of the radio spectrum; - concentration; - transparency. ETSI ETSI EN 301 021 V1.6.1 (2003-07) 6 Radio is oft
24、en the ideal way of obtaining communications at low cost and almost independent of distance, and over difficult topography. Moreover, a small number of sites are required for these installations, thus facilitating rapid implementation and minimizing maintenance requirements of the systems. Concentra
25、tion means that “m“ users can share “n“ radio channels (m being larger than n), allowing a better use to be made of the available frequency spectrum and at a lower equipment cost. The term “multi-access“ derives from the fact that every user has access to every channel (instead of a fixed assignment
26、 as in most multiplex systems). When a demand arises an available channel (or channels) is allocated to it. When the demand is terminated, the channel is released for other use. Concentration requires the use of distributed intelligent control, which in turn allows many other operation and maintenan
27、ce functions to be added. Transparency means that the network node and the user terminal communicate with each other without being aware of the radio path. Efficient use of the radio spectrum is generally achieved by reusing frequency sets at base stations in a cellular pattern. ETSI ETSI EN 301 021
28、 V1.6.1 (2003-07) 7 1 Scope The present document covers equipment, which may operate in frequency bands that have paired frequencies, which can be used by either equipment employing Frequency Division Duplex (FDD) or Time Division Duplex (TDD) techniques. For use with Time Division Duplex only one f
29、requency of the frequency pair will be used and for the purpose of the present document the tx/rx separation will be zero. The channel spacing is intended to be the same in downlink and uplink directions. This revision extends the scope to cover systems employing basically TDMA multi-access but whic
30、h also allows for additional methods (such as OFDMA) combined with TDMA, to be used to provide another dimension of multiple access. 1.1 Applications The present document specifies the minimum and optional requirements for system parameters of Time Division Multiple Access (TDMA) Point-to-Multipoint
31、 (P-MP) Radio Systems in the terrestrial Fixed Service operating in frequency bands in the range 3 GHz to 11 GHz. The present document covers the following typical Point-to-MultiPoint (P-MP) applications: - voice; - fax; - voice-band data; - telex, related to analogue interfaces; - data up to 64 kbi
32、t/s or beyond with optional interfaces; - ISDN; - digital video; - digital audio, related to digital interfaces. Radio terminals from different manufacturers are not intended to inter-work at radio frequency (i.e. no common air interface). The present document defines the requirements of radio termi
33、nal and radio-relay equipment including the interfaces. The requirements for multiplex, network management and antenna/feeder equipment may be addressed elsewhere. Testing to the present document will be undertaken with the guidance of a generic test methods document EN 301 126-2-1 22, EN 301 126-2-
34、3 23 and EN 301 126-3-2 24. 1.2 Frequencies The present document covers fixed P-MP services operating in the 3,5 GHz, 3,7 GHz and 10,5 GHz bands, having the frequency plans as given in CEPT/ERC Recommendations 14-03 7, 12-08 25, 12-05 8 and in ITU-R Recommendation F.1491 34. 1.3 Access method The pr
35、esent document covers Time Division Multiple Access (TDMA) systems. Optionally, for certain of the system types defined in the present document, other access methods (e.g. Orthogonal Frequency Division Multiple Access (OFDMA) may be used in conjunction with TDMA to provide another dimension of multi
36、ple access. ETSI ETSI EN 301 021 V1.6.1 (2003-07) 8 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
