27、 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 private networks (Public Switched Telephone Networks (PSTN), Private Data Networks (PDN). By means of P-MP systems the n
28、etwork 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. Users are offered the full range of services by the particular public or private network. Users have access to these
29、 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 x primary rate). P-MP systems provide standard network interfaces and transparently connect users to the appropriate netw
30、ork 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 configured as Pre-Assigned Multiple Access (PAMA) radio systems or as Demand Assigned Multiple Access (DAMA) radio syste
31、ms. The essential features of a typical P-MP radio system are: - efficient use of the radio spectrum: - concentration: - transparency. Radio is often the ideal way of obtaining communications at low cost and almost independent of distance. and over difficult topography. Moreover. a small number of s
32、ites are required for these installations, thus facilitating rapid implementation and minimizing maintenance requirements of the systems. Concentration means that “mu users can share “n“ radio channels (m being larger than n). allowing a better use to be made of the available frequency spectrum and
33、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 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
34、 released for other use. Concentration requires the use of distributed intelligent control, which in turn allows many other operation and maintenance functions to be added. Transparency means that the network node and the user terminal communicate with each other without being aware of the radio pat
35、h. Efficient use of the radio spectrum is generally achieved by reusing frequency sets at base stations in a cellular pattern. 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 D
36、ivision Duplex (FDD) or Time Division Duplex (TDD) techniques. For use with Time Division Duplex only one frequency of the frequency pair will be used and for the purpose of the present document the tdrx separation will be zero. The channel spacing is intended to be the same in downlink and uplink d
37、irections. This revision extends the scope to cover systems employing basically TDMA multi-access but which also allows for additional methods (such as OFDMA) combined with TDMA. to be used to provide another dimension of multiple access. Applications The present document specifies the minimum and o
38、ptional requirements for system parameters of Time Division Multiple Access (TDMA) Point-to-Multipoint (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) applica
39、tions: - voice; - fax: voice-band data: - telex, related to analogue interfaces; - data up to 64 kbit/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 fr
40、equency (i.e. no common air interface). The present document defines the requirements of radio terminal and radio-relay equipment including the interfaces The requirements for multiplex, network management and antenndfeeder equipment may be addressed elsewhere.
