Fixed Radio Systems - Point-to-multipoint equipment - Frequency Division Multiple Access (FDMA) - Point-to-multipoint digital radio systems in frequency bands in the range 3 GHz to 11 GHz
The present document specifies the minimum requirements for system parameters of Frequency Division Multiple
Access (FDMA) Point-to-Multipoint (P-MP) radio systems in the terrestrial Fixed Service (FS) operating in the bands
3 GHz to 11GHz.
The system will provide access to both public and private networks (Public Switched Telephone Network (PSTN),
Public Data Network (PDN), etc.) by means of the various standardized network interfaces (e.g. 2-wire loop, Integrated
Services Digital Network (ISDN) and 2 Mbit/s).
The system may be applied to build access networks by means of a multi cellular architecture, covering urban,
suburban, and regional areas.
The FDMA P-MP system will transmit a Radio Frequency (RF) signal from the customer site to the Central Station
(CS) only utilizing a spectral bandwidth corresponding to that capacity which is requested from and assigned to the
customer by pre-assignment or by Demand Assigned Multiple Access (DAMA). The CS receives from each customer
site a single modulated carrier being processed independently within the CS. Thus the CS is receiving a FDMA signal.
The present document covers the following typical P-MP applications:
The transmission of:
- voice;
- fax;
- voice band data;
- telex;
related to analogue interfaces and:
- 64 Kbit/s;
- ISDN;
- digital video;
- digital audio;
related to digital interfaces.
Further applications like Asynchronous Transport Mode (ATM) may also be provided.
Two classes of systems have been defined in order to take into account the large variety of possible applications due to
access network implementations and type of service to be provided.
The equipment covered by the present document should be designed to be able to meet the network performance
requirements foreseen by ITU-R Recommendations F.696-2 [1] and F.697-2 [2], for medium, local grade or
ITU-R Recommendation F.1189-1 [3] national portion (access or short haul) o (...abbreviated)
