Applications
The present document covers the following typical point-to-multipoint data applications.
• Wide Area Networks;
• Internet data;
• Voice over IP;
• Data.
Frequencies
The present document covers fixed service allocations in the 3 GHz to 11 GHz band. Bands identified by CEPT for P-MP applications between 3 GHz and 11 GHz are:
- 3 410 MHz to 3 600 MHz [5];
- 3 600 MHz to 3 800 MHz [6]; and
- 10,15 GHz to 10,3 GHz paired with 10,5 GHz to 10,65 GHz [7].
Access method
The standard covers DS-CD/TDMA systems.
The dual definition of the access method arises from the particular features of this system, whereby multiple access is available firstly through the code division, which allows multiple carriers within the channel, and then by sequential time allocation to individual users. The multiple carriers are not co-channel, but are offset from each other by up to half the channel spacing, so packet data systems employing DS-CDMA for multiple co-channel bearers are not within the scope of the present document.
Compatibility
There shall be no requirement to operate Central Station (CS) equipment from one manufacturer with Terminal Station (TS) or Repeater Station (RS) equipment from another manufacturer.
