SYSTEM CONFIGURATION

2. SYSTEM CONFIGURATIONThis system consists of TRP-[ ]G-[ ] Transmitter-Receiver (Outdoor Unit (ODU)) (see Fig. 2-1) and MDP-[ ]MB-[ ] Modulator-Demodulator (Indoor Unit (IDU)) (see Fig. 2-2 and Fig. 2-3 ). The [ ]GHz (2/4/8/16 x 2 MB) MB digital radio system is used to communicate from 2 to 16 data streams at 2.048 Mbps and/or up to 2 channels 10BASE-T/100BASE-TX LAN signals between two stations. The system block diagrams of 2/4/8/16 x 2 MB systems are shown in Fig. 2-4 and Fig. 2-5.
