7.1. Hardware setup
The QDBS–Broadband can be configured with a QDBS–Cellular to provide overlay coverage of
Cellular 1x-RTT and Broadband EV-DO Rev. A coverage. The setup consists of two Radio Cases,
QDBS-Cellular and QDBS-Broadband. The two QDBS systems are interconnected to provide
overlay coverage.
7.2. Overlay system setup
1.
Set up the QDBS–Cellular as described in the QDBS-Cellular Hardware Setup Guide.
2.
Set up the QDBS–Broadband as described in Section 5. It is not necessary that the
systems be right next to each other; however, they must be close enough that the Cat
5e Ethernet cable can reach between the two.
3.
Connect one end of the Cat 5e Ethernet cable to the Ethernet switch in the QDBS–
Cellular and connect the other end of the cable to the switch in the QDBS–
Broadband, as shown in (figure x). 13

NOTE: The QDBS–Cellular CDMA channel must be different than the QDBS–
Broadband channel by at least 50 channels to prevent interference.
