pmp-0047 (June 2013)
Deployment scenario 1 – Replacing PMP 100 Equipment (20 MHz
Channel Bandwidth)
Deployment scenario 1 assumes that the existing network is comprised of PMP 1x0 equipment (i.e. PMP 100, PMP
120, etc.) with the configuration listed below in Table 10. The migration in this scenario results in a complete
replacement of PMP 1x0 series equipment with PMP 450 equipment.
Scenario 1 assumes that neighbouring frequencies are free and that a guard band is not required at the edges of the
spectrum used for transmission.
