Term Definition
Existing Ch BW (MHz)
The channel size, or channel bandwidth used in the current
system. For FSK (PMP 1x0 series) deployments, the
channel bandwidth is always 20 MHz. For OFDM (PMP
430) deployments, the channel size may be 5, 10, or 20
MHz.
Existing Total Bandwidth Used (MHz)
The total amount of spectrum, in MHz, which is used by the
existing system.
Existing Aggregate Tower Throughput
(Mbps)
The total amount of throughput, in Mbps, available in the
current network deployment.
Existing Additional Frequencies Available
(MHz)
The number of additional frequencies unused by the current
deployment that are available for usage by PMP 450
equipment.
FINAL: Aggregate Throughput (Mbps)
The aggregate throughput available after upgrading to a PMP
450 network.
Resulting Number of Sectors
The number of sectors configured in the new PMP 450
network installation.
Resulting Modulation
The modulation scheme utilized in the new PMP 450
network installation.
Resulting Frequency Re-use Pattern
The new frequency re-use pattern utilized in the new PMP
450 network installation. Each deployment scenario in this
section includes a custom example of a frequency re-use
plan.
Resulting Ch BW (MHz)
The resulting channel bandwidth configured in the PMP 450
system.
Resulting Total Bandwidth Used (MHz)
The total amount of spectrum which is used by the existing
system.
Resulting Aggregate Tower Throughput
(Mbps)
The aggregate throughput available after upgrading to a PMP
450 network.
Resulting Percentage Increase in Aggregate
Tower Throughput
The amount of increase in tower (all sectors) throughput
after upgrading to a PMP 450 network.
Total Bandwidth Used (During Migration)
(MHz)
The total amount of spectrum (in MHz) used when migrating
to a PMP 450 deployment.
