PMP 450 Planning Guide
Network migration planning
The PMP 450 Series offers current network operators the ability to migrate to PMP 450 for expanded network
capacity and capability. The following sections are provided to aid in establishing a planning framework for
deploying a PMP 450 system.
Example PMP 450 deployment scenario
The following sections detail example network deployment scenarios for the PMP 450 product. This table may be
referenced to begin planning the PMP 450 deployment based on the current network configuration (if applicable).
Definitions of deployment scenario terminology
Table 17 Deployment scenario terminology descriptions
Term Definition
Existing System Release The current running system software release
Existing Number of Sectors The total number of AP sectors co-located in the current system
Existing Modulation
The type of modulation used in the current network. “FSK”
indicates an existing PMP 1x0 series network, and “OFDM”
indicates an existing PMP 430 network.
Existing Frequency Re-use Pattern
The current deployment’s usage of frequency across tower
sectors. For example, in a six AP sector deployment, the
following represents an ABC frequency re-use pattern.
•
Sector 1 (A): 5740
•
Sector 2 (B): 5760
•
Sector 3 (C): 5780
•
Sector 4 (A): 5740
•
Sector 5 (B): 5760
•
Sector 6 (C): 5780
The deployment scenarios define their own customized examples
of frequency re-use patterns.
For multiple AP cluster deployments, see Multiple OFDM Access
Point Clusters on page 1-97
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 (except 900 MHz FSK, which
operate with 8 MHz channel bandwidth). For OFDM (PMP 430)
deployments, the channel size may be 5, 10, or 20 MHz.
