1. PMP450 Introduction
December, 2011

2. Increase Performance / Protect Investment
Cambium Networks is working on
new products that will protect
your investment
Cambium Networks is developing a
revolutionary new PMP 450 access
point that will provide significantly
higher network capacity than
existing PMP 100 and PMP 430
systems
SMs you buy today will be
compatible with this new access
point

3. Solution: PMP450 Dual Protocol AP
• Simultaneously talks to both FSK & OFDM SMs using Canopy
MAC protocol
• Dramatically increases overall system capacity
• No wholesale change-out of SMs required to achieve benefits
• Intelligently adapts as OFDM loading increases to maximize
performance
• OFDM MIMO data rates of up to 90 Mbps peak throughput
• MIMO subscribers to maximize network capacity
