3. Cambium Solution: PMP 450
• 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 over 90 Mbps peak throughput
• MIMO subscribers to maximize network capacity
