1. PMP450 IntroductionDecember, 2011

2. Increase Performance / Protect InvestmentCambium Networks is working onnew products that will protectyour investmentCambium Networks is developing arevolutionary new PMP 450 accesspoint that will provide significantlyhigher network capacity thanexisting PMP 100 and PMP 430systemsSMs you buy today will becompatible with this new accesspointCopyright 2011 Cambium Networks, Inc. All rights reserved. 2 3. Solution: PMP450 Dual Protocol AP Simultaneously talks to both FSK & OFDM SMs using CanopyMAC protocol Dramatically increases overall system capacity No wholesale change-out of SMs required to achieve benefits Intelligently adapts as OFDM loading increases to maximizeperformance OFDM MIMO data rates of up to 90 Mbps peak throughput MIMO subscribers to maximize network capacityCopyright 2011 Cambium Networks, Inc.
