PMP 450 Advantages Characteristic Cambium PMP Implications Channel Access Latency and QoS GPS Synchronization Throughput and System Capacity (bits/sec/hz/sq km) Scheduled TDD Deterministic and Scalable regardless of load Consistent and Deterministic critical for voice and video and T1 replacements Supported -> Efficient Channel Reuse / Easy Deployment. in Multi- Sector / Multi-Site systems High ability for frequency reuse. Higher aggregate real user throughput and system capacity for given channel width and available spectrum. Without scheduled TDD, users will complain about availability as subscribers are added. Without consistent latency, network users will complain about delays and poor performance. Unsynchronized systems perform inconsistently and poorly as subscribers are added. Use more channels to serve the same # of users Competitive systems require more AP towers to be added to meet demand but this adds interference. Select a solution that meets today s needs and supports growth 27

GPS Synchronization A Must For Access AP and SM communication is synchronized (all APs and SMs have controlled alternating communication) reducing self interference All SMs within a network All APs within a cluster All APs on a tower (multiple clusters) All APs on all towers in the network Enables channel re-use and easy to deploy multi-sector, multi tower networks (minimal tower separation) Use the same number of channels to serve a higher number of users 28
