PMP 450 ADVANTAGES

Characteristic Cambium PMP Implications

Channel Access Scheduled TDD – Deterministic and Scalable regardless of load

Without scheduled TDD, users will complain about availability as subscribers are added.

Latency and QoS

Consistent and Deterministic – critical for voice and video and T1 replacements

Without consistent latency, network users will complain about delays and poor performance.

GPS Synchronization Supported -> Efficient Channel Re-use / Easy Deployment. in Multi-Sector / Multi-Site systems

Unsynchronized systems perform inconsistently and poorly as subscribers are added. Use more channels to serve the same # of users

Throughput and System Capacity

(bits/sec/Hz/sq km)

High ability for frequency reuse. Higher aggregate real user throughput and system capacity for given channel width and available spectrum.

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


GPS SYNCHRONIZATION

• 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


PMP 450: KEY SYSTEM FEATURES

Radio Performance Features Advantage

High-Efficiency Canopy MAC Higher payload capacity and efficient spectrum use

MULTICAST VIRTUAL CIRCUIT

• New feature on PMP 450 enables multicast traffic to be properly prioritized

• Previously multicast packets were transmitted as part of the Broadcast VC (1X)

• If the Multicast VC is enabled, multicast packets can be transmitted downlink at a configurable data rate (1X, 2X, 4X, 6X) on a separate VC.

16

Enabled under Configuration Radio

Multicast Downlink CIR: Guaranteed multicast VC bandwidth,

this includes the repeat count as part of the multicast bandwidth.

This is calculated separately from the Broadcast CIR.


• Complement PMP 450 with VoIP!

• Clean setup with power supply through WAN port for PMP450 and ePMP SM.

• PMP 450 can support a number of different VLAN modes – Transparent Mode - Traffic with and without VLAN tags are

passed through without modification

– 802.1q Tagging - Untagged traffic coming to the SM will be tagged with configured VLAN ID, and the priority (QoS field) of the packet can also be configured

– Q-in-Q – Untagged traffic coming to the SM will be applied with S-TAG and C-TAG (inner and outer tags)

– VLAN Remarking – Incoming VLAN ID can be modified (re-marked) when passing through the PMP network
