Feasibility and Design
Site survey/feasibility studies assists in determining what challenges and opportunities exist that either may interfere with or enhance the design and deployment of the wireless broadband network.
Construction and Configuration
Construction of the Wireless Broadband Network will take place in three main phases (Bandwidth, Backbone, Mesh), each conducted in serial order.
Each phase will start with a deployment planning session conducted between PNG, our Affiliate, and the construction contractor.
Construction of each network element will then be conducted by the contractor under the supervision of a PNG Project Manager. Following the completion of the network construction, PNG's network engineering group will then configure and test the network to ensure its readiness for commercial service.
Backhaul (bandwidth connectivity)
For this network, an initial bandwidth feed of 45Mbits (DS3) is recommended. Upon a successful ramp, it is recommended an OC12 (622Mbps) circuit be added to sustain growth. Based on usage averages, an over-subscription ratio of 5:1 for businesses and 12.5:1 for consumers is recommended.
WiMAX Point-to-Multipoint Backbone
WiMAX is a standards-based wireless technology that provides high-throughput broadband connections over long distances. WiMAX can be used for a number of applications, including "last mile" broadband connections, hotspots and cellular backhaul, and high-speed enterprise connectivity for business.
| Typical WiMAX Backbone Performance |
| Range | Under 4 miles | 4-6 miles | Over 6 miles |
| Access Point cost | $25k per carrier-class AP | Same | Same |
| CPE price | $250 | Same | Same |
| Raw Data throughput (20 MHz channel) | 75 Mbit/s | 50 Mbit/s | 17 Mbit/s to 50 Mbit/s (depending on link quality) |

| *Over-subscription rate is 5x for business and 12.5x for residential. Also takes into account overhead (efficiency), which for 802.16 is 85% independent of number of users. |
WiFi Mesh Client-side Network
Following the deployment of the Backhaul and the WiMAX Backbone a client-side WiFi Mesh network will be deployed. It is recommended this portion of the network be deployed in three phases. Launch of each phase should coincide with agreed to subscriber and revenue growth milestones:
1. Phase One - Seed Nodes/Key Zones (Prior to commercial launch)
2. Phase Two - Filler Nodes/Key Zones (30-120 days after commercial launch)
3. Phase Three - Expansion Nodes/Secondary Zones (After meeting key milestones)
Operation and Maintenance
The PNG Network Operations center (NOC) uses the PowerConnect™ Network Management System to provide 24x7 insight into the real-time status of all network elements.
The PowerConnect™ Network Management System provides real-time monitoring and comprehensive, centralized management of mesh networks deployed in an enterprise or a service provider infrastructure. The system features a client/server architecture with an intuitive graphical user interface (GUI) for managing all mesh-wide and individual node settings for security, traffic prioritization, radio behavior, internetworking, and more.
The system's Multi-Mesh™ capability enables an authorized administrator to manage multiple mesh networks from a single screen. These networks can be independent, or integrated with Mesh-Bridge™ to form a single mesh environment with up to 1000 mesh nodes.
Real-time monitoring depicts a graphical view of active connections in the mesh topology, along with a display of mesh/node statistics and event/fault logs. The display can be customized by importing a floor plan, map or drawing to show the physical location of all nodes in the mesh.
