CoverageSolving the coverage problem at line of sight frequencies. 95% customer reach
PerformanceDelivering a total access network performance capable of supporting ubiquitous broadband to the business and home. 10-50 x PMPCostAchieving a total network cost of connection for 25 Mbit/s (full duplex) of $1,000 SME/SOHO/RES
Radiant’s Mesh technology extracts maximum value from spectrum assets
Breakthrough in broadband access
First to market with innovative Mesh wireless architecture
Wireless benefits (no dig) Moves fixed costs to variable costs, Only suitable for certain customers
PMP is unsuitable in high penetration business and residential deployments
Point to Multipoint (PMP) architecture
For universal broadband there aresignificant problems:

Conventional LMDS
Revolutionary new radio architecture
allow customer unit (nodes) to receive and pass on information
use multiple, narrow point to point links
electronically control links over 360 degrees
use same node equipment at trunk connection
form mesh of interconnected nodes using narrow point to point links
Mesh architecture changes the rules for fixed wireless access
Radiant’s solution - Mesh Networks
Breakthrough in broadband access
Coverage and penetrationSolves the coverage problem at line of sight frequenciesAbility to route around obstacles95% customer reach can be obtained at 1% market penetration
High network data capacityDelivering network performance capable of supporting ubiquitous broadband to the business and homeCustomer data rates (payload) of 25Mbit/s symmetric, full duplexAverage capacity of 4 Mbps to 100% of customers simultaneously
Low cost structureMoves more cost from fixed to variableNo “big ticket” base stationsCapex profile linked to revenue

“How do I achieve Coverage before I have Customers?”
Mesh Performance
Greater Spectral Efficiency means more re-use per km2
Less self-interference:
Narrow beam-width and spatial diversity of nodes generates less node-to-node interference
shorter average links means lower transmitted powers More users per square kilometre
Example performance at ~600 subs/km2 using 2 x 112MHz 25Mbit/s peak to all users 5Mbit/s duplex to more than 30% of all users simultaneously >2Mbit/s duplex average to all users simultaneously
Business proposition
Greater market share and more Services through greater bandwidth and performance
Reduced deployment costs, more flexibility with greater management as customer base increases
Overall reduced cost per customer and closely aligned to revenue

Revolutionary new radio architecture
Massive improvement on line of sight problems over existing solutions 95% customer reach
Resilient Architecture Automatic Traffic Re-route
Powerful Network Management and Planning Systems Making Meshes Manageable
Total access network performance up-to 50 times Greater than PMP
More customers in finite spectrum
Uses same node equipment throughout the Mesh (no base stations) Dramatic improvement to operator business case
Mesh architecture changes the rules for fixed wireless access
