3rd Annual Broadband Wireless World Forum
San Francisco CA
Breakthrough in broadband access
First to market with innovative Mesh wireless architecture
Coverage
Solving the coverage problem at line of sight frequencies.
95% customer reach
Performance
Delivering a total access network performance capable of
supporting ubiquitous broadband to the business and home.
10-50 x PMP
Cost
Achieving a total network cost of connection for
25 Mbit/s (full duplex) of $1,000
Radiant’s Mesh technology extracts
maximum value from spectrum assets
SME/SOHO/RES
Conventional LMDS
Point to Multipoint (PMP) architecture
 Wireless benefits (no dig)
 Moves fixed costs to variable costs,
 Only suitable for certain customers

Coverage/Customer reach
PMP is unsuitable in high penetration
business and residential deployments
Radiant’s solution - Mesh Networks
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
Breakthrough in broadband access
Coverage and penetration
Mass market
Solves the coverage problem at line of sight frequencies
Ability to route around obstacles
95% customer reach can be obtained at 1% market penetration
High network data capacity
Delivering network performance capable of supporting ubiquitous
broadband to the business and home
Customer data rates (payload) of 25Mbit/s symmetric, full duplex
Average capacity of 4 Mbps to 100% of customers simultaneously
Low cost structure
Moves more cost from fixed to variable
No “big ticket” base stations
Capex profile linked to revenue
Network cost of
$1000 for 25Mbit/s

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
