11. New Products in version 2.4
Airmux-400/50M
Total Throughput of 50Mbps Full Duplex comprises of: up to 16xE1’s/T1’s and ETH
Maintains Airmux-400 radio performance
Traffic is always symmetric
Airmux-400/100M Optimized for IP Backhaul application
Asymmetric Ethernet throughput up to 100 Mbps aggregate
User settings determine the uplink / downlink capacity (from 50% / 50% up to 95% / 5%)
Actual Capacity allocation between uplink and downlink traffic is dynamic and determined automatically according to:
Actual Ethernet traffic load on each direction
Air interface conditions
In case of congestion, the system uses the user settings

12. New Products in version 2.4
Airmux-400/10M Optimized for TDM backhaul
User Throughput comprises of: up to 16xE1’s/T1’s + 10 Mbps
Maintains Airmux-400 radio performance
Traffic is always symmetric
Best price for TDM applications

13. Typical Applications - Wimax Backhaul
Growing demand for higher capacity
Rural expansion and urban leased line replacement will continue to increase
Access
TDM Access segment turning smaller
Strong competition from Point to Multi Point and WiFi systems
Private networks
Video surveillance market is expected to grow from $4.5B in 2007 to $41B by 2013
Growth is stable through the financial crisis (*Based on ABI market research)
