ACM with QoS
RRC: ACM is optimally combined with Automatic Transmit Power Control (ATPC) RRC achieves the perfect balance according to user selection between
Maximizing at any time the available link capacity Minimizing at any time interference
ATPC operational modes ATPC emitting the maximum available power per ACM mode ATPC emitting the optimum power per ACM mode for the remote receiver Manual power selection is also possible
RRC algorithm for each link direction is controlled by the transmitter CPU independently Communication channel will exchange info on remote RX level, BER figures, C/N

NetAxis XPIC & Radio Link Aggregation (RLA) –(Roadmap)
XPIC doubles air throughput over same Channel Bandwidth E.g., 1x28 MHz, XPIC, max 375 Mbps net traffic 1+1 XPIC in 1RU unit
RLA combines 2 or more air links into one logical link E.g., 2+0 can achieve gross capacity 800 Mbps Link speeds may be different
Benefits: Higher total capacity of logical link Load balancing among air links Increased availability: When a link fails its traffic will be forwarded to the other link and in case of congestion priority will be given to the high-priority ETH frames
Combining RLA and XPIC enables the most efficient and resilient air link utilization
XPIC saves CAPEX - 100% less frequency bandwidth allocation

Direct correlation between interface and transmission
Additional Ethernet switches overlaying mandatory TDM matrix
No possibility to differentiate TDM services with different QoS requirements
No aggregation, no overbooking on services using TDM connectivity.
Inefficient solution in case of full Ethernet traffic (WiMAX, LTE); could require external switches
MW Hybrid
Service-oriented transmission with no correlation between interface and transmission
Dynamic capacity allocation between TDM, ATM and ETH services
Services are treated according to their QoS requirements even on TDM
Service Overbooking in a multi-technology environment: TDM, ATM, Ethernet
All services over a common layer, any kind of traffic can share a common radio pipe. Radio bandwidth is utilized at 100%

Less cost per bit - Ability to overbook available capacity
