NetAxis Adaptive Coding & Modulation (ACM) Ensuring maximum bandwidth under all weather conditions With QoS guaranteed critical services all the time Increasing capacity Extending reach with lower availability  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 Maximum Bandwidth with minimum power consumption NetAxis Adaptive Coding & Modulation (ACM)  Radio Resource Control (RRC)

NetAxis Adaptive Coding & Modulation (ACM)  ACM Reach Extension Example Case Study of 14 MHz at 15 GHz Link length is now fixed at 30 Km  16QAM availability at 30 Km % What is the 256 QAM availability at 30 Km?  256 QAM at 30 Km is up % of time  Availability just 0.1% lower than 16QAM Capacity doubled!  97 Mbps extended from 15 to 30km  Fall back to 47 Mbps only % time Over 100% length and Capacity increase - no availability compromise

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% NetAxis Less cost per bit - Ability to overbook available capacity NetAxis Advantages over Hybrid Radios
