credit to purchase our products as a result of global credit market conditions, the failure to fund projects under the U.S. broadband
stimulus program, continued delays in 4G license allocation in certain countries; the failure of the products for the 4G market to
develop as anticipated;, Alvarion’s inability to capture market share in the expected growth of the 4G market as anticipated, due to,
among other things, competitive reasons or failure to execute in our sales, marketing or manufacturing objectives; the failure of the
Alvarion’s strategic initiatives to enable Alvarion to more effectively capitalize on market opportunities as anticipated; inability to further
identify, develop and achieve success for new products, services and technologies; increased competition and its effect on pricing,

48Hybrid Automatic Repeat reQuest (HARQ)
• Allows an extensive use of Matrix B to maximize capacity
• Improves performance under interference / fading changes
• Reliable data transmission at PHY level
combined with forward error correction
• Significantly improves each burst detection
probability
• Like ARQ, reduces error rate by
retransmitting error bursts
• Unlike ARQ, stores and combines error
bursts rather than discarding them
Benefits

49Maximum Receive Ratio Combining (MRRC)
• Combining signals from antennas at each frequency
• Enables improved overall gain, especially in multipath environments
• Increases uplink gain
• Reduces imbalance between uplink and downlink power budgets
• Enhanced system gain
• Increased sector coverage and capacity
• Improved business case
