Spectral Efficiency Gain –The Magic of AirDensity / AirSpeed
Most LTE networks operate at 1.2
– 1.6 bits/sec/Hz
Mass deployment of AirDensity / AirSpeed
improves efficiency to 3.6 – 4.4 bits/sec/Hz

8. Maximizing FDD Performance with Smart Capex
90% of Traditional FDD Macro is QPSK-16QAM
Major Spectral Efficiency Problem!
Airspan can fix this today!

25. Airspeed Spectral Efficiency Gains
FDD Layer 76% Increase
in Spectral Efficiency

26. Airspeed Use cases
Operator’s FDD Layer is
decongested allowing better
user experience on both
TDD & FDD layers
4.5X Improvement in DL
29X Improvement in UL

27. FDD Decongestion Improvements

29. Dense Urban
areas
• Airspeed solution for TDD network densification in Dense Urban area. In
combination with Macro sites or as a pure alternative to Macro sites.
• Use of dedicated carrier for Outdoor small cells to mitigate interference and thereby
maximize coverage footprint.
Area of Study

 Existing Macro + China TDD 8T8R infill
 Existing Macro + Airspan Airspeed
Evaluation performed with:

31. Existing Macro + TDD 8T8R infills Existing Macro+ Airspeed infills
RSRP > -100dBm = 99 % RSRP > -100dBm = 99%
Results in Dense Urban area : RSRP coverage
32 Airspeed provide same or better coverage than 5 Macro TDD 8T8R sites (More granular coverage)
RSRP > -90dBm = 85% RSRP > -90dBm = 85%
• Better/Equal Coverage
• CAPEX Savings >80%
