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

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.
