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

Maximizing FDD Performance with Smart Capex

90% of Traditional FDD Macro is QPSK-16QAM

Major Spectral Efficiency Problem!

Airspan can fix this today!

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.

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%
