Smart Antennas: The differentiator

20


1. 8 Separate Antennas working together in TDD format

1. Smart Antenna algorithms alter the phase and amplitude from each antenna

1. Several effects –

High antenna gain (18dB), providing superior coverage and penetration

Industries highest link budget of 168dB

Beamforming and steering

Non line of sight, indoor coverage

Smart Antenna principles

21


Cisco BWX Adaptive BeamformingMobile WiMAX Beamforming Innovation

Beamforming uses antenna array and signal processing techniques to maximize signal strength for subscriber devices

+18 dB

+9 dB

No Beamforming Energy is dispersed across an entire

90° or 120° sector

Gain decreases quickly with distance, degrading performance

Limited coverage. Cells must be tightly spaced for good performance

Inter-cell interference adversely affects frequency reuse

Cisco’s Beamforming Implementation

Sector Antenna

Cisco 8-Element 120°Beamforming Array

Array is recalibrated every 5ms, energy is focused at individual subscribers

Gain remains high over long distances for static CPE , improving performance

Expanded Coverage. Cells can be widely spaced while providing good performance

Inter-cell interference is minimized, allowing maximum frequency reuse

0 dB

MIMO Matrix-A (Space Time Coding) Symbols are sent redundantly in both space and time

Streams are reconstructed using intact symbols at the receiver

Increases link reliability and fading margins (+3 dB)

MIMO Matrix-B (Spatial Multiplexing) Symbols are divided and multiplexed in space

Multipath must exist to prevent signals from becoming coherent and therefore indistinguishable at the receiver

Increases throughput for stationary subscriber devices

3.4-3.7Ghz frequencies.

• Standards based – 802.16e compliant, Wave 2 certified CPE, Profile C

based ASN-GW. Critical to insure compatibility with other vendors

and a robust technical solution for interoperability.

• IP End to End Solution – Cisco is the only vendor who can provide a

complete end to end solution from the subscriber all the way to

applications. Critical to drive revenue producing services to the

customer.
