Plug fest

The idea of group tests, or more formally known as a Plug fest, is one of several venues used by numerous technology consortiums. The venue is a means for providing vendors the opportunity to address potential ambiguities and to improve the testing scenarios and capabilities in a technology standard.

MIMO vs. (Beam forming + MIMO)

Larger Screen due to higher data rates

Greater coverage perimeter

Less MIMO-B beam overlap = less noise, more de-correlation, higher data rate

Stronger green halo reflecting stronger signal even behind buildings

Closer data packets indicating higher order modulation= higher data rates

MIMO-only Beamforming + MIMO

High data rates

Plug fest Overview

> Plug fest is sponsored by WiMAX Forum to facilitate

and accelerate industry-wide IOT • Includes chipset, infrastructure/BTS and device suppliers

> Nortel participated in the Wave 2 Plugfest events • France May ’07 and Taipei Oct ’07

> Both events have been extremely successful for Nortel• Proof point of Nortel’s focus to deliver MIMO and Wave 2 compliancy• MIMO A & B IOT completed with wide range of devices and chip-sets• Other key features: SISO, Hand-off, 5MHz and 10MHz Channel,

Authentication, Encryption and Network Entry• IOT achieved with Tier 1 suppliers of devices and chipsets• Recognized as preferred BTS supplier by major chip-set and device suppliers

in WiMAX industry

Nortel delivered leadership in IOT through the WiMAX Forum Plug fest
