The “first reference publication” date used is the earliest publication date where Qualcomm feels that a set of reasonably complete and consistent specifications were available. Note that the LTE air interface publication date shown is 12/2007, but the core network (EPC) was published 5 mid 2008. A stable ASN.1 code is required for commercial implementation of the standard (LTE R8 ASN.1 was frozen in March 2009).

Rev. B’s Multicarrier Enhances Broadband Experience—Triples Data Rates to All Users 3x Rev. B Multicarrier 14.7 Rev. A Mbps Single Carrier 3.1 3.6 Mbps Mbps 1.1 1.2 0.4 Mbps Mbps Mbps Peak Rate Median Rate Cell Edge Rate Cost-effective software upgrade to multicarrier Source: Peak rates are as defined in standards. The median and cell edge rates are based on Qualcomm simulations, using 8 mixed channel model with Rev. B Phase-II devices supporting 64 QAM

Rev. B’s Multicarrier More Than Doubles Capacity for Bursty Applications Bursty Data Rate Bursty Data Application Multicarrier (3x Rev. A) (e.g. browsing) 3 Single Rev. A carriers Improved User Experience Increased Capacity Data bursts Partially loaded carriers Idle time No. of Users per Carrier Note: Based on lab measurements using realistic traffic models from the web. The average burst download time (over the air) is reduced ~ 66%. The capacity gain depends on the sector load which in this case is typical for a EV-DO Rev. A system. 9
