HSPA HSPA +
• Enhances broadband experience•Doubles data rates to all users
• Doubles bursty application capacity• Standardized femtocell support
• Doubles data capacity• More than doubles voice capacity• Similar HSPA+ and LTE performance• The natural evolution at a lower cost
• Enhanced performance in 10 MHz• Uplink multicarrier• MIMO support with multicarrier
• Multi band multicarrier—aggregation across bands
HSPA+ R10: 20 MHz Multicarrier• Expands HSPA+ to 20 MHz deployments• Evolution to femtocell networks
HSPA+ R9: Expands 10 MHz Multicarrier
Notes: R8 will reach 42 Mbps by combining 2x2 MIMO and HOM (64QAM) in 5 MHz, or by utilizing HOM (64QAM) and multicarrier in 10 MHz. R9 combines multicarrier and MIMO in 10 MHz to reach 84 Mbps peak rates. Uplink multicarrier double the uplink peak data rate to 23 Mbps in 10 MHz in R9. R10 expands multicarrier to 20 MHz to potentially reach 168 Mbps when using MIMO.

LTE Leverages New Wider Spectrum to Boost Data Capacity in Dense Urban Areas
Best suited to leverage new and wider bandwidths
Available in smaller bandwidths
20 MHz15 MHz1.4MHz 10 MHz5 MHz3 MHz
3G CoverageSeamless 3G service continuity from day one—Evolved 3G ensures similar user experience
LTE relative performance decreases with bandwidth due to higher overhead; 40% overhead in 1.4 MHz vs. 25% in 20 MHz results in 25% better relative performance in 20 MHz vs. 1.4 MHz.
