LTE’s Network Efficiencies

Efficiency of Wireless TechnologiesSpectral Efficiency (bits/Hz per site)

LTE inherently a more efficient technology

Source: AT&T *3GPP

• LTE more efficient than HSPA*

• Improvements in architecture and signaling reduce round-trip latency*

• LTE can co-exist with earlier 3GPP radio technologies, even in adjacent channels*

Fast, Efficient, Certain — Optimal Combination of Mobile Broadband Network Assets

Complementary assets to deliver benefits at a level not available with other combinations• Highly compatible spectrum — 700 MHz, AWS• Common network technology — UMTS, GSM, HSPA+

More capacity than either company could produce alone

Fewer dropped and blocked calls, increased data speeds, more consistent service

Expanded LTE deployment — more than 97% of all Americans

Enhanced 4G capabilities — the fastest LTE holdings based on pairing of the companies’ AWS spectrum

Mobile broadband has becomethe critical enabling

technology for innovation and growth

across a wide range of

industries


Greater Density = Better Performance

31

• Integrated tower grids with compatible technology drives efficiency and adds extra capacity

• Equivalent to several years of cell-site build in most markets

• Allows for more efficient engineering as population and usage trends change

• Improves in-building coverage

• More responsive to clustering around events
