Insufficient SpectrumCapacity Constrained

Competitive Alternative to Wireline for Some

WIRELESS NETWORKOF THE PRESENT

• Larger cells on average• Some small cells• Some advanced radio methods• Wi-Fi and cellular mostly operate independently• Limited sharing of spectrum with government• Frequencies: current cellular (600 MHz to 2.5 GHz)• Total spectrum used: approximately 1GHz

NETWORK DESIGN:

Balanced Portfolio of Licensed and Unlicensed SpectrumSignificantly Greater Capacity

Competitive Alternative to Wireline for Many

WIRELESS NETWORK OF THE FUTURE

• Smaller cells on average• Many small cells• Many advanced radio methods (smart antennas, etc.)• Wi-Fi and cellular work together in integrated network• Selective sharing of spectrum with government• Frequencies: current cellular bands and higher frequencies, including mmWave• Total spectrum used: many GHz

NETWORK DESIGN:

Macro Cells Will Continue to Provide Coverage

LEGEND:

Wi-Fi Adds Capacity but Only in Subset of Coverage Area

Small Cells at Higher Frequencies for Capacity

Selective, Well-Defined Spectrum Sharing with Some Government Systems

Fueled by Much More Spectrum in Both Licensed and Unlicensed Bands

Mobile Broadband Networks of the Future
