Mobile Data Data in North Amer. Usage per Phone 1.3 EB/month in 2015 3.7 GB/month in 2015 22 GB/month in 2021 (Per Cisco VNI, Ericsson Mobility Report, Mobile Experts LLC, etc.)
Wireless-Only CDC Wireless Substitution (Bi-annual, June 2018) 48 million children live in wireless-only households. Renters: 74.4% Poverty: 67.1% Hispanic: 69.1% Ages 25-34: 77.3% Ages 35-44: 65.7%
Wireless-Only NTIA Census Analysis Wireless by Income McHenry, 2016 Wireless by Income < $25k : 29% $25k - < $50k : 24% Smartphone-only Users 14% in CA (per Field Poll, 2016) < $22k : 25%

The Challenges of Deployment
Muni Challenges Realize a “market rate” for use of public property. Need to protect aesthetics & respond to resident concerns. Lack of technical expertise on staff.
Telecom Challenges Increasingly resistant and well-organized resident groups. Non-standardized negotiation profiles and rates. What is “market rate”?
Spectrum-nomics To increase information: Add more spectrum ($$) 𝐼𝑛𝑓𝑜𝑟𝑚𝑎𝑡𝑖𝑜𝑛= 𝑅𝐹 𝑆𝑝𝑒𝑐𝑡𝑟𝑢𝑚 ∗ log 𝑛 1+ 𝑆𝑖𝑔𝑛𝑎𝑙 𝑁𝑜𝑖𝑠𝑒 Shannon-Hartley Information Theorem To increase information: Add more spectrum ($$) Reduce noise (hard to impossible given physics) Improve/increase signal Reduce users/area
Moving Forward Counter the EMF pseudoscience. Human tissue does not demodulate. (Davis, UM) Free-space path loss. Counter the real estate myth. Appraiser’s Journal survey vs. JVSV 2012 MLS study.
Moving Forward Carriers need better aesthetics. Sizing (smaller = better) Cooling (fans = bad) Resiliency (emergency power) IEEE 5G Deployment WG IEEE members need to be a voice of reason in your communities.
