• Additional Wireless Bands
• Increased Data Throughput Capacity Near Tower Site
• Often Additional Sector Antennas within a Wireless

Band

Ongoing Upgrades to LTE Technology:

Enhancing Macro Tower Coverage and Data Throughput

• Increasing data speeds with the addition of 256 QAM symbol

encoding

• Expanding the number of antenna sectors (expanded spectrum

reuse)

• MIMO antennas (multiple polarization, i.e. horizonal, vertical ++)
• Dynamic “smart” beam- forming antennas
• Enhanced co-channel interference rejection decoding algorithms
• Smarter signal detection algorithms device transmitting power

control

• Enhanced narrow band voice encoding techniques reduce

network VoLTE traffic

Improved in-Building Coverage

Affordable Wireless Signal Boosters

• External antenna receives wireless signal and provides

satisfactory in-building LTE performance (similar to outside TV antenna)

• Internal amplifier (or signal re-generating equipment) provides

higher signal within the building

• FCC released WT Docket No. 10-4 on March 23, 2018 to permit

manufacture of affordable, reliable, low-cost, in-building signal amplification equipment installable by homeowners

Major Planning Challenge in Residential Communities

• Augmenting tower and rooftop cells with

small cells in ROW

• 200,000 cell towers nationally today;

millions of small cells coming

• New cells will be placed near users in

buildings, residential neighborhoods and public ROWs

• Additional fiber optic cable will be

required in neighborhoods to backhaul wireless access points

• 5-10 year lifecycle of wireless equipment

is much shorter than that of fiber or mounting structures

Federal RF Exposure Guideline Standards

• National Environmental Policy Act of 1969 (NEPA) requires the Federal

Government to evaluate and set standards

• FCC has been assigned the responsibility to set standards for human

exposure to RF energy emitted by FCC-regulated equipment

• FCC adopted first set of guidelines in 1985
• Current FCC guidelines: OET Bulletin 65 Edition 97-01
• GAO requested in July 2012 (GAO-12-771) that FCC re-examine radiation

impact of closely held cell phones

• Every community has some degree of concern about radiation

15

How Were the Standards Derived?

• Experts and Standards Bodies:

– National Council on Radiation Protection and Measurement – Institute of Electrical and Electronic Engineers (IEEE) – American National Standards Institute (ANSI)

• Comments to the FCC During Rule-Making:

– Environmental Protection Agency (EPA) – Food ands Drug Administration (FDA) – Federal safety and health agencies – Others

5G Technology

• Under development (standards in 2018, possibly wide-scale in 2020)
• Requires much more fiber; business case still emerging
• Goals are high bandwidth (1 Gbps per user) and low latency (10 ms and

down to 1 ms for critical machine-to-machine)

• To support migration of most consumer and business applications to

wireless, including machine-to-machine such as IoT, autonomous vehicles

• One site can flexibly serve many wireless providers through “slicing”
• Capacity on demand; less processing at site
• Architecture and business model widely varying based on local needs
• Fiber backhaul augmented by wireless
• Tiered topology (sometimes mesh)

Emerging 5G Architecture

• Millimeter wave spectrum

requires direct or near line

• f sight

– Radios every two poles and/or equivalent on rooftops – Foliage a huge issue – Indoor and outdoor radios – Widespread fiber
