U.S. Wireless Spectrum Overview
• The FCC regulates the use of radio frequencies within the U.S., assigning usage rights and conditions to
various bands across geographic sub-areas. ITU & WRC regulate internationally. Radio frequency physics
favor lower frequencies for greater signal carrying distance as well as structure & foliage penetration.
• Most non-governmental frequencies are licensed, often via auctions to commercial entities and reserved
exclusively for their use. Cellular (& unlicensed Wi-Fi) dominate mobile connectivity. Microwave &
millimeter wave are commonly used for broadcast, backhaul & PtP. FCC considering additional licensed
bands for commercial/public purposes by reallocating spectrum and at times relocating existing uses.
• A limited amount of unlicensed spectrum is currently available, however more is being considered or
processed for release. 902-928 MHz has been used for consumer and commercial devices since 1993. The
explosion of Wi-Fi is the result of developments in 2.4 & 5 GHz unlicensed bands. Mobile uses and the
emergence of IoT is driving demand for more unlicensed bandwidth & bringing new delivery protocols.
CBRS at 3550-3700 MHz is of special interest as a new shared unlicensed option. The FCC is considering
enabling flexible use of the 3.7-4.2 GHz Band. White spaces wireless will share unlicensed, reallocated
500-700 MHz TV bands reaching to 10 km NLOS now & up to 100 km in the future, outstanding for WRAN.

Wi-Fi Augmented Location Tracking
Wi-Fi Positioning System (WPS, also abbreviated
as WiPS or WFPS) is a geolocation system that
uses the characteristics of nearby Wi-Fi hotspots
and other wireless access points to discover where
a device is located. It is used where satellite
navigation such as GPS is inadequate due to
various causes including multipath and signal
blockage indoors, or where acquiring a satellite fix
would take too long. Such systems include
assisted GPS, urban positioning services through
hotspot databases, and indoor positioning
systems. https://en.wikipedia.org/wiki/Wi-Fi_positioning_system

Next-Gen Wireless Overview & Outlook
Short-Range & Personal Area Networks (PANs)
RFID, Near Field Communications (NFC), Bluetooth, Zigbee, WiGig, LiFi & More
Low-Power Wide-Area Networks (LPWANs)
Long-range IoT/IIoT data collection will be a high device volume, high-growth
opportunity at low data rates requiring using licensed or unlicensed spectrum. All of
these LPWAN variants support health monitoring, smart homes/buildings/cities &
regions, mobile lifestyle, transportation, energy, etc. A number of LPWAN approaches
will play out with IEEE 802.11ah (HaLow) & LoRaWAN likely to dominate, augmented by
cellular data services & use of other LPWANs for select situations.
IEEE 802.11ah - HaLow uses unlicensed 902-928 MHz frequencies, Supports
bulk M2M & IoT/IIoT communications at 100 Kbps to 1 km for up to 8,192 low-
power devices per AP
LoRaWAN - Uses unlicensed 902-928 MHz in North America at 22 Kbps at very
long range (city wide coverage) with deep indoor coverage for IoT/IIoT
Sigfox - Unlicensed 915 MHz (in NA) to 100 bps up to 40 km for broad, low-
speed reach
NB-IoT (or LTE-M2) - Narrowband (NB) cellular for LPWAN to 250 Kbps, Mobile
operators need new equipment to utilize
LTE Cat M1 - Cellular for LPWAN to 1 Mbps, more easily integrates to existing
cellular deployments

Medium earth orbit (MEO) satellites are
located between LEO and GEO satellites
at 6,300 to 12,500 miles. 10-18 are
required for continuous global coverage.
Lower latency (150 ms).
Low earth orbit (LEO) satellites are
closest to users (300-1200 miles) but
require 40-70 satellites for full coverage.
Low latency (10 ms).
Geosynchronous (GSO) satellite orbit (22,236
miles) rotates at the same speed as the
Earth’s rotation. Three satellites can provide
global coverage. 300 ms latency, which can
support most applications.
• Geostationary Equatorial Orbit (GEO) is a

coverage) with deep indoor coverage for
IoT/IIoT
• Sigfox - Unlicensed 915 MHz (in NA) to 100
bps up to 40 km for broad, low-speed reach
• NB-IoT (or LTE-M2) - Narrowband (NB)
cellular for LPWAN to 250 Kbps, Mobile
operators need new equipment to utilize
• LTE Cat M1 - Cellular for LPWAN to 1 Mbps,
more easily integrates to existing cellular
deployments
Long-range IoT/IIoT data
collection will be a high device
volume, high-growth
opportunity at low data rates
requiring low-cost
subscriptions, All of these
LPWAN variants support health
monitoring, smart homes/
buildings/cities, mobile lifestyle,
transportation, energy, etc., A
number of LPWAN approaches
will play out with IEEE 802.11ah
(HaLow) & LoRaWAN likely to
dominate augmented by cellular
data services & use of other
LPWANs for select situations,
