The document discusses opportunities and challenges for radio spectrum management in Tanzania. It begins with introductions to radio spectrum and spectrum management. It describes Tanzania's approach which involves economic valuation of spectrum, digital migration to free up spectrum, and use of "white space" spectrum. White space refers to unused frequencies that could enable new applications using cognitive radio technology. However, ensuring no interference with existing services and developing necessary databases present challenges. Overall, the document analyzes how Tanzania can maximize benefits from spectrum resources.
The big events relating to local telecommunications facility regulation and how they fit together; history of Section 332; subsequent case law; the FCC's "shot clock" ruling and Supreme Court case; other pieces to the puzzle.
This document discusses the future of wireless telemetry technology and the applicability of licensed versus unlicensed frequency bands. It argues that licensed VHF frequencies between 218-219 MHz will be better suited for wireless telemetry over unlicensed spread spectrum frequencies. VHF waves can reach distances of 10 miles compared to a maximum of 1,500 feet for spread spectrum, and the infrastructure costs for VHF would be much lower. The document also outlines several potential markets for wireless telemetry like utility meter reading, oil and gas monitoring, and mobile asset tracking.
The Federal Communications Commission is considering adopting rules that could limit local governments’ zoning authority and allow wireless-service providers to add facilities to existing buildings, towers, and other structures in public rights-of-way and elsewhere. The wireless industry will likely push the federal agency to adopt rules that will allow them to place and expand facilities with little or no oversight.

Andrew Seybold's Rebuttal to FCC Capacity White PaperAndrew Seybold
In June 2010, the FCC published its second white paper supporting its recommendations in the National Broadband Plan (NBP) submitted to Congress in March of this year. The first white paper detailed the FCC’s ideas related to the cost of building and operating a nationwide public safety Broadband network. I reviewed that document and prepared my own white paper challenging many of the FCC’s assumptions and questioning its findings.
Spectrum scarcity is an emerging issue in wireless communication systems due to the increasing
demand of broadband services like mobile communications, wireless internet access, IoT applications,
among others. The migration of analog TV to digital systems (a.k.a. digital TV switchover) has led to
the release of a significant spectrum share that can be used to support said additional services. Likewise,
TV white spaces emerge as spectral opportunities that can also be explored. Hence, cognitive radio (CR)
presents itself as a feasible approach to efficiently use resources and exploit gaps within the spectrum.
The goal of this paper is to unveil the state of the art revolving around the usage of TV white spaces,
including some of the most important methods developed to exploit such spaces, upcoming opportunities,
challenges for future research projects, and suggestions to improve current models.
This document outlines the key concepts and objectives to be covered in a chapter about wireless communication. It provides a brief history of wireless communication from its beginnings with Hertz, Marconi and early radio through the development of technologies like cellular networks, pagers, and cordless phones. It describes the evolution of wireless communication technologies over time from early radio telegraphy through modern cellular systems that use digital modulation schemes and personal communication systems.
The document discusses issues surrounding regulation of radio frequency (RF) radiation from telecommunications devices like smart meters. It notes that the FCC's exposure limits were last updated in 1996 and the GAO recommends a review.

and compared with software defined radio (SDR). The two types
of cognitive radio are presented and examples on both spectrum
interweave and spectrum underlay cognitive radio antenna systems
are detailed. Reconfigurable filtennas are proposed as communicating
antennas in a MIMO setting for both cases of cognitive
radio. The benefits of resorting to filtennas as well as toMIMO
configuration is shown and discussed herein. The various antenna
examples are designed, tested and compared with each other. Conclusions
are drawn based on the presented results.

This document provides a case study of the fiber optic network project in Kutztown, Pennsylvania. The key points are:
1) Kutztown embarked on an aggressive Fiber To The Home project to provide internet, cable, and phone services after commercial providers declined to upgrade infrastructure in the small town.
2) The project cost $5 million and now serves 25% of the local market. It has helped lower utility costs and spurred commercial competition.
3) Lessons learned include setting different pricing for residential and business customers and considering alternatives to running only fiber optic lines.
4) While the project has been successful, some states have passed laws prohibiting local governments from competing with
This document discusses clearing incumbent television stations from the 700 MHz band to allow public safety agencies access to the 24 MHz of spectrum allocated for their use. There are currently 75 television stations operating on channels 62-65 and 67-69 that prevent access to this spectrum in major urban areas where demand is highest. The document analyzes data showing these stations represent only 5% of total TV stations but their signals impact 14% of households, with 82% of those viewers watching via cable. Therefore, clearing the spectrum would only impact over-the-air viewing for an average of 3% of households. It recommends options for accelerating clearing like requiring digital-only broadcasts or allowing temporary cable-only broadcasts to provide earlier public safety access to this

Wireless broadband relies on a combination of wireless and wired networks. While wireless signals can transmit over the air for short distances, they require a wired network like fiber to transmit signals over longer distances. In rural areas, providing wireless broadband is challenging due to the greater distances between customers and the higher number of cell towers needed for coverage. Limited and fragmented access to radio spectrum also hinders rural wireless broadband deployment.
Cognitive radio is a form of software-defined radio that can be used to address the spectrum crunch by detecting unused spectrum ("spectrum holes") and transmitting on those frequencies without interfering with the licensed users. It works by constantly sensing its operating environment and adapting its transmission parameters, such as frequency band or power level. This allows cognitive radios to opportunistically use vacant spectrum while avoiding occupied bands. Some challenges to the technology include developing specialized hardware, synchronization between devices, and preventing security vulnerabilities or false interference readings.
The FCC has commenced a new rulemaking proceeding to accelerate the deployment of wireless facilities and broadband. The rulemaking may limit local authority to regulate the placement and size of wireless facilities. It also threatens the ability of localities to prevent harm to environmentally and historically sensitive areas. Localities will need to participate in the proceeding to protect their interests from industry efforts to curb local regulatory power. The FCC is considering rules to implement Section 6409, which concerns modifications to existing wireless towers and base stations, and revisions to shot clock rules under Section 332 that impose deadlines for local permitting decisions.
The document discusses cognitive radio and its benefits. It defines cognitive radio as a radio that is aware of its surroundings and adapts intelligently. Cognitive radio provides a framework for devices to dynamically create links by sensing the environment, evaluating options, and implementing the best waveform. This allows for improved spectrum utilization and quality of service. Some applications of cognitive radio include extending mobile networks, emergency radio systems, and multi-technology phones.
Ppt Effects Of Mobile Network Regulations 2nd AttemptInge Scheve
Government regulation of mobile carriers requiring infrastructure in rural areas can reduce digital divides. While early US and Norwegian telecom policies aimed for universal access, Norway's regulations specifying geographic coverage and minimum network speeds led to earlier mobile adoption across its population. In contrast, the US had fewer requirements, allowing urban-focused providers and delaying rural access. Overall, lack of regulatory requirements for high-speed coverage in rural areas risks increasing digital divides.
This document discusses national standards versus local control of wireless siting issues. It provides an overview of the growth of the U.S. wireless industry from 1997 to 2012. It then summarizes the key rounds of national standards that have been established through the Telecommunications Act of 1996, the FCC's 2009 Shot Clock Order, the 2010 National Broadband Plan, the 2011 FCC Rights of Way and Wireless Siting NOI, the 2012 federal collocation statute, and 2013 FCC Guidance. It raises questions about the implications of the FCC's interpretation of the collocation statute and whether it could impact local control, safety, and aesthetics. It concludes by discussing the potential for future FCC rulemaking.
Power line communication uses existing power lines to transmit data signals. It provides a cost-effective solution compared to installing new communication wiring. The document discusses the basic concepts of power line communication, including that different frequencies are used depending on the wiring and applications can have data rates from kilobits per second to megabits per second over short distances. Advances in digital signal processing have allowed new designs to overcome noise issues on power lines using techniques like spread spectrum modulation and error correction coding. Standards still vary globally which limits technical information sharing for these proprietary systems.

LTE & Wi-Fi: Options for Uniting Them for a Better User ExperienceAricent
Most national governments consider the radio spectrum a valuable national resource and heavily regulate its commercial use. Governments typically auction off licenses for the right to transmit over a portion of the spectrum, which can be very expensive. The traditional business model for cellular
carriers is based on access to this licensed business has coalesced worldwide around a single 4th generation (4G) radio technology standard called Long Term Evolution, commonly referred to as LTE.
LTE & Wi-Fi: Options for Uniting Them for a Better User Experience Aricent

Fast DAS FCC Comments Biennial Review(12-5-2016FY)Farzin S Yazdani
The document provides comments to the FCC regarding its 2016 Biennial Review of Telecommunications Regulations. It argues that Section 1.40001 of the FCC's rules, which facilitates infrastructure sharing, should be modified. Specifically, it suggests adding provisions that (1) allow construction to begin immediately after a wireless facility modification request is deemed granted due to a locality's inaction, and (2) mandate transparency in local governments' review of such requests. The comments assert these changes would further the FCC's goal of rapid wireless broadband deployment by removing delays in infrastructure construction and sharing.
Wireless broadband provides high-speed Internet access over a wide area using wireless technology. It can offer speeds comparable to wired networks like DSL or cable. Fixed wireless networks use stationary connections that can support higher speeds than mobile networks. Wireless Internet service providers (WISPs) offer broadband wireless access, though maximum speeds are typically under 100 Mbps due to limitations of wireless technologies. Demand for wireless broadband in the US has increased the need for additional radio spectrum to be allocated for these services.

Abstract
The use of and reliance on mobile devices and
technologies has become a way of almost all facets
of everyday life. To accommodate the growing
demands for wireless services - communications
and various types of high speed data transfers - the
number of base station antennas on cell towers,
rooftops and other structures, and in buildings
continues to increase rapidly. Only a short time ago,
the commercial wireless carriers focused the siting
of base station facilities in communities to provide
an initial footprint of coverage. Today, increases in
call and data traffic (and consumer demands) has
shifted focus to capacity, where supplemental cell
sites and upgrades of early generation equipment
are increasingly being deployed in many markets.
This presentation provides a general overview
of the evolution of wireless technologies in the
U.S., and highlights emerging technologies used
by the major wireless carriers to meet demands.
The roles of lead community agencies (such as
municipal Planning or Zoning Boards) tasked with
conducting “due diligence” reviews of proposed
wireless telecommunications facilities are
discussed, including the elements of interest to
the citizens these agencies represent. In terms of
risk assessment and risk perceptions, health and
safety considerations such as radio frequency (RF)
emissions will be presented, including a summary of
industry and independent research on RF exposure
levels associated with base station facilities. Federal
Laws - and their interplay with local reviews and
decision making - continue to present interesting
challenges to lead agencies and risk communication.

WIRELESS BASE STATIONS
• Approximately 250,000 cell sites in the U.S., including cell towers, antennas on
rooftops, water tanks, utility lines, and other structures (CTIA, 2010).
• Wireless Telecommunications Facilities come in various shapes and sizes and support
1 or more commercial carrier that services a given area.
• “Not Just Voice Anymore”. Increasingly, wireless technology supports numerous
devices that provide infrastructure for making phone calls, sending emails and text
messages, surfing the internet, and downloading data. There are governmental
initiatives for E-911 and wireless broadband. All of this requires additional bandwidth
and capacity in the wireless networks that support these activities.
• Issues / Local Technical Reviews and Permits / Controversies:
° o Siting of new cell towers
» Location / justification of need;
» Planning for more carrier co-location (“if you build it, will they come ?”)
» Visual Impacts
» NEPA reviews (T&E, historic / cultural resources)
» FAA (height; striping / lighting)
° Health & Safety: RF Emissions, Structural Design
° Powers granted to local authorities / municipalities during review and siting
TRENDS IN WIRELESS FACILITIES
• Trend #1: Capacity vs Coverage
° Old 200 ft tower being split into multiple, smaller cells (shorter towers each with
lower power and smaller coverage than original, but collectively more efficient to
handle data and manage capacity)
• Trend #2: Wireless Facility Upgrades / Modifications
° Replacing old equipment with new technology (800 MHZ, 1900 MHZ frequency
bands)
° “4G”, LTE (“5G” by 2018 ?)
° Frequency Spectrum Auctions (600 MHz;700 MHz; 2.5 GHz)
• Trend #3: “More Antennas, Closer to Users”
° Small Cell Sites; Distributed Antenna Systems
° Existing technology used for years indoors (malls, airports) and in dense urban
canyons to provide concentrated outdoor coverage is now wending its way
into suburbia
FEDERAL RULES & REGULATIONS
Federal mandates and FCC directives limit – but do not fully remove – a local authority’s
ability to review and act on an application for a wireless telecommunications facility. Some
significant Federal actions:
• Telecommunications Act (TCA) of 1996. Section 704
• Local governments “shall act on any request for authorization to place, construct, or
modify personal wireless service facilities within a reasonable period of time;”
• Local government denials of applications for personal wireless service facilities “shall
be in writing and supported by substantial evidence contained in a written record;”
• No local government can regulate “on the basis of the environmental effects of radio
frequency emissions to the extent that such facilities comply with the Commission’s
(Federal Communications Commission [FCC]) regulations concerning such emissions”
(including RF emissions and interference);
• Any person adversely affected by a local government’s decision or failure to act may
“commence an action in any court of competent jurisdiction. The court shall hear and
decide such action on an expedited basis.”
• FCC “Shot Clock” Declaratory ruling of 2009. FCC 09-99
• FCC determined that it possessed the authority and broad discretion to define what
constitutes a presumptively “reasonable period of time” for a local zoning authority to
act on a wireless antenna siting application.
• 90/150 Rule: the FCC determined that a presumptively reasonable period of time to
act on a wireless siting application is 90 days for co-location applications and 150 days
for all other applications – i.e., the 90/150 Rule.
• Excluded from the 90/150 day calculation are “incomplete” applications. However, if
an application is incomplete, the municipality must notify the application within 30
days of submission.
• Middle Class Tax Relief and Job Creation Action (TRA) of 2012. Section 6409
• Mandates that state and local governments must approve an eligible facilities request
for the modification of an existing wireless tower or base station that does not
substantially change the physical dimensions of such tower or base station.
• Eligible facilities request means any request for modification of an existing wireless
tower or base station that involves –
(A) collocation of new transmission equipment;
(B) removal of transmission equipment; or
(C) replacement of transmission equipment
and that does not meet FCC’s definition of “substantial change” (e.g., increasing existing
tower height by more than 10%).
• FCC Treatise (October 2014). FCC 14-153. To be adopted
• Further defines “substantial change”, and encourages deployment of small cell sites.
•
• Addresses Right-of-Way siting of antennas and small cells (utility poles), and local
authority’s role in review and permitting.
RADIO FREQUENCY (RF) HEALTH INFORMATION:
• Radio Frequency is a form of non-ionizing radiation. According to the National Cancer
Institute and other organization, radiofrequency energy, unlike ionizing radiation, does
not cause DNA damage in cells, and it has not been found to cause cancer in animals
or to enhance the cancer-causing effects of known chemical carcinogens in animals.
• At a cell site, the total radio frequency (RF) power that can be transmitted from each
transmitting antenna depends on the number of radio channels (transmitters) that
have been authorized by the Federal Communications Commission (FCC) and the
power of each transmitter. INSERT EQUATIONS BELOW OR NEAR HERE
• FCC OET Bulletins (1990’s) describe Maximum Permissible Exposure (MPE) Limits for
General Public and Occupational exposures to RF. Applicable for evaluating wireless
telecommunications facilities. Criteria based on antenna power and frequency. ADD
CHART NEAR HERE
• The FCC’s safety standards were derived from the recommendations of the National
Council on Radiation Protection and Measurements (NCRP) and the Institute of
Electrical and Electronics Engineers (IEEE). The FCC consulted with and obtained
support for the safety standards from the Environmental Protection Agency (EPA),
the Food and Drug Administration (FDA), the Occupational Safety and Health
Administration (OSHA), and the National Institute of Occupational Safety and Health
(NIOSH).

“Measurements made near typical cellular and PCS installations, especially those with
tower-mounted antennas, have shown that ground-level power densities are thousands
of times less than the FCC’s limits for safe exposure. This makes it extremely unlikely that
a member of the general public could be exposed to RF levels in excess of FCC guidelines
due solely to cellular or PCS base station antennas located on towers or monopoles. When
cellular and PCS antennas are mounted at rooftop locations it is possible that a person
could encounter RF levels greater than those typically encountered on the ground. However,
once again, exposures approaching or exceeding the safety guidelines are only likely to be
encountered very close to and directly in front of the antennas.”

• Other technologies that use radio frequency include portable radios, cordless phones,
baby monitors, radio broadcasting, and Wi-Fi and Bluetooth devices.
• STUDIES:
° WHO / International (cell phones) –
° The electromagnetic fields produced by mobile phones are classified by the
International Agency for Research on Cancer (IARC) as possibly carcinogenic
to humans based on limited evidence from human studies [Interphone], limited
evidence from studies of radiofrequency energy and cancer in rodents, and
weak mechanistic evidence (from studies of genotoxicity, effects on immune
system function, gene and protein expression, cell signaling, oxidative stress, and
apoptosis, along with studies of the possible effects of radiofrequency energy on
the blood-brain barrier).
° National Cancer Institute’s (NCI’s) Surveillance, Epidemiology, and End Results
(SEER) Program, which tracks cancer incidence in the United States over time,
found no increase in the incidence of brain or other central nervous system
cancers between 1987 and 2007, despite the dramatic increase in cell phone
use in this country during that time . Similarly, incidence data from Denmark,
Finland, Norway, and Sweden for the period 1974–2008 revealed no increase
in age-adjusted incidence of brain tumors. A 2012 study by NCI researchers,
which compared
WHO will conduct a formal risk assessment of all studied health outcomes from RF fields
exposure by 2016.
WIRELESS FACILITY SITING ISSUES, RISK COMMUNICATION AND PERCEPTIONS
o Increased acceptance / dependence on wireless devices.
o The number of cell phone users has increased rapidly. As of 2010, there were more than
303 million subscribers to cell phone service in the United States, according to the Cellular
Telecommunications and Internet Association. This is a nearly threefold increase from the
110 million users in 2000.
o Real or perceived increase in personal safety with being connected.
o Explosion in consumer use and Federal mandates drive trends in wireless telecommuni-
cations facility proliferation.
o Health studies on wireless facilities generally “negative”, but studies continuing (mainly
on phones and wireless devices).
o But still opposition to wireless telecommunications facilities.
o Opposition based on perceived health issues. Electro-sensitive individuals ?
o Tower on the hill vs. rooftop antennas vs. antenna on utility pole outside bedroom win-
dow. Who favors / opposes which alternative ?
o Opposition for a variety of other reasons that municipal authorities may otherwise ana-
lyze (zoning code compliance, property values, aesthetic impacts). But authorities are losing
ability to do so.
o Based on Federal mandates – and case law to be played out – the local / municipal role
in future wireless facility siting may be increasingly diminished. Wireless carriers are coop-
erative with municipal requests, Site Plan reviews, and permit processes, but have incentives
to avoid substantial changes, work in ROWs, and take on other approaches to avoid time and
cost for municipal reviews (“time is money”).
o Is something missing ? FCC guidance on evaluating exposures from wireless telecommu-
nications facilities (1996) was developed prior to the boom in the use of wireless devices and
the advent and/or widespread use of Bluetooth and Wi-Fi technologies, small cell sites, and
technology upgrades that have been deployed. Is an update or re-evaluation needed given
the changes to the wireless infrastructure that surrounds us ?
