This allows base stations to better distinguish between user signals and eliminate pilot contamination. Pilot contamination occurs now when pilot sequences are reused in nearby cells, causing interference. With many antennas, base stations can spatially separate pilot signals from different cells. This noncooperative approach could improve spectral efficiency without cell coordination. The paper introduces new techniques to address fundamental issues in multi-user MIMO networks with massive antenna arrays at base stations.
A Review on Cooperative Communication Protocols in Wireless World ijwmn
Future generations of cellular communications requires higher data rates and a more reliable
transmission link with the growth of multimedia services, while keeping satisfactory quality of service, .
MIMO antenna systems have been considered as an efficient approach to address these demands by
offering significant multiplexing and diversity gains over single antenna systems without increasing
bandwidth and power. Although MIMO systems can unfold their huge benefit in cellular base stations,
but they may face limitations when it comes to their deployment in mobile handsets.
To overcome this drawback, relays (fixed or mobile terminals) can cooperate to improve the overall
system performance in cellular networks. Cooperative communications can efficiently combat the severity
of fading and shadowing through the assistance of relays. It has been found that using relays the capacity
and coverage of cellular networks can be extended without increasing mobile transmit power or
demanding extra bandwidth.

A QoS Based MAC Protocol For Wireless Ad-hoc NetworkIJNSA Journal
Multimedia communication over wireless Ad-hoc networks has become the driving technology for many of the important applications, experiencing dramatic market growth and promising revolutionary experiences in personal communication, gaming, entertainment, military, security, environment monitoring, and more. The advances in wireless communications and growth of real-time applications have necessitated the development of wireless networks that can support high Quality of Service (QoS) and power control. A node in an ad hoc network is normally battery operated which poses a huge constraint on the power consumption of such a node. Hence, designing a power efficient MAC protocol for ad hoc wireless networks is a major challenge. In this paper, we propose a CDMA based power controlled medium access protocol for mobile and ad hoc network (MNA). The protocol conserves power and provides QoS guarantees for multimedia traffics. In that network one of the fundamental challenger in MANETs is how to increase the overall network throughputs well as reading the delay while maintaining how energy consumption for packet processing in communication. simulation results shows that the performance of the protocol with increase in traffic while QoS is better in terms of Energy consumption, throughput, & communication delay than existing protocol.

The document recommends that governing boards strengthen their global impact on multinational companies like Volkswagen by collaborating with other countries to enforce needed regulations worldwide, since some company decisions have global implications. If a product has a global impact, then governance of that product should be on a global scale through cooperation between major consuming nations working together to impose important regulations, which could achieve the same effect as global collaboration. This approach of cooperating countries enforcing regulations jointly is suggested in response to the Volkswagen emissions scandal, where different nations are pursuing their own investigations and solutions rather than acting uniformly.

The poem "The Charge of the Light Brigade" by Alfred Tennyson personifies the soldiers and horses through vivid imagery. It describes the famous failed military charge during the Crimean War in 1854 where the British Light Brigade was given miscommunicated orders that led them into an attack against overwhelming Russian forces. Through the eyes of the narrator, the poem portrays the soldiers and horses as unwaveringly carrying out their suicidal mission into the "valley of Death" despite knowing they were being sent to their doom. It creates a sense of tragedy through this personification while also conveying admiration for their courage and commitment to following orders without question.

UMTS–BASED third–generation (3G) cellular network can be seen operating & working in many
of the countries across the globe. The 3G networks offer a substantial increase in the capacity for
data and voice communications compared to the 2G or 2.5G networks. The 3G networks are built on
WCDMA. HSDPA [2] is an updated version of Release 99 versions of the 3G networks, providing
as high as possible downlink speed of 10 Mbps. We will be going to examine 3G network capacity

capacity approximation and network planning purposes. There have been a measurement studies on
3G networks but are mainly focused on the performance of pure data traffic under lightly loaded or

7. Wireless Access And The Transmission Bandwidth
Abstract– The demand for wireless access is permanently growing and the transmission bandwidth
is limited. Higher data rates and signal quality is always desired among the users; therefore a more
efficient use of the frequency resource is needed to fill the user capacity needs. Space Division
Multiple Access (SDMA) is used to increase the capacity given by regular multiple access
techniques (FDMA, TDMA and CDMA) using the user position information to provide access to the
best communication channel based on their spatial location. This paper presents Smart Antenna
techniques applied to SDMA systems as an efficient frequency usage technique.
Key Words – Base station, Beamforming, Code division multiple–access (CDMA), Dynamic
Channel ... Show more content on Helpwriting.net ...
The spectrum is limited, but multiple access techniques allow a large number of mobile users to
share the same allocated spectrum efficiently and use the same bandwidth at the same time without
degrading the existing quality of service.
Sending and receiving simultaneously information to and from the base station is desirable among
wireless communication systems. Equipping these base stations with smart antenna arrays enable
beam steering in contrast to sectorized single antenna systems. This make possible to Base Stations
to send data to specific users on the down–link or to receive directed data on the up–link by reusing
channels within a cell for Mobile Stations (MS), spatially separated by smart antenna arrays.
Cellular system divides the area into cells where mobile units are located and aims to increase the
capacity of the channel with an efficient level of quality of service. Channel access can be achieved
through: Frequency division multiple–access (FDMA), Time division multiple–access (TDMA),
Code division multiple–access (CDMA), and Space Division Multiple access (SDMA). In this paper
we will focus on SDMA systems.
SMART ANTENNAAND SPACE DIVISION MULTIPLE ACCESS HISTORY
Smart antennas were developed by the military but as the cellular phone users grew in the 1980s, the

the proposed site. The Board of County Commissioners, sitting as the Zoning Board of Appeals, has
the authority to approve the zoning variance. The zoning variance will be presented to the Board in
December if the special use permit is approved. Ms. Wallingford–Ingo stated a notion was made in
the recommendation section of staff's review. She stated there is a process that requires a
telecommunications carrier to co–locate on other towers before applying for a new special use
permit for a tower. A telecommunications tower cannot be built in excess of the maximum height
limitation imposed within a specific zone. As a matter of clarification, Mr. Powell has indicated that
they have placed this tower where the County directed them to do so. She had several conversations
over the duration of three to four months with one of Mr. Powell's colleagues relative to the location
of the proposed tower and staff's concerns relative to the placement of such. When the applicant
submitted the special use permit application, the zoning maps indicated the proposed site was in the
A–2 Zone District. Upon review of the application, it was determined that the zone district line on
the digital map, which are not the official zoning maps, was A–3. This is when the height limitation

systems is its backbone so as to enhance the quality of service and maintain the continuous service.
Handoff is an important task in maintaining the continuity of call in cellular systems and its failure
can result in ongoing call termination. So handoffs are necessary for providing an enhanced QoS
(Quality of Service) to users and provide a ubiquitous coverage. In order to successfully implement
the handoff process, the system designers make a proper optimum signal level at which point
handoff will initiate. During the handoff process some parameters like relative signal strength,
relative signal strength with threshold, relative signal strength with hysteresis and relative signal
strength with hysteresis and threshold are to be considered carefully. So this paper shows the brief

Our society is dystopian in that we are being watched by the government. The governments
surveillance ranges from cameras to electronics to even emails. We are told that this constant
surveillance is for our safety and to make it a safe environment for us because their main reason is to
protect us when in fact it may not be their true intentions. Surveillance has been a problem in our
society because people think that there's too much cameras which it's not necessary. People feel like
they are constantly being watched. This increase in surveillance makes us question if the
government is collecting of information for their own good.

Carranza was arrested because he was involved in a drunken driving allegations and a hit and run
crash and was also a twice deported worker from El Salvador. Federal investigators used a a device

In 2007, analyst Gartner reported that ICT sector share about 2% in carbon emissions. It might
appear small at first sight but the overall footprint of the whole ICT sector is expected to double
between 2007 and 2020. Mobile data traffic is going to increase dramatically in the next 5 years and
one of the main reason is increase in mobile video traffic. In developing countries, electricity
connections may not be directly available. So, for example, Vodafone uses extra 1 million gallons of
gas per day to provide power their network. The above example gives us an idea of how the energy
is consumed by the information technology. They are increasing energy costs with larger base
station site densities which leads to increase in energy price. Many companies have decided to
reduce carbon emissions, for example Vodafone has set a target to reduce it CO2 emissions by
approximately 50% by 2020. From an operators perspective, lowering of operating expenditure is
possible with reduce in energy consumption. 3% of world wide energy is used by the Information
and Communication architecture which is causing 2% of world wide CO2 emmission. The main key
reason behind the development of mobile VCE green radio program is to reduce carbon emissions

differing bit rates, each with a greatest determination of 1080p and least length of 20 minutes. A
complete assessment run comprises of 10 runs every feature and determination, each with a length
of time of 1000 s. Amid the runs, the accompanying parameters are measured: the cradled recess in
seconds, the player state, which is either slowing down or playing, the current throughput, and the
utilization proportion of WiFi and cell correspondences in connection to the current throughput. The
application particular parameters, including supported recess and player state, are measured at the
customer, while the system parameters, for example, throughput and utilization proportion, are
measured at the VAN server. To measure the advantage of the calculations, we consider the

Present wireless scenario consists of homogeneous network and heterogeneous networks. In
homogeneous network each base station has similar transmit power level, antenna pattern, receiver
noise floor and similar backhaul connectivity. But this type of network has disadvantage of coverage
hole. In heterogeneous network the macro BSs is collocated with micro, pico and femto cells. This
arrangement increases overall spectral efficiency per unit area (capacity) of the network. Whereas
small cell like micro, pico, femto and relays are used to avoid coverage hole and to provide mobility
to the users. Not only this relays can be used to provide backhaul connectivity, where wire line link
is not possible or are expensive to deploy. As determined by the information theoretic capacity
limits, current cellular systems have evolved to a point where a system with one BS achieves near
optimal performance. Researchers are now moving towards more advanced heterogeneous network
topology which will bring the network more closely to the mobile user leading to further capacity
gains [46–49]. HetNets will significantly improve the spectral efficiency per unit area by utilizing a
diverse set of BSs. 1.4 Elements of Heterogeneous Network Heterogeneous deployment need to use

Enhance the network reliability and reduce the cost efficiency always been a major challenge for the
cellular network operator and there is no magic solution to that demand [14]. With evolution of

[18]. The major backhaul challenges that mobile network operator had to deal with up to 4G
network includes capacity, availability, deployment cost, and long distance reach [16]. But, 5G
network will interconnect billions of new start devices with the numerous use cases and services,
which will support machine–to–machine (M2M) services and Internet of Things (IoT) to the mobile
network [6, 8]. This new smart devices will not only enhance the backhaul capacity requirement, but
it will also add two additional challenges in the backhaul network–(a) ultra–low latency of ~1ms
(round trip) connectivity requirements, and (b) denser small cell deployment. This section describes
the 5G backhaul requirements and potential challenges. A. Capacity It is envisioned that 5G will
interconnect everything to the mobile network wirelessly that can be characterized by the

Many cases have been brought to court and are continuing to be brought that say location tracking
without a warrant should not be allowed. The argument most often used is that it is a violation of the
right to privacy. A warrant is not the only way to obtain these records nor should it be. There are
valid reasons that data can be obtained through other methods. The issue is across many platforms of
digital communication but the most prominent and easiest to explain is with cell phones. The use of
historical location tracking data is not a violation of privacy, in fact there is no right to privacy as
most understand the term.
We are tracked almost constantly as participants of todays interconnected world. Every time we
connect to the internet whether it be using a desktop, laptop, tablet, or smart phone that connection

system available in some General Motors vehicles is capable of tracking and in turn reporting out
locations. The IP address of the device used and the addresses connected to are tracked. If location

Base Station
Antennas/Base Station
A Base station or Antenna act as transmitter and receiver of the signals to connect to the mobile
stations. The strength of the network is also affected by the number of mobile station
communicating with the same base station/cell at a given time and the distance from the antennas.
1) For example, the connecting signal between wireless phone and the base station could drop or
end as person calling from that phone drive into a tunnel or walk into a building because the walls of
the building or tunnel blocks the signal to reach to mobile phone . These locations are referred as
"dead zones," "coverage holes," "dead spots" or "obstructed areas."
2) When many people use a same network at the same time and its capacity is overloaded then the
others trying to connect may not be able to connect and may hear a busy tone
3) A cellular network is a wireless network distributed over land areas called cells, each served by at
least one base station/antenna known as a cell site. In this network each cell uses a different set of
frequency so that no neighbor cell can interrupt other's signal.
4) In a mobile phone network these cells are joined together to provide coverage over large areas,
due to the connectivity of these cells a mobile phone can remain connected to the other while
moving from one place to another. Cellular networks offer a number of features:–

34. Pros & Cons
CELLULAR NETWORKS
Pro 's:
Cost:
Most wireline phone companies charge more than what you 'd pay for most alternatives, and some
are taxed more as well. There are some locations where getting new wired phone service is
prohibitively expensive or even impossible. Long Distance and extra features like Call Waiting are
normally included with alternative phones.
More Features:
Cellular and broadband phones normally include Long Distance, Voice Mail, Caller ID, Call
Forwarding and more, usually at no additional charge. They also have Text Messaging and various
forms of data service which are unavailable with a landline.
Portability:
If you move your home more than average (or if it 's on wheels), your phone and your number can

It does work with some broadband phone systems. Your satellite service can still work without it,
but you will most likely pay an extra charge.
Reliability:
Wired telephone services have come as close to 100% reliable as is practical. Their network has
substantial power backup, redundant circuits and years to get it right. Alternatives are improving but
their networks can vary significantly. Cell sites and other communications nodes have a limited
amount of backup power. In an extended power outage, such as after a hurricane or snowstorm, the
service may not work, leaving you with no service. Corded phones work in power failures. Cable
phones also have a lower level of reliability.
Sound Quality:
Some alternative phones don 't sound the same or as good as a landline. While your alternative
phone may sound fine to you, it may be difficult for others. Also, some broadband phone services
just dump their audio into the Internet resulting in widely varying data travel times giving you
significant sound delays.
Lack of Service:
You may be in a location where there are no wireless broadband alternatives or may have poor
cellular coverage. This might be rectified by adding a 'cell site ' to your home.
Broadband Speeds:
While there are some fairly fast wireless broadband connections, it may be some time before they
will compare to wired or cable connections.

With ever increasing on road traffic and dynamic nature of road conditions an intelligent
transportation system (ITS) is essential. Vehicular ad–hoc networks (VANETS) takes the
responsibility in implementing ITS and is a promising communication scenario for traffic
management and safety. VANETs possess unique characteristics like high mobility of nodes, rapid
change in the neighbor nodes, stringent deadline for authentication, association times, no fixed
infrastructure etc. Though VANETs closely resembles Mobile Ad–hoc Networks traditional security
mechanisms are not suitable. This dissertation aims to describe and analyze the most representative
VANET security developments and propose an efficient implementation focusing on key exchange

You have been hired by a cell tower company to evaluate a plan that will erect cell towers through a
local community. Your job is to locate any historic buildings or sites that might be impacted (placed
next to, or on, or be damaged in some way) by the cell towers. You discover there are 10 buildings
along the route the cell towers will take. How will you go about deciding if these buildings are
historic? What criteria will you use? Why? The question has been raised, if I were hired to evaluate
the plans to erect cell phone towers, and I have discovered that there are ten historic buildings in the
path of the towers, which structures would I deem significant to keep. Many of these homes and

However, using many of the criteria from each federal agency, we can determine which of these
structures must be preserved from the work being performed.
One of the first criteria to determine whether the site is historic is the age of the property. The site
needs to have many other criteria, but many people have determined that the site needs to be more
than fifty years old. This is not the sole requirement for it to be historic because this only means that
the site would have been built in the mid–1960s. However this is the beginning, and must follow
along with some or all of the following criteria to be determined to be a historic site. However
during the later portion of the 1960s and later into the 1970s there were many structures built which
could be deemed significant. However, each of the ten structures will be looked at to see if they
were build more than fifty years ago, unless they have the exception of the next three criteria.
The first criteria of the National Register of Historic Places that I will use to determine if the
structures are historic is whether the site is associated with events that made a very significant
impact and contribution to the patterns of history in the town, county or state where it is located.
This includes sites where individuals that were prominent to important events in history lived at the

41. Cell Phones And Health Risks
During my recent searches on this particular subject, I across interesting studies regarding cell
phones and health risks. Cell phones have changed drastically from 20 years ago to present. When
phones first came out they were only in our homes, I recall when I was younger we would go places
and wouldn't have a cell phone to call or text, to let your family know your location, unlike today. In
the early 90's, the bag phone was introduced to the public. These phones were a big deal when they
first came out, you would plug them into your cigarette lighter. When you would call someone it
took a bit for it to go through but once the call went through you could hear someone on the other
line. When you got done with the call you would hang up and once you got home you would zip the
phone up and carry it inside. As a kid, this was very interesting. The cordless cell phones were
quickly developed. If you had a cordless cell phone you were cool. When the cell phones first came
out, your options were limited. At the time talking was the only option available, more options were
available; text, check email, and facebook. The more technology rise; the more you can do on your
phones, from skype to google and even ask your phone questions and it will answer back. When I
did recent research I found that the studies have become more about what the cell phones are doing
to people and their health. In this essay you will learn that throughout history, Scientists have done

43. Who Is Adnan Syed Innocent
Adnan Syed's Innocence
When one is guilty, it means that he or she is "culpable of or responsible for a specified
wrongdoing" or, "having committed an offense, crime, violation, or wrong, especially against moral
or penal law; justly subject to a certain accusation or penalty." If someone is charged as guilty, they
have broken a law or performed an unjust or immoral act to deserve punishment. However, this does
not mean that through reasonable suspicion that an individual can be determined as guilty. It means
that "a defendant is innocent until proven guilty. In other words, the prosecution must prove, beyond
a reasonable doubt, each essential element of the crime charged." In other words, a particular person
must be proven guilty of a crime through proof and evidence. In the story provided by Serial, Sarah
Koenig narrates the case of the murder of Hae Min Lee. Seventeen years ago, on January 13, Hae
Min Lee, a senior at Woodlawn High School, was reported missing. Weeks later, her body is found
and the cause of her death was determined to be manual strangulation. Her ex–boyfriend, Adnan
Musud Syed, was convicted of her murder and sentenced to life plus thirty years in prison. The case
against him was mainly based on the story of one witness, Jay Wilds. Now, past reporter and
journalist, Sarah Koenig is reopening this case to find out what really happened. Through

Network security is very important on any network with a DSL connection on a fixed line there is
no change in the network security. Network security would be handled by a firewall that would be
handled by the modem and of course at the device itself. Then the subscriber or company would
themselves use additional software for further protection. Troubleshooting is handled by both the
subscriber and Telephone Company. There is a way to determine where one ends and the other
begins this is known as the demarcation line. This is usually where the wiring enters the home or
building. But this really depends on if this is a single occupant property or a multiple occupant
property. The failover solution when using a fixed line service for Internet connection would be to
have back up equipment available for the site and for the Telephone Company it would be good to
know at the central office there is additional servers just in case there is a malfunction. When it

Self–Organizing Networks. This concept was presented during the transitional period from 3G to 4G
technology. During this period mobile communications began to grow rapidly. Self–Organizing
Network functions are separated into three major groups: self–configuration, self–optimization, and
self–healing. Self–configuration allows devices to function properly with a system the instant they
are connected. Self–optimization supports networks by examining the performance of a system and

During this period cellular or mobile communications has begun to rapidly grow. The amount of
time spent on network allocation, concentration, usage, and maintenance for these newer
technologies were starting to become more complicated. The Third Generation Partnership project
(3GPP) and Next Generation Mobile Networks (NGMN) organizations were the first to introduce
the Self–Organizing Network (SON) concept. This new technological automation concept was
specifically designed to make planning, configuring, managing, optimizing, and troubling shooting
networks simpler and more efficient. The first technology to incorporate SON features into its
design was LTE, but SON was also designed to support older technologies such as UMTS. With this
capability base stations would be capable of optimizing specific parameters with complex
algorithms that would observe performance and enhance the network. Self–Organizing Network
Functions SON functions are commonly separated into three major groups, each of which contain a
broad range of algorithmic equations. These groups are commonly referred to as: – Self–

Disadvantages: Despite the benefits that can be achieved by this technique, there are some
challenges that need to be addressed, including management of the interfaces between

ICIC was developed to deal with interference issues at cell–edge and mitigates interference on
traffic channels only in heterogeneous network. These limitations were bypassed with Release 10
specifications which introduced enhanced Inter Cell Interference Coordination (e–ICIC).
Enhancements were brought to deal with interference issues in Heterogeneous Networks and

Amazon has many reports of fraud concerning both buyers and sellers. Since Amazon is only the
company who brings the two parties together, they will investigate but are not liable for fraud. The
ads that Google uses have been unknowingly infected with viruses and malware (Mills, 2010). The
people behind the Google viruses and the Amazon fraud have one goal; to steel your money. With
these sites being accessible on mobile devices, makes it that much easier to acquire. Devices such as
cell phones and laptops can make people lose focus on what they are doing. For example, in the

71. Tracking and Positioning of Mobile Systems in...
ABSTRACT
Mobile positioning technology has become an important area of research, for emergency as well as
for commercial services. Mobile positioning in cellular networks will provide several services such
as, locating stolen mobiles, emergency calls, different billing tariffs depending on where the call is
originated, and methods to predict the user movement inside a region. The evolution to location–
dependent services and applications in wireless systems continues to require the development of
more accurate and reliable mobile positioning technologies. The major challenge to accurate
location estimation is in creating techniques that yield acceptable performance when the direct path
from the transmitter to the receiver is ... Show more content on Helpwriting.net ...
2.1 ARCHITECTURE OF A GEOLOCATION SYSTEM
An example of geolocation system architecture [KOS00] is shown in Figure. As we said earlier, in
order to fix a call the subscriber we are calling must be located accurately. A geolocation service
provider provides location information and location aware services to subscribers. Upon a request
from a subscriber for location information about an MS, the service provider will contact a location
control center querying it for the coordinates of the MS. This subscriber could be a commercial
subscriber desiring to track a mobile device or a PSAP trying to answer an E–911 call. The location
control center will gather information required to compute the MS's location. This information could
be parameters such as received signal strength, BTS ID, TOA of signals, and so on that we discuss
later. Depending on past information about the MS, a set of BS's could be used to page the MS, and
directly or indirectly obtain the location parameters. These are sometimes called Geolocation base
stations (GBSs). Once this information is collected, the location control center can determine the
location of the mobile with certain accuracy and convey this information to the service provider. The
service provider will then use this information to visually display the MS's location to the
subscriber. Sometimes the subscriber could be the MS itself, in which case the messaging and

73. How Do Cell Phones Affect Dna
Cell phones operate with radio frequencies, the cell phones use a lot from the waves
and the waves help. Cell phones do not emit ionizing radiation, the type that damages DNA. The
celluar technology Does works on a system geographically its seperated zones are called cells.
Majority of the cells have its own base station that both and it receivs and it also emits the radio
waves. When the call is then placed from the cell phone and then the signal is sent from
the cell phones antenna to one of the cell's base station called the antenna. Once the base
station transfers the calls to the switiching center the call is then transferred to
another cell phone. Once one of the RF channel is modulated one of the radio signals are then

75. Mobile Communication Is Multi Hop Ad Hoc Systems
INTRODUCTION: The Latest advances in Wireless Communications have extended conceivable
applications from straightforward voice services in early cell systems to new incorporated
information applications. These days, numerous up to date cellular telephones are likewise
incorporated with functionalities including FM radio, advanced camera, and MP3 player. Hence, the
services upheld by mobile communications have extended from basic voice to sight and sound, for
example, video conferencing and portable gaming. These new services require a higher service
quality and also more prominent information rate. Moreover, with mobile access to the Internet, the
expanding development in information movement will further drive the requirement for higher data
transmission. Current foundations that bolster mostly voice activity are confronting an incredible
test in meeting both the transmission capacity and quality of service requests of future mobile
communication clients. For mobile communication, one concept with successful improvement is
customary single–hop cell frameworks where a mobile station (MS) speaks specifically with a base
station (BS) [1]. Another idea of mobile communication is multi hop ad hoc systems, which are
infrastructure less, self–sorting out and quickly deployable with no site arranging, dissimilar to
traditional cell systems. At the point when associations need to move between heterogeneous
systems for performance and high–accessibility reasons, consistent

77. The Effects Of Radio Frequency Waves On Health
Introduction
With cell phone usage increasing, many individuals have become concerned about the health effects
of radiation from cell phones and cell phone towers. In recent years, various studies have been
conducted to determine whether the radio frequency waves from cell phone towers have a
detrimental effect on health. Current research has yielded inconsistent results regarding the effects
of radio frequency waves, and while the World Health Organization does not view radio frequency
waves as serious risk, more research needs to be done in order to be certain (USDA, 2009). In this
paper I will be addressing the following scenario (Case 4):
A mobile phone base station was installed near a neighborhood in order to provide a better service
coverage in 2008. Over the past 5 years, the local residents complained of headache, memory loss,
dizziness, tremors, depressive symptoms, and sleep disturbance. They are concerned that the station
has caused neuropsychiatric problems and some changes in the performance of neurobehavioral
functions. They are more worried about their children, as a few cases of leukemia and brain tumor
have been found in young children (aged 1–3) since then.
In an effort to address the issue of radio frequency radiation exposure in this community, we will
provide a background on the sources of radio frequency radiation as well as the known and
suspected health effects. We will also proposed two epidemiological studies and discuss risk
management and

I. BACKGROUND: CelluComm and GMCT and the Industry AT&T's Bell Laboratories cellular
telephone networking innovation had enabled several cellular network operators to get licenses from
the FCC to operate in separate license territories right about the same time AT&T was broken up in
early 1980s. These operators were either companies like Cellular Communication Services, Inc.
(CelluComm) or small entrepreneurs who had won license territories through the lottery system.
CelluComm's president and founder Ric Jenkins was known for being an aggressive businessman
who had extended it to a 200 million dollar enterprise ranking in the top 20 of the industry. Key to ...

At the beginning he was told to report to Jenkins, however, once he got to the site he was assigned
to Jeff Hardy. After the company reorganization, he found himself wondering whether he should
report to Knight or Hardy. However, despite the confusion, he never brought up this question to
Hardy, Jenkins or Knight. He perhaps then fell into the trap of a "boss
subordinate relationship" and
went with the structure he felt was assigned without truly understanding its reasoning. ii. He didn't
take enough time to understand HQ's perspective on various issues a. Replacing the chief engineer,
rejecting frequency reuse patterns, or failing to get sign off on agreements for GMCT cell sites
indicate failures in managing upward management relationships. Problem #2: Employee Dynamics
Strengths 1. Peterson was committed to building an empowering environment for employees. i.
Peterson called weekly construction meetings, which invited all to report on the company's weekly
progress and issues. Shortcomings 2. He failed to consider alterations in team dynamics when
making hiring and salary decisions. i. He hired Trevor at a higher salary rate to the resentment of
other employees, causing significant damage to the trust and respect between employee and
manager.
