When deciding what will benefit society, we evaluate if our actions are ethical or unethical. If the
action is ethical, we would be considered socially responsible. Likewise, if the action is deemed
unethical, then we would be considered socially irresponsible. A company that is focused on good
ethics would be a company with strong social responsibility.
In a business, a code of ethics and ethical behavior guide the employees, management, and
figureheads of the company in its everyday culture. This can be related to the social responsibility
ideology in a variety of ways. Corporate social responsibility, according to the text, is a business's
duty to "pursue policies, make decisions, and take actions that benefit society" (Cengage Learning,
2015). This connects to ethics in that both strive to do what is "right". It is sometimes difficult to
determine what is "right" for the company, however, the overall advancement of society can in
return affect the long term survival and general environment of a company, including Verizon.
2. Which model of social responsibility does Verizon follow? Explain your response.
It seems most logical to concur that Verizon follows the stakeholder's model of social responsibility.
According to the stakeholder model of social responsibility, a stakeholder is one who has an
authentic interest in the company. A stakeholder

Wireless Technology Essay
Wireless technology has become the wave of the future. From cellular phones to wireless point of
sale devices, wireless networks and technology is all around us. In order to jump on the wireless
train, one must first understand the different standards. To properly and safely utilize wireless
technology the user also must understand the various types of wireless security. Once grasping these
technologies and standards, anyone can implement a wireless network in their home. First, the
802.11b wireless networking standard, which is the most common consumer based standard. The
802.11b standard's frequency is in the 2.4 GHz range which is common with most cordless land line
telephones and some microwave ovens. There are not really many ... Show more content on

An upgrade to 802.11b is 802.11g which offers some of the same technology as 802.11b but with
significant upgrades and improvements. The most significant improvement over the 802.11b
standard is the speed. 802.11g supports speeds upwards of 55mbps which is a huge increase over the
11mbps of 802.11b. This standard operates at 2.4 GHz which is the same frequency that the 802.11b
standard operates at. Another great thing about the 802.11g technology is it is backwards compatible
with a 802.11b wireless card so there is no need to go out and buy a new wireless network card for
your computers. Finally a brand new standard that is still in its infancy stages and still has yet to be
ratified by the IEEE is 802.11n. 802.11n will be a huge step towards equality amongst wireless and
wired networks. First, the standard sets a speed requirement of at least 100mbps which is common
amongst most wired computer networks. It is most likely that the throughput will be in the 200mbps
range with a maximum being set in the 600mbps range. Looks like the 802.11n standard will be
operating at both 2.4 GHz and 5 GHz frequencies. Look for the final 802.11n draft out in April of
2009. After choosing a particular standard to go with and buying the equipment to support that
standard, one need to know the method of security they wish to implement on their

Wireless LANs are commonly used on college campuses and most laptops come equipped with
wireless LAN capabilities. They do not have any defined boundaries, which makes it hard for the
user to control the network traffic. Wireless LANs make it possible for people to use the internet
anywhere there is free and non–secured Wi–Fi. The ability to connect wirelessly is based on the
location of the access point. If a person is close to an access point, they can get a strong signal. If
they far, they can get a weak signal or no signal. Wireless LANs can be unreliable as well because of
weather, and the environment. There are many ways to implement Wireless LANs. They are
infrastructure BSS, independent BSS, ESS, and distribution system. The most common way is the
BSS. Wireless LANs have base stations that are connected to a wired infrastructure called access
points. The stations have to communication through the access point. They cannot communicate
directly. Independent BSS is more popular in military applications. Computenetworking.about.com
says, "The key hardware components of a wireless computer network include adapters, routers and
access points, antennas and repeaters."
Wireless LANs have to have wireless network adapters for every device that wants to connect to the

Additionally, the IEEE 802.15.4 protocol may also provide timeliness guarantees by using the
Guaranteed–Time Slot (GTS) mechanism, which is quite attractive for time–sensitive WSNs. In
fact, when operating in beacon–enabled mode, i.e. beacon frames are transmitted periodically by a
central node called the PAN Coordinator for synchronizing the network, the IEEE 802.15.4 protocol
allows the allocation/deallocation of GTSs in a superframe for applications with real–time
constraints. Hence, the GTS mechanism provides a minimum service guarantee for the
corresponding nodes, thus enabling the prediction of the worst–case performance for each node's
application. In this paper, we describe the most important features of the IEEE 802.15.4 protocol
that are relevant for WSNs and we discuss the ability of this protocol to fulfill the different
requirements of WSNs and to resolve inherent paradoxes involving power–efficiency and timeliness
guarantees.

Because of the great diversity of device capabilities, as well as their inherent security limitations,
MSD cannot provide security for data stored locally across every device. Instead, MSD provides
security for corporate data inside the firewall, by securing it against unauthorized access by wireless
devices.
In particular, MSD provides administrators with the ability to (Cohen, 1991):
· Associate a specific, authorized user with each mobile device ("Trusted Devices").
· Specify what wireless networks can communicate with MSD ("Trusted IP Addresses").
Trusted Devices
MSD 's Trusted Devices feature enables administrators both to know what employee is authorized to
use each device, and to control the ability of each user or device to access Domino via MSD. For
example, if an employee loses his or her mobile device, an administrator can immediately disable
the use of that device with MSD, thus eliminating the risk that an impostor will access the network.
In addition to Trusted Devices, MSD offers a related security feature called Dynamic Device/User
Mapping. It works like this: the first time a user successfully enters a valid Domino HTTP username
and password from a properly registered mobile

This trend almost guarantees that demand for wireless products and services will continue to grow
for many years across many sectors. Today, managers and business leaders may be apprehensive to
adopt new wireless technologies over their current wire–bound infrastructures because of quality
and security concerns. This new generation of workers has already entered the workplace and as
they come into positions of more power and influence they are more likely to deploy wireless
solutions, which they have already adopted and become comfortable with. Another growth factor of
the wireless industry is the decrease in market prices and the price elasticity of demand for wireless
products and services.
Advances in technology and increased competition explain the decrease in market prices in the
wireless industry over the past few years. Growth projections of the industry have created an
incentive for more telecommunications carriers to enter the market, resulting in increased
competition. This increased competition has made demand for wireless products and services
elastic, meaning that the percentage change in quantity would be greater than any percentage change
in price (Colander, 2004). This will cause wireless product and service providers to keep prices low
and offer other non–monetary incentives to attract potential customers. But

either inside the experiment or very near to it. A sensor network is a network consisting of
distributed wireless automatic devices using sensors to coordinately monitor physical or surrounding
conditions, such as temperature, sound, stress/ pressure, movements or pollutants etc at different
locations and time. The development of wireless sensor networks was originally motivated by
military applications such as battlefield surveillance. The wireless sensor networks nowadays can be
used in many more application areas, including environment and domain monitoring, medical
applications, intelligent home systems, and traffic commanding.
Sensor nodes will collect environment information and send it towards a sink node, which

The Bell Atlantic [pic] – GTE Merger [pic] The mergers that formed Verizon were among the largest
in U.S. business history, culminating in a definitive merger agreement, dated July 27, 1998, between
Bell Atlantic, based in New York City, and GTE, which was in the process of moving its
headquarters from Stamford, Conn., to Irving, Texas. GTE and Bell Atlantic had each evolved and
grown through years of mergers, acquisitions and divestitures. Each had proven track records in
successfully integrating business operations. Prior to the merger, GTE was one of the world's largest
telecommunications companies, with 1999 revenues of more than $25 billion. GTE's National and
International Operations served approximately 35 million access lines through subsidiaries in the
United States, Canada and the Dominican Republic, and through affiliates in Canada, Puerto Rico
and Venezuela. (Access lines are the individual landline connections from a customer's premises to
the phone network.) GTE was a leading wireless operator in the United States, with more than 7.1
million wireless customers and the opportunity to serve 72.5 million potential wireless customers.
Bell Atlantic was even larger than GTE, with 1999 revenues of more than $33 billion. Its Domestic
Telecom unit served 43 million access lines, including 22 million households and more than 2

INTRODUCTION AND OVERVIEW OF WIRELESS COMMUNICATIONS.

Physical Impact Of Wireless Technology
Wireless technology is very beneficial to human existence, although there is evidence of potential
harm to human health. Devices such as cell phones, computers and televisions, have greatly
improved and have influenced society. With these advantages, health concerns have arisen and been
explored through experiments and surveys. However, these health concerns have not been proven
fully, to an extent they are still impacting humans. By examining the general concern and the social,
mental and physical impacts of wireless technology, it is evident these devices negatively affect
human health.
There are many concerns about the use of technology. The first concern is the gradual increase in
people that use wireless technology. Out of the population of seven billion, roughly six billion
people own a cell phone (Asapscience, 2016). This number has grown greatly since the invention of
wireless technology. The advancement in technology has attracted more people because of
connectability and accessibility. This has resulted in constant usage leading to more time spent on
these devices. Society is altering daily lives by directing most tasks towards technology. By doing
this, it increases time on technology (see Appendix 1). Over the last few years the time spent on
technology has risen greatly. The final concern is the exposure to radiofrequency. Radiofrequency is
a possibly carcinogenic radio wave that comes in two forms; ionizing and non–ionizing radiation.

Wireless technologies in the Oilfield
Introduction
In this research paper I will be exploring the new digital oilfield. This is defined by Sidney Hill of
plantengineering.com as "an oilfield that harnesses information technology in ways that allow an oil
company to capture and analyze data about all of its operations, ideally in real time, thus
maximizing production while minimizing costs."[1] I will cover why this technology has been
brought in, what benefits it brings with it, how they are using it, and the possible threats that are
holding it back.
According to the International Energy Agency, the United States is looking to become the world's
top producer of oil by 2017, a net exporter of the fuel by 2030 and possibly self–sufficient by 2035.
[2] This shows how big the oil industry has become and how much more it could grow. Over the
past several years the United States has seen in explosion of exploration and new drilling operations
being started in remote and geographically challenging areas where communication options are
limited. Due to this, many oil companies are looking into the advantages of using wireless
technologies to improve their profitability, both in these new projects and in their existing
operations. With the understanding that 75% of oil companies having wireless networks in place,
Vodafone Global Enterprises, a worldwide telecommunications company, teamed up with equipment
maker Huawei to conduct a survey with over 100 oil and gas leaders to gauge

Benefits Of A Wireless Technology
Choosing a wireless technology to transmit very small amounts of data from A to B should be very
simple in todays world, but in reality making sense of the wireless connectivity technology
landscape for the Internet of Things is the opposite of simple and obvious – it is a complex
landscape and its getting more complex as time goes by.
In the short range corner we have some familiar LAN and PAN technologies such as Bluetooth, Ble,
Wi–Fi and even Zigbee. Local area network technology will find IoT applications in the home and
office where range is not a priority, if someone finds a way to remove complexity from the process
of setting the IoT devices or else we will find ourself having to adapt long range connectivity
solutions to the ... Show more content on Helpwriting.net ...
So far we have enjoyed LTE–M, LTE–MTC, Cat 1, Cat 0, Cat M, Release–12, Release–13, CIoT,
Extended Coverage IoT and NB–IoT and the milestone date in our diary has slipped March 2016. So
what can we expect then?
NB–IoT could be the long term goal, but we don 't know for sure. What we have until that arrives is
Cat 1. In between, Cat 0 will be skipped outright, and we will also have Cat M as a stepping stone.
The difference between Cat M / NB–IoT and Cat 1 is in the power consumption and cost.
Nevertheless Cat 1 is not where it needs to be. It is the interim solution until we get to Cat M / NB–
IoT. When will these actually arrive? Cat–M is scheduled to be commercially available in 2017,
while NB–IoT is announced for 2018.
Ultimately it won't be a single race of course, and there won't be a single winner. NB–IoT or
whatever it is called when it finally arrives will undoubtedly play a very significant part of the IoT
landscape but not yet and then only for use cases where there is a good fit.Applications where the
value of the individual data streams are relatively high and where energy consumption is not so
critical are a natural fit. The reality of required backward compatibility with a complex legacy (LTE)
technology is that no amount of optimisation will be competitive with a true 'clean–slate'.
The simplistic view from a decade ago is not even close to reality today and the dozen or so

Wireless Communication In Football
With the speed at which sports are played today, the job of an umpire or referee is certainly tricky
and referees are required to make split second decisions that will determine a game, wireless
technology has allowed referees to get a little support. "The use of electronic devices, no matter how
intelligent and accurate, is often criticized by sports fans, and one of the enormous advantages of
wireless communication is the speed of it" (Mark, 2). A referee standing in the middle of a football
field can make a clear audio line with his fellow referees with touch of a button. The technology
allows referees to be able to communicate on and discuss plays without having to take a step further
towards each other. Wireless technology is convenient because of its comfort and ease of use along
with its lack of long wires. The new wireless communication technology has helped speed football
games up along with making calls quicker and more efficiently. For those people on the grown–up
side of 30 years old, football in 2003 doesn't even seem like that was 10 years ago because of the
evolution of the passing game. The NFL has undergone quiet a transformation through the two
quarter backs of Peyton Manning and Tom Brady. In 2003 the NFL officials changed the way that
they enforce pass interference after the New England Patriots used an unstoppable physical defense
to shut down the Indianapolis Colts. As a result of this change, it immediately boosted the passing
game for offenses and

A Survey On Wireless Networks
This chapter is a survey about the wireless technologies that allows us to have self–configured and
self–organized networks. This chapter highlights the design factors, architectures, characteristics and
the advantages of the self configured networks. Also a comparison between WMN and MANET is
presented in this chapter. Application domain of WMN is discussed in the end of the chapter.
2.1 Wireless Networks
One of the most promising and discussed technologies in the past decade is the wireless
communication technology which allows each users to utilize devices that enable the access to
information at any place any time. These demands make wireless communication networks the best
solution for inter connect the devices and people worldwide. Unlike wired communication networks,
which are comprised of devices that can communicate through wires, wireless networks are
comprised of devices that communicate through media such as infra–red and radio signals. Wireless
networks are generally classified into two categories: infrastructure–based and infrastructure less
network (ad hoc wireless networks).
Infrastructure–based wireless network consists of base stations system located in expedient places,
which provide wireless connectivity coverage to devices within their region. Such devices which
provide wireless connectivity are called as access points (AP). Examples of this type are cellular
networks and Wireless Local Area Networks (WLANs). A WLAN is a reliable data communication

Introduction
As wireless technology has begun to mature, the demand for wireless products has increased as new
applications for the technology are realized. One application for wireless technology at the U.S.
Naval Academy is to use the wireless capability to enhance classroom instruction. Currently the
Electrical Engineering and Physics Departments have wireless access points and wireless
laptops/desktops available for classroom instruction. The purpose of this report is to provide the
technical research necessary to aid decision makers in determining which wireless technologies the
Naval Academy should invest.
Background
In a wireless network, computers communicate with the network through a radio ... Show more
Each access point can practically service between 32 to 64 users, depending upon manufacturer. The
bandwidth will be shared by all users. The number of radio channels associated with each
technology will vary by technology and product manufacturer. Multiple channels allows for multiple
access points to be collocated in order to provide access for a larger number of users.
Current USNA Uses
The Electrical Engineering Department currently uses the Dell suite with a wireless access point and
24 wireless laptops. They use the wireless network for "in class" projects where the use of either
simulation (OPNET) or design software (PSPICE) is being taught and used.
The Physics department is using a LinkSys 802.11b wireless access point and LinkSys wireless NIC
cards with desktop computers. Their primary use is for internet access.
Recommendation
The best technology system for the Naval Academy would be the 802.11a standard. It has 54 Mbps
throughput capability as well as adequate range, sufficient for classroom use. Since the 54 Mbps is

shared amongst all users, it would allow, at a minimum, 2 Mbps for each user in a class of 20
midshipmen operating simultaneously. It also has higher data rates at comparable distances

This collaborative effort outlines a comprehensive framework to apply novel radio and optical
wireless communications with channel coding to develop energy–efficient and secure links for the
problem of limited spectrum resource in future wireless applications. In particular, the project aims
to study the fundamental properties and develop practical solutions for a hybrid RF/optical system
that combines energy–efficient ultra–wideband architectures with secure and RF–spectrum–saving
optical technology.

The key idea is to combine the advantages of localized short–range
UWB–IR and longer range optical wireless communication, and use jointly optimized LDPC coding
to improve the link reliability with low complexity encoder and decoder circuits. To achieve these
goals, as illustrated in Fig. 1, the proposed research will also focus on designing the UWB/optical
relaying circuits and hybrid communication protocol, exploiting network diversity and coding for
hybrid channels, and investigating low–complexity LDPC encoder/decoder circuits with soft
information for UWB–IR.
The advantages of UWB–IR and optical communication compensate each other's shortcomings very
well, as illustrated in Fig 1. For example, UWB–IR is power efficient; however, to achieve ultra low
power, the transmission distance of UWB must be short (sometimes less than 1 meter). When a
longer range is demanded, the power consumption of the UWB transceiver increases dramatically
since the received power varies as d−γ, where d is the transmission distance and γ is the path loss
exponent [36–38]. In other words, increasing RF transmission distance will significantly shorten the
battery lifetime. This power/distance trade–off of UWB can be alleviated by employing a
UWB/optical relaying device. The stationary relaying devices use dedicated power lines so the
battery–powered UWB terminals can save

Wireless Networks: Past, Present, and Future
Wireless, or cellular, networks have become one of the most common ways consumer's access data
in today's world. This is quite interesting since the idea of having the ability to access the internet in
any form, let alone having a consistent always on internet connection in the palm of your hand
would have been something out of science fiction or James Bond not that long ago.
Looking at the history of wireless networks can show just how relatively new the technology is. The
first two generations, 1G and 2G, created in the 1980s and used up to the late 1990's, were primarily
designed for voice communications with no real thought given to data. The introduction of 2.5G in
the late 1990s allowed for data activities such as sending and receiving email and web browsing. It
is the third and the current fourth generation, 3G and 4G, that consumers are most familiar with that
ushered in today's mobile data usage.
3G was introduced to the United States in 2003 "with minimum consistent Internet speeds of
144Kbps" (Segan, 2013, para 3) and are capable to get a data connection "anywhere from 400Kbps
to more than ten times that" (Segan, 2013, para 3). This level of connectivity allowed consumers to
connect to the internet at roughly 8 times the speed dial–up modems provided about a decade earlier,
all in the palm of their hand. The first 4G networks began to appear around 2011 offering "networks
that can handle download and upload speeds of up to 75 megabits per second (Mbps)"

Wireless Security Overview
Wireless networks serve as the transport mechanism between devices and among devices and the
traditional wired networks (enterprise networks and the Internet). Wireless networks are many and
diverse but are frequently categorized into three groups based on their coverage range: Wireless
Wide Area Networks (WWAN), Wireless Local Area Network (WLANs), Wireless Personal Area
Network (WPAN )and etc.
WWAN includes wide coverage area technologies such as 2G cellular, Cellular Digital Packet Data
(CDPD), Global System for Mobile Communications (GSM). WLAN, representing wireless local
area networks, includes 802.11, HiperLAN, and several others. WPAN, represents wireless personal
area network technologies such as Bluetooth and IR
All of these represent potential threats in wireless networks as well. However, the more immediate
concerns for wireless communications are:
Denial of service
Malicious hackers
Theft of service (Identity theft / MAC spoofing)
In wireless security, information must be protected from unauthorized, unanticipated, or
unintentional modification. Security requirements include the following:
Authenticity–A third party must be able to verify that the content of a message has not been changed
in transit.
Nonrepudiation–The origin or the receipt of a specific message must be verifiable by a third party.
Accountability–The actions of an entity must be traceable uniquely to that entity.

What is Wireless Power?
Introduction
Imagine travelling away for a vacation without worries when your mobiles or laptops will turn down
as they charge automatically along your trip without connectors or cables. Imagine that you could
grasp your phone on your way morning and charge it whenever you need, at home, work...etc,
wirelessly. It would be better not having charges as we would not have to worry about recycling
power cords. It seems that wireless power is the future. However, Is it feasible or a stuff of science
fiction?
Wireless power is the concept of transferring electrical energy from one point to another without
wires. In the early 20 century, after Maxwells' & Hertz experiments on electromagnetic waves and
before the wire grid, 'Nikola Tesla devoted much effort toward schemes to transport power
wirelessly' (Kurs, 2007). His approach to wireless power use electromagnetic field of some
frequencies using his magnifying coil, he ' transmitted electricity wireless across 15 miles which
illuminated 100 lamps with the charge' (Reddy, 2013). However, according to Reddy, people, who
was walking around, noticed sparks jumping between their feet because of the large undesirable
electric field was produced by the coil. Therefore, the interest of wireless power transmission was
deferred to avoid such results.
In 2007, 'the innovation of wireless electricity started way back at MIT' (Reddy, 2013). In addition,
on that time and because the advance of technology, 'It is also possible to

It's like being trapped in a black hole and you'll get mad repeating it over and over again. Seriously,
a customer wouldn't be impressed by this system. It may be true that WDA gives us a lot of
conveniences than ever but it's like investing on your business' graveyard if you leave your
communication unit unmanaged and unpolished. As Krotz (2008) suggested, technology, indeed,
can never replace human help for customers. Excellent customer service still depends on how
personnel treats and interacts with the customers, not with how efficient the WDA works.
WIRELESS USAGE EXPENSE. Constant calls by the employees not only to unwilling customers
but even to the offices just to check their mails or any agenda also contributes to towering wireless
bills from service providers. The problem with some employees is that they have fooled themselves
that wireless technology is also charge–free. Actually, it is otherwise. Companies spend a lot on
these services and by "lot" it may mean hundreds of thousands to even millions for communication
alone. Aside from these business calls, there are still other calls which are out of the business or
under the table calls which these employees may make. The high cost that the company pays may
not lead to anything useful at all. In the case where an employee's call credit has exceeded the
amount of money his customer/s has brought

Human Area Network (HAN), also referred to as a wireless human area network (WHAN) or a body
sensor network (BSN), is a wireless network of wearable computing devices. In particular, the
wireless network comprises of several miniaturized Body Sensor Units (BSUs) together with a
single Body Central Unit (BCU). The development of WHAN technology started around 1995
around the idea of using wireless personal area network (WPAN) technologies to implement
communications near, on, and around the human body. About seven years later, the term "HAN"
came into existence to refer systems where communication is entirely on, within, and in the
immediate presence of a human body. A WHAN system can use WPAN wireless network
technologies as gateways to reach longer network ranges. Human Area Networking (HAN) is a
technology that safely and securely turns the surface of the human body into a data transmission

Wireless Technology : The Importance Of Wireless Security
In the modern day, wireless technology is buzzing and becoming more and more popular and widely
used as each day passes by. Many big corporations like Apple and Microsoft use wireless storage,
aka the "cloud," to provide their users with convenience. Unfortunately, with the continuous
advancement of wireless technology, securing sensitive information becomes a complicated hassle.
Wireless security is extremely important because many people store sensitive data such as bank
account and credit card numbers wirelessly. Not to mention, many people also perform tasks such as
banking wirelessly. Wireless security is a major risk to everyone who owns wireless devices, not just
big companies. Having strong and effective wireless security is important, so it must be set up
properly in order to protect personal information and prevent hardware damage. Wireless networks
are required to be connected the internet, therefore if it is not secured properly, savvy hackers could
easily intrude. Most people know the obvious first step of securing a wireless network: passwords.
Passwords are key parts to keeping a network's privacy intact. When a new network it setup, it
usually comes with a standard password such as "password" or no password at all. Changing this
password is always the first step to securing a network. Most people like to use passwords they can
remember and often use for everything else, however, people must refrain from doing that. A good,
strong password is consisted of
