...Wireless Technologies and Networks in a Work Environment Edoardo Castillo BIS 221 February 5, 2015 Bill Fennell Wireless technologies and the use of networks have become a great part of our professional lives. We use networks to communicate and share ideas in a professional environment without having to be face-to-face with one another. Some of the advantages wireless technology has given us are mobility, flexibility, increased productivity, and reduced cost of manpower and material. These are just some of the advantages that wireless technology offers us, but we need to keep in mind that there are risks to this technology (Nascio.org, 2004). Although wireless technology has some significant benefits, it also has some disadvantages. Protecting confidential information within a company continues to be a concern for businesses all around the world. Another concern is the strength of a network and its ability to work at its full potential in broad range areas. Implementing a wireless technology like Wi-Fi will increase the productivity of any company or corporation. Wi-Fi will decrease the cost of materials and wires needed to link all of the workstations to a central network. Placing secure Wi-Fi points in and around offices for employees can significantly improve productivity within a period of work time.

... Wi-Fi in the Corporate Environment Business is much different today than it has ever been. The strategies incorporated in the success of a business can be quite complicated and requires more than just a man or woman with a dream. Success in business is now reliant on the connectivity of their business to their local area, as well as, the global market place. Wireless connectivity (Wi-Fi) in the corporate environment is making this possible and beyond possible as it improves. In this paper we will see some pro’s and con’s of wireless connectivity in the corporate environment. Corporations are looking to go wireless for many different reasons. These range from having less wire to having office resources available in the office and in the field. Many companies realize that field productivity and efficiency is slowed down to limited resources of company information. Corporations find that customers sometimes have to wait for price quotes and in turn lose some of those to the competition, since they did not get their information fast enough or the customer was forgotten about. Unfortunately, these things happen in the corporate environment and with the new 802.11g and 802.11n technology, connectivity to company resources is reaching higher levels than ever, so much so, that Wi-Fi is becoming a must in most business environments. More people are using their phones, PDA’s, iPads, and laptops while traveling or away from their desk to get their work done. There are some pros...

...I. Definition of the subject Telecommunications technology is defined as physical devices and software that links various pieces of hardware and transfers data from one physical location to another. Computer networks consist of two or more connected computers that carry information across a wired or wireless technology. The basic hardware needed for the network to operate is a router which directs traffic to different computers and a network card which allows the computers to communicate. These networks include computers, internet services and communication tools which include cell phones, video conferencing, and email. The internet includes the World Wide Web, chat, email, and voice over internet protocol (VoIP), unified communications, and virtual private networks (VPN). Definitions of each term are defined below. • World Wide Web is the most popular internet service. • Chat allows individuals to “talk” live holding and interactive conversation. • Email allows messages to be exchanged from person to person within seconds. It is faster and less expensive than any other delivery method such as the postal or overnight delivery services. • Voice over Internet Protocol (VoIP) allows users to send calls using broadband internet. It allows users to avoid long distance and toll charges normally charged by local companies. “VoIP can reduce communication and network management costs by 20 to 30 percent.” (Laudon, 2010, p. 269) • Unified communications encompasses...

...Wireless Technologies and Networks Wireless Technologies and Networks in the work environment Learning about different forms of communication is always fun and also discussing things that will heighten technology is also great to talk about. When the team got together we had numerous discussions going about that ended up almost like a tree discussion where we obviously knew the base of the talk and then we climbed up the trunk and went into tangents like branches. All in all it was a great conversation and I think the team came out with a great understanding and also more knowledge of the topic. Wireless technology and networks in the work environment are a part of most people’s everyday lives. While I was speaking and contributing to the discussion I realized that my team had more knowledge of the subject then I did and maybe it was better for me to listen and not speak as much as I am an active learner when listening so I can comprehend the information being given. While I was speaking I wanted to stress to my team that privacy and using the wireless technology in the workplace has to be front and center of the discussion. Understanding also that utilizing the different forms of networks in the workplace also will help the speed of getting things done. My portion of the discussion was received well and the discussion on privacy and policy of using the network lasted about twenty minutes so knew that I had brought up a valid topic.

...Fault tolerance: Sensor nodes are fragile and they may fail due to depletion of batteries or destruction by an external event. Realizing a fault-tolerant operation is critical, for successful working of the WSN, since faulty components in a network leads to reduced throughput, thereby decreasing efficiency and performance of the network. STANDARDS OF WIRELESS TECHNOLOGY Because there are multiple technology standards for wireless networking, it pays to do your homework before buying any equipment. The most common wireless technology standards include the following: 802.11b: The first widely used wireless networking technology, known as 802.11b (more commonly called wireless fidelity (Wi-Fi), first debuted almost a decade ago, but is still in use. 802.11g: In 2003, a follow-on version called 802.11g appeared offering greater performance (that is, speed and range) and remains today's most common wireless networking technology. 802.11n: Another improved standard called 802.11n is currently under development and is scheduled to be complete in 2009. But even though the 802.11n standard has yet to be finalized, you can still buy products based on the draft 802.11n standard, which you will be able to upgrade later to the final...

Current 802.11b products operate at 2.4GHz, and deliver up to 11Mbps of bandwidth – comparable to a standard Ethernet wired LAN in performance. An upcoming version called 802.11a moves to a higher frequency range, and promises significantly faster speeds. It is expected to have security concerns similar to 802.11b. This low cost, combined with strong performance and ease of deployment, mean that many departments and individuals already use 802.11b, at home or at work – even if IT staff and security management administrators do not yet recognize wireless LANs as an approved technology. This paper addresses the security concerns raised by both current and upcoming 802.11 network technologies. Wireless LAN Business Drivers Without doubt, wireless LANs have a high gee-whiz factor. They provide always-on network connectivity, but don’t require a network cable. Office workers can roam from meeting to meeting throughout a building, constantly connected to the same network resources enjoyed by wired, ...

...The Advantage of Wireless Systems Learning Team C University of Phoenix BIS/220 Mark Kolesinsky August 1, 2013 The Advantages of Wireless Systems As Party Plates continues to expand, technology must remain a major focus of our growth. While transitioning from Excel to a relational database such as Access will allow our employees to perform their tasks more efficiently and enjoy a greater level of communication, there are other wireless technologies available which can increase both efficiency and communication even further. These wireless technologies and the increased efficiency and production will allow even greater levels of production from our employees and eventually higher profits, in addition to the cost savings which are provided by other features of these technologies. Wireless Local Area Networks The first wireless technology that Party Plates should make use of is a wireless Local Area Network (WLAN). A WLAN would allow Party Plates the benefits of our current Local Area Network (LAN), but also allow several other benefits that we don’t receive from a LAN. With a LAN, an employee must be present at a computer that is connected by cable to the network, along with each printer. With a WLAN, employees could bring their laptops to work and log into the WLAN. Or, since smart technologies are growing rapidly, employees can even access the WLAN on their phones or tablets. This will result in no longer requiring workstations for employees, and instead cause a more free...

...Decide John Doe 9/11/2011 Abstract: This paper is a suggested proposal on how to upgrade a computer network located at Leonard Cooper Charter School. Through interviewing the stakeholders of the organization, I will assess and determine the issues with their current network. Then, I will explain the problems and offer the best solution to their computer networking needs. Computer Network Upgrade Proposal for Leonard Cooper Charter School Current Issues After carefully interviewing the Stake holders of the Leonard Cooper Charter School, several issues were observed. The first noticeable concern was the print server. Their management of print jobs on the print server are called into question because of the many collisions on the print server. They are presently using a half duplex system for their print jobs. A half-duplex system provides signal communication in both directions, however only one direction at a time. A good example of this technology might be two-way radios. The person listening must wait until the transmitter concludes the signal transmission before responding to the call otherwise a collision will occur and the entire message won't get received. In a half duplex Ethernet network, a collision is the result of two devices on the same Ethernet network attempting to transmit data simultaneously. In the event of a network "collision", both transmitted packets are discarded. Collisions are a normal occurrence on Ethernets. To remedy this...

...distribution warehouse approximately ten miles away from the headquarters. Until now, its networks have relied entirely on wired connections. The company’s CIO (chief information officer) decided long ago that she would wait until wireless technology “settled down” before investing in it. 1. What can you tell her about the wireless standards that might convince her that now is the time to adopt wireless technology? There are many advantages to wireless networks. Some advantages of a wireless network are convenience, mobility, ease of set up, the cheaper cost in the long run, and with the newest 802.11 standards the throughput could be just as good as or even better than some Ethernet connections without the hustle of all the wires. 2. Also, what can you tell her to convince her that wireless networking could improve the company’s productivity? With the implication of a wireless network it opens up more options for employees such as the ability to use laptops and their smartphones to complete work so it can be completed however they would like. 3. Which employees could make best use of wireless connections and how? The production, order fulfillment, and research departments would probably benefit the most from the wireless connections so that they can work while on the go and easily update any data even when outside the office. 4.
