CHAPTER 7 NETWORKS, TELECOMMUNICATIONS, AND MOBILE TECHNOLOGY

1. CHAPTER 7 NETWORKS, TELECOMMUNICATIONS, AND MOBILE TECHNOLOGY Networks and telecommunications are the transmission of signals over a distance for the purpose of communication. In modern times, this process almost always involves the sending of electromagnetic waves by electronic transmitters but in earlier years it may have involved the use of smoke signals, drums or semaphore. Today, network and telecommunication is widespread and devices that assist the process such as the television, radio and telephone are common in many parts of the world. There is also a vast array of networks that connect these devices, including computer networks, public telephone networks, radio networks and television networks. Computer communication across the Internet, such as email and instant messaging, is just one of many examples of telecommunication.

4. LEARNING OUTCOMES 7.1 Compare LANs, WANs, and MANs 7.2 Describe the business benefits associated with VoIP 7.3 Explain the difference between a VPN and a VAN 7.1. Compare LANs, WANs, and MANs. A local area network (LAN) is designed to connect group of computers in close proximity to each other such as in an office building, a school, or a home. A wide area network (WAN) spans a large geographic area, such as a state, province or country. WANs often connect multiple smaller networks, such as local area networks (LANs) or metropolitan area networks (MANs). A metropolitan area network (MAN) is a large computer networks usually spanning a city. 7.2 Describe the business benefits associated with VoIP. VoIP uses existing network and Internet infrastructure to route telephone calls more efficiently and inexpensively than traditional telephone service, VoIP offers businesses significant cost savings, productivity gains and service enhancements. 7.3 Explain the difference between a VPN and a VAN. A virtual private network (VPN) is a way to use the public telecommunication infrastructure (e.g., Internet) to provide secure access to an organization�s network. A valued-added network (VAN) is a private network, provided by a third party, for exchanging information through a high-capacity connection. 7.1. Compare LANs, WANs, and MANs.

5. LEARNING OUTCOMES 7.4 Identify the advantages and disadvantages of broadband technology 7.5 List and describe many of the network security problems 7.4 Identify the advantages and disadvantages of broadband technology Digital Subscriber Line (DSL) - Good upload rates, uses existing telephone lines, but speeds vary depending on distance from telephone company's central office and slower downloads than less expensive alternatives. Cable - uses existing cable infrastructure, low-cost equipment, but shared connections can overload system, slowing upload times. TI/T3 Dedicated Line - uses existing phone wiring, but performance drops significantly with range and susceptible to crosstalk. Fiber-to-the-Home (FTTH) - fast data speeds, infrastructure has long life expectancy, low maintenance, low power costs, but not widely available and significant deployment cost (for company). Fixed Wireless - typically inexpensive to install, no underground digging, but weather, topography, buildings, and electronics can cause interference. Satellite - nearly universal coverage, available in otherwise inaccessible area, but expensive service/equipment and upload/download delays. 7.5 List and describe many of the network security problems. An organization has to be concerned about proper identification of users and authorization of network access, the control of access, and the protection of data integrity. Almost all networks require some kind of logon, including user name and password. Many people are casual with their passwords, making them easy to guess. A good password has both letters and numbers along with a few punctuation marks for added security. Most corporate security goes far beyond passwords such as using a "firewall," a computer that sits between an internal network and the Internet. The firewall allows access to internal data from specified incoming sites but tries to detect unauthorized access attempts and prevent them from occurring. 7.4 Identify the advantages and disadvantages of broadband technology Digital Subscriber Line (DSL) - Good upload rates, uses existing telephone lines, but speeds vary depending on distance from telephone company's central office and slower downloads than less expensive alternatives.

9. VOICE OVER IP (VoIP) Voice over IP (VoIP) - uses TCP/IP technology to transmit voice calls over long-distance telephone lines Numerous vendors offer VoIP services; however, the service works differently depending on the vendor�s IT infrastructure The start-up Skype pairs P2P (peer-to-peer) technology with a PC�s sound card to create a voice service, which the user can use to call other Skype users Vonage lets the user place calls to any person who has a mobile or landline (regular telephone) number Vonage sends the call over a cable via a digital-to-analog converter A few providers even offer an adapter for a traditional handset that plugs into a broadband modem All of these vendors are providing VoIP, but the service and its features can vary significantly Unfortunately, VoIP routes calls through the same paths used by network and Internet traffic, therefore it has the same vulnerabilities and is subject to the same Internet threats. Much like data, VoIP traffic can be intercepted, captured or modified. Any threat that slows down or degrades service even slightly will disrupt business. As a result, VoIP traffic must be secured.

11. NETWORKING BUSINESSES Industry-leading companies have developed Internet-based products and services to handle many aspects of customer and supplier interactions Customers now expect seamless retailing between online and in-store Some companies, such as Best Buy, Circuit City, Office Depot, and Sears, already have their physical and online stores integrated. These companies have been the fast movers because they already had an area in their stores for merchandise pickup (usually for big, bulky items such as TVs and appliances), and because long before the web they had systems and processes in place that facilitated the transfer of a sale from one store to another. To take on the challenge of business integration, an organization needs a secure and reliable network for mission-critical systems.

15. INCREASING THE SPEED OF BUSINESS Bandwidth - is the difference between the highest and the lowest frequencies that can be transmitted on a single medi�um, and it is a measure of the medium's capacity Broadband - refers to high-speed Internet connections transmitting data at speeds greater than 200 kilobytes per second (Kbps) To transmit one page of text over a 128,000 bps (128 kbps) DSL line would take only four-tenths of a second. Graphics require approximately one million bits for one page. This would require about 8 seconds over a 128 kbps DSL line. Full-motion video transmission requires the enor�mous bandwidth of 12 million bps, and thus data compres�sion techniques must be employed to be able to send video over the existing telephone network. The bandwidth deter�mines what types of communication � voice, data, graph�ics, full-motion video � can reasonably be transmitted over a particular medium.

19. SECURING BUSINESS NETWORKS There have been many network security problems - networks are a tempting target for mischief and fraud An organization has to be concerned about� Proper identification of users and authorization of network access The control of access, and the protection of data integrity An organization has to be concerned about proper identification of users and authorization of network access, the control of access, and the protection of data integrity. Almost all networks require some kind of logon, including user name and password. Many people are casual with their passwords, making them easy to guess.

20. Data Sharing Even more important than the sharing of technology resources is the sharing of data Either a LAN or a WAN permits users on the network to get data (if they are authorized to do so) from other points on the network It is very important, for example, for managers to be able to retrieve overall corporate sales forecasts from corporate databases to use in developing spreadsheets (or any other program used for business analysis) to project future activity. In order to satisfy customers, automobile dealers need to be able to locate particular vehicle models and colors with specific equipment installed. Managers at various points in a supply chain need to have accurate, up-to-date data on inventory levels and locations. Accountants at corporate headquarters need to be able to retrieve summary data on sales and expenses from each of the company's divisional computer centers. The chief executive officer, using an executive information system, needs to be able to access up-to-the-minute data on business trends from the corporate network.

Manufacturers improve supply-chain planning and execution by incorporating RFID technologies. By placing RFID tags on cases and pallets shipped from manufacturers to distribution centers, companies would be able to keep close tabs on their shipments. In turn, that would allow distribution centers and its suppliers to streamline their supply chains and ultimately ensure shelves were always fully stocked. 7.11 List and discuss the wireless trends that consumers and businesses can benefit from. Social Networking Gets Mobilized. Mobility is added to existing Internet business models, services and behaviors, driving traffic for wireless operators. Social networking applications initially are preloaded on many mobile devices sold and later become downloadable. Mobile TV. Per-view or per-minute pricing for �sneaking,� a consumer tendency to watch key minutes of a sports event or drama while engaged in another activity. Sneaking leads to more regular viewing, and within 3-5 years, mobile TV will become an indispensable service. Multi-Function Devices Become Cheaper and More Versatile. Intense competition and margin pressure will continue in the handset market, forcing prices of third-generation (3G) handsets below $90 and making them affordable for a wide range of users. Location-Based Services: GPS is the location technology of choice for the wireless industry. Handset manufacturers will continue to push GPS-enabled handsets as the technology evolves from popular in-car satellite navigation systems to a broadly accepted feature in wireless phones. Mobile Advertising. Major brands are shifting from basic SMS marketing to more sophisticated multimedia advertising. Wireless Providers Move into Home Entertainment. Mobile makes headway against fixed broadband operators, who have dominated Internet and cheaper voice service provision in the home. Wi-Fi will remains the primary wireless access technology.

31. USING CELLULAR TECHNOLOGIES IN BUSINESS Cellular telephones (cell phones) work by using radio waves to communicate with radio antennas (or towers) placed within adjacent geographic areas called cells A telephone message is transmitted to the local cell by the cellular telephone and then is passed from antenna to antenna, or cell to cell In less than twenty years, the mobile telephone has gone from being rare, expensive equipment of the business elite to a pervasive, low-cost personal item. Several countries, including the UK, now have more mobile phones than people. There are over five hundred million active mobile phone accounts in China. Luxembourg has the highest mobile phone penetration rate in the world, at 164%. The total number of mobile phone subscribers in the world was estimated at 3.3 billion at the end of 2007, thus reaching an equivalent of over half the planet's population. At present, Africa has the largest growth rate of cellular subscribers in the world, its markets expanding nearly twice as fast as Asian markets. The availability of prepaid or 'pay-as-you-go' services, where the subscriber is not committed to a long-term contract, has helped fuel this growth in Africa as well as in other continents.

35. Personal Data Assistants Personal digital assistants (PDA) are small, handheld computers capable of entirely digital communications transmission Smartphone - combines the functions of a cellular phone and a PDA in a single device The first generation of successful PDAs were Palm Pilots. They primarily functioned as electronic organizers with support for address books, calendars, email, notes, etc. The PDA only occasionally needs to connect to a companion PC for "synchronization." For instance, a PDA can be synchronized with a PC address book, calendar, and email inbox, via a USB cable. Newer PDA models can also connect to PCs wirelessly via Bluetooth (which we describe in the next section), or connect to the Internet via wireless.

54. MOBILE WORKFORCE TRENDS Social networking gets mobilized Mobile TV Multi-function devices become cheaper and more versatile Location-based services Mobile advertising Wireless providers move into home entertainment Wireless security moves to the forefront Enterprise mobility Social Networking Gets Mobilized. Mobility is added to existing Internet business models, services and behaviors, driving traffic for wireless operators. Teens and twenties accustomed to constant connectivity and habit-forming websites, such as MySpace and Facebook, lead a wave of membership in mobile social networks. Location social networking including friend and event finder services are gaining popularity, even in the professional and over-50 segments. Google, Yahoo!, and Skype are more compelling for users than wireless brands, which are hard-pressed to compete. Social networking applications initially are preloaded on many mobile devices sold and later become downloadable. Mobile TV � Now Showing for Early Adopters. In the short term, wireless users are unlikely to plunk down $5.99-9.99 per month for mobile TV service. Instead, look for per-view or per-minute pricing for �sneaking,� a consumer tendency to watch key minutes of a sports event or drama while engaged in another activity. Sneaking leads to more regular viewing, and within 3-5 years, mobile TV will become an indispensable service. Broadcast TV is the primary driver of revenues and consumer adoption, but peer-to-peer video is gaining interest, too. Operators are squaring off with content providers over control of the subscriber relationship and user experience. Multi-Function Devices Become Cheaper and More Versatile. Intense competition and margin pressure will continue in the handset market, forcing prices of third-generation (3G) handsets below $90 and making them affordable for a wide range of users. Seeking to replicate the success of camera phones, device manufacturers will produce more multi-function units with music-playing, location, video and other capabilities. Twenty percent of all handsets sold in North America are application specific � built for a usage proposition, such as music or video consumption or business productivity. Location-Based Services: And the Winner Is ... GPS! Yes, GPS is the location technology of choice for the wireless industry. Handset manufacturers will continue to push GPS-enabled handsets as the technology evolves from popular in-car satellite navigation systems like TomTom to a broadly accepted feature in wireless phones. With Nokia having launched its first GPS-enabled handsets in early 2007 and bandwidth available to support new multimedia services, location-based service providers are building critical mass. Since there are 10 to 20 times more mobile phones sold than any other consumer electronics device, wireless is a huge driver for GPS adoption. Mobile Advertising Breaks Loose. Major brands are shifting from basic SMS marketing to more sophisticated multimedia advertising. RBC Capital Markets expects mobile marketing revenues to balloon from $45 million in 2005 to $1.5 billion by 2010. With the technological ability to target and measure the effectiveness of mobile advertising, brands are more strategic in their approach. Rich 3G content and video services and accuracy advancements in GPS-based location services deliver further value to brands targeting existing and potential customers in innovative ways. Wireless Providers Move into Home Entertainment. Mobile makes headway against fixed broadband operators, who have dominated Internet and cheaper voice service provision in the home. Wi-Fi will remains the primary wireless access technology. The fixed operators may be strengthened by Wi-Fi capabilities in consumer electronics devices (set-top boxes, game consoles and MP3 players) that enable cost-effective content downloads. Wireless Security Moves to the Forefront. There is a monumental need to put strong security measures in place. This could be the year that hackers really start paying attention to millions of wireless devices, the growth in mobile data usage and vulnerable points between mobile and fixed networks. CIOs consistently cite security as their number one concern in extending network access to wireless devices. Attacks, viruses and data security now exceed device loss or theft as concerns. Emerging services, such as VoIP and mobile payments, provide additional challenges. Vulnerabilities directly affect the bottom line, corporate image, regulatory compliance and competitive advantage. Enterprise Mobility � It�s for Real Now. Enterprises can�t resist the convenient, reliable, attractively priced, bundled mobile solutions entering the market. Corporations switch from phones to mobile computers for transactions, data collection and messaging for a wide variety of employees. Many voice communications processes, such as order placement and delivery notifications, dispatch operations and remote asset monitoring, continue to shift to wireless data to increase information access and field transaction volume across organizations. Many corporations will completely replace their cellular handsets with a combined voice/data device or a data-only device.Social Networking Gets Mobilized.

Describe the differences between UPS and FedEx�s use of wi-fi FedEx deploys new technologies as soon as it can justify the cost and demonstrate improved efficiencies and customer benefit. UPS refreshes its technology base roughly every five to seven years, when it rolls out a unified system in stages that it synchronizes with the life span of the older system. The two companies are exploiting new wireless technologies in their differing attempts at aiding the two main components of their operations: pickup/deliver and packaging/sorting. 3. Identify two types of wireless business opportunities the companies could use to gain a competitive advantage The companies can use Bluetooth, RFID, satellite, and GPS to gain competitive advantages. GPS can help with ensuring drivers are using the most direct route, or avoiding traffic, to reach customers. Satellites could be used to gain access to company intranets from anywhere at anytime. 1. Explain the fundamentals of wireless fidelity Wireless fidelity (wi-fi) is a means of linking computers using infrared or radio signals. Wi-fi is a type of Ethernet, which makes the wireless network a straightforward extension of the wired network.

61. CLOSING CASE THREEImproving IT�s Bedside Manner at Florida Hospital Explain how hospitals are using telecommunication and network technologies to improve their operations Identify a new telecommunication or network product that Florida Hospital could use to improve its operations Why is real-time information important to hospitals? 1. Explain how hospitals are using telecommunication and network technologies to improve their operations. Hospitals are using everything from digital doctors to prescription fulfillment. There are so many new and exciting uses of technology to make hospitals more efficient and effective which saves lives. The most important piece of Hackensack�s digital initiatives is the networked software that acts as the hospital�s central nervous system. Using wireless laptops, nurses log in to the system to record patient information and progress. Doctors tap into the network via wireless devices to order prescriptions and lab tests. Everything is linked, from the automated pharmacy to the X-ray lab, eliminating the need for faxes, phone calls, and other administrative hassles. 2. Identify a new telecommunication or network product that Florida Hospital could use to improve its operations. Student answers to this question will vary. This is a good opportunity for students to get creative and develop some interesting products such as PDA devices to send notes and prescriptions. 3. Why is real-time information important to hospitals? Real-time information is critical for hospitals to respond to patient needs and care. Real-time information gived health-care professionals access to the most accurate and current medical information at a patient's bedside via their personal digital assistants (PDAs) or other portable devices. Using real-time information is designed to help health care professionals provide better patient care by increasing their ability to securely access patient records, lab results and pharmacy data, and view diagnostic images such as X-rays or CT scans from anywhere in the hospital. 1.

62. CLOSING CASE THREEImproving IT�s Bedside Manner at Florida Hospital How is Florida Hospital using wireless technology to improve its operations? Identify several wireless technologies that are changing the way businesses operate and explain how hospitals can use these technologies to improve their operations 4. How is Florida Hospital using wireless technology to improve its operations? The wireless technology increases efficiencies and productivity with better, real-time access to information. The technology is designed to help health care professionals provide better patient care by increasing their ability to securely access patient records, lab results and pharmacy data, and view diagnostic images such as X-rays or CT scans from anywhere in the hospital. 5. Identify several wireless technologies that are changing the way businesses operate and explain how hospitals can use these technologies to improve their operations. The possibilities for wireless technology are endless. As computers are combined with various forms of hospital devices such patient monitoring systems and X-rays, it won�t be long before wireless networks are as ubiquitous as refrigerators and dishwashers. Hospitals will use wireless networks to connect handheld devices with data storage devices and allow patient-care workers to roam untethered through hospitals. In the long run, wireless networks will be cheaper for hospitals since no structural changes will need to be made to the building�s walls, ceilings, or floors. If they want to add equipment, hospitals simply add another node to the network. Hospitals won�t have to cut holes, run wires, or alter the physical structure at all. Hospitals should use RFID to: Continuously track each patient's location Track the location of doctors and nurses in the hospital Track the location of expensive and critical instruments and equipment Restrict access to drugs, pediatrics, and other high-threat areas to authorized staff Monitor and track unauthorized persons who are loitering around high-threat areas Facilitate triage processes by restricting access to authorized staff and "approved" patients during medical emergencies, epidemics, terrorist threats, and other times when demands could threaten the hospital's ability to effectively deliver services Use the patient's RFID tag to access patient information for review and update through a hand-held computer 4.

63. BUSINESS DRIVEN BEST SELLERS THE POWER OF MOBILITY, by Russell McGuire Over eighty percent of Americans above the age of five own a cell phone, most with digital cameras built in, and bundled with an e-mail service specifically designed for sending those captured moments to friends and family. These consumer applications are just simple examples of mobility being built into everyday products to create tremendous new value. From a business perspective, a new technology can introduce radical changes�changes so dramatic that they fundamentally change the nature of the business, the nature of the product, and the reasons why customers buy the product. When this happens, the rules of competition change. It is happening now: the Age of Mobility is upon us. How will it impact you and your business in the months and years to come? The Power of Mobility shows you how to look forward, envision the Power of Mobility in your business, and implement the steps required to turn vision into reality.?Russell McGuire, one of the telecom industry's leading strategists, details the specific actions you must take to deliver the tremendous value that mobility adds�and win customers' hearts and wallets. He presents a powerful framework for capturing the Power of Mobility: the Seven Steps. If you can Digitize, Connect, Evaluate, Limit, Position, Protect, and Learn, you will capture the Power of Mobility in your products, your services, and your processes. He further clarifies the power of the Seven Steps with illustrative case studies of seven companies that have successfully implemented this framework and redefined the rules of competition in their industries. The Mobility Age represents a great opportunity for businesses large and small to capture the Power of Mobility in order to create competitive differentiation and to take market share. Stories of businesses that have been crushed by the competition because they have denied the changes brought by technologies in the past will likely be repeated. You have a choice. You can wait for a competitor to lead and define the rules to his benefit and your demise. Or you can lead and set the rules � if you capture The Power of Mobility now.

64. BUSINESS DRIVEN BEST SELLERS INTO THE UNKNOWN, by Jack Uldrich Latching onto the idea that everything old is new again, Uldrich, a former naval officer and author of The Next Big Thing Is Really Small, puts forth Lewis and Clark as two shining examples of all that is right with leadership and management. Spotlighting the pair's many strong points, from people skills and future-thinking capabilities to optimism and an ability to see the forest as well as the trees, Uldrich (drawing on what has obviously been years of extensive research) points to modern-day companies like Coca-Cola, General Electric and DaimlerChrysler as entities that could all learn something from Lewis and Clark. Whether the "project" is a westward expedition or a hostile corporate takeover, Uldrich makes the case that the past is not so different from the present�or from the future � especially when concerning new technologies. The parallels between these men and today's leaders are intriguing and well thought out. For corporate types looking for tips, there is certainly plenty to digest. The overriding messages are clear: mentor and be mentored; find a way to balance the task at hand with the overall future vision; maintain a confident and optimistic approach from the beginning.
