Elliot, R. (2002). Wireless information management. http://proquest.umi.com/pqdweb?RQT=318&pmid=23201&TS=1071005374&clientId=13245&VType=PQD&VName=PQD&VInst=PROD" Information Management Journal, 36(5): 62-66
Wireless technologies are portable systems that use radio signals for the exchange of data. In other words, wireless system is always connected with the data. A number of examples of wireless systems are personal digital assistants (PDAs), robots, telehealth apparatus, pagers, telephones, tablet computers and subnotebook computers (smaller, lighter portable computers), smart telephones, wireless networks.
Wireless applications use a range of communication infrastructure including cellular, wireless local area networks (LANs), and wireless wide area networks (WANs). Cellular and microcellular transmissions use radio waves to send and receive data from wireless platform devices such as cellular phones, PDAs, or specially equipped portable computers.
But cellular transmission is vulnerable to noise and interference. Wireless LANs consist of a traditional LAN with a wireless interface card. The data transmission rate of wireless LANs is considerably higher than that of cellular transmission. Current wireless WAN service providers use satellite transmission to provide the nationwide, two-way communications at the relatively low speeds and high prices.

The authors argue that in recent years the areas of mobile computing and wireless networks have seen an explosive growth both in terms of the number of services provided and the types of technologies that have become available. It is anticipated that in the future, mobile users will be able to access their data and other services such as electronic mail, video telephony, stock market news, map services, electronic banking, while on the move.
3. Advani, R. And Choudhury, K. (2001). Making the most of B2C wireless. Business Strategy Review, 12(1): 39-49.
Although wireless technology is still emerging, yet many organizations are making considerable investments to take advantage of the new business opportunities offered by wireless technologies. Several companies are, however, susceptible to the uncertainty involved in the use of wireless "killer applications" and the timing and capability of next-generation wireless technologies. The authors argue that the best way to approach the opportunities of wireless networks is not to find a single "killer application, but to identify "killer experience" to staify the needs of the customers.
4. Malladi, R. And Agrawal, (2002).
Current and future applications of mobile and wireless networks. Communications of the ACM, 45(10): 144-146.
Using the improved cellular network, hundreds of individuals and companies, large and small, have already begun to adjust to the effects of using wireless data in their businesses. And many organizations are still looking for transparent and standard set of interfaces that support their wireless computing applications, including e-mail, data base access, and online services.
5. Brodsky, I. (1997). The net unplugged. Telephony, 232 (9): 50.
Wireless technology will be increasingly used for stimulating access to time- and location-sensitive information. Wireless access will provide efficient use of the Internet. Wireless users will access the Internet from hand-held portable devices. Wireless will make it practical to use the Internet from virtually anywhere. It is very likely that content targeted at mobile and remote users will grow particularly content intended for access from cellular and PCS handsets and pagers. Therefore the wireless Internet technologies can be expected in the near future.
6. Rob, F. (1995). Universal personal communications in the new telecommunications world order: Access to wireline networks. Telecommunication Policy, 19(1): 43-49.
The author makes the point that while wireless technology offers various opportunities for customer services, it also creates needs for management, planning, operating, service, and regulatory decisions.
Several technologies developed in cellular systems. First, the industry has been able to develop standards that facilitate handoffs between systems and the provision of automatic roaming. Automatic roaming refers to the ability of the customer to place and receive calls automatically as he/she moves across different cellular systems and utilizes infrastructure equipment manufactured by different vendors.
7. Shih, G. And Shim, S. (2002). A service management framework for M-commerce applications. Mobile Networks and Applications, 7(3): 199.
In this paper, the authors provide an overview of mobile commerce. According to the authors, mobile commerce (m-commerce) refers to an ability to conduct wireless commerce transactions using mobile applications in mobile devices. M-commerce applications can vary from as simple as an address book synchronization to as difficult as credit card transactions. The authors argue that M-commerce is expected to grow dramatically in the near future supporting simple to complex commerce transactions. Even though the Wireless Application Protocol (WAP) is designed to facilitate the development of wireless applications, it will not be sufficient to handle complex business transactions that require cooperation of different service applications. In order to handle these complex mobile commerce transactions efficiently, an intelligent, robust and scalable framework that provides diverse m-commerce services is required.
8. Joshi, A. And Krishna, A. (2001). Broadband wireless. Journal of High Speed Networks, 10(1): 1-6.
The authors discuss on the issue of international wireless standards. The authors describe the case of The Bluetooth wireless technology, which is aiming at uniting personal computing devices into a collaborative, interconnected electronic community. In Fobruary 1998, According to the authors, Ericsson, IBM, Intel, Nokia, and Toshiba formed the Blue-tooth Special Interest Group to work the development of an international communications standard for simplifying interactivity between personal devices. As of today, this interest group has grown to nine promoters and over 2100 adopters including all sorts of industrial, scientific, and educational institutions.
9. Zimmerman, T.G. (1999). Wirelss networked digital devices: A new paradigm for computing and communication. IBM Systems Journal, 38(4): 566-575.
This paper first examines the technology used for wireless communication. Putting a radio in a digital device provides physical connectivity; however, to make the device useful in a larger context a networking infrastructure is required. The infrastructure allows devices to share data, applications, and resources such as printers, mass storage, and computation power. Defining a radio standard is a tractable problem as demonstrated by the solutions presented in this paper. Designing a network infrastructure is much more complex. The second half of the paper describes several research projects that try to address components of the networking infrastructure.
10. Sestito, S. 1995. Just-in-time information: wireless technology and the professional. CPA Journal, 65 (11): 38-40.
The author argues that in today's dynamic world, just-in-time flow of information has become increasingly important. That means, providing right data, right place, right time, anywhere, anytime. In today's world, businesses would not take risks of taking too long to respond to change. This phenomenon has given birth to the wireless technology that can provide access to firm's database, an online accounting/tax database, or the Intemet, from anywhere around the globe.
The Impact of Wireless technology within the Next Decade
In future, I believe that wireless systems will have a huge impact on the computing industry. Without being worried about the need of hard-wires, people can quickly find information on different activities instantly through wireless technology. Presently, because of the low band-width, the signals are not clear. Moreover, portable devices consist of small screen that makes it difficult to receive a lot of information. However, I believe in future, there will be a lot of improvement in both of these fronts, so that wireless technology becomes commonplace not only in communication, but also in instant networking and real-time data transmission.

In actual fact, because of STCP's option of multiplicative amplify, STCP have to in stable state persuade congestion actions approximately all 13.4 round trip times, in spite of the connection speed. HSTCP encourages packet losses at a slower speed than STCP, but still much quicker than RCP-Reno. 3. Problems of the Existing Delay-based TCP Versions In contrast, TCP Vegas, Enhanced TCP Vegas and FAST TCP are delay-based protocols. By relying upon
Nanotechnology attempted to show the potential of this new technology and included the wide range of fields that are connected to the concept of the nanometer scale. These include machining, imaging, metrology or measurement, micromachines, instrumentation and machine tools, scanning probe microscopy, fabrication of components, nanoelectronics, molecular engineering, among others. (Journal Review: Nanotechnology) Another important step in the development of this technology in both a practical and theoretical sense was
" The problem with these primitive models is that they are still mainly oriented on data retrieval rather than optimal voice transmission. However, research is well on the way and it seems that it will be less than a year before we can talk about Voice over WiFi or VoWiFi. On the other hand, it is obvious that there are several problems that the VoWiFi providers will have to deal with
875). Often success introduces complacency, rigidity, and over confidence that eventually erode a firm's capability and product relevance. Arie de Geus (1997) identified four main traits for a successful firm; the first is the ability to change with a changing environment (Lovas & Ghoshal, 2000, p.875). A successful firm is capable of creating community vision, purpose, and personality, and it is able to develop and maintain working relationships. Lastly, a
Disaster Recovery Intrusion detection is the method of keeping track of the events taking place inside a computer or perhaps a network and then examining them to get indications of potential situations, that are transgressions or impending dangers of breach of IT security procedures, appropriate usage guidelines, or standardized security strategies. Intrusion prevention is the method of carrying out intrusion detection as well as trying to stop recognized potential situations.
Verizon Communication Telecommunication industry is one of the fastest growing industries in the world, with advancement in internet technology, advancement in trade and commerce, social dynamics and an ever-expanding global market. Telecommunication has become one of the most essential mediums that facilitate communication, interaction and transaction in both social and economic platforms. To this end, many companies have invested billions of dollars worldwide in an attempt to rip some of the
This means that you must continually monitor and communicate about possible changes, pertaining to the overall scope of the threat. Once this occurs, is when an entity will have an effective security procedure that will adapt to the various changes that are taking place. This is significant, because this information can be used to corroborate the overall nature of security threats that could be faced by the SME. Where, this
