Decrease Subscriber Unit configuration time with integrated and vertical / horizontal polarized antennas Eliminate guess work in locating the remote antennas with audible tone and real-time signal strength measurements Support for both local and remote management , removing the need for expensive on-site supports (Winncom Technologies , 2005 ) Wimax also aimed at providing Internet and telephone service in the most remote areas of the country , may spur BWA market development . For instance , Electronic Russia wants to implement information technologies in municipal organizations and...

The method is aimed at modeling and documenting risks qualitatively and can use both ratio and ordinal scale risk ranking information to prioritize risks reliably . It uses the concept of utility loss to rank the loss associated with risk . Different stakeholder perspectives are explicitly modeled in the Riskit method . The Riskit method has an operational definition and training support (Kontio Basili , 1998 . Most often the problems are caused by the insiders rather than from intruders to data and information . As...

The emergence of SHRM due to heightened concern for agency productivity and accountability means that better information systems are essential (Klingner 1993 . A shift from position management to work and employees . Due to political and economic factors the mind of the manager has sifted towards work management . It also because the employee wants flexibility in their workplace and should awarded and need appraisals from his managers . ``Personnel specialists have continued to demand flexibility and equitable reward allocation through such alterations...

They are connected by the use of a wireless media in a fashion of peer-to-peer . In an Independent Basis Service Set topology , there is a direct communication between the mobile stations . There is a limitation in the communication between a mobile station to the each and other mobile stations because of the limitations in range . Relay functions are not present in an IBSS topology , so all the mobile stations that are connected should be within the range to be able...

This was not first for many applications original 802 .11 wireless items are not being produced . 802 .11 b This was an expansion of 802 .11 specification . 802 .11 used to support bandwidth up to 11 Mpbs , which is similar to the old Ethernet . It makes user of unregulated frequency like the first 802 .11 . frequencies are used to reduce costs of production . 802 .11b can get interference due to microwaves , phones and appliances for 2 .4 GHZ magnitudes . 802...

Graphical User Interface and Mouse are experimentally used by The Xerox Paulo Alto Research Center in 1973 . The first electronic spreadsheet program was used in 1979 . In 1981 , IBM introduced first personal computer with operating system developed by Microsoft . When did it (Information Technology ) begin to impact society ? The impact of science and technology on society is very high . The impact created by the information technology is even higher . It revolutionized the structure of the management and nature of competition...

In 2005 itself , eBay had conducted 8 billion API-based web services transactions (O 'Reilly Musser , 2006 , p . 4 . This implies that Web 2 .0 harbours a very high potential to aid business growth . Web 2 .0 technologies Web 2 .0 technology comprises a set of tools that enable the user to participate more meaningfully in Internet interactions . Users can not only view the contents of websites but can also add to , modify or provide feedbacks to the contents . The way...

The development of remote sensing instruments which operate in space , paved way for the immediate discovery and realization of the effects of global weather disruption patterns and sequences (Sejnowski 2001 . Thermal remote sensing technology uses satellite devices to scout and observe the surfaces of the Earth . This is done through the use of different wavelengths which broaden and widen from the visible area of the electromagnetic spectrum through the thermal infrared to the microwave region . Satellite sensors are most of...

If the functions of sensing and actuation are added to the list , then the new material /alloy is considered a smart material (b ) How MEMS work : The sensors gather information by measuring mechanical , thermal , biological , chemical , magnetic and optical signals from the environment . The microelectronic ICs act as the decision-making piece of the system , by processing the information given by the sensors . Finally , the actuators help the system respond by moving , pumping , filtering or somehow controlling the surrounding environment to...

Like in star and tree topology , a failure in the hub may lead to failure in the entire network . This topology also requires a lot of cables to connect . b ) Ethernet , Token Ring , FDDI , and wireless These are some of the protocols that are used in networking . A protocol can be described as set of rules which are used to govern data exchange or communication in a network . These rules regulate a number of network characteristics including network device access...

Jackson 2001 , p110 . Architecture The architecture of the wireless LAN technology has several definitive terms such as the Station , the Basic Service Set , the Extended Service Set , and the Distribution System . Stations All of the components that literally connect unto the medium of wireless communications within the network are referred to as the station . These stations are equipped with a card known as the WNICs or the wireless network interface card . The stations are also categorized into two categories : the...

Komu Nordstrom , 1999 . Accessibility is another major feature of WLANs that make them easy to attack . Wireless LANs are very easy to access because they need to announce their existence so that existing and potential clients can connect directly to them . This is possible through a special feature known as beacons . These beacons have no privacy functions . The only security methods that can be implemented at this level are encryption and strong accesses control (Johnson , 2002 . Rogue access points can...

ICT skills has been prolific . One area that has had notable development is multimedia where the development of software that make it possible for instructors to develop multimedia and use them in a classroom setting are said to be a revolution in the right direction . Classes that use multimedia are generally more interesting and interactive than those that use single media and this interaction between an instructor and the learner is cited as being central to efficient transmission of theories...

3G ) wireless networks , which involves advantage technology that supports much greater data speeds than the current wireless networks do .Wireless technologies are in a very fragmented state now , with many types of devices on the market using a variety of connection strategies , often incompatible with one another . They can be grouped into three general categories , based largely on the distance the signal needs to travel : personal area , local area and wide area . In the wireless personal area network arena , a...
