1.0 Wireless Fidelity (Wi-Fi) Wi-Fi stands for Wireless Fidelity. Wi-Fi refers to wireless networking technology that allows computers and other devices to communicate over a wireless signal. . It describes all network components that are based on one of the 802.11 standards, including 802.11a, 802.11b, 802.11g, and 802.11n. These standards were developed by the IEEE and adopted by the Wi-Fi Alliance, which trademarked the name "Wi-Fi".
Nowadays, Wi-Fi is used in computer to connect to internet network. Nearly all computers now have a built-in Wi-Fi card that allows users to search for and connect to wireless routers. Many mobile devices, video game systems, and other devices such as I-Phone also include Wi-Fi capability, enabling them to connect to wireless networks as well. These devices may be able to connect to the Internet using a Wi-Fi signal. However, it is important to understand that the Wi-Fi connection only exists between the device and the router. Most routers are connected to a DSL or cable modem, which provides Internet access to all connected devices.
With Wi-Fi nowadays, people easily get to search for the real and newest information on the internet anytime and anywhere where the connection is available.
2.0 Business Drivers for Wireless Technologies
The business industries are going full force with the invention of wireless technologies. Companies worldwide are going wireless to increase productivity, speed delivery to market, and reduce operating costs. Wireless transmissions rely on radio waves, microwaves, and satellites to send data across high frequency radio ranges that later connect to wired media.
The word mobile and wireless is always link to each other, but actually both technologies have different usage. Mobile technology is a collective term used to describe the various types of cellular communication technology while wireless provides users with internet server connection via satellite.
Besides that, the growing use of 3G modem-equipped smart phones and PDAs offers one way to tap into broadband cellular networks by tethering via Bluetooth or USB cable the device to a notebook computer, which can use the phone’s modem to transfer data via wireless. This function, too, has limitations. Initially, some service providers were hostile to tethering efforts and handcuffed devices in efforts to curtail their use. Users also seem to have mixed and inconsistent results with the process, which can require complex configuration and activation steps.
3.0 Advantages of Enterprise Mobility
Enterprise mobility presents opportunities to the business world and challenges to CIOs. Opportunities can be found in new capabilities and applications that will reshape business models empower workers, improve collaboration, help to better manage customer relationships and drive consumer loyalty. CIO challenges include the provisioning, security and ongoing management of these devices.
Furthermore, new mobile applications will enable enterprises to change the way they do business with their employees, partners and consumers. Enterprise mobility can improve an organization’s productivity, optimize logistics operations, manage customer relations and streamline supply chain management. New mobile applications provide sales staff with updated information about their customers and new ways for field forces to work more effectively. By enabling employees to work from anywhere, businesses can also lower individuals’ carbon footprints and improve worker productivity. These applications have made mobility a fact of life for many workers.
Nowadays, there are 3 technologies that influenced business mobility that is Bluetooth, Radio Frequency Identification Tags (RFID), and Satellites.
3.1 Bluetooth
Bluetooth wireless technology is simple, secure and everywhere. It enables wireless connections between huge varieties of devices. Bluetooth technology is built into everything from phones to medical devices; letting you talk, send vital information, listen to music and much more, all without wires. The key features of Bluetooth technology are robustness, low power, and low cost. The Bluetooth Specification defines a uniform structure for a wide range of devices to connect and communicate with each other.
When two Bluetooth enabled devices connect to each other, this is called pairing. The structure and the global acceptance of Bluetooth technology means any Bluetooth enabled device, almost everywhere in the world, can connect to other Bluetooth enabled devices located in proximity to one another.
3.1.1 Range
Range is application specific and although a minimum range is mandated by the Core Specification, there is not a limit and manufacturers can tune their implementation to support the use case they are enabling.
Range may vary depending on class of radio used in an implementation:
* Class 3 radios – have a range of up to 1 meter or 3 feet
* Class 2 radios – most commonly found in mobile devices – have a range of 10 meters or 33 feet
* Class 1 radios – used primarily in industrial use cases – have a range of 100 meters or 300 feet
3.2 RFID
RFID is under Automatic Identification Systems (AISs) which it is superior to bar codes with respect to its technical capability of reading multiple items at a time. The object identification process via RFID is automatic because objects can communicate with each other without human intervention. Active tags have a battery attached that can extend the reading range. RFID tags can withstand harsh conditions. Therefore, management can creatively apply RFID technology in a much wider range of application such as hospital and transportation.
Strategic business values of RFID applications also have business intelligence and security perspectives. The major focus of RFID applications is on the automation of existing barcode-based tracking features. An organization can deliver greater business values by creating a borderless supply chain.
Finally, there are challenges embracing the introduction and development of the RFID system. For example, certain packaging materials and package contents have the effect of erratically reflecting, absorbing or otherwise detuning radio waves. In such cases, what might have been a single application at the beginning of a project becomes more complex and may require a definite technology while permitting specific alternatives with trading partner agreements.
3.3 Satellite
In the context of spaceflight, a satellite is an object which has been placed into orbit by human endeavour. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon.
Satellite Internet access is Internet access provided through satellites. The service can be provided to users world-wide through low Earth orbit (LEO) satellites. Geostationary satellites can offer higher data speeds, but their signals cannot reach some polar regions of the world. Different types of satellite systems have a wide range of different features and technical limitations, which can greatly affect their usefulness and performance in specific applications.
3.3.1 Global Positioning Systems (GPS)
The Global Positioning System (GPS) is a U.S.-owned utility that provides users with positioning, navigation, and timing (PNT) services. This system consists of three segments: the space segment, the control segment, and the user segment. The U.S. Air Force develops, maintains, and operates the space and control segments. GPS satellites provide service to civilian and military users. The civilian service is freely available to all users on a continuous, worldwide basis. The military service is available to U.S. and allied armed forces as well as approved Government agencies.
The outstanding performance of GPS over many years has earned the confidence of millions of civil users worldwide. It has proven its dependability in the past and promises to be of benefit to users, throughout the world, far into the future. For the future of GPS, the United States is committed to an extensive modernization program, including the implementation of a second and a third civil signal on GPS satellites. The second civil signal will improve the accuracy of the civilian service and support some safety-of-life applications. The third signal will further enhance civilian capability and is primarily designed for safety-of-life applications, such as aviation.
3.3.2 Geographic Information System (GIS)
A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts. A GIS helps you answer questions and solve problems by looking at your data in a way that is quickly understood and easily shared.GIS technology can be integrated into any enterprise information system framework.
Geography is the science of our world. Coupled with GIS, geography is helping us to better understand the earth and apply geographic knowledge to a host of human activities. The outcome is the emergence of The Geographic Approach, a new way of thinking and problem solving that integrates geographic information into how we understand and manage our planet. This approach allows us to create geographic knowledge by measuring the earth, organizing this data, and analyzing and modelling various processes and their relationships. The Geographic Approach also allows us to apply this knowledge to the way we design, plan, and change our world.
GIS benefits organizations of all sizes and in almost every industry. There is a growing awareness of the economic and strategic value of GIS. The benefits of GIS generally fall into five basic categories:
· Cost Savings and Increased Efficiency
· Better Decision Making
· Improved Communication
· Better Recordkeeping
· Managing Geographically
