Introduction and Overview of Wireless Technology:
• 802.11b (or WiFi) is the current standard in today’s wireless networking environment.
• 802.11b is a standard based technology, meaning that one manufacture’s wireless equipment which adheres to the standard will be interoperable with that of another manufacturer. It is important to note that some manufacturers have added additional functionality to their products. As these features or functionalities are not part of the standard, so they may not work with products from other vendors.

For the most part, schools march their children to a computer lab once a week where they are then suppose to learn “how to use the computer.”
Kids aren’t getting the opportunity to use computers and explore their full potential. They are using them as no more than over-priced typewriters.
Use of Wireless Laptops in the classroom, gives students the opportunity to use the computer to take notes, organize projects and research without leaving their seats.

Wireless allows for ubiquitous use of technology in the classroom and building as a whole.
It helps to foster discovery-based learning, making the school day less boring.
Wireless fosters wonderful opportunities for human interaction by offering one on one or small group collaboration.

Wireless allows for learning by doing, instead of learning by being told.
It allows homogeneous schools to bring more diversity into the classroom. It allows us to build bridges of understanding between people of different cultures around the world, and to help us realize how much we have in common and appreciate our differences.

With wireless connectivity, teachers no longer have to worry about having lab time in order to use the computers, the classroom now becomes the lab.






Advantages:

 Ease of Movement
Laptops allow for easy movement within a classroom or anywhere around the campus.
o Due to size and portability, laptops provide enough computers in a classroom to make the use of a computer a helpful teaching utility.
o When a technology lesson is over, the laptops can just be put away. Other lessons can then continue with little interruption.


Ease of movement is likely to encourage more frequent use.
The current model in schools is to place just a few computers in a fixed position in the classroom. Wireless laptops have the potential of allowing more computers per classroom, thereby allowing large projects that require a machine per user basis to be possible.
The mobile nature of wireless laptops allow computers to be where they are needed, at any time of the day. Because of this, computer technology will be better utilized by teachers and students.
The traditional thin distribution of computer and technology contributes to the lack of use by large numbers of teachers. If teachers don’t have computers - or enough of them, to utilize them effectively in their lessons- then they simply won’t use them. Wireless laptops can help to make the use of computers a reality for all teachers.

 Strategic Deployment
Wireless laptops make it easy to put computing power where it will do the most good and optimize both use and quality of purpose.
o Moving computers where they are needed allows a school to cut its hardware budget while slowing down the purchasing and replacement cycle. Instead of having a few computers in every classroom being used infrequently, fewer laptops can be purchased which will be utilized more often.

 Flexibility
Wireless notebook computers can be used in many different ways to support a lesson, with form following function and purpose.
o Laptops can be deployed across a classroom in many different ways, thereby allowing them to fit the contours of the different rooms without causing any additional cl

  4. 4. Access Points Client Adapters <ul><li>The two basic pieces of hardware involved in wireless networking are: access points and client adapters. Access points are devices which plug into the network and help establish wireless connections to the network through computers containing a client adapter. Wireless client adapters replace the traditional wired network card in a computer. They communicate wirelessly with the access point devices, thereby facilitating access to network resources. </li></ul>
  5. 5. Why Wireless? <ul><li>Wireless technology when paired with laptop computers, overcomes many limitations of the traditional desktop computer. </li></ul><ul><li>Desktop computers have not shown the promised gains in student achievement. </li></ul><ul><li>Laptop computers offer portability and flexibility. </li></ul><ul><li>Laptops, because of their size, allow for a greater number of computers in the classroom. Having a 1:1 student to computer ratio can allow greater benefits to learning and teaching. Access to laptops can also allow for technology rich projects in the classroom without the need for having to schedule separate lab times. </li></ul>

  11. 11. Strategic Deployment <ul><li>Wireless laptops make it easy to put computing power where it will do the most good and optimize both use and quality of purpose. </li></ul><ul><ul><li>Moving computers where they are needed allows a school to cut its hardware budget while slowing down the purchasing and replacement cycle.

  13. 13. Simplicity <ul><li>Wireless notebook computers do not require much in the special effort or understanding, and they are easy and comfortable to use. </li></ul><ul><ul><li>Computer and network reliability has improved and the use of computers has become more appealing. The chance of daily use is now greatly enhanced by their simplicity, comfort, and reliability. </li></ul></ul><ul><ul><li>The equipment is easy to use, which allows teachers to concentrate on teaching; no trouble shooting required. Handing out laptops is not much more demanding than the checking out of library books. </li></ul></ul><ul><ul><li>There are no more cords and cables – which can be troublesome. The simplicity of laptop computers is less likely to cause trouble and teachers with a low tolerance for disorder and chaos will appreciate this technology. </li></ul></ul>
  14. 14. Security <ul><li>Procedures need to be put in place in order to check the laptops in and out of the central storage location. </li></ul><ul><li>Because of their light weight and size, laptops must be kept in a highly secure area as they are being recharged. </li></ul><ul><li>Teachers and students who are permitted to bring laptops to and from school must be advised of the proper procedures for dealing with theft or assault. </li></ul><ul><li>Many schools have opted to purchase insurance for the theft and lost of their laptops. </li></ul>
  15. 15. Laptops Encourage Collaboration Among Students <ul><li>Laptop students work in groups several times a week on average compared to a few times a month before laptops were introduced in their classrooms. Laptop students assume a greater variety of roles in the learning process – students teach teachers as well as do more exploration on their own. </li></ul>
  16. 16. Laptop Teachers Feel More Empowered in their Classrooms <ul><li>Laptop teachers have a greater sense of control over their classroom instruction and management of student learning. Laptop teachers use computers far more often in a wider variety of learning activities than non – laptop peers. Their students use computers more often for data analysis, presentations, writing and research. Laptop teachers also have greater confidence in using technology tools like word processing, e-mail and the Internet. </li></ul>
  17. 17. Future of the Wireless Classroom <ul><li>We will be seeing greater throughput and faster speeds on the wireless network, getting closer to traditional wired network speeds. </li></ul><ul><li>A forthcoming standard, 802.11a, should provide five times the bandwidth of today’s wireless networks, although with smaller areas of coverage from access points. 802.11a is not compatible with the current standard, so new equipment would have to be purchased if that equipment only complies with the 802.11a standard. </li></ul><ul><li>802.11g, yet another standard, should allow for twice the bandwidth of current wireless networks while maintaining the same larger area of coverage of 802.11b. </li></ul>
  18. 18. Final Thoughts <ul><li>Wireless laptops are a large asset to the revolution in information technology learning that is taking place in our classrooms. </li></ul><ul><li>Understanding the pluses and minuses of laptop use are imperative to the successful introduction of laptops in the classroom. </li></ul>
