Wireless networks continue to be implemented and utilized in various environments. The technology continues to be improved and is now able to provide cross-vendor interoperability, computing capability over increased distances, and security that can be improved by several emerging solutions

Security

By increasing the number of wireless networks, securing the information that is transferred becomes more and more critical. It is important that security methods deployed for wireless LANs are consistent with the same sound security methods used to secure wired LANs and dial-up access connections.

There are several methods of security that can be used to improve the security of wireless LANs. They include:

• RADIUS or Kerberos based access control.
• End-to-End encryption.
• Password protection.
• User authentication.
• Virtual Private Networks (VPN).
• Secure Socket Layer (SSL).
• Firewalls.

Wireless technology can easily integrate with these security methods as well as others; however, increased attention must be placed on this topic in order for wireless networks to succeed. Security will be a major priority at HEWAC so that the exchange of sensitive and confidential information can be transferred without fear of being lost or stolen.

The future remains bright for wireless technology. As the benefits are realized and as costs continue to decrease, wireless access technologies will continue to flourish.

Wireless applications will continue to evolve as they relate to computing. As society continues to become more mobile, the need for real time information and the ability to access it immediately will become more critical.

Many leading technology companies also recognize the many benefits that wireless technology has to offer and the potential that exists. IBM, Intel and AT&T joined forces in 2002 to create Cometa Networks. The purpose of Cometa will be to provide broadband, wholesale, wireless Internet access nationwide. It plans to provide this service to telecommunications companies, Internet Service providers, cable operators and wireless carriers, who then can offer their customers wireless Internet access.

The wireless Internet will also continue to grow. Dataquest Inc. expects wireless Internet use will grow in North America over the next five years -- from only 7.3 million in 2000 to 137.5 million in 2005.

It is this growth in wireless technology and usage that warrants an organization like HEWAC. An organization to maintain and promote the advantages wireless access can provide to learning communities around the world.
