Networks & Wireless - Week Nine Questions

1.       Explain the business benefits of using wireless technology.

Wireless technology refers to any type of electoral or electronic operations that is accomplished without the use of a ‘hard wired’ connection and is a means of linking computers using infrared or radio signals.. The benefit of utilising wireless technology is cost effective, companies/residents no longer have to rip up buildings or streets or lay down expensive cables. Wireless technology has obvious advantages for people on the move who would like access to the internet in airports, restaurants and hotels.

2.       Describe the business benefits associated with VoIP

Voice over IP (VoIP) uses TCP/IP technology to transmit voice calls over Internet technology. The telecommunications industry has experienced excellent benefits from combining VoIP with emerging standards that allow for easier development, interoperability among systems and application integration.

3.       Compare LANs and WANs

A local area network (LAN) is designed to connect a group of computers in close proximity to each other such as in an office building, a school or a home. A LAN is useful for sharing resources like files, printers, games, or other application. It often connects to other LANs and to the internet or wide area networks. In contrast to this local area network, a wide area network (WAN) spans a large geographical area, such as a state, province or country. WANs connect multiple smaller networks, such as local area networks.

4.       Describe RFID and how it can be used to help make a supply chain more effective.

Radio frequency identification (RFID) technologies use active or passive tags in the form of chips or smart label that can store unique identifiers and relay this information to electronic readers. RFDI tags can cut costs by requiring fewer workers fir scanning items; they also can provide more current and more accurate information to the entire supply chain.

5.       What is one new emerging technology that could change a specific industry

An emerging technology that could potentially change the way in which Wi-Fi access operates is WiMAX, this can solve all of the issues involved with Wi-Fi such as:

-          Small hotspots, and as a result coverage is sparse.

This evolving technology can cover an area of as much as 48,000 square kilometres, depending on the number of users.
