IS-3120 Lab 5 Questions and Answers
1. A Wireless LAN or WLAN provides wireless network communication over short distances using radio or infrared signals instead of traditional network cabling.
2. Three advantages of WLAN are:
a. Provides more capability than wired 10/100 Ethernet connections, allowing enterprise applications to be mobilized thus increasing productivity.
b. Provides mobility and availability, in order to hook up to the network, you only need to open your laptop and push button to enable the wireless network. You do not have to worry about cable length or finding the plug.
c. WLAN is cheaper and quicker to deploy, adding users is just a matter of configuration. It does not involve making physical connections. Wireless technology saves significant amount of money on the cabling cost and labor.
3. Three advantages of WLAN are:
a. Wireless networks are less secure than wired networks, both in terms of access and in terms of user information. Because the information to and from the computer is broadcast instead of traveling over a wire, it is much easier to intercept.
b. Devices will only operate at a limited distance from an access point, with the distance determined by the standard used and buildings and other obstacles between the access point and the user.
c. WLAN is limited number of users and lower bandwidth, Wireless transmission is slower, less efficient and less reliable compared to wired networks. Backbone is in most cases are wired.
4. 802.11g operates at a maximum raw data rate of 54 Mbit/s, or about 22 Mbit/s net throughput.
5. IEEE 802.11ad "WiGig" is the fastest wireless standard. The new standard can achieve a theoretical maximum throughput of up to 7 Gbit/s. with a data rate up to 6912 or 6.75Gb/s.
6. To access the routers configuration, open a web browser and type in the wireless routers web address, the web address is usually provided by the manufacturer or type 192.168.1.1 and enter the administrator user
