9.4.9 Wireless Network Design

Which of the following best describes a site survey?

A process of planning and designing a wireless network.

Which of the following should you include in your site survey test equipment? ( Select two.)

A tall ladder A spectrum analyzer

Which of the following best describe a spectrum analyzer?

A tool used to determine the noise floor in the desired frequency range.

To optimize your network, you want to configure your wireless AP to use a channel that meets the following criteria: Non-overlapping Low utilization Low interference You performed a spectrum analysis to identify 2.4 GHz wireless channel utilization, as shown in the exhibit. (To read the spectrum analysis, imagine a line coming down from the center of the highest point of each wave. For example, the four waves whose crests are over channel 11 belong to channel 11.) Based on the results, which channel should you configure your wireless AP to use?

Channel 1

What is the least secure place to locate an access point with an omni-directional antenna when creating a wireless cell?

Near a window

You are setting up a wireless hotspot in a local coffee shop. For best results, you want to disperse the radio signals evenly throughout the coffee shop. Which of the following antenna types would you use on the AP to provide a 360-degree dispersed wave pattern?

Omni-directional

Which protocol is well known for its use in the the home security and home automation industry, uses a mesh topology, makes devices act as repeaters, and has a low data transfer rate?

Z-Wave

Your wireless network consists of multiple 802.11n access points that are configured as follows: SSID (hidden): CorpNet Security: WPA2-PSK using AES Frequency: 5.7 GHz Bandwidth per channel: 20 MHz This network is required to support an ever-increasing number of devices. To ensure there is sufficient capacity, you want to maximize the available network bandwidth. What should you do?

Double the bandwidth assigned per channel to 40 MHz.

You need to implement a wireless network link between two buildings on a college campus. A wired network has already been implemented within each building. The buildings are 100 meters apart. Which type of wireless antennae should you use on each side of the link? (Select two.)

High-gain Directional

What purposes does a wireless site survey fulfill? (Select two.)

Identify the coverage area and preferred placement of access points. Identify existing or potential sources of interference.
