Definition

For the purpose of this assignment, the terms $$wireless$$ or $$WLAN$$ should refer to or describe IEEE $802\mathrm{.}11$ networks.

Scenario

As a wireless network engineer, you are tasked with deploying a new wireless network in a multitenant building. The area to be covered is approximately $50,000$ square feet. Your first task, prior to the procurement and deployment of the wireless network, should be to perform a spectrum analysis and site survey. This will help determine the best frequency and channels to be used in the new deployment. A survey reveals that tenants on the floors above and below where the new deployment is to be installed are also using IEEE $802\mathrm{.}11$b$/$g$/$n networks, with many access points on channels across the entire $2\mathrm{.}4$ GHz ISM band. A situation such as this may make the deployment difficult. There is an increased possibility of adjacent$-$channel and co$-$channel interference.

Upon further evaluation, it is determined that the lower band of the $5$ GHz UNII band is not being utilized to any large extent. Since this is a new deployment, you have the opportunity to purchase equipment that will utilize the $5$ GHz UNII band as well as the $2\mathrm{.}4$ GHz ISM band.

Questions to Ask Yourself

$-$ Are any devices limited to $802\mathrm{.}11$b$/$g$/$n capability only?

$-$ Does the network require backward compatibility to $802\mathrm{.}11$b$/$g$/$n$?$

$-$ Does the network need to support guest access?

$-$ What impact would a network using only $5$ GHz $802\mathrm{.}11$a$/$n$/$ac have on the business?

$-$ Is it possible to utilize both frequency bands in this deployment to maximize throughput while limiting interference?

$-$ Is a single channel architecture $($SCA$)$ technology system that will allow for backward

compatibility to existing wireless client devices a possible solution?

These are just some questions that need to be considered prior to making any final decisions on the network to be installed and the equipment to be purchased.

Assumptions

$1.$ Two story building $$ each floor $25,000$ sq$.$ ft; See attached floor plans

$2.$ Building is occupied by $3$ different companies

$3.$ Company on $2$nd floor use Toshiba Satellite laptops $(802\mathrm{.}11$b$/$g LAN Card$)$

$4.$ Company on first floor use Panasonic cordless phones for office communication

$5.$ Company on first floor routinely hold public training session in a large conference area

$6.$ See attached spectrum analyses

Your Assignment

Write a research paper explaining your proposed wireless installation plan. The topics covered should include types of access points, antennas, placement of gear, wireless networks $($bands$,$ frequencies, channels, etc.$),$ and potential project costs. Use your imagination but also conform to the above assumptions and what you have learned in the course thus far.

The Details

The final paper should be size $12$ font, single$-$spaced, and a minimum of $2$ pages long. The paper should include wireless hardware placement or other diagrams where appropriate.
