Develop a wireless network plan for a building $50,000$ square feet catering to two floors and two different companies. You perform a spectrum analysis and site survey that reveals that tenants on the floors above and below where the new deployment is to installed also using IEEE $802\mathrm{.}11$b$/$g$/$n networks, with many access points on channels across the entire $2\mathrm{.}4$ GHz band so there is an increased possibility of adjacent$-$channel and co$-$channel interference. Upon further evaluation, it is determined that the lower band of $5$ GHz is not being utilized to any large extent. You now have the opportunity to purchase equipment that will utilize $5$ GHz band and $2\mathrm{.}4$ GHz$.$

The topics covered should include types of access points, antennas, placement of gear, wireless networks $($bands$,$ frequencies, channels, etc.$),$ and potential project costs.

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

compatibility to existing wireless client devices a possible solution?

Assumptions:

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

$2.$ 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

$6.$ Company on $2$nd floor has $34$ cubicles

$7.$ Company on first floor has $15$ offices, a large conference room in the center, and a server room.
