Describe the wireless solution you would recommend for EACH

Describe the wireless solution you would recommend for EACH of the following three organizations, and give the rationale for your decision using at least three criteria for that choice. There could be a combination of these options for an individual organization. Central University- CU wants to add a wireless overlay network to one 20,000 square foot floor in its business school building. They have a bid for 802.11g access points at a cost of $100 each and a bid for 802.11n access points for $300 each. Students will buy their own computers, most of which will come with 802.11n NICs. What would you recommend, and WHY?

Solution

Approximate range of 802.11g access point = 125 feet

Area Covered by 802.11g access point = (22/7) * 125² = 15625 sq. ft(<20000 sq. ft)

Approximate range of 802.11n access point = 230 feet

Area Covered by 802.11n access point = (22/7) * 230² = 52900 sq. ft(>20000 sq ft.)

Thus the area covered by 802.11g access point is less than the floor area, and the area covered by 802.11n access point is greater than the floor . So we need two 802.11g access points and the total cost would be $100 * 2 = $200, and guess what its still cheaper than a 802.11n access point, $300. Though the performance increases drastically when we use a single 802.11n instead of 802.11g. But all students can\'t use the wireless network if 802.11n while if 802.11g is used the students using computers having 802.11n NIC have backward compatibility with 802.11g access point.
