You have designed a WLAN with a plan for 87 APs in a large office building. The customer has informed you that the budget is not as large as they hoped and they can only purchase 53 APs. What action should be taken?
A.
Simply increase the output power of the APs by 30 percent to accommodate the smaller number of purchased APs
B.
Perform a complete redesign of the wireless network and inform the customer if some original requirements cannot be accomplished
C.
Remove as many walls as possible within the facility so that the signals can travel a greater distance
D.
Use only 2.4 GHz radios because the signals can be received at a greater distance
If the number of APs changes due to budget constraints, a complete redesign is required to reevaluate coverage, capacity, and performance expectations. Increasing transmit power or relying on 2.4 GHz is not a valid solution, as it can result in co-channel interference and poor roaming.
From CWDP-305:
“A design is based on specific coverage and capacity requirements. Any major change, such as reducing the number of APs, requires a full redesign to determine the impact and ensure that business requirements can still be met.”
