and 5 Ghz will be used. Roughly how many APs (rounded to the nearest whole number) are needed
based on client count?
B tbh, if we assume each AP can handle clients on both bands simultaneously, then for 30 users on 2.4 GHz (max 15 per AP) you’d need 2 APs, and for 70 users on 5 GHz (max 25 per AP), around 3 APs. So combined, that’s roughly 3 APs total if dual-band APs can share load efficiently, but 5 if single band. Since the question hints at a split but doesn’t clarify single or dual-band APs, 3 seems like the best estimate for dual-band capable setups.
If I break it down, 30 users on 2.4 GHz and 70 on 5 GHz, and assuming typical max clients per AP are about 15 for 2.4 GHz and 25 for 5 GHz, that means you’d need at least 2 APs for the 2.4 GHz users and about 3 APs for the 5 GHz side. So combined, that’s around 5 APs total. But if APs are dual-band and can handle clients across both bands simultaneously, maybe the load balances differently. Anyone else think the client distribution per AP might be more flexible, or should we stick strictly to those typical maxs?
B/C? If 100 users split 30/70, that’s 30 on 2.4 GHz and 70 on 5 GHz. Assuming each AP can handle about 15 clients on 2.4 and 20 on 5 GHz, you’d need 2 APs for 2.4 GHz (30/15=2) and 4 APs for 5 GHz (70/20=3.5 rounded up). Since AP count is based on the band with the highest number of required APs, it looks closer to 4 total. So, I’m thinking C fits better than B or D here.
Option C seems reasonable, but are we assuming each AP supports a fixed number of clients evenly split between 2.4 and 5 GHz bands? More detail on AP capacity per band would help.
