Range (AP to Client)
The –A domain AP to client link budget in 2.4 GHz band is limited by upstream. That is, the upstream has
lower system gain, and therefore, the decision factor will be upstream.
Cell sizes for AP to Client in 2.4 GHz for different AP1552 models can be decided by picking the lowest of
the following two:
• AP to Client distance in the 2.4-GHz band (from Table 22: Outdoor 11n AP-to-Client, at 2.4 GHz: 9
Mbps Data Rate (–A domain), on page 78)
• Half of the distance between AP to AP on the 5-GHz backhaul (from Table 20: Link Budget Comparison
for the 5-GHz band in -A Domain, on page 75)
Because most of the clients available are 2.4-GHz clients, we recommend the cell size taking 2.4 GHz values
into consideration (see Table 23: Lowest of AP to Client and Half of AP to AP Backhaul Distance, on page
79).
