Antenna for AP1200?

Hi,

i will like to reduce the ap1200 coverage by around 1/3 of the normal range for an auditorium that will house around 400 people.

The purpose? So that I can substain the bandwidth.

According to the ap1200 specs, the antenna mentioned in the range is the 2.2dbi one. Is there any suggestion as to which antenna I should get? Maybe one with less dbi or the 2.2 as mentioned by cisco?

Another question, if i reduce the transmit power (the range effectively), does it affect the data rates as well?

Re: Antenna for AP1200?

To convert dBi to dB (the number you actually want to use to determine range) subtract 2.15.

2.2 - 2.15 = .05, so there is no real gain from the 2.2 to begin with.

To reduce range, reduce the transmit power at the AP. Data Rates will drop at the edge of your coverage area.
