Use the exhibit as a reference.

Given:
– In your regulatory domain, a Tx Power Level of “1” is equivalent to 17 dBm.
– For every integer increment (e.g. from 1 to 2) to the Tx Power Level, the AP’s transmit power is halved.
In units of mW, what is the actual transmit power for an AP configured at a Tx Power Level of “4”?

Given: You are evaluating the theoretical and real-world RF gain benefits of transmit and receive features
introduced by 802.11n with MIMO. This exercise allows you to quantify the feature’s value in a real-world
environment.
What is the maximum theoretical signal gain of chip-based TxBF and MRC (as features) when compared tothe same AP using only a single antenna for transmit and receive (effectively simulating a 1×1 chip)?

What RF math formula should be used to convert an RF value in units of dBm into a value of mW?
*NotE. “dBm” in the formulas represents the known dBm value

Why does a frame transmitted at 1 Mbps have a greater usable range than the same frame transmitted at
54 Mbps?

What is the purpose of Friis transmission equation [(LdB) = 20 log(d) + 20 log (f) – 27.55 ]?

What type of pattern matches the 12 dBi antenna displayed in the exhibit?

What antenna connector type is displayed in the exhibit?

What is a radome?

The exhibit illustrates the azimuth and elevation for what type of antenna?

You deployed an AP and installed its antenna, and you now need to set the AP transmit power. Given a
desired EIRP of 21 dBm, and an antenna gain of 5.85 dBd connected through 25 feet of cable with a loss
specification of 4 dB/100 feet. Assuming that there is no significant loss from the connectors, what should
be the transmit power level for this AP?
