deepak,
when moving from 18dBi to 21dBi, the gain in the end is only 3dB in front of the antenna.
On the sides of the antenna, there will be a coverage decrease.
Also, ensure that your downtilt & azimuth are facing the indoor you want to cover. Try different settings, you might get some interesting reflections that could help covering the indoor area.
regards.
