I currently have a 2 - 2.2dbi dipole antenna connected to a Cisco 1242AG AP. The AP is mounted on the ceiling in the first floor center of the warehouse where there are many boxes and metal pallet racks. The signal is above average on the first floor but on the second floor it is kind of weak. Is it better to use a higher dbi antenna such as (AIR-ANT2485P-R) patch wall mount 8.5 dbi or should I use the 5GHz which might be better in a warehouse environment.
Thanks in advance
