Why does the Antenna range differ a lot between 1728 and 2506

derobbacher · ‎09-24-2009

Hello,

I'm wondering about the documented approximate range of these two Cisco antennas, that differ a lot.

Can someone explain the big difference in range between these two antennas that have both the same antenna gain of 5.2 dBi and beam width 360Â°H and 38Â° V

AIR-ANT1728 Indoor antenna

Indoor range at 54 Mbps: 114ft, 35meters

AIR-ANT2506 Outdoor antenna

Range at 54 Mbps: 0.21miles, 340meters

Can we use the 2506 also for Indoor applications ?

Please advise and explain.

Thank You in advance.

I would assume that the outdoor range is measured in free air ie with no obstacles where the indoor range is indoors and takes account of walls etc.

I may have seen something on the test methodology but it may have related to clients rather than antennas.

The 2506 is fine indoors as it says in the installation document

However the range will be the same as the 1728 as the RF characteristics are the very similar.
