1240 : Bridge mode, Outdor Antenna

Unanswered Question
Feb 9th, 2009

Hy,

until now we use only DLink WLan Components.

Now we must do a Wlan Network with Cisco.

We have to use 2 1240AG for an outdoor Wlan Bridge (ca. 70m).

My question are,

1. is it possible to use the 1240AG in Bridge Mode ?.

2. For an External Antenna: must i use 2 Antennas or only one ?. (The 1240AG have 4 Ports ??)

Greetings

Markus

I have this problem too.

Hi Markus,

1. Yes, you can set one AP as Root-Bridge and the other one(s) as Nonroot-Bridge.

2. The 1242AG has 2 antenna ports for the 2.4GHz Band and 2 for the 5GHz Band.

I would suggest you to use the 5GHz Band, because there are several interferences in the 2.4 GHz-spectrum like microwaves or bluetooth. And the 1242 uses DFS (Dynamic Frequency Selection) in the 5GHz-spectrum. This means, he checks for channels which are not used by other APs befor using them by himself. This avoids interferences with other Access points, especially in outdoor areas.

Oh, and you only have to use one antenna. We used the AIR-ANT5195P-R for a similar installation like yours, and it works for distances of 150m and more.

Greets,

Sebastian

Hi Sebastian,

thanks for your Answer.

Think we will use one 2,4 GHZ Antenna, because it's already there.
