Building to building Bridge link using Aironet 1300's
We have a requirement to link two adjacent buildings that are about 20-metres apart over a public road. I need some advice on what the best solution will be.
Initial thoughts are a pair of Aironet 1300's configured as Wireless Bridges but the antenna type and where to mount them is confusing me. Will the internal patch antennas be enough for this or will we need external antennas? If so what type - directional or? Do the AP's need to be mounted externally or can we simply mount them internally facing each other through windows? What do we need to be aware of regards signal overlaps and interference etc?
What looked like a simple setup seems to have opened a can of worms....
Look under 'Table 4. Antennas for the Cisco Aironet 1300 Series Outdoor Access Point/Bridge with RP-TNC Type Connector'.
Both AP1300 and the antenna can be installed indoor. You need to wall-mount the antenna facing each other from each building.
Since the distance is only 20m, you can play around with the transit power to control the signal distance.
As for overlapping channel & probability of interference, do a simple site survey (can use freeware NetStumbler) and make sure your antenna does not mounted near equipment like microwave, or any equipment that produced high frequency noise.
