Mixing 1200 WAPs and 350 Bridges and Root 350 Bridge Antenna Question?

You guys have helped me here alot, and I have two more questions.

I just want some verification from more experienced people about my proposed setup.

We have 4 buildings and I am planning on the following wireless setup.

Building #1 - BR350 Root

Building #2 - BR350 non-root

Building #3 - BR350 non-root

Building #4 - BR350 non-root

All non-root 350s will connect to a switch located in each building. Each

building will have at least 2 - 1200 APs.

I can mix and match the 1200AP and 350s with both 802.11a and 802.11b clients??

For the Root 350, the correct antenna to use would be a omnidirectional

antenna ? And for the non-root 350s I use a directional antenna?

Thanks for all info

Jim

Hi Jim

You are on right direction , Center ( hub side ) needs to be root with OMNI DIRECTION and all spoke will be non root with DIRECTIONAL ANTENNA

Antennas - General

Antennas ship with basic hardware to mount antennas (such as U-bolts), but not the mast itself.

Basic mounting hardware is included with all antennas (except patch, which mount directly to wall).

Keep bridge antenna cables as short as possible (significant effect on range/transmission rate).

If possible, use fiber and transceivers to connect Bridge to LAN (lightning doesn?t travel over fiber).

Cables are not plenum-rated.

Use the calculator tool for bridge antennas/cables.

Antenna needs to be polarized in the same manner for

proper operations ,

There are Two planes of RF , E plane and H plane and

they are 90 degree from each other

Horizontal polarization is best for transmissions over water, since vertical polarizations exhibit a 180 degree phase shift and result in multipath pro

blems at the far end of the circuit.
