Re: REPEATER FOR BRIDGE

Hi ,

A) Bridge can be made Access Point but Access Point can not be mad Bridge

B) In case of Access Point , there are two mode , Root and Repeater .

If you put AP in repeater mode , ethernet port is disabled . Repeater is

use to extend the wireless coverage ( or to extend the cell where you don't have wired connection ) .

Disadvantage of puttting AP in repeater mode is throughput reduces but half .

You can have chain of 7 repeater .

Example

Lan ----Ap(root) ---AP(repeater 1) ----Ap ( repeater 2) ---->

If you observer that AP ( root ) is only the AP connected to backbone or wired net .

Now if you can connect wired net to all AP than better to put all AP in root mode

example

Backbone wired net

------------------------------------------------------------------------------------------

Ap1(root) Ap2(root) Ap3(root)

NOw , in case of bridge you can convert it in AP mode or repater AP mode .

If you have bridge in AP mode or repeater mode it bahves as above design .

Bridge has other two modes Root Bridge and NON ROOT Bridge .

Design 1 :

Bridge ( Root bridge ) ------RF ------Bridge ( NON ROOT BRIDGE )

Above is very basic design , two bridges , one root and other non root .

depending on distance and antenna you can cover up to 25 miles .

Design 2

Bridge ( Root ) -------Bridge ( Non root ) ---------Bridge ( Non root )

Now if you want to connect bridges in one continous chain than you can put the bridge in non-root ( which is like repater in bridge mode ) .

Now VERY CAREFULL , YOU CAN NOT DO as designed below

Bridge ( root ) -------Bridge ( repeater ) -----Bridge ( Non root )

Above design is wrong and will not work .

If you have hub and spoke you can do like

bridge 1( non root ) --------Bridge ( HUB ) ROOT ------Bridge ( non root )

Or

Bridge ( root ) -----RF ---Bridge ( non root ) --Wired --Bridge ( root ) ----Bridge ( nont root )

Now saying all this you can have

bridge ( root ) --------bridge ( non troot ) ---Lan --AP -----Wireless clients

Re: REPEATER FOR BRIDGE

So can you have

LAN === Bridge (root) <----->200m<----> Bridge (AP mode) <--> Wireless clients

Re: REPEATER FOR BRIDGE

Sure..that design will work..

Re: REPEATER FOR BRIDGE

Bridge ins AP mode can not talk to Bridge in root mode .

You can have

Lan bridge ( root ) -----------Bridge (non root with clients ) --Wireless clients

OR

Lan --bridge ( ap mode )----------Bridge ( repeater mode ) ---Wireless client
