Wireless Bridge Recommendations

I am looking at replacing our DWL-2100AP with more current wireless bridges. The distance between the two will be around 750 feet.

We are currently using external antennas with the coax connection so the new units should support this type of connection.

Any suggestions?

Hi,

for wireless point ot point bridge, I reckon that you can't go past mikrotik routerBoards.  The embedded routerOS software supports a very cool tunnel system called 'Ethernet over IP' which delivers a mechanism to build a truly transparent bridge between ethernet ports on each end of the link.  The result is what is essentially the same as a cable connecting the two ends (except for the speed of course!) none of that problematic pseudobridge technology that most of those garden variety d-links, linksys and netgear etc.

and if you want speed - there are some routerBoard models with gigabit ethernet ports, so usinng the latest 802.11n wireless modules, you can build a wireless point to point link delivering in excess of 200 megabits real (udp) throughput!

This is the official routerBoard site: http://www.routerboard.com
The manufacturuer and software developer is Mikrotik: http://www.mikrotik.com

If you are in Australia, try DuxTel: http://shop.duxtel.com.au
They even offer a ready-to-go 5GHz link kit:  http://shop.duxtel.com.au/product_info.php?cPath=23&products_id=54

Cheers!

We ended up going with Proxim wireless equipment. The Mikrotek routerboards are good however they do not offer any WLAN.

what????  any routerboard with minipci slot supports WLAN!  Several models support 3, or even 4 wireless interfaces! :-D

take this one for example:

http://www.routerboard.com/index.php?showProduct=107

It sports NINE gigabit ethernet ports and up to THREE wlan interfaces - at under $200 for the base unit, I don't know of any proxim that comes even close! ;-)

Cheers!

Our ISP which deals with Mikrotek informed us that the application we are trying to set it up as Bridge to Bridge over long-haul this units would not suffice hence why we ended up going with the Proxim equipment

hmm - then your ISP is quite wrong about that <sigh>

We use mikrotik for long distance point to point all the time, and personally I would say that there is no better bridge.  We make a true transparent point to point bridge with mikrotik routeros that delivers 802.11n 2x2 MIMO >200 megabits over short distances (1Km), > 100 megabits over medium distance (10Km), > 50 megabits over longer distances.

With mikrotik routerOS, you can even do full duplex wireless links, PLUS they have built in QoS so you can run vlans over the wireless with priority on realtime traffic.

All this with true transparent bridging - none of that psuedobridge crap that so many other wireless vendors try to sell you.  The idea, if your ISP can be bothered to check up on it, is that routerOS supports a tunnel technology called 'Ethernet Over IP' which creates an ethernet-like link across any network (even across public internets!)  So we use this eoip link to tunnel across the wireless, then bridge that tunnel to the ethernet ports at each end.  The result is a wireless bridge that is technically indistinguishable from a cable (except for wireless speeds of course!)

I'm utterly amazed that your ISP told you such bunkum <sigh> - too late now, I suppose, so it goes ;-)

Cheers!
