I'm looking for professional devices to build point to point.

I'm looking for professional devices to build point to point. Please
give me name of brand device. Thanks.

Thanks LLoyd but I am looking better devices or new brand becous I
must build wireless for company (money) so this product must be less
popular but device must be great.

1.Distance 5km
2. 54Mb/s
3.This device should be work 99%a year.
4.Power max 200mW. 5 GHZ 802.11a

If he can live with 48 Mbps at his end point, the PS2 will work fine.

At the 54 Mbps radio speed setting, the end point experience is only 24
Mbps. If he uses turbo mode, he can double it without sacrificing range
as the receiver sensitivity for 54 Mbps and 108 Mbps is the same, its
just that turbo uses a wider bandwidth aggregation.

90% uptime...wow, that means a daily annual average of 2-1/2 hours
downtime. No matter, the PS2 with internal 19 dBi antennas will give
him at least 25 dB fade margin for as little as around five minutes
daily downtime.

all the answers so far have suggested 802.11 wireless gear.

if you really need just point to point - maybe you should go and talk
to a local carrier about a link.

they may have point to point fixed microwave support - but if they can
rent you ethernet / dark fibre or SDH do you really care as long as
you get enough bandwidth at good enough reliability and price point?

What limit?

In Poland you are allowed to use up to a 1W EIRP in outdoor applications in the
channels 149-161 (5.725-5.850GHz).

I have deployed hundreds of Ubiquiti's Nanostations and Powerstations but for
this application I will favour a custom solution using Mikrotik boards, Ubiquiti
radios and MTI integrated antena enclosures. Ubiquiti integrated solutions have
very nice hardware but the software tends to be buggy, even compared with
Mikrotik's RouterOS (much much more capable BTW).

As example you can use a RB411AH routerboard, add a SR5 radio and mount it in a
MT-900007 integrated enclosure with MT-485002 23dB antenna. With this setup
you'll be able to establish connection at 36Mbps while staying into legal limits
dialing down the radios' power to 10dBm.

If you want to connect at 54Mbps then you'll need separate enclosures and 32dB
antennas.

Also you can substitute the board for a RB433AH to be able to install additional
radios/antennas and use Mikrotik's Nstreme Dual for full duplex communication.

Thanks - that is very interesting - even though
I did not ask the question

So in the U.S the limit would be at what???

Ok, that answers my question as to what limits in place.
