hi gays,
i m trying to find stable access point client + high power i couldnt find
i was using D-link 900+ amps 1 watt but tooo much problems low transfer rate arround 300kbps 
please guys i m waiting for best soultion you could offer for me
thaNX in advanced
For stable access point and high data rates I would sugest you to use atheros ar 5212 and sectorized (for exaple 14dbi or 16 dbi) base station with nstreme and poling and on the client side ar5212 or 5211 chipset and if you have long links you should use 30 dbi parabloci antennas and on shorter distance you could use 21 dbi antennas .
That was how we have build our network and have up to 8Mbps and could have a connection up to 30 km away from the base station the frequency I am using is 5ghz .
the_time
sounds great,
but you mention just the chipset where can i find this produect currently i m using hardware from http://www.alcon.stc.com
and 30km point to point or point to mpoint?
btw whats is nstreme and poling i want anyone to tell me what is it please
nstreme is a MT proprietary protocol that can use a polling technique to allow clients to talk with the ap. Think of it as a token ring, when a client recieves the token it gets to talk for x amount of time. It helps avoid collisons and speed up throughput, but it also eats up CPU cycles. It also allows for full duplex communications with Nstreme2. You can read more about Nstreme in the MT RouterOS manual.
All clients must be MT and have Nstreme enabled in order to participate in an Nstreme enabled network.
And if you look around on MT website you’ll see they have 802.11a/b/g cards for sale, atheros and prism based. You can also get these from one of your local wireless distributors, try google.com.
The chipset I have mentioned can be found on http://www.mikrotik.com or contact sales@mikrotik.com and if you plan to conect on 30 km then you should use 16dbi sectors and 30dbi parabolic antenna .
thanx alot guys i really admire that new info
