Finally, Happy New Year 2014.
I had done my 1Km wifi setup and the outcome very impressive.
the mission is to link my house unifi to my mother-in-law house:
[unifi]-->[unifi router]<--->[NSM5]<- - - 1km - - ->[NSM5]<-->[router]<--wifi-->[devices]
Location: KL/Selangor
Check list:
1) ubquiti nanostation M5 X 2 units (RM350 each from advancedatan.com)
2) CAT-6 23AWG LAN cable X 2 (RM30-70 find in lowyat)
3) WIFI router (i use cheap Tenda router) to share the internet
4) Optional* cheap water pipe to shield the cable (70cent/ft)
5) Optional* steel pipe about 5ft (RM 12)
6) Optional* cement and sand (RM 5)
item #4 #5 #6 are for outdoor setup
NOTE* please use good quality CAT6 cable, 23AWG, not 24AWG for long range because the PoE (power over ethernet) will lost due to cheap and thin cable and causing the NSM5 up/down all the time. my first failure is using cheap 40m CAT5.
Actually it is quite simple....
1) Configure your NSM5, please follow this tutorial, it will save your time alot!!!

Note 1* After watching the youtube, please go to Advance tab and set your distance from 0.6 miles default to something else greater, I set 27Km for my house NSM5 and 10Km for mother-in-law house NSM5 else you got not enough throughput to link both distance.
Note 2* Please set your wifi access password as the tutorial ask you not to set, I'm using WPA2.
Note 3* I am using 5Ghz, not 2.4Ghz wifi for less interference.
2) mount the first NSM5, make sure it is line of sight.
3) build your base to mount the second NSM5, just mix some concrete and sand into those "CNY" plastic container and stick you steel pipe inside, wait for two days.
4) make sure everything is setup properly and bring your NSM5 to your destination for setup.
Note1* Make sure the LAN cable is gently pass through the pipe
Note2* Use some aluminium foil to wrap the exposed LAN cable
5) adjust your NSM5 to get best signal, I just agak agak only...
6) setup your 2nd wifi router and share the internet out, you are done.
The result is superb!!!
The links speed is from 240Mbps to 300Mbps from airOS, RSSI is -64dbi for 1Km, which is better than my router signal from living room (unifi router) to my house toilet.
when I benchmark unifi speed from my mother-in-law house, I get full speed. wow
----------update 2-------------
The legality of this setup in malaysia.
Just check with skmm spec and it is legal as my frequency is 5.7Ghz and ubiquiti NSM5 having max throughput of 600mA which is less than 1 watt under 5Ghz category.
http://www.skmm.gov.my/skmmgovmy/files/att...nts/WTS_SRD.pdf
The maximum EIRP for Class Assignment Wireless LAN type devices;
Item Frequency Bands Max EIRP (Watts) Max EIRP (dBm)
1. 2400 MHz to 2500 MHz 500 milliWatts 27 dBm
2. 5250 MHz to 5350 MHz 1 Watt 30 dBm
3. 5725 MHz to 5875 MHz 1 Watt 30 dBm
----------update 3-------------
Here is the picture showing medium (heavy?) rain and I can achieve -64dbi with 270Mbps-300Mbps speed. wifi quality remains same during rain.
----------update 4-------------
Didn't found any issue (03-Mar-2014), noticed something, during heavy download, the speed will drop to 180Mbps and rise up again if download stop.
----------update 5-------------
Almost 2 years, this setup didn't create any issue, network is smooth and consistent.
