UBNT LiteAP AC 120 Access Point Configuration and Mounting Techniques (Urdu/Hindi)

Hello friends, How are you all Many of you (ISP operators) might be using UBNT Lite AP AC 120 degree or planning to upgrade your old M5 system with this one This is ChaCha Mechanic and today we’ll discuss configuration and mounting of UBNT Lite AP AC Lite AP AC is a great and cost efficient device for wireless ISP operators Its Ultra lightweight radio and sector antenna combined weighs even less than a pound which greatly helps while mounting and alignment It provides 120 degree coverage and you’ve to get 3 of these to have a full 360 degree coverage some friends prefer a single omni-directional antenna over 3 Lite AP AC sectors but a single Omni alongwith its radio costs almost equal to 3 Lite AP AC sectors however, in terms of efficiency… 3X Lite Ap Ac sectors may prove super efficient as single Lite AP AC can achieve thruput of upto 450Mbps that means 3X APs can provide a total thruput of more than 1Gbps however, single Rocket M5 can do upto 150Mbps and Rocket AC or lite can handle upto 450Mbps Now, Lets have a look at its configuration like all other UBNT devices Lite AP’s default IP is also 192.168.

1.20 after putting the device ON, and connecting it to your PC or Laptop Open you web browser and try to access device’s IP address bypass the security warning frist of all we’ve country selection I’m gonna select Brazil as they allow larger spectrum than Pakistan mean’s you have more frequencies to opt agree and continue There’s an “Upload Backup Configuration” option available here If you’ve already got a saved configuration set you can avoid configuring every single setting and can use this option to restore that config file and save your time so, once you’re done with your configuration…

Make a backup of that and whenever you need to re-configure you may use that backup to save your time press continue and you’ll see login page previous M5 devices had “ubnt” as default password which had to be changed during setup but these AC devices require setting custom password at begining so we’ve to set our password here after saving password we get device’s Dashboard You’ll get device’s status here which precisely all info of your device As I’ve told earlier.

You must upgrade firmware of any wireless device especially UBNT devices before configuring or using them firmware up-gradation enables device to operate at latest standards so first of all, we are gonna upgrade its firmware click on the settings Settings has got 4 tabs Wireless . .

. . . . .

. . . Network . .

. . . . .

Services . . . and . .

. System To check current version of firmware, we’ll go to system tab here is your firmware section and the current firmware version is 8.5.9 I’ve already checked ubnt.com/downloads and I found version 8.

6.1 which I’ve already downloaded to upload that downloaded firmware, I’ll choose Upload and select the downloaded file Uploading has started after completion, device will check files compatibility & integrity if it finds the file compatible, it will prompt “Upgrade” option but if you’ve uploaded some incompatible or corrupt file, then it will prompt “Error” after pressing “Upgrade” device will start upgradation process this process may take 3-5 minutes power interruption during upgradation process can damage your device so take special care that device must be kept “ON” while this process completes on completion of upgradation, device will restart login again after login you may confirm the upgradation now its firmware version is 8.6.1 you may feeling difference in current and previous firmware as setting categories tabs in old firmware were at the top of the page While current firmware is showing then here at left side So now we are ready to configure Lite AP as an Access Point (AP) first of all we’ll go to “wireless” tab where we can adjust its wireless properties You can see that it has five options in wireless mode If you’re planning to connect a single AC station with this device you’ll select Access Point PtP (Point to Point) if you’re planning to connect multiple AC (only) stations you’ll select Access Point PtMP (Point to Multi Point) airMAX AC In this mode M5 devices won’t connect with your device Select this mode only when you’ve to connect all AC stations i.e.

Litebeam AC, PowerBeam AC or LOCO AC etc but if your network consists of only M5 or or M5s with some AC stations…. you’ll select Access Point PtMP airMAX Mixed mode in this mode your lite AP will connect to all UBNT’s airMAX devices either AC or M5 but non-airMAX devices of other companies won’t connect after that we’ve got Station PtP Mode you shall opt this If you want to use this device as a single station of some other AC device but the Access Point in this case, must be set as “Access Point PtP” and finally there is “Station PtMP” you’ll opt this if you want this device to be station of any PtMP Access Point As we intend to use this device as an Access Point for multiple stations & those stations may include both AC and M5 devices.


So we’ll set this device to “Access Point PtMP airMAX Mixed” Mode In new firmware, we’ve got this information feature where our device tells us its max capability of range & clients according the the mode and settings we’ve opted recently like you can see it’s informing that we can connect maximum of 85 clients and at max distance of 22.5 km with our current wireless settings Set your SSID (Service Set IDenty) 40Mhz channel width should work better but if your site has an occupied spectrum, you may opt for 20MHz Channel Width here you can choose device’s frequency try to set a frequency which has least interference These devices also have a site survey tool like M5 devices which can list frequencies being used at your site but AC devices come with an additional feature that surpasses the M5 a spectrum analyzer bar is projected all the time on its Dashboard using this analyzer bar, you can easily find the vacant frequency it would be much better to choose frequency after mounting the device as you can get true picture of interference only after mounting the device at required location so try to configure the device after it is mounted at desired point you can set a password in wireless security section so no unwanted or alien device could connect to your device but perhaps you don’t need that if you’re already using some firewall or authentication server I see here a new feature of “Wireless Network Protection” I honestly don’t have any information about this but my instincts are compelling me to enable it under that you see MAC ACL (Access Control List) using this you can allow your wanted or block unwanted mac addresses TDD framing is a control of Time Framing thru which..


Device allocates separate TX time time to every station as per its data load requirement you should keep it flexible so your device can adjust the transmission time according to changing requirement If you want to isolate the clients…

. enable the “Client Isolation” this won’t let any client to connect to other client on the network but if you want to access some station while being at a different station or you plan to install IP cameras and you want those cams to show on some other client’s location you’ve to put “Client Isolation” off I’ve already discussed “Calculate EIRP” in my previous videos If you desire to control your device’s power manually….

turn this option off but if you want the device to calculate for optimal output power you should enable this option I’ll turn this option off and maximize output power so my device is detectable at maximum distances Keep “Auto Adjust Distance” ON so that your device can automatically adjust the transmission delay according to farthest station this control does not affects device’s range at all so do not try to extend range of your device thru this option leave “Max Data Transmission Rate” at Auto So your device can auto adjust max data rates according to quality of every station separately.

Its also better to leave “Data Rate Module” Auto Now go to “Network” Tab Keep Network Mode at Bridge so every client gets its own separate line allocate Static IP and change the gateway according to your network put “STP” and “Auto IP Aliasing” ON so that multiple networks are accessible thru this device Now go to “Services” Tab enable “Discovery” & “CDP” (Cisco Discovery Protocol) Now head towards “System” Tab here you can name your device this name will show in your Cisco or Mikrotik’s neighbours list We are almost done with our configuration by pressing “Save” all the changes we be saved this device will now be accessible at it new IP address login again & make sure your settings are in effect Our Lite AP is ready to mounted now but its not necessary that you configure your device before mounting You may configure it after its mounting Mounting of any wireless device plays a key role in its performance you can get good results out of an average device just by mounting it perfectly but can also spoil the performance of a high performance device by not mounting it correctly I’ve witnessed PowerBeams at a mere distance of 2 km and Lite AP efficiently working at 15km always seek feasibility of any link before getting started on it basic factor of feasibility is LoS (Line of Sight) that I’ve explained in my prevois videos for feasibility of any UBNT link, you may use UBNT airlink calculator second most important factor is to keep the signal attenuation and reflections at mounting site/s for example if you’ve got a tower to mount on never clamp the device directly to tower’s pole as your tower is metal and also grounded it will absorb and ground the transmissions of wireless devices this weakens the signals thus reducing the signal strength always use stand offs between tower and devices so that transmissions are less prone to absorption and make their way to connected devices this will surely improve your links and if your device has a nearby large reflecting surface like signboards or building etc which poses such an angle that causes reflected signals to receive at your device this will cause signal shadows and your device may receive same signal more than once this will cause errors in transmission as well as reception, and device’s CCQ will be ruined lesser the signal attenuation and reflections, more efficient your links will be You can watch my video on “How to boost performance of your antennas” (Click above link) I hope this will help you alot If you learnt something new today hit “Like” You may put your questions in comment section and please share this video with your friends if they need this information press subscribe so you can get my future videos till next video, take good care or yourself
