Hi @adarsh1783 

Have you tried to search the CPE products in our official website or in forum? You can consider CPE210 or CPE510 to install the point to multi points connection. For the common scenarios of CPE, please refer to this link.

 

And when you search the CPE in official website, you will find the set up video of the CPE. For CPE210, please refer to Download for CPE210 | TP-Link

For CPE510, please refer to Download for CPE510 | TP-Link

 

Here are some instructions about how to deploy the CPE: Long distance wireless connection concerns when using outdoor access point | TP-Link

Please note that whether the point to multi points connection can be installed successfully is not guaranteed, which will be affected by the actual environment.

Sorry for the delay in response.

Thanks for sharing the two documents for setup, those are pretty helpful. 

I have read about the CPE210 and CPE510. Most of the documentation mentions they are for long-distance use, but it's unclear if "long distance" means more than 500m-1km or more than 5km-10km. I could get the CPE510 but am unsure if it will provide 300Mbps over a 2km distance.

To double-check, using the speed of light (c = 3x10^8 m/s) and frequencies (5GHz for CPE510 and 2.5GHz for CPE210), and a distance (d1 + d2 = 1.8 km), the maximum value of r is approximately ~5m for CPE510 and ~7m for CPE210. Is this calculation correct? Since we only need r(1-0.4) height above the obstacle, we require ~3m for CPE510 and ~5m for CPE210.

Based on these calculations, will I be able to get 300Mbps speed with either CPE210 or CPE510 over a 2km range? Or is there a difference in practical scenarios?

I read online that the CPE210 can have interference issues, and there might be other factors. That's why I'm sharing all these details and asking for suggestions. I'm fine with getting either the CPE210 or CPE510, but once I buy, there are no returns. So, I'm doing all this analysis.

Regarding PtMP, what are the key factors in deciding if PtMP is possible? Is there any documentation about this? I thought if we get a CPE that supports PtMP, then we should be able to set up PtMP.

  @adarsh1783 What hasn't been mentioned is what is between the access point side and the client sides?  Is there a clear line of site or are there trees, buildings, hills, etc in the way?  Also, how much signal noise is there?  Is there lots of other wifi, cell tower, or industrial buildings nearby?  If this is a clear line of site with minimal rf interference, get yourself 3 CPE510's and set them up on a bench before you deploy them.  The higher you can mount them, the better they will work for you but don't go broke trying to compete with a cell tower.  Also, in a perfect scenario, you will get almost 100 mbit on a speed test.  I've found that the 210's can 'see' through trees and brush better but the 510's are less prone to rf interference.  Both products are reasonably priced as well and don't require much maintenance once deployed.

You can achieve this setup with a simple point-to-point wireless bridge for the connection between the main device and the two receivers (CPEs). Ubiquiti's NanoStation or  no text similar devices can provide reliable connectivity over distances with sufficient speed for your needs. For file sharing, consider setting up a basic network-attached storage (NAS) device accessible to all users.
