Believe me, you should choose CPE510.
5GHz is always better than 2.4GHz for outdoor communication of long distance when line of sight is ensured.

I have two CPE510 working as a point to point link at a distance of about 13 Km. So far so good.

And never choose TL-WA5210G for >2Km, you can see others' comments on this model in this forum.

Hello ZETM,
Good to know that you have made a link of 13Km between CPE-510 pair at LOS. May I know whats the aggregate throughput you get? I set up a link of AP-Client mode with only 3.4Km but the other location is on a thick foliage, while the other location is 1500ft above ground, yet, I can only get a signal strenght of -88 to -89..very poor

That will be too low. The foliage and obstacles cause huge attenuation.


My link is pretty clear. The AP is 100 meters high on a hill, while the client is on a platform at the other side. They maintain very good line of sight, clean Fresnel zone, no obstruction in the way. I got SNR > 18db, although signal strength is -95dbm.

At the beginning I was using the old firmware, where the Ethernet aggregate throughput was > 35Mbps. Later the new firmware released which supports extra channels. The throughput is reaching 45Mbps when I pick up a out of band channel such as frequency 6000MHz.

Thats very cool! my CPE510 has a version of firmware 1.0.0. DOes it have a latest firmware than what I have now?
Thank you.
