    CPE510 True Speed

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    Hello i want to know before buying if this product has true speeds, reading at the specifications you can see that it only supports "10/100Mbps Shielded Ethernet Port" So why the 300 Mbps tag?

    Also i bought one year ago a "
    http://www.tp-link.com.au/products/details/TL-WR941ND.html " and the same thing happens, "300 Mbps" with:

    4 10/100Mbps LAN Ports
    1 10/100Mbps WAN Port

    ............................. Really?

    Its a misconception to think you could reach 300 Mbps data speed if the device can deliver 300 Mbps wireless speed. The important factor is AirTime - there is only one sender possible in any shared WiFi channel at the same time. So in order to reach the data speed on the Ethernet port during the amount of AirTIme your WiFi device will get, the device must be able to deliver 2 times the data speed - or even better - 3 times the speed on the data line. As for real speed of data with a CPE510: this depends on many factors such as distance, free LoS, numbers of neighboring devices using the same channel, TPC/DFS requirements in your country and even weather conditions. What's more, 300 Mbps wireless speed would require two free adjacent channels in the 5 GHz frequency band.

    To give you an idea: I could manage real data speed of ~ 58 to 70 Mbps between to CPE510s on a not-so free LoS (two maple trees in between) over a distance of 600 meters.

    So, if im understanding you can get a 58 to 70 Mbps in 40Hz band (double channel) i have a 5ghz n/ac antenna with free internet (no one use it) at a block away from my home (200 meters) this would work for that? right now i have a tp link 54210 but its only G and the signal its not that good when the channels change (because of the people that use the 2,4 Ghz band)

    No, only 20 MHz channel width could be achieved, b/c of radar detection. But data rate was between 58 and 70 Mbps, so wireless speed was probably about 130 to 150 Mbps on the radio link.

    You could try it. CPE510 works best with another CPE510 (or a WBS510) on the other end of the link, but if the other antenna has enough signal strength and receiver sensitivity it probably will work also. 200 meters are not that much for a CPE, but you can use at most n mode with the CPE, not ac mode. It's best to first try with fixed n mode setting and fixed 20 MHz channel width and if that works, you could try 40 MHz channel width. Also make sure there is mostly free line of sight between both antennas. For testing speed, use the built-in iperf test of the CPE (needs an iperf server on the remote site - e.g. a cheap OpenWRT or linux box could work or maybe a Windows computer if iperf is available for it).

    Please share the results with the forum if it will work. Thanks & good luck!
