    CPE510 Ethernet port

    Hi there.

    I'm a little confused about the operation of the CPE units.

    They say they can communicate at 300Mbps, but it is not possible to relay this information because of the 100Mbps limit on the ethernet port.

    Am I missing something here?

    Many thanks in anticipation

    http://www.tp-link.com/en/products/d....html#overview. You should read this. 300Mbps means its wireless speed. It supports 300Mbps in 5Ghz. I think you should know that wireless speed has nothing to do with the Ethernet transmission speed 100mbps.Also refer to this: https://en.wikipedia.org/wiki/Fast_Ethernet

    Thanks for reply, I understand the working of the CPE and ethernet, but I still can't get my head around this...

    Consider it another way. The ethernet can only get data to the CPE at 100Mbps so how can the CPE transmit that data faster than it can get it?

    AirTime 300Mbps under optimal conditions equates to roughly 100Mbps cable...In other words if you can get a link of say 180Mbps between AP and STA, real world airtime throughput is about a third (i.e. 60-80Mbps).

    Many thanks for that.

    The equipment has wireless chip capable of transmitting in theory 300 Mbps, in real field should be 200 Mbps, but the port of 100 Mbps if it is a limitation.
    The device with good line of sight can transmit 80 Mbps to 100 Mbps.

    It's all about AirTIme. To get 100 Mbps over air, the AP must send the data much faster to keep up with this speed, b/c it can't allocate the channel all the time and b/c encapsulation in radio frames adds some overhead, too. Real data speed is roughly 65% of wireless speed in 802.11n mode, so it perfectly makes sense to send data much faster over the air than it comes in on the Ethernet port.
