150Mbps Outdoor Wireless Access PointBy Juha Saarinen, Auckland | Tuesday, 28 August 2012
TP-Link’s TL-WA7510N is a flexible access point with multiple operating modes and a long reach. It uses 802.11a/n wi-fi in the 5GHz band, for increased performance and less susceptibility to interference – the usual 2.4GHz band is very busy these days.
The admin web interface provides full control over network parameters but the device was a bear to configure, requiring rebooting after changes. Nothing I did would make it pick up an IP address via DHCP on my LAN, and I had to use a static one instead.
Housed in a sturdy, light-grey weatherproof case suitable for outdoors deployment with power over Ethernet, 4kV lightning protection with grounding, and external aerial connector, the TL-WA7510N features a 15dBi dual-polarised antenna and 500mW transmission power. This, TP-Link says, is enough to maintain a stable wireless signal “ranging multiple kilometres”.
And, the TL-WA7510N does seem to provide good reach: after setting up the device so that it pointed towards a field roughly 750 metres away, I was able to connect to the TL-WA7510N from there via a Samsung Galaxy 10.1 tab that showed three bars of wi-fi signal strength. The tablet was able to receive data 12-15Mbps and send at 8-10Mbps with WPA-2 PSK encryption.
The 150Mbit/s promised for the TL-WA7510N is too optimistic considering the Ethernet port runs at 100Mbs. What’s more, selecting New Zealand as the region stops the TL-WA7510N from using 40MHz bandwidth, only half that, and the 802.11n speed is set to 65Mbs instead.
In other words, the TL-WA7510N goes the extra mile but not at the speed promised and is difficult to configure, which is a shame as it retails for an affordable $165-$180: far below its $229 RRP.
TP-Link is distributed in New Zealand by Anyware Computer Accessories.

"The 150Mbit/s promised for the TL-WA7510N is too optimistic considering the Ethernet port runs at 100Mbs"
This comment is incorrect. the 150Mbit/s is half duplex, meaning the full duplex speed speed is 75Mbit/s. The 100Mbps LAN port is more than sufficient as it is 100Mbps full duplex.

From the vendor's specifications:
"Complies with IEEE 802.11a/n, wireless speed up to 150Mbps"
Please take a look at what the vendor says before you you jump to conclusions.

The Wireless 802.11 standards are measured in Half-duplex. Where as Ethernet standards are measured in full duplex. So if you take full-duplex ethernet, the LAN port is actually 200Mbps. I'm not jumping to conclusions, I just know what I'm talking about.

I meant to say in that last statement "If you take Half-duplex ethernet, the LAN port is actually 200Mbps".
