BT AC11 Dual Band WiFi Extender 1200: What is the performance?

BT has launched this 802.11AC WiFi extender to match the Home Hub 5. It should be great but BT's website has no performance data. The 1200 suggest 1200MBPS. However, unless the product has sufficient internal or external antennas (<4) and waveforming it may only produce a fraction of the possible performance. Before spending, I am interested to know if it offers the real performance improvement the AC monica suggets.. (I currently have a 500 series plug in extender.) Has anyone tried it or has anyone at BT have the tech data that is normally published.

Re: BT AC11 Dual Band WiFi Extender 1200: What is the performance?

Products advertised as AC1200 will be a single antenna solution.

 

Maximum 300Mbps on 2.4Ghz band (operating as 802.11n, 802.11ac does not operate on 2.4 Ghz) assuming short guard interval and 40 Mhz channcel width.

Maximum 867Mbps on 5Ghz band assuming short guard interval and 160Mhz channel width.

Re: BT AC11 Dual Band WiFi Extender 1200: What is the performance?

Yes what the manufacturers do is to add together the 2.4 GHz and 5 GHz max speeds (in this case 300 Mb/s and 867 Mb/s) and advertise that as the speed of the device (1200 Mb/s is close to 1167 Mb/s after all - well it is in the eyes of the manufacturer!!!).
