hi.

RB711 - Supports 1x1 MIMO

How can 1x1 be a MIMO??

well preciselly it should be RB711 - Supports 1x1 SISO, ref. http://en.wikipedia.org/wiki/MIMO. But can you imagine number of questions in this forum about this “new” technology?

even i thought i had to be SISO but then why Mikrotik has been advertising it as 1x1 MIMO?

Can we have some explanation on the 1x1 MIMO concept?

its 2x2 MIMO with chain 1 off on both sides …, what is unclear in this?

2x2 MIMO with 2 chains can be understood as it has 2 connectors for a Antenna made specially for that purpose. horizontal and vertical transmissions at the same time…

what is 1x1 MIMO for?? it has one 1 connector and works just like a standard radio.

depends on what you call a “regular radio”. it does work in compliance with 802.11n, so it’s not just a “regular radio”

there is nothing called 1x1 MIMO
LOL

They aren’t the only ones out there that say it.

Hi,

Take a look at the Modulation and Coding Scheme for 802.11n.

http://mcsindex.com/

You can have 1Tx/1Rx and it’s still 802.11n.

Even with only 1 antenna/1 stream, you are able to push a theoretical maximum speed of 150Mb/s, while on 802.11a with turbo you can only go to 108Mb/s.

I think that the confusion is between 802.11n and MiMo.

Kindly regards,
