Wireless-fp "Ce, Ceee, eC, eCee, eeCe, and eeeC"

Sun Jul 06, 2014 7:15 am

Whenever I select one of the odd ones aside from eC or Ce, it says its not supported. What are they, wider channels? Exentions for use only with 802.11ac cards???? Anyone know?

C is 20MHz contol channel. In 11n you have Ce and eC with 40MHz. In .ac channels can be wider.

Could someone please post the descriptions of each one of these. I can't find a cheat sheet.

Also if someone could reveal a mini-pci car for 802.11ac that will work with routerboard it'd be appreciated.

As far as I know there is no 802.11ac product for RouterBoards. The "eeeC", etc. channels are simply support in RouterOS for future 802.11ac products.
In 802.11n mode:

eC = 20/40MHz-ht-below
Ce = 20/40MHz-ht-above

You can see why they needed to rename the values otherwise they'd look a bit like this:

20/40/80MHz-ht-some-above-and-some-below!!

That makes sense. The AP rolls back to 20MHz for compatibility, right?

Yes. To the "C"-Channel.

What about (Ce | Ceee | eC | eCee | eeCe | eeeC ) ???

eC mean Extend Channel below : 20Mhz?
eCee mean Extend Extend Channel below : 40Mhz?
eeCe mean Extend Channel below : 80Mhz?
eeeC mean Extend Channel below : 160Mhz?

or how?

and why Ce and Ceee but there is no Cee ?

C- is center of frequency
e - is extension channel


example : frequency is 5100 and in eCee will be see (5080-e,5100-C,5120-e,5140-e)

i have as of now good speeds on the new SXTac using NSTREME...

shifting to NV2 is really bothersome...

Each letter denotes a 20MHz channel section.

C: is where the Channel's main frequency is set
e: is where the rest of the spectrum "sub-channel" is distributed

There is no "Cee" because that would equal 3x20MHz combined channels to make a 60Mhz channel, Mikrotik currently only has 20/40/80 channel width available for AC.

If the antenna is has 2 spatial streams (dual-chain) then you will see 2x 80Mhz, not 2x160Mhz, equaling the equivalent of 866Mbps link speed. Single chain (1 spatial stream) = 433Mpbs link speed.

Hope this helps!
