Mikrotik used to present new products at the MUMs but… this time they’ve make and undesirable presentation!

When will it be on sale?
distributors should already be taking orders
The PDF brochure says the wireless card in SXT G-2HnD is Onboard dual chain 5GHz 802.11a/n Atheros AR9280 wireless module. So Does this device uses frequency convertor?
What are the frequency ranges?
No, it was a typo. It has been corrected: http://routerboard.com/pdf/436/SXT-2.pdf
What about frequency range?
This is a 2.4GHz device, there are receive filters that work for outside 2.4GHz range, so everything not 2.4GHz will not work so good. If somebody needs to use frequencies outside 2.4GHz, you can write to support and we can organize some special order for you, without filters.
I see now there is F36n-PRO radio card that can go to RB411. I was thinking on using F36n-PRO radio card and RB411 as AP. As from you above post, if the filters are removed can the SXT G-2HnD work in 3.3 - 3.8Ghz frequency?
Sure. Will work in any frequency between 700Mhz to 10Ghz.
All wireless producers are idiots because they make products for every frequency instead of one for all frequency. I’m sorry but for 24Ghz you need a dedicated device. And also you should read some stuff about wireless first, maybe wireless for n00bs…
Nice rant! 
Does. Sxt g-2hnd antenna supports that range if the filters are removed?
Just curious… it’s my understanding that gigabit ethernet requires all four pairs, and was therefore incompatible with passive POE. How does it work in this model? Are the POE units for this model interchangeable with other MikroTik units?
a special Gigabit PoE injector is required: http://routerboard.com/RBGPOE
RouterBOARD devices with gigabit interfaces still work with passive poe over “spare pairs”. You just need Gbit PoE injector for this to work.
If you set wireless to superchannel mode you can see all the frequencies that is supported by the wifi.
OK, thanks for pointing me to the new accessory, but I’m still curious as to how it works. I was taught that gigabit ethernet required all four pairs FOR DATA; in other words, if you are running gigabit, there are NO “spare” pairs. 802.3af implements POE for gigabit by introducing a DC bias (“phantom power”) over which data can still be superimposed, but then it is not referred to as “passive POE” which requires spare pairs. Thanks for any explanation.
Gigabit uses all four pairs on Cat5E cabling to get gigabit through, Cat6 and above cabling only needs the normal pairs thus providing “spare pairs” for the power.
I understand also you can use the “normal” PoE injectors however it will simply limit the interface to 100Mbps.

Ah! So, Cat-6 cabling will be required in order to use these new units? Thank you.
no 
Well, that’s helpful… not. My previous observation seems to flow logically from all the information in the previous postings. Maybe you can be a little more explanatory about where you think I went wrong.
You can use them with Cat5E and even with the old injectors, however you may find you can only use them at 100 meg speed if you use those cables.
This limit is unlikely to be a major issue in most circumstances unless you are using a multi radio setup or almost all your traffic is one directional.
YMMV

cat.6 is not required for 1gbps connection.
