Hi to all,
Could someone please tell me the differences between these two AP families (Aironet 1140 vs Aironet1040) ?
I've seen that the LAP version of the 1040 doesn't support the feature Extended Coverage..what is this feature about? Antenna specifications?
Moreover these LAP could be use in combination with:
- WLC 21XX Series and
- Switch 802.3af compatible (up to 15.4W per port)
Thnx for the support
actually the 1040 supports MIMO , however it supports 2x2 and the 1140 supports 2x3
they both work with the standard .11af power .
i guess the only difference between the two is the the 2x2 ( 1040 ) and 2x3 (1140 ) spiral streams
So as I have supposed the basic difference are the MIMO Streams: 3TX/3/RX on the 1140 and ony 2TX/2RX on the 1040...
but on the CCO a pdf "at a glance" regarding the Aironet AP states that the 1140 have also these features which are not present on the 1040:
- Extended Coverage (any info found on the CCO regarding this...)
- Multimedia (Voice Video)
- Cisco ClientLink (interesting feature for mixed environment g/n and a/n)
- Cisco Bandselect
obviously price came also as a difference ;-)
thanks to all for the replies...
I think I will go with the 1140 Family on the WLC2125 (also if the interfaces are not Gigabit so I won't be able to support full 802.11n but sure to have better performace that traditiona 802.11g)
Just a small correction, the 1140 is 2x3:2 and the 1040 is 2x2:2 ..
T - Transmit
R - Receive
S - Spaitial
You will fine 802.11n with the following flavors:
Cisco Aps support 2x2:2 or 2x3:2. Atheros will have their 3x3:3 chips coming out in April. Not sure what Cisco's road map is to support it. The spatial is your "money". Each spatial equates to 150mb, so you will see 3x3:3 equates to 450 mb.Thats why with Cisco APs and others, you will only ever get 300 with xXx:2.
** EDIT **
Let me add further, 2 on the transmit means you will use no more than 2 antennas to TX on. 3 on the receive means you will use 3 antennas to rx on. The spatial is your streams. if you have a 2 stream AP, that the most streams you will have. AND, thats if your environment is favorable to use 2 streams... Just because it can do 2, doesn't mean it will always do 2 .. it takes advantage of multipath ...
802.11n although by standard could support 600 4x4:4, its VERY unlikely we will see that in the enterprise. Atheros mentioned they will not support development of the 4x4:4 chip. Why you ask ? They said that 802.11ac should be a quick ratification. 802.11ac, you will be able to do 8x8:8, hence GIG over wireless.
