Aironet 1252 / 802.11n / Outdoor Use over 2.7 km (1.7 miles)

Hi There,


We are planning to use two Aironet's 1252 over an 2.7 km point to point link.

One of the options we have it to install three HyperLink Parabolig Grid 5.8 MHz 27 dBi antennas in parallel for every 1252.


I have some concerns because those antennas are not supported by Cisco. In fact, the most gain of Cisco supported antennas is 10 dBi Yagui for 2.4 GHz and 6 dB Omni for 5.8 GHz.


The question is if the 3x 27 dBi antenna array on each side will work without self interferences and what would be the required separation of antennas to get 300 Mbps over the link.


Has anyone tried something like this with the 1252's?


Thanks in advance for any information.


BR,


Igor Sotelo.

Igor,

Bridging at N rates is not supported. Documentation should be updated on this shortly.


HTH,

Hi Steve,


I have seen the Q&A section for the Aironet 1250:

http://www.cisco.com/en/US/prod/collateral/wireless/ps5678/ps6973/ps8382/prod_qas0900aecd806b7c82_ps6973_Products_Q_and_A_Item.html

states that both root and non-root bridge modes are supported.


About that, may I ask if that means that the bridging can work over 802.11n, but is not supported for regulatory reasons. Or the bridging basically only functions in 802.11 a and g modes.


Thanks for the information.


BR,


Igor Sotelo.

Correct. Sorry my earlier post was not clear. Bridging in only supported on the 802.11a adn 802.11b/g rates. We do not currently support bridging on the 802.11n rates.
