Aironet 1140 and 1250 series WLAN solution

Unanswered Question

Good day,


I am looking for a wireless solution to be intergrated into an existing LAN.  It is a 3 story building with many wall and segregations seperating rooms etc.  I want to enable wireless capability throughout the building.  I was looking at the Aironet 1250 anf 1140 series as possible soltuions. I looked at the directional and omnidirectional antennas options. Should I get like one 1250 with omnidirectional antennas for whereever has the most clients and rooms closely together and 1140's with directional (hallways and similar etc)  and omnidirectional (other floos and scattered rooms) respectively.  Also I want to use one SSID throughout. Is this possible and does it need to be configure on both clients and AP's or only on AP's. I want clients to connect seamlessly wherever they are in the building.  Is this solution good? Any advice is welcomed. Thanks in advance

The difference between 1140 & the 1250 AP is the design functionality.  The 1250, like all the 1200 series, was designed for wide open spaces:  theatres, warehouse, hangards, etc.  Thus the need for a metal enclosure, adaptable antennaes and slightly more transmission power.  The 1140 is designed for an office-type environment:  cubicles, compactors, offices, etc.  Because the 1250 has more transmission power (with both radios operational), you need at least 15.4w to 20.0w of PoE power (or power INJ4). 
The 1140 can operate using standard PoE of 15.4w or power INJ4.


You can configure the same SSID to all APs.


I recommend that before installing your APs, consider a proper Wireless LAN Site Survey conducted to know WHERE you install your APs, HOW MANY and what particular model of the APs to use.


If you want to consider using 802.11n, you need to configure WPA2/AES or open authentication.


Because 802.11n you want want to investigate if your APs could be connected to 1000BaseTx.

Should be fine.

Ok.  With regard to mulitple AP setup with same ssid.  Are there options in the AP console for this like essid or something or do I make standalone with same settings so clients just reauthenticate when in different zone. I would like it to be seamless.  Any links for this type of setup with the aironet series or advice. Also I read about Standalone and Controller based.  I may use between 4 and 6 AP's, should Standalone fine to use? Thanks in advance
