Question about 802.11g coverage using a 1252 / 1140 Access Point

spapageorge · ‎06-15-2009

I was wondering if using an AP such as the 1252 or 1140 will increasse 802.11g signal coverage, or are these radios going to be the same as using an 1130 or 1242?

If the 1252 / 1140 AP's do increase the signal coverage will the client be able transmit back to the radio, or will there be problems.

Are the answers different when using an autonomous or unified solution?

1140 & 1250 APs can do 802.11 a/b/g as well as the new Draft N 2.0.

Aside from physical appearance, the difference between 1140 & 1250 lies in what it's designed for.

1140 is designed for deployment in an Office-type environment: walls, cubicles, compactors, etc. The 1250, however, is designed for industrial use: wide open spaces, all-metal enclosures (very heavy weight) and has more powerful radio transmitters (thus you need 19.0 watts of power).

In light of current technologies, I would recommend deploying AP's with Draft N.

Hope this help.

1252 / 1140 will both provide additional coverage for legacy g clients. It is about a 20% increase for a/g coverage, the AP's are able to hear the clients through the receiver design of the AP's, the radios will use all three signals received on the antennas and combine them. This allows a and g clients to both transmit/receive at a higher signal level. Cisco does however recommend a one-to-one replacement of a/b/g AP's to n in order to achieve the highest rates available.
