Cisco 1142 Non-Mounted

[RadiclDreamer]

How does the radio on the 1142 series orient? Do they have to be mounted on the ceiling, or will it being placed on a shelf be sufficient? I've been trying to get documentation on this but I'm coming up short.

It's a hemispherical antenna. "face towards enemy". Ceiling or wall mount, highest gain is away from the AP. Anything behind the 180 degree plane will suffer lots of loss.

Thanks spidey, that was my suspicion, I just wanted to confirm. Also, I guess its worth mentioning, that if in this instance it isnt easy for me to ceiling mount, so if i were to wall mount, or simply flip it over on a flat surface (cisco logo facing down, directly on a hard surface) Would it suffer any more substantial loss due to the close proximity of the device to a solid object?

Really you'll need to try it and measure, everything else is just guess work.

Thanks for the lead, I found this as well which has been a big help in clarifying some of this. I've had a rough understanding of how to do a lot of wireless things, but this is helping understand the underlying reasons things work the way they do.

Excellent link. Should really clarify where the weak points are on a typical omni-directional antenna.
