I'm up the creek the content filter here won't let me mention.
I've an Aironet AIR-AP1252AG-A-K9 and a smallish three-story, 9-unit, wood-frame construction condo building:
The wired network runs fine, but I want to supply 802.11g and n to all. The switch does POE, I've a power injector, and have configured the 1252 no problem. The two radios in the 1252 will support six antennas - three 2.4ghz and 3 5 ghz) - but I'm clueless as to what to buy or what to locate them. The roof is easy, as is the ceiling of the basement garage: both are already wired with Cat 5E. Locating the WAP anywhere else will require additional wiring that I'd like to avoid, but I'm not averse to hanging upside down by my feet in order to wire antennas, if only I know which antennas to put where.
Of course since the job is measured in hundreds rather than hundreds of thousands of dollars, my local Cisco partner in Seattle won't return my calls.
Antenna advice would be much appreciated. I've spent a week becoming familiar with the issues, but am still not confident. It seems likely much fussing will be involved, and that I might make a false start or two equipment wise, but I'd at least like to increase the odds of getting it right as quickly as possible.
Let say I go with your #1 suggestion: two WAPs with one AIR-ANT2451NV-R each, one in the center of the roof, and the other in the center of the garage ceiling. That means half the roof unit's signal is being broadcast into space, and half the garage unit's into the ground, right? The remaining two halves should still penetrate the building?
Don't forget that the if you mount the AP correctly (Cisco logo pointed downward towards the floor) the signal goes DOWN to the floor and UP to the floor above it. If you mount it on the ceiling, then I'd like to ask if you have anyone working ABOVE the building (nice view!)
Wouldn't some directional solution provide more usable signal?
With such a confined space? I wouldn't use directional unless you plan to shoot the signals over 2 kms.
Also, your #1 idea leaves potential capacity for four additional antennas - a 2.4 and a 5 on the roof, and another pair in the garage. Is there anything I do with that to increase the likelihood of good coverage and high bandwidth?
Ahhhhh ... here's the beauty. The 2451NV is recommended for 1250, 1260 and 3500e because it has SIX pig-tail (RP-TNC) plugs: three for 2.4Ghz and three for 5.0Ghz. So one antennae unit can be pluged in to each radio antennae. Nothing more.
