Elevators are practically faraday cages. The condo I live in is 10
floors, one of the taller buildings in the area, and due to its height,
T-Mobile, Cingular, and MetroPCS rents the cooling tower on the roof for
cell equipment. Even though their antennas are right there on the roof,
once those elevator doors close, my signal reception tanks...

metal cables, motors, etc under the car as opposed to above it.
Just a thought,

Not to mention there is typically a lot of electrical noise in
elevators that could cause substantial interference.

I think the best bet is either an access point at the top and bottom
of the shafts with the antennas pointing towards the elevator, or an
access point on the elevator itself. Only problem is that the wiring
bundle that goes to the elevator would have to modified (you may need
an engineer from the elevator company to do that) and the total
distance of cable needed (depending on number of floors the elevator
travels too) could be longer than the 100 meters max length of ethernet.

OT: Wireless in elevators
I have deployed 300+ cisco 1130 aps and the powers to be are asking
for the spectralink phones to work in the elevators.
Anyone have any experience with getting coverage there?
I’m hoping the elevator will support a direct poe/data connection and
mount the ap right in/on it.
I’m thinking that as you quickly go up/down floors that trying to
associate with passing floors is going to cause issues.
Is one AP at the top of the elevator shaft sufficient?
Any ideas?
TIA
