Another detail I forgot to include is the fact that the elevator is an older style, metal cage, so it is not condusive at ALL to wireless signals.
I’m looking at NFSS DSSS and FHSS and at this point, I’m not certain which I should pursue for the wirless network camera located in the elevator.
Any suggestions?

I’ve heard that DSSS is far more reliable, is much better for wireless hopping, and is faster because of its implementation. What I have read indicates this is only a viable solution for a 2MBps network, and I want much more, of course. Any suggestions? Is there a source for information like this that I haven’t yet found?

I guess the point i was trying to bring out originally was kind of overlooked. I want to get a strong wireless signal into 8 floors of elevator shaft. Mounting points in the shaft are extremely limited. The best place to mount would be the cieling of the shaft, but about 2 feet above are generators and motors powering the elevators and they create a lot of magnetic and frequency-limiting fields.

I assume a sight survey was done before installation. You are correct the generators will produce unwanted interference along with the metal cage itself. I manage and maintain several locations around the country that use wireless access points in conjunction with Symbol MC9090g scan guns for shipping purposes, it seems the older the wharehouse the more problems we have. With that being said I have had good luck with my wireless infrastucture using a company called Ryzex Inc, you can google them they have always delivered when I was in need. They will of course ask if a site survey has been completed and will want one done if not already completed. Hope this will help you out.

No official site survey has been done.
I will consider this option, But I think I have a workable solution. There is a retractable cable unit. If I run some cable there it should work fine. Plus it will be hard wired.
I will have to find RJ45 cable that can bend endlessly though.

I have found continuous flex RJ45 cable. I think this will solve my problem.
