Sort of like how a microwave can effect cordless phones / wifi.
The issue is not that people will transmit on the wrong frequency as a system this huge has to have a lot of oversite by the FCC but rather the power that the towers are putting out. A powerful enough signal will naturally become wide enough that is saturates the spectrum nearby. Interference would be possible as a signal from 20k +miles won't have the power a tower from 5 miles would. It all depends on the sensetivity of the receiver. Band pass filters would pretty much make this "issue" a non issue.

I would also like to note that cell phones already use the L-band spectrum. The difference is that the carriers with 4G will just take up more space.
