You can buy adapters for expensive Cisco and other Wireless equipment to do exactly this. The power is supplied across an RJ45 cable from a box situated in the patch cabinet I assume the receiving box has to have the correct ports to be able to use this.
Okay... let's start with this: RJ45 is the plastic head on the end of the cable. The cable itself is either Cat-5 or Cat-6. Secondly, no... A router can not be powered by the Cat-5/6 cable. There is not enough in there to carry the power supply needed to run the router.
