While first signs of commercial LTE deployments appear on the horizon, the standardization organizations are working already on next steps in technological enhancements that shall provide the user with full 4G experience. It looks like the market of 4G technology will be much less fragmented compared to previous generations of mobile communication systems. There are just two candidate technologies remaining with 3GPP LTE-Advanced and IEEE 802.16m. Considering the huge industry support for LTE the vision of an almost unified global 4G standard might not be out of reach anymore. This paper provides some insight into the latest activities on 4G standardization in 3GPP, in ETSI as well as in ITU.
