China may not see 4G for another 2-3 years14
Wei stated that the country hopes to expand its current network of 220,000 TD-SCDMA base stations to 400,000, and then upgrade those units to LTE TDD before offering 4G licenses. He anticipates that process will take three years to complete.
State owned China Mobile is a driving force behind LTE TDD deployment, but Wei also cited handset and chip vendor support as a barrier to entry. He said, “We need their active participation, to speed up development of the commercial trials.”
