According to analysts, China became the world’s biggest smartphone market this year. So it’s little wonder that the nation’s operators are working fast to roll out 4G networks.
As we have reported earlier, China Mobile’s Beijing branch (Beijing Mobile is upgrading its TD-SCDMA (3G) network to TD-LTE (4G). Nokia Siemens Networks is working with them to upgrade existing 1.9 GHz frequency TD-SCDMA technology to TD-LTE, has successfully completed the nineteenth site upgrade from TD-SCDMA to TD-LTE, and conducted the first TD-LTE call on Beijing Mobile’s upgraded field trial network. Our dual mode 1.9 GHz and 2.6 GHz single site TD-LTE solution will help substantially reduce site costs for China Mobile.
Nokia Siemens Networks’ base station uses software-definable multiple radio technology, so the upgrade from TD-SCDMA to TD-LTE is achieved quickly and easily through a software update.
To see how it was done, have a look at this short video about the Beijing Mobile field deployment, which provides insight into the benefits of the dual frequency single site TD-LTE solution:
