2013年是LTE发展史上极为关键的一年。GSA 8月发布的LTE演进报告显示,目前全球有443家运营商正在投资LTE,其中204张LTE网络已经开通商用服务。在204张商用网络中,20张为TD-LTE商用网络,其中约9家运营商选择了融合组网。虽然LTE FDD网络较TD-LTE发展早,但随着TD-LTE技术的成熟,运营商建设4G网络可选择其中一个制式的LTE;也可以选择搭建两个LTE,搭建TDD/FDD融合网络。
2013 is an extremely crucial year in the history of LTE. GSA released in August LTE Evolution report shows that 443 operators are currently investing in LTE around the world, of which 204 LTE networks have opened up commercial services. Among 204 commercial networks, 20 are TD-LTE commercial networks, of which about 9 operators have chosen to converge networks. Although the development of LTE FDD network is earlier than that of TD-LTE, as TD-LTE technology matures, operators can select one of the standard LTE systems for building 4G network. Alternatively, two LTE networks can be set up to build TDD / FDD convergence network.
