At present, Beijing Unicom's NB-IoT network construction, combined with spectrum characteristics, technology maturity, chip modules and other aspects, Beijing preferred 900M for IoT deployment, and at the same time open 1800M NB network on-demand, to achieve dual-frequency coverage, to create Terminal types cover the most complete NB-IoT network.
In the target planning, the first phase was as of May 17, 2018, before the International Telecommunication Day, Beijing Unicom has completed the construction of approximately 5,000 900Mhz NB networks; the second phase, by the end of 2018, nearly 10,000 NB-IoT narrow bands were achieved. Networked base station opened.
At the current stage, Beijing Unicom has achieved full-area coverage of the entire urban area and suburban county, combined with actual demand in key areas, industrial parks, science and technology parks to increase the coverage density. In addition, Beijing Unicom will launch the recruitment of IoT partners in the near future. plan.
