Small base stations became popular in the 5G communication era.

The 5G communication network will change the architecture that relied heavily on large-scale base stations in the past, and the large-scale use of small-scale base stations will allow telecom operators to flexibly construct the network in the most cost-effective manner, thereby increasing network density and coverage, and achieving better than 4G technology. Higher transmission rate and network capacity.

The rise of ultra-high-resolution video streaming, cloud services, and leisure and entertainment services, as well as an increasing number of wireless devices, including smart phones, tablets, and programmable environments for communication between machines. Estimated data for the next 20 years The transmission volume will grow ten thousand times.

To meet these needs, Nokia Networks, a telecom solution provider, believes that 5G will be a scalable and flexible service system that can provide Gigabit with close to zero latency at critical times and locations. Experience.

In addition, 5G has a higher peak data speed, which increases the data rate of "every place", and reduces the latency to one-tenth, allowing users to enjoy a quality of experience that is at least ten times higher than that of 4G.

In The era of 5G mobile communications, it is estimated that the types of use cases and related applications will be more extensive, including video streaming, Augmented Reality, different data sharing methods, and various machine-type applications , Such as vehicle safety, various sensors and real-time control, etc.

After 5G is introduced in 2020 and fully operational in 2030, it must also be able to flexibly support new applications that we have not yet understood or do not know.

In addition to using more traditional wireless access frequency bands below 6GHz, 5G will also use a large amount of spectrum between 6G-100GHz. These frequency bands have different channel characteristics. Therefore, the use of these spectrums requires more than one new wireless
