3 advantages of small cell networks

We have all encountered the inconvenience caused by network blind spots. Macro remote radio units (RRU), also known as macro cellular networks, are usually deployed in centralized locations and can cover densely populated urban areas. As the number of people using the macro cellular network exceeds the limit, the system signal will be overloaded and weakened. To increase network capacity in high-utilization areas, manufacturers need to supplement existing macro-cellular networks with the help of small-cell networks.

The following are the three major advantages of using a small cellular network:

1. The small cellular network can be used by multiple users. Small cell networks can make full use of available licensed or unlicensed spectrum, and are more efficient in using spectrum than macro cell networks. Small cell networks limit the number of users using the same base station and open the same frequency band to other users in other areas. Figure 1 illustrates the degree of demand for more different frequencies when a macro-cellular network is to provide services to an area. Small cell networks can reuse the same frequency because these frequencies serve different small areas.

2. No more signal loss. 4G covers frequencies below 6 GHz, while 5G covers frequencies from 6 GHz to 30 GHz, or even 300 GHz. However, the disadvantage of higher frequencies is increased attenuation, making the signal transmission distance shorter and unable to pass through walls or other obstacles. Small cellular networks can take advantage of a wider spectrum; because of their small size and compactness, they are very suitable for installation in urban areas and are closer to users to prevent signal loss.

3. Data transmission speed is faster. Small cellular networks can be installed closer to the user, and the signal transmission distance is shorter, so the data transmission is faster and the delay is reduced. Figure 2 shows the effect of the distance between a small cellular network and the user ON the speed of signal transmission and reception. Due to the reduced latency, the time required for downloading, streaming, sending and receiving text messages, and Internet searches will be greatly reduced.

The above are just three of the many advantages of deploying 5G using small cell networks.
