What is the coverage range of 5G base stations?
Due to the high frequency and poor signal penetration of 5G, the coverage radius of base stations is generally about 100-300 meters, and the number of 5G base stations is more than twice that of 4G!

This blog will introduce fiber optic cable basic parameters and optical fiber: dispersion, attenuation, bend radius, structure, sheath material, bandwidth, attenuation coefficient, insertion loss, etc.
There are nearly 200 fiber optic cable factories in China, but most of them have single products, no independent intellectual property rights, low skill content, and weak competitiveness.
Replacing all existing copper cables with fiber optic cables can now achieve a maximum bandwidth of 16M per household. Applications such as IPTV, network video, video phone, image communication, and home monitoring management have been implemented, and fiber optic cables have become a trend for households, making them widely available.
From LPO to silicon light, from coherent sinking to coherent upper limit, from FTTR to 5G, how does optical communication develop in 2024?
Plastic optical fibers are particularly suitable for FTTH due to the characteristics of thick core diameter, easy coupling, no need for fusion or welding, light weight, good flexibility and bendability. At the same time, they have anti-corrosion, moisture-proof, shockproof and explosion-proof functions, and are resistant to electromagnetic interference and radiation. They have strong confidentiality, safety, and anti-interference capabilities, decay to a constant value, and do not change with transmission status.
China 5G package users have reached 1.3 billion, and ARPU has also increased by 0.4% from 48 yuan. However, 5G has not seen the rapid growth in user traffic seen in the 4G era.
5G base station is the core equipment of 5G network, providing wireless coverage and realizing wireless signal transmission between wired communication network and wireless terminals. The architecture and form of the base station directly affect how the 5G network is deployed. Since the higher the frequency, the greater the attenuation during signal propagation, the density of base stations in the 5G network will be higher.
The power consumption of a 5G single station is 2.5 to 3.5 times that of a 4G single station. The increase in AAU power consumption is the main reason. And the current full load power of a single station is nearly 3700W, and the existing network power supply and supporting facilities need to be expanded in advance.
the single wave capacity of 400G for short distance transmission has gradually matured, and it is expected to achieve large-scale commercial long-distance transmission by 2024.
Both GPON and EPON belong to passive optical networks and are widely used in FTTH. Nowadays, most households are connected to EPON and GPON, achieving the integration of telephone, broadband internet, and IPTV networks. A single fiber optic cable is used to solve the problem of making phone calls, accessing the internet, and watching TV. In the early days, there were many EPONs, but now they are mostly GPONs.
The internet slow may be happen with many reasons: Wifi capacity, frequency band, network patch cord, and modem, application size, router speed, etc.
