4G is the fourth generation of cellular network technology, succeeding 3G and designed to support all-IP communications and broadband services, enabling a variety of data-intensive applications. [1]

2021年12月24日 · 而在4G/5G移动通信中，通常使用RSRP或RSRQ来评估信号质量。 - **SINR（Signal-to-Interference-plus-Noise Ratio）**：信号与干扰加噪声比，它是衡量接收到的有用信号与其背景噪声（包括干扰信号）的比率，SINR越高...

This map represents the coverage of 2G, 3G, 4G and 5G mobile network. See also : mobile bitrates map and Globe Mobile, Smart/Sun/TNT Mobile, Dito Mobile mobile networks coverage.

The following indicators are used to determine the quality of a 4G LTE signal. The charts indicate rough guidelines as to what constitutes a particular level of quality, ranging from excellent to unusable. To avoid performance issues none of these values should be in, or dip into the red.

CellMapper is a crowd-sourced cellular tower and coverage mapping service.

2024年2月12日 · Under optimal signal conditions, you should see minimum speeds of 100 Mbps - this ensures you’re getting true 4G. Maximum 4G speeds cap out at 1000 Mbps down, and 500 Mbps up. So, if you get anything approaching these speeds, you are on the true cutting edge of 4G, even though the specs were laid down over a decade ago.

2020年1月21日 · Introduced in 2019, peak capacity is said to be 10 gbps (gigabits), making it a hundred times faster than 4G technology. The roll out of 5G depends on the installation of equipment. Massive MIMO technology will be installed on top of the existing 4G infrastructure.

2024年12月3日 · In this post lets review the most basic and important tasks to improve SINR in 4G networks (Signal to Noise Ratio). Control coverage of the cluster. All cells should have a coverage as planned. Remove all overshooting cells causing pilot pollution. Each cell should have a clear coverage footprint without overlapping coverage of other sites/cells.
