The 4G LTE modem is a kind of terminal equipment of the Internet of things. Under the background of the continuous advancement of industrial informatization, the market demand for 4G LTE modem is also growing. It has many advantages, such as wide network coverage, low fees, accurate and timely data transmission and so on.However, in the process of using 4G LTE modem, there will be many problems. For example, the connection of 4G LTE modem is unstable, which will cause the loss of data transmission and greatly affect the progress of the project.
The 4G LTE modem connection is not stable in the practical application process, mainly due to the following reasons.
It is used in remote mountainous areas.
The signal environment in remote mountainous areas is often very poor, and the 4G LTE modem connection is often unstable. The countermeasure is to choose a high-gain antenna to increase the acceptance of network signals, or to install a serial data line and place the 4G LTE modem in a place where the network signal is strong.
4G LTE modem has incorrect parameter settings.
In the area of strong network coverage, the situation of incorrect parameter setting is the most. The 4G LTE modems of most manufacturers generally have 4G LTE modems that prevent disconnection. In practical applications, users can set the heartbeat packet time interval to be less than the detection time to avoid disconnection.
The ring network signal is too poor.
For example, underground parking lots in cities, mountain libraries and so on, the shielding of obstacles makes the network signal very poor. The solution is to extend the antenna to a place where the signal is good.
The quality of 4G LTE modem itself.
At present, there are many 4G LTE modem manufacturers on the market, and the product quality is also uneven. The 4G LTE modem with poor quality has natural defects in hardware and network settings. The solution is to choose high-quality products from reliable manufacturers.
The above four points are the application and solutions of 4G LTE modem connection instability. The actual situation is analyzed in detail.
