Factors for Selecting The Appropriate 4g Lte Modem

4g lte modem adopts FDD-LTE or TD-LTE technology, realizes 4G network through local serial data, and realizes wireless long-distance data transmission and data interaction with remote public network servers. These are mainly used for. Before you buy, remote data collection and remote control projects must complete the task of choosing a 4g lte modem so that you can choose the right 4g lte modem. So what factors should not be ignored when choosing a 4g lte modem?

The brand is a symbol of quality and craftsmanship, and vice versa. The design and craftsmanship also demonstrate the power of the brand.

Some brand manufacturers, in order to fight a price war, depress the quality. It's hard to believe that the quality of this 4g lte modem is guaranteed, and you can imagine the failure rate when using this 4g lte modem.

Some manufacturers make 4g lte modems very cheaply. They just encapsulate the communication module into the 4g lte modem, not the underlying protocol. Customers also need to use the underlying at command set to use, which is very inconvenient. Secondly, on the premise of ensuring product quality, the next step is to check whether the function of 4g lte modem meets the application environment of the project.Is it used for data transmission or SMS transmission, or both?

Some manufacturers' 4g lte modems cannot be used for SMS transmission, and even SMS transmission packages are not large enough for most projects. In addition, some projects want to use the network access feature in addition to the transparent transport feature. In this environment, you can choose a 4g lte modem with a network port or a wireless transmission terminal with 4g lte modem and router functions.

3. A device that selects a communication data volume with a large capacity and fast communication data will inevitably have an advantage. 4g lte modem has a downlink rate of up to 100Mbps and an uplink rate of up to 50Mbps, providing customers with high-speed Internet access and wireless data connection functions, which is suitable for large-scale data transmission applications such as serial camera image transmission. The ping value of the 4G system is less than that of the 2G/3G module, and the response time from the module to the receiving server is shorter, so it is suitable for applications that require higher response time, such as remote alarms.

4. Interface selection Select a terminal interface, such as a full-duplex RS232 port or a half-duplex RS485 port. The corresponding interface is easy to operate and has relatively powerful functions, which reduces the trouble of poor contact. Of course, the more interfaces you have, the more benefits you get.

5. Choice of carrier It is also important to choose the right network operator that supports 4g lte modem, depending on the environment in which you are using the project. The mobile version of 4g lte modem cannot be used in an environment with only China Unicom signals.

If you neglect to choose a networked system at the time of purchase and find that the signal is not correct in your environment, you will waste unnecessary time and cost on your next purchase. The above five points are about the five factors that can not be ignored when choosing 4g lte modem.
