Part I: Internet Access Methods
Currently, there are 5 ways to access the Internet: telephone line access, fiber optic broadband access, passive optical network, wireless network, and access to the electrical network. In addition to the wireless network, the other four methods require a broadband line to access the
home. Many home users do not have such conditions, and the wireless network can easily access the Internet with just two steps: turning on the device and inserting a SIM card.
Wireless networks are further divided into 2G, 3G, 4G and 5G networks. 2G and 3G networks cannot meet the needs of home Internet access due to their low speed, while 5G network terminal equipment is expensive, although its speed is fast, and its price is usually that of 4G CPE equipment. 5-10 times. Another point is that the construction of 5G networks in many countries and regions is not yet mature, and small cities and remote areas have not yet achieved 5G network coverage. In short, based on the analysis of convenience and economy, 4G network is more suitable for families who need to build a network cheaply and conveniently.
There are two types of devices that share the Internet through the 4G network, LTE CPE and LTE MiFi. LTE CPE belongs to system integration product. It uses the LTE mobile communication system to provide the return transmission channel and WiFi achieves coverage, which is a device that converts the high-speed 4G signal into a WiFi signal. Similar to MiFi, its AP function and router performance are stronger than MiFi and can be accessed via various mobile terminals such as tablets, smartphones and laptops at the same time.
After a thorough analysis, it is not difficult to see that 4G LTE router equipment is currently the best choice to build our own home network conveniently.
Part II: How to choose a suitable LTE CPE?
Next, let’s discuss how to choose the right LTE CPE. We choose between Internet speed, number of access users, coverage, product reliability, stability and ease of operation, as well as price. SmileMbb LTE CPE devices are representative of various brands. Different CPE devices are designed to meet the Internet access requirements of different occasions and applications, including indoor, outdoor, and industrial CPE routers. Here we will take the SmileMbb LTE indoor CPE XMC1841 model as an example.
