At present, there are 5 ways to access the Internet: dial-up access by telephone line, optical fiber broadband access, passive optical network, wireless network, and power network access. 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 only two steps powering 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 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 towns and remote areas have not yet achieved 5G network coverage. To sum up, based on the analysis of convenience and economy, the 4G network is more suitable for families that need to build a network economically and conveniently.
There are two kinds of devices that share the Internet through the 4G network, LTE CPE and LTE MiFi. LTE CPE belongs to the system integration product. It uses the mobile communication system LTE to provide the back-haul 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 is stronger than MiFi and can be accessed by various mobile terminals such as tablet computers, smartphones, and notebooks at the same time.
After a comprehensive analysis, it is not difficult to see that LTE 4G Router equipment is currently the best choice for us to build our own home network conveniently.
Next, let’s discuss how to choose the right LTE CPE. We choose from the 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.
XMC1841, developed on the ASR1803e chip based on the software architecture of opencpe, is a cost-effective 4G CPE product. Providing users with wireless and wired Internet access.
Its wireless upload 50Mbps and download speeds can reach 150Mbps; the wired speed is 100Mbps.
The internal one-way transmission delay of the user plane is less than 5ms; the transition time of the control plane from the sleep state to the active state is less than 50ms, and the transition time from the resident state to the active state is less than 100ms.
The device supports WiFi 4 (802.11n), its maximum theoretical rate can reach 300Mbps, and 32 devices can connect to the wireless network at the same time.
The device has 5dBi high-gain 4 antennas. The antenna is flattened to increase the effective area of transmission. The unobstructed coverage distance can reach 70 meters. The signal can penetrate 3 walls within 15 meters to keep the WiFi connection stable.
