When we discuss the topic of 4G LTE, we still cannot ignore the fact that from the perspective of global network communication, people in many countries still face the problem of expensive cost and slow download speed of 4G network traffic. In this case, how to use network resources reasonably is a question worth studying.
The emergence of 4G LTE routers has solved some people’s needs for portable Internet access and multi-machine wireless network sharing. Here, we will discuss the 4G LTE wireless router.
The development of this product is closely related to the price of the network service provider ’s traffic on the 4G network. As the rate drops, the product may slowly withdraw from the market, but it is certain that it will not be eliminated because it still Can meet the needs of some specific groups, and in the past few years it has played a very important role in many wireless products.
1. The realization principle of 4G LTE router
First, the LTE wireless gateway accesses the 4G network, then the 4G network provides the user with a high-speed wireless backhaul link, and the LTE-WiFi downlink provides the user with a WiFi coverage environment. Finally, the user logs in to the operator ’s network terminal device, such as a smartphone, in the following manner Or iPad.
2. Several application scenarios of 4G LTE router
Generally speaking, this product can be used almost in the place where 4G network is deployed, you only need to select the appropriate type according to actual needs. Here, I list some common usages of the product for your reference.
1> Indoor LTE-WiFi coverage
Deploy LTE-WiFi wireless gateway devices in indoor hotspots and transmit them back through the TDD-LTE / FDD-LTE network to meet the needs of WiFi users for indoor wireless access. The device is usually used in airports, train stations, bus stations, cafes, tea houses, hotels and other hot spots in the city.
2> Outdoor LTE-WiFi coverage
Deploy LTE-WiFi wireless gateway equipment in outdoor hotspots to provide backhaul and data services to WiFi users through 4G networks. The outdoor LTE-WiFi wireless access gateway equipment is installed on the top of the building, and the surrounding environment covers WiFi. It is usually used in sports venues, city squares, industrial parks, city parks, residential areas, tourist attractions, beaches and other areas.
3> LTE-WiFi wireless coverage
Deploy LTE-WiFi wireless gateway devices for urban buses and private cars, and provide backhaul through TDD-LTE / FDD-LTE networks to provide data services for in-vehicle WiFi users, and also bring users LTE high bandwidth advantages . It is used in private cars, buses, coaches, subways, and light rail to meet passengers’ needs for wireless Internet access.
3. Three product forms of 4G LTE router
1> The first is to provide services through the USB interface on the router. You only need to plug the 4G USB modem into the USB interface to achieve Internet access for multiple computers by sharing 4G data services. Particularly suitable for users who do not have easy access to fixed broadband or need to share a mobile network.
2> The second one is a 4G Wireless router with a SIM card slot but no USB interface. It usually also integrates an LCD screen. Just insert the SIM card and do some simple configuration to achieve WiFi Internet access.
3> The third is to support ordinary broadband access by providing a WAN interface, such as supporting traditional DSL and Cable broadband access. It also has excellent compatibility, making it easy to share Internet access among multiple users. In addition to supporting multiple access methods, it also supports a variety of practical functions, such as support for WDS functions, which can wirelessly bridge several wireless routers to expand wireless network coverage. , You can effectively control the download rate of each client through the QoS bandwidth control function.
4. Main technical indicators of 4G LTE wireless router
In my years of experience using this product, what do I value more? Here I may list some key points, I hope it can provide you with a reference.
Physical size, most of these products are small, mainly for portability, it is best to be directly installed in your pocket.
Endurance, different brands of products, provide different endurance, general requirements not only to meet the 24-hour Internet demand, but also best meet the needs of mobile phone charging.
Traffic, according to the data plan of the local operator, different plans correspond to different prices
Supported applications, including statistical information on SMS services, network traffic usage, network speed, power consumption and other parameters,
According to the actual use of field analysis, there are too many factors that affect the quality of the wireless network.
Download and upload speeds. The general download speed of such products is 100Mbps and the upload speed is 50Mbps.
5. Defects of 4G LTE wireless router
1> The coverage is limited, because the use of built-in antenna technology, the radiation of wireless signals will be weaker than traditional wifi routers.
2> Excessive dependence on the network traffic rate of the operator.
