An Insight on 4G Wireless Routers

4G Wireless Router is a kind of router with a 4G network module for 4G network. 4G/LTE Router is a wireless gateway for your wireless terminals to access the internet. The 4G router connects to the mobile network with the latest 4G technology and can distribute it in different ways, for example via separate LAN ports or WiFi. Depending on your type of 4G router, you can share the connection with multiple users. The feature of the 4G router is that it has one or two SIM card slots. Some may also have Ethernet port or not. Usually, the 4G wireless router would provide internet connection through WiFi. The LTE WiFi router usually has one SIM card slot, after SIM card plugin, it could be the access point for multiple WiFi-enabled devices, such as PC, laptop, tablets, smart phones etc...

 The 4G Routers with Ethernet ports and SIM card slot are usually 4G Stationary router for home or office use in a small group of people. However, some new 4G pocket WiFi routers are configured with Ethernet port for WAN or LAN or together. These 4G portable WiFi routers with Ethernet port make the gadget could be taken for outdoor activities. It's a new series of the 4G Router. 

In this case, it's also called 4G WiFi Router. Usually, the 4G Router with Ethernet ports are for LAN, and there are 4 LAN ports, sometimes, there may be 1 or 2 ports. The most important is that it must have two external antenna port to support MIMO data transmission. For the LTE router without any LAN ports, we call them 4G LTE Mobile Hotspot, 4G LTE MiFi or 4G Mobile WiFi. Some people call them portable 4G router and they can support at least 5 users to access the internet with peak speed up to 100Mbps. 4GLTEmall.com offers all kinds of 4G Router per customers' preference and their network status. They are all unlocked to make the 4G Routers could roam in different LTE networks. 

A 4G LTE Router usually has an input slot for SIM card, some 4G LTE Routers are with dual SIM card slots. With the data plan of your mobile provider, you can connect to the internet anytime and anywhere. Sometimes, you may need log in the web interface of the LTE router to do some simple settings for the network. After connecting with the wireless 4G network, your 4G LTE Router could provide internet access through LAN port or WiFi. Your devices can get connected to the router and surf.

A 4G Wireless router uses the 4G mobile network and under optimal conditions, it supports 4G network speeds of up to 100 Mbps download and 50 Mbps upload. You, therefore, benefit from mobile broadband connections that are up to ten times faster than the 3G connections. With the LTE network and technology development, the 4G LTE WiFi router could provide much faster speeds than ever. According to the LTE Category, 4G LTE Routers can be divided to LTE Cat.3 router, LTE Cat.4 router, LTE Cat.6 router, LTE Cat.11, Cat.12, Cat.13 router, LTE Cat.16 router and LTE Cat.18 routers. The latest LTE Cat.16 routers and LTE Cat.18 routers are also called LTE Advanced Pro (LTE-A Pro) routers. The 4G LTE Router provide download speeds up to 100Mbps(LTE Cat.3), 150Mbps(LTE Cat.4), 300Mbps(300Mbps), 450Mbps(LTE Cat.9), 600Mbps(LTE Cat.11), or 1Gigabit/s(LTE Advanced Pro) based different LTE technologies.

Previously, WAN support was a service that was only offered to large companies to recover from very serious failures. It was very expensive and only served to recover critical data.

However, today, almost all companies (regardless of their size or field of activity) need to have a failure recovery system to stay connected. Not having WAN support means losing connections between offices, customers and suppliers.

Not only does data transmission fail, but telephony over IP (ToIP) also stops working. For many years, the option that was proposed was to hire a second operator to enjoy a double fixed line installation as a measure of resistance to failures.

However, this solution was very expensive because the wiring of the alternative fixed line had to be installed and the expenses associated with it had to be paid. The real alternative came with the implementation of the 3G mobile network and, later, with the 4G / LTE networks.

Industrial routers have been widely used in the M2M industry in the IoT industry chain, such as smart grid, intelligent transportation, smart home, finance, mobile POS terminals, supply chain automation, industrial automation, intelligent building, fire protection, public safety, environmental protection, weather , digital medical, remote sensing, military, space exploration, agriculture, forestry, water, coal, petrochemical and other fields.

An industrial router is a rugged device used to connect two or more networks to transmit signals only to the desired port. The gateway converts standard Ethernet to Industrial Ethernet protocols, wireless and wired interfaces, or Ethernet and fieldbus communication protocols. Processor performance ranges from 200 to 1500 MIPS, and on-chip memory capacity is typically greater than 256 KB L2 cache. This factory automation unit is rugged and suitable for use in harsh industrial environments where fan cooling is required.

Industrial router WCDMA/HSDPA/HSUPA Router wireless router adopts high-performance 32-bit industrial-grade ARM9 communication processor, with embedded real-time operating system as software support platform, and the system integrates a full range of communication links from logic link layer to application layer. Support static and dynamic routing, PPP server and PPP client, VPN (including PPTP and IPSEC), DHCP server and DHCP client, DDNS, firewall, NAT, DMZ host and other functions. Provide users with secure, high-speed, stable and reliable wireless routing network for routing and forwarding of various protocols. This product has been widely used in finance, water conservancy, environmental protection, electricity, postal, meteorological and other industries.

It has three-layer system protection: On the basis of the original two-level (software protection + CPU built-in watchdog protection, external hardware watchdog protection) system protection, the first-level system monitoring and protection SWP (System Watch Protect) is added, completely solved. Industry "fake online", "fake crash", "downtime" and other difficult issues.

 Perfect VPN: The new router fully supports all the VPN functions in the industry (PPTP+MPPE, IPSEC+L2TP), and solves the problem that the original router cannot support IPSEC due to system problems.

large cache: can provide 32M customer transmission data cache to solve data loss caused by network bottlenecks

High-speed processing CPU: It adopts industrial-grade CPU with more high-speed ARM9 than the original, which can process various protocol data conversions at higher speed and avoid data re-transmission and loss caused by slow CPU processing.

 Memory management MMU: new CPU with memory management MMU, can prevent system instability caused by system memory abnormalities

Real-time operating system: The new system uses real-time operating system RTOS, which can receive and send data more quickly and in real time, avoiding data loss problem.

Complete protocol stack: The new system is loaded with a complete TCP/IP protocol stack, and the network communication performance is excellent.
