Could You Boost the WiFi Signal with Outdoor 4G CPE Router?

When you travel or go to some remote regions, you may be annoyed with the poor signal. Is there any way to get a strong WiFi router signal outdoor in a 4G LTE network? Greatly, the V-SOL outdoor 4G CPE router would be a good choice! Part I. What is the Outdoor 4G CPE Router? V-SOL outdoor 4G CPE router XYC1841 is different from a WiFi-only router, which needs to connect with the fiber-optic network. The 4G CPE WiFi router can receive the operator’s 4G LTE network signals and convert them into broadband and Wi-Fi. You only need to insert

Layer 2 vs Layer 3 Switch, What’s the Difference?

Ethernet switch can access all kinds of terminal devices, set up LANs and achieve direct communications among all equipment. With the development of the network, different switches are put into application. According to the OSI or TCP/IP model, the Layer 2 switch works on the data link layer, while the Layer 3 switch works on the network layer. What’s the detailed difference between the Layer 2 and Layer 3 switch? Part I. What Is Layer 2/Layer 3 Ethernet Switch? Layer 2 switch works on the second layer of the data link layer.

What is 5G CPE: Features, Comparison, and Solution

5G CPE is getting more and more popular with the occurrence of 5G and CPE. But most people are not familiar with it and don’t know its difference from other networking devices such as ONU, WiFi router, mobile WiFi, etc. Some people also don’t know how to get well used. Now in this article, we will get a detailed analysis of the features and solution of 5G CPE. A comparison among different networking methods is also listed. Contents What is 5G CPE? Why choose 5G CPE? VSOL 5G CPE Solution

V-SOL OLT Management Software Introduction: Cloud BS-EMS

In the market, most businesses like Huawei or ZTE offer CS-EMS to manage the OLT (Optical Line Terminal). V-SOL also has this software. However, in order to improve the efficiency and quality of management, V-SOL developed a brand-new system BS-EMS, which would bring operators a better experience and users a securer network. Now let’s start to learn more about BS-EMS! Part I. What is BS-EMS? BS-EMS refers to Element Management System integrated with BS (Browser/Server) architecture. There are five aspects that EMS makes a difference in, which include fault, configuration,

What is TR-069? How’s VSOL TR069-VACS?

Part I. Introduction of TR-069 TR-069 (Technical Report-069) is a communication protocol developed on CWMP (CPE WAN Management Protocol) and the communication link between CPE (Customer Premise Equipment) and ACS (Auto-Configuration Server). With the protocol, CPE can achieve indispensable measures of initialization and operation such as service provision, function setting, the upload and download of files, system detection, etc. Part II. Features of TR-069 Protocol ✔ Automatic configuration of user equipment and dynamic service configuration For ACS, each user’s equipment can mark its model, version, and other info in the protocol. According to

Passive Optical LAN (POL) Overview: Advantages and Solution

In the past, the campus network always adopts traditional cabling methods. With the development of new technology like AR/VR, 4k/8k videos, WiFi 6, etc., the network traffic shoots up and some problems of the network are exposed. For instance, there is no way to manage the network uniformly because there are lots of devices and fault points. It cost a lot to set up a sole network for each of the multiple systems. In this circumstance, POL is created to solve the problems. Part I. What is Passive Optical LAN

What’s the Difference between ONU, Router and Switch?

The Internet has become an indispensable thing in our life. As the carrier of the network, what’s the difference among ONU, router and Switch? How can we distinguish them? In this article, we will answer these questions. At first, let’s get to know what ONU, router and switch are. Part I. What are ONU, router and switch? 1. ONU ONU (Optical Network Unit) is also called optical modem, which is a device similar to the baseband modem. But the difference is ONU accesses optical fiber. It converts the digital signal into

4G vs LTE: Difference Between 4G and LTE!

Both 4G and LTE are a kind of technology in the cellular network. You may see these two terms on your mobile phone. When you want to upgrade your cell carrier, you may feel confused. Here we introduce the difference between 4G and LTE and share something you need to know! Part 1. What’s 4G and 4G LTE? 1. What is 4G? 4G refers to the 4th generation of cellular network technology. It’s optimized based on 3G and performs much excellent. 4G combines WLAN with 3G, making the image transmit

Everything you should know about 2.5 Gigabit Ethernet (2.5GbE)

With the development of 5G/10G and Ultra High Definition Video, the demands for over 1GbE network interface are increasing. Although 10GbE has existed, it requires advanced technology and higher cost. At the moment, 2.5GbE which is between 1GbE and 10GbE is created. More and more devices support a 2.5GbE port. Besides, many laptops no longer provide Ethernet ports so people should use USB to RJ45 to have a 2.5GbE LAN port. Then, what is 2.5GbE exactly and what features can it bring? Below we will explain. Before that, let’s get to know

Comparison: ADSL vs VDSL vs Fiber Optic Internet

The wired access technology develops from digital subscribe line (xDSL) to optical access (PON, Ethernet Optical Access) now. Optical access is occupying the market of broadband access. Why? What’s the difference between ADSL, VDSL and fiber optic Internet? In this article, let’s explore xDSL and optical fiber access networks together!  Part I. What is ADSL, VDSL, and Fiber Optic Internet?  1. ADSL ADSL refers to the Asymmetric Digital Subscriber Line. It’s still a common type of broadband access, which works via standard cabling. The speed of ADSL is not reliable enough, which depends
