Wireless Router: This is how it Benefits

Wireless Router is an extended product that combines a simple wireless AP and a broadband router. It not only has all the functions of a simple wireless AP, such as supporting DHCP client, supporting VPN, firewall, WEP encryption, etc. It also includes Network Address Translation (NAT), which supports network connection sharing for LAN users. It can realize Internet connection sharing in the home wireless network, and realize wireless shared access of ADSL, Cable modem and community broadband. The wireless router can be directly connected to all Ethernet-connected ADSL MODEM or CABLE MODEM, or can be re-connected through a LAN such as a switch/hub or a broadband router during use. It has built-in simple virtual dialing software, which can store user name and password for dial-up Internet access. It can provide automatic dialing function for dial-up access to the Internet ADSL, CM, etc., without manual dialing or occupying a computer for server use. In addition, wireless routers generally have relatively better security protection.

The 4G router mainly embeds the wireless 4G module in the original router. First, the user uses a tariff card (USIM card) to plug in the 4G router, and through the carrier 4G network WCDMA, TD-SCDMA, etc. dial-up networking, data transmission, Internet access, etc. can be realized. The router has WIFI function to realize shared Internet access. As long as the mobile phone, computer, psp has wireless network card or with WIFI function, it can access the Internet through 4G wireless router, which provides great convenience for wireless local area network sharing 4G wireless network. Some manufacturers also have a wired broadband interface, which can access the Internet without 4G. With 4G wireless routers, broadband connections can be achieved, meeting or exceeding the current ADSL network bandwidth, and becoming very widely used in applications such as the Internet.

Advantage

Intelligent management equipment

The wireless router allows you to enjoy the fast connection to the network life anytime, anywhere under the WIFI security guarantee, never drop the line, intelligent management is equipped with the latest 4G and Wireless-N technology, free to enjoy worry-free network connection, whether it is in an outdoor conference , exhibitions, venues, factories, homes. With a USB 3.0 interface, this hardware allows your desktop and laptop to enjoy a wired or wireless network. Easily download images, high-definition videos, run multimedia software, watch movies or share files with your customers, team members, friends or family.

Always online connection

With a wireless router, you can connect a 3G/HSDPAUSB modem to its built-in USB interface, which allows you to connect to more than 3.5G/HSDPA, 3.75G/HSUPA, HSPA+, UMTS, GDGE, GPRS networks, or GSM networks. The download rate is up to 14.4Mbps. This feature is especially suitable for office environments, where continuous network connectivity is very important.

Multi-functional service

The USB interface of the wireless router, it can be used as a multi-function server to help you build a network of your own.

Gain antenna signal

In a wireless network, an antenna can achieve the purpose of enhancing a wireless signal, which can be understood as an amplifier of a wireless signal. The antenna has different radiation or receiving capabilities in different directions of the space, and depending on the directivity, the antenna has both omnidirectional and directional.

Wireless setting

1. SSID (Service Set Identifier) is an abbreviation of "service group identifier", which is an identifier of a wireless network, and is used to identify the identity of a wireless device found on a specific wireless network. All workstations and access points must use the same SSID to communicate with each other. The SSID is a 32-bit data whose value is case sensitive. It can be the physical location identifier of the wireless LAN, your name, company name, or company name and department, preferred slogan, etc., but if you set it to non-English, garbled characters will appear on some devices, or the connection will not appear. The problem.

2. A channel is also called a "channel", which is a data signal transmission channel that uses a wireless signal as a transmission medium. Wireless broadband routers can operate on many channels. The various wireless network devices located in the vicinity must be on different channels, otherwise signal interference will occur.

Wireless router security settings

Sending and receiving data over a wireless LAN is more likely to be eavesdropped than a wired network. Designing a complete wireless LAN system, encryption and authentication are security factors to consider. The most fundamental purpose of applying encryption technology in WLANs is to enable wireless services to achieve the same level of security as wired services. In response to this goal, the IEEE 802.11 standard uses the WEP (Wired Equivalent Privacy) protocol to set up a special security mechanism for encryption of service flows and authentication of nodes. It is mainly used for the confidentiality of link layer information data in wireless local area networks. WEP uses a symmetric encryption mechanism, and the same key and encryption algorithm are used for data encryption and decryption. WEP uses an encryption key (also known as a WEP key) to encrypt the data portion of each packet exchanged on the 802.11 network. When encryption is enabled, two 802.11 devices must communicate and must have encryption and the same encryption key. WEP encryption is disabled by default, that is, it is not encrypted. Wireless security parameters are optional and generally have three parameters, as follows:

(1) WEP key format: hexadecimal digits; ASCII characters.

(2) WEP encryption level: disable encryption function; 40 (64) bit encryption; 128 bit encryption. The default value is Disable Encryption.

(3) WEP key value: set by the user.

The wireless router works in conjunction with a wireless network card that supports encryption to encrypt and transmit data, making it difficult for others to steal your information. The WEP key can be a set of randomly generated hexadecimal digits or an ASCII character selected by the user. In general, we use the latter and input it manually. Each wireless broadband router and wireless workstation must use the same key to communicate. However, encryption is optional, and most wireless routers default to disable encryption. Encryption can have an impact on transmission efficiency.
