VM-0217: In a wireless network, the transmission distance is 40 m, concurrent customers 20, an antenna function is 5DB * 2, built-in firewall. Antenna can achieve the purpose of enhancing the wireless signal, it can be understood as an amplifier of the wireless signal. Antennas having different spatial directions different radiation or reception capability, according to different Hefei directional wireless routers, are two directional antennas and an omni-directional. Omnidirectional antenna: In the horizontal plane, and receiving no maximum radiation direction of antenna called omnidirectional antennas. Omnidirectional antenna due to non-directional, so much used in the central station-to-multipoint communications. For example, you want to establish a wireless connection between two adjacent buildings, you can choose this type of antenna. Directional antenna: one or more antenna radiation direction with the maximum reception called directional antenna. Directional antenna energy concentration, the relative gain omnidirectional antenna must be high, suitable for long distance point to point communication, and because Hefei directional wireless 3G router, strong anti-interference ability. When such a district, across several floors need to establish a wireless connection, you can choose this type of antenna. XY-1123: The modular structure can be flexibly configure the router to accommodate the growing business needs of enterprises, non-modular, it can only provide a fixed port. Usually high-end routers for the modular structure, low-end router for non-modular structure. Wireless router's USB port, it can be used as multifunctional server to help you build a network of your own wireless router operating frequency Hefei, when you go out, you can use the office printer, monitor your house via Webcam with colleagues or Friends share files and even download FTP or BT files. USB interface on the market with a wireless router is rare, which Volans of a router is to have a wireless router VE982W USB interface. By 802.11n wireless access point, the route of the transmission rate is three times the 802.11b / g network devices, and supports data rates up to 300Mbps. So wireless access in the room and work everywhere. For example, Greece, Czech Republic, JCG JGR-N605 also supports Wi-Fi Protected Setup (WPS) standard Hefei wireless router hardware, only one button users can establish a secure defense network. If you need a wider range of network coverage, the built-in Wireless Distribution System (WDS) feature lets you clone without adding any cables and lines will be able to expand coverage. VL-X86: 4G Router is a high-speed router networking industry, the full range of compatible 4G / 3.5G / 3G / 2.5G networks, flagship configuration, VPN links, industrial-grade protection, wide temperature design, you can easily set up high-speed, stable wireless transmission network using public wireless LTE network to provide users with long-distance data transmission. 4G router using high-performance industrial-grade 32-bit processors and industrial grade wireless communication module, embedded real-time operating system software support platform, while providing an RS232 (or RS485 / RS422), Ethernet LAN, WAN and Ethernet 1 WIFI interface, can connect serial devices, Ethernet equipment and WIFI equipment to achieve transparent data transmission and routing functionality. 3G wireless router, also known as 3G router, is based on the third generation mobile communication technology router. 3G, third generation mobile communication technology, it is high-speed data transfer rates of up to 14.4Mbps, or a higher data transfer rates via WCDMA, CDMA2000, TD-SCDMA, or and WIMAX networks, of which the first three have been commercialized in China technology. Corresponding to four 3G standards, 3G router is also divided into four types, support a corresponding network. Now the market 3G wireless router are basically three kinds of criteria focused on the former, just change the respective network card can be.
