Overview
CHAPTER 2. OVERVIEW
General Information
The DIR-853 device is a wireless dual band gigabit router with 3G/LTE support. It provides a fast
and simple way to create a wireless and wired network at home or in an office.
The router is equipped with a USB port for connecting a USB modem
1
, which can be used to
establish connection to the Internet. In addition, to the USB port of the router you can connect a
USB storage device, which will be used as a network drive, or a printer.
Also you are able to connect the wireless router DIR-853 to a cable or DSL modem or to a private
Ethernet line and use a high-speed Internet connection to successfully fulfill a wide range of
professional tasks. The built-in 4-port switch enables you to connect Ethernet-enabled computers,
game consoles, and other devices to your network.
Using the DIR-853 device, you are able to quickly create a high-speed wireless network at home or
in your office, which lets computers and mobile devices access the Internet virtually anywhere
(within the operational range of your wireless network). Simultaneous activity of 2.4GHz band and
5GHz band allows performing a wide range of tasks. The router can operate as a base station for
connecting wireless devices of the standards 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac (at
the wireless connection rate up to 1300Mbps
2
).
The router supports multiple functions for the wireless interface: several security standards (WEP,
WPA/WPA2), MAC address filtering, WPS, WMM.
In addition, the device is equipped with a button for switching the Wi-Fi network off/on. If needed,
for example, when you leave home, you can easily switch the router’s WLAN by pressing the
button, and devices connected to the LAN ports of the router will stay online.
Multi-user MIMO technology allows to distribute the router's resources to let multiple wireless
clients use the Wi-Fi network efficiently, keeping high rates for HD media streaming, lag-free
gaming, and fast transfer of large files.
Transmit Beamforming technology allows to flexibly change the antennas' radiation pattern and to
redistribute the signal directly to wireless devices connected to the router.
Smart adjustment of Wi-Fi clients is useful for networks based on several D-Link access points or
routers – when the smart adjustment function is configured on each of them, a client always
connects to the access point (router) with the highest signal level.
Support of guest Wi-Fi network allows you to create a separate wireless network with individual
security settings and maximum rate limitation. Devices connected to the guest network will be able
to access the Internet, but will be isolated from the devices and resources of the router's LAN.
The wireless router DIR-853 includes a built-in firewall. The advanced security functions minimize
threats of hacker attacks, prevent unwanted intrusions to your network, and block access to
unwanted websites for users of your LAN.
In addition, the router supports IPsec and allows to create secure VPN tunnels.
