While it would be the model name may draw the wrong conclusion that the 3G modem installed, the manufacturer opted for a solution to connect the modem to the built-in USB port. It should be noted that there is a list of supported modems on the box, and on the website of the manufacturer.
The first LAN port is PoE passive 12 V, so that it can be used as a power source via a network cable to a remote network device whose location can not derive power by other means. The antenna is not fixed, which means that there is always the possibility of drawing the existing antenna cable into place better for the handover signal or setting up a better antenna.

When you approach the graphic web interface, can be seen that the device pretpodešen for the 3G router mode, which means it is designed primarily for use as a 3G modem output to the Internet. Of standards for transmission of data over the mobile network supports 3G, 3.5G, UMTS, EVDO, HSDPA and CDMA-2000. In addition to the mode with 3G modem as the primary access to the Internet, support output over the WAN, with output via 3G WAN as reserves and output via a WAN with 3G as a precaution. Of adjustment to single out one for safety (shared key, WPA2-PSK, WPA2, WPA PSK, WPA, 802.1X and MAC address registration), Virtual Server (open certain ports on PCs), DMZ (open all ports to a particular computer) , URL Filtering, Hotspot way to report clients to go to the Internet, bandwidth control (MAC or IP address), quadruple with the possibility of hiding the SSID and mutual isolation, Ping, Remote Management, VPN Pass Through (IPSec, PPTP and L2TP) DHCP with the possibility of installing 40 fixed IP address, WPS, DDNS, Green AP (can be adjusted for time off and modes with 25, 50 and 75 percent use of force), the choice of a wireless transmitter output power (12-20 dBm) and UPnP. We have an interesting option was a hotspot, that can be used to limit the connection to the Internet on a per user profile. When this option is enabled, the Internet can only be accessed by users who have accounts, because the first approach must enter a username and password in the login form in your browser. The maximum number of orders for the hotspot is 40, and 20 users can be registered simultaneously. It is also important to note that this device has four modes and the router, AP, Client, Bridge, and Repeater.
When setting the device must be particularly careful in setting the parameters 3G modem. Automatic switching from one to another Internet outlet for slower than the professional equipment, but is measured in minutes, which is very satisfactory for home and SOHO conditions. Also commendable is the fact that the loss of primary and secondary transition to link it back to the primary five minutes after the return signal of the primary links in the function. It is very convenient if you use a 3G modem as a secondary connection, since the provider does not offer the flat pack. Switching system has one flaw in the process of restoring the primary connection, and to reboot the modem to return completed, which is most likely done so that the price of the device smaller.
The test also showed very well with a transfer rate of about 7 MB / s, how to send and download data, while the range a bit disappointing because it covers just one floor above and below the floor on which the device was located.
There is a great possibility of using this device in commercial vehicles (trains and buses, for example, as can be powered by AC adapter for car cigarette lighter), and the ability to control the flow in combination with hotspot login method provides great opportunities for resource management in Soho, and even option for providing mini-neighborhoods in the event of a home use. When taking into account the strengths and weaknesses, this device offers many features for a relatively low cost (about 70 euros), and we were really impressed.
