1. Basic Brand Background

There is a Latvia brand called “Mikrotik" in the communications industry, founded in 1995. More than 20-year experience has made him the dominant position in the router and wireless ISP systems market. In order to further deepen the market, has held the exchange meeting in 23 countries. Their equipment mainly includes CCR core router, CRS series routing switch, RB951 941750 series routers and wireless bridge and a series of products.

In order to ensure the stability of our products on the Mikrotik equipment, we have brought the MikroTik CRS226-24Gouter and Mikrotik RB2011UiAS, through a variety of ways to run the device and use our modules, finally got a good certification. Got the recognition and praise from many customers for products applied on the Mikrotik device in many countries in Europe and America.
