RB2011UAS-2HnD

The RB2011 is a low cost multi port device series, powered by RouterOS, a fully featured routing operating system which has been continuously improved for fifteen years. Dynamic routing, hotspot, firewall, MPLS, VPN, advanced quality of service, load balancing and bonding, real-time configuration and monitoring - just a few of the vast number of features supported by RouterOS.

RouterBOARD 2011UAS-2HnD has most features and interfaces from all our Wireless routers. It’s powered by the new Atheros 600MHz 74K MIPS network processor, has 128MB RAM, five Gigabit LAN ports, five Fast Ethernet LAN ports and SFP cage (SFP module not included!). Also, it features powerful 1000mW dual chain 2.4Ghz 802.11bgn wireless onboard, RJ45 serial port, microUSB port and RouterOS L5 license.

There are two MMCX connectors for adding external antennas, so you can create powerful dual chain wireless backbone, AP or CPE unit.

Tested and recommended to use with MikroTik SFP modules: S-85DLC05D, S-31DLC20D and S-35/53LC20D (not included)

All tests are done with Xena Networks specialized test equipment (XenaBay),and done according to RFC2544 (Xena2544)
Max throughput is determined with 30+ second attempts with 0,1% packet loss tolerance in 64, 512, 1518 byte packet sizes
Values in Italic indicate that max throughput was reached without maxing out CPU, but because board interface configuration was maxed out
Test results show device maximum performance, and are reached using mentioned hardware and software configuration, different configurations most likely will result in lower results
