Description :
MikroTik introduces the R52 wireless 802.11a+b+g miniPCI card for multiband high speed applications, it has new Atheros AR5414 chipset with Turbo/Super G (air rate 108Mbps on 802.11g 2.4GHz). R52 works on 2.312-2.499 and 4.920-6.100GHz frequency range.R52 is optimized to work with MikroTik Nstreme protocol to reach extra long distances at a great speed. The Nstreme protocol is MikroTik proprietary wireless protocol created to overcome speed and distance limitations of IEEE 802.11 standards and to extend point-to-point and point-to-multi point wireless link performance. Nstreme2 works with a pair of wireless cards ? one for transmitting data and one for receiving.
