MikroTik introduces the R52H wireless 802.11a+b+g miniPCI card for multiband
high speed
applications, with up to 350mW output power. It works on 2.192-2.539 and
4.920-6.100GHz
frequency range and supports Turbo mode for faster transfers. The card performs
best
when coupled with the MikroTik RouterOS.
➔ Turbo, 802.11a, 802.11b and 802.11g IN ONE
➔ Operates in both 2.4 GHz and 5 GHz wireless bands
➔ Support MikroTik Nstreme
➔ Extended distances and higher speeds due to better output signal power
➔ FCC and CE approval
R52H 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. The new
Nstreme-dual
protocol designed to provide real full-duplex communications over wireless with
a pair of
wireless cards – one for transmitting data and one for receiving.
