The RouterBOARD R52n miniPCI network adapter provides leading 802.11a/b/g/n performance in both 2GHz and 5GHz bands, supporting up to 300Mbps physical data rates and up to 200Mbps of
actual user throughput on both the uplink and downlink. Adding Wireless N to your Wireless device, it provides higher efficiency for everyday activities such as local network file transfers, Internet
browsing, and media streaming.

MikroTik introduces the R5H wireless 802.11a miniPCI card for high speed applications, with up to 320mW output power. It works on 4.920-6.100GHz frequency range and supports Turbo mode for faster transfers.

The card performs best when used with the MikroTik RouterOS.

R5H 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. Nstreme-dual protocol, however is designed to provide real full-duplex communications over wireless with a pair of wireless cards – one for transmitting data and one for receiving.

• Operates in 5 GHz wireless band
• Supports MikroTik NStreme
• Extended distances and higher speeds due to better output signal power
• FCC and CE approval
• Improved commercial grade AR5414A chipset

The very last step is to add an IP address for the MikroTik router to use. Click on ‘IP’ and then ‘Addresses’ and add a new IP address by clicking the ‘+’ button. In the ‘Address’ field, you may type in the IP address of your choice (for this example we will use ‘192.168.10.1/24’ and in the ‘Interface’ field, select ‘bridge1’ Click ‘Apply’ and ‘OK’

That’s it! You have successfully created a WDS network between two or more Access Points. Each Access point in this WDS network will be setup EXACLTY the same way as I have show here. The only thing that will change from Access Point to Access Point is the IP address. In short, all SSID’s, Frequencies, Bands, Bridges, etc will be identical between different Access Points, apart from the IP Address.

MikroTik router can be used as a wireless client. It can be directly connected to a Base Unit. If you are using MikroTik router for ISP, note that you will be sharing the link with the other clients so the bandwidth will be divided. MikroTik router supports Prism II, Atheros, Aironet and RadioLAN interfaces.
