is a software for wireless, point-to-point data transmission using single 802.11a radio. It may be used with dedicated hardware platforms, eg. RouterBOARD RB411.
Transmission is realized using Time-Division Duplex (TDD) technique. It is an algorithm which ensures no medium access collisions and which precisely controls bandwidth allocation to both link sides. Communication is divided into time windows, which in alternate manner enforce transmission by only one link side at the same time.

- radio frequency selection in range of 4.9GHz - 6.1GHz with 5MHz step
- 4 channel widths: 5Mhz, 10MHz, 20MHz, 40MHz
- automatic selection of modulation, transmit power and radio frame length
- automatic AES-CCMP encryption of transmission
- enforce strict order of Ethernet frames or allow reordering
- interactive WWW interface
- console interface available through SSH protocol
- works as a fully transparent Ethernet bridge
- supports management through VLAN
- STP (IEEE 802.11D) support
- fully translated to English and Polish
RadioOS supports IEEE 802.11a radio modules based on Atheros chipsets. In particular, it can work with:
- AR5414 - eg. Ubiquiti XR5, UB5
- AR5213 - eg. Wistron CM9, Ubiquiti SR5
Link performance is highly dependent on quality of antenna. It is recommended to use products of renown vendors, like MTI, Mars, etc.
