RadioFrame System
System Description
RFN_3.1 Beta 15
2.1.2.5 802.11b RadioFrame Access Point (RAP)
The 802.11b RadioFrame Access Point (RAP) provides a single RF channel
transceiver supporting the 802.11b (WLAN) standard for wireless data. Each
RAP contains an onboard omnidirectional antenna and provides a coverage area
of approximately 32,000 square feet (nominal 100’ radius cell). Each RAP inserts
into a slot in the RFU.

2.1.2.6 Universal Repeater Unit (URU)
The Universal Repeater Unit (URU) extends the distance between RFS
components, including the NCU and the iSC, from 328’ (100 meters) to 656’ (200
meters). Up to two URUs can extend the distance to 984’ (300 meters). The unit
repeats the Ethernet signal and timing, and can also supply power to an RFU.
2.1.2.7 Ethernet Media Converter
The Ethernet Media Converter (Allied Telesyn model number AT-MC15) is
installed between the NCU and iSC-3. The MC15 converts signals from twisted
pair cable to thinnet cable, and vice versa, providing seamless connection
between two different media with a 10Base-2 BNC connector. An external 12
Vdc power adapter supplies power to the media converter.
2.1.3 Power Plant
The Power Plant consists of two components: a rectifier and battery plant.
