Terminology Recap Chapter 21
RADWIN 2000 User Manual Release 2.6.40 21-7
but the numerous combinations of regulation and location preclude specific support.
Release 2.6.40 introduces support for the band 3.3-3.8 GHz as follows:
• FCC part 90 subpart Z and IC RSS-197 supporting 3.650-3.700 GHz
• 3.650 -3.675 GHz in Restricted mode
• Hardware ready for the Unrestricted Mode band operating in all 50 MHz of the
3.650-3.700 GHz band
• IC RSS-192 supporting 3.475 – 3.650 GHz
• ETSI 3.4 -3.7 GHz split into three sub-bands, 3.650-3.675 GHz, 3.475-3.650 GHz and
3.590-3.710 GHz
• RADWIN Universal 3.300-3.800 GHz.
Integrated and connectorized products are available. All of them are multiple band with the
default band being 3.650-3.675 GHz other than the ETSI 3.4 - 3.7 GHz models.
The new products may be operated under 5, 10 and 20 MHz channel bandwidths and are
broadly compatible with the full feature set of RADWIN 2000.
To meet regulatory requirements, a somewhat different procedure is required to set up links
using these bands.
2.5GHz Bands for BRS/EBS
The rationale for these bands and relevant details are described in Chapter 24. The installa-
tion method ids the same as for other licenced FCC bands as described below.
Terminology Recap
• Universal bands refer to RADWIN Universal bands as described above
• 3.X or 3.X GHz refers to the frequency range 3.300 – 3.800GHz
•A 3.X ODU is an ODU pre configured to operate in the 3.X GHz licensed bands
•A 3.X Link in a RADWIN 2000 link using a pair of 3.X ODUs
• High Resolution Bands - Channel minimum step is 250 KHz. Applies to 3.475 -
3.650 GHz IC RSS-192, 3.4 -3.7 GHz ETSI and the 3.3 - 3.8 GHz Universal band.
• Low Resolution Bands - Channel minimum step is 1 MHz. Applies to FCC regula-
tions in the 3.650-3.675 GHz band.
• Inactive Mode - An ODU is powered up, in communication with a managing com-
puter but not transmitting. It is required where regulation does not permit the use of
RADWIN’s default Installation Mode frequency and channel bandwidth. The ODU may
transmit using the licensed or registered band, channel bandwidth and permitted Tx
power.
• Regular Mode - The usual default Installation Mode
Regulatory Considerations for 3.650-3.675 GHz FCC/IC part 90 sub
part Z
Restricted Mode
The band is supported in accordance with 3.650-3.675 FCC/IC part 90 subpart Z:
RADWIN Ltd. conforms to FCC DA 07-4605 (November 14, 2007) FCC-certified with FCC-ID:
Q3KRW2030 and supporting the following equipment requirements:
