Chapter 3. System Overview
• Common 5.8 GHz and L6 RFU supports easy migration from one band to the other
(from unlicensed to licensed and vice-versa).
• RFUs can be retained during migration, but ACU must be replaced (not retuned).
• Extensive protection and diversity options.
• Output power (at 5.8 GHz) is limited to 29 dBm at the antenna port for IRU 600, and
29.5 dBm for IRU 600v2. This is to ensure compliance with the FCC 1 Watt rule.
• For Tx power and system gain figures, see the Eclipse Packet Node ANSI Datasheet.
Operational Limitations and Restrictions
Unlicensed band operation means sharing the air-space with other operators of
unlicensed band links. Interference is possible.
IRU 600 5.8 GHz operation is 'narrow-band'; it competes/shares spectrum with other
narrow-band links and with spread-spectrum links.
Performance could deteriorate over time with the introduction of other links in the
same geographical area.
Antennas must be approved (FCC or Industry Canada) for 5.8 GHz unlicensed band.
