VOLUME II, CHAPTER 1, SYSTEM OVERVIEW
ODU 600 for 5.8 GHz ISM Band
ODU 600 supports fixed modulation or adaptive modulation (with RAC 60E).
l License-based upgrades enable transition from Tx standard power to high
power Flexible Power Mode (FPM).
l ODU 600 is supplied with diplexers for Tx high or Tx low working.
l ODU 600 is designed for direct-antenna mounting, but can be remote
mounted using an ODU remote-mount kit.
l Equal-loss and unequal-loss direct-mounting couplers are available for hot-
standby or frequency diversity single antenna operation.
5.8 GHz Unlicensed Band
Eclipse INUs with ODU 600 are compliant with FCC CFR47, Part 15.247, and
Industry Canada RSS-210 Annex 8, on ISM frequency band 5725 to 5850 MHz. Inter-
national use is not supported; the system does not employ DFS and as such cannot
be deployed within Europe or any country where DFS is a regulatory requirement for
protection of radars.
Features and Capabilities:
l Bandwidths 5, 10, 20, 30, or 40 MHz.
l Adaptive or fixed modulation options.
l Supports Ethernet and/or NxDS1 payloads, with air-link capacities to 254
Mbps (40 MHz Ch BW).
l Hot-standby and diversity protection options.
l Output power is limited to 28 dBm at the waveguide port to ensure
compliance with the FCC 1 Watt rule.
l For Tx power and system gain figures, see the Eclipse ODU 600 datasheet.
Operational Limitations and Restrictions
Unlicensed band operation means sharing the air-space with other operators of unli-
censed band links. Interference is possible.
l ODU 600 5.8 GHz operation is 'narrow-band'; it competes/shares spectrum
with other narrow-band links and with spread-spectrum links.
l Performance could deteriorate over time with the introduction of other links in
the same geographical area.
l Antennas must be approved (FCC or Industry Canada) for 5.8 GHz unlicensed
band.
