9500 MPR General System Description
2-11
UNLICENSED RADIO
2.6 The JF6-9558H unlicensed radio provides fast deployment of service
with microwave radio. No license and small antennas (no FCC requirements)
allow immediate Turn-Up. After the license is received, the unlicensed radio
can be easily converted to the lower 6 GHz licensed band.
2.7 Refer to 9500 MPR Engineering Support Documentation manual
(PN 3EM23957AA) and see drawing 3EM227840000BJZZA, Equipping
Options Drawing for unlicensed radio configurations and equipping options.
2.8 The JF6-9558H unlicensed radio operates in the 5725-5850
Information, Scientific, and Medical (ISM) band in accordance with FCC Part
15.247. This unlicensed radio, although operating in the same band as a spread
spectrum radio, operates using narrower bandwidths than spread spectrum.
Advantages, disadvantages, and antenna recommendations for the unlicensed
radio follow:
2.9 Advantages:
• Fast installation and Turn-Up
• 18, 26, 37, 53, 114, 160, or 183 Mb/s data payload capacity consisting
of a combination of DS1, DS3, and/or Ethernet traffic
• Field convertible to lower 6 GHz licensed band
• Field expandable to higher capacities.
• Common network management with licensed radios.
• Common spares and training with licensed radios
2.10 Disadvantages:
• Interference from other 5725-5850 ISM band transmissions are
possible
• Operating restrictions
• 5.725 to 5.850 GHz band
• Performance could deteriorate due to interference as the frequency
band becomes congested.
