Rerun link tests.
Uplink and
downlink are both
≥60% Efficiency.
Optionally, re-aim SM, add a
reflector, or otherwise mitigate
interference. In any case, continue
2X operation up and down.
Results are
inconsistent and
range from 20% to
80% Efficiency.

Optionally, re-aim SM, add a

Rerun link tests.
No substantial
improvement with
consistency is
seen.
On the General tab of the SM,
disable 2X operation. Then rerun
link tests.
Rerun link tests.
Uplink and
downlink are both
≥90% Efficiency.
Continue 1X operation up and
down.
NOTES:
1. Or check Session Status page of the Advantage AP, where a sum of greater than 7,000,000 bps for the
up- and downlink indicates 2X operation up and down (for 2.4- or 5.x-GHz modules.
2. For throughput to the SM, this is equivalent to 120% Efficiency in 1X operation, with less capacity used at
the AP.
3. This link is problematic.
12.5 CONSIDERINGFREQUENCYBANDALTERNATIVES
For 5.2-, 5.4-, and 5.7-GHz modules, 20-MHz wide channels are centered every 5 MHz.
For 2.4-GHz modules, 20-MHz wide channels are centered every 2.5 MHz. For Cyclone
OFDM, the operator can configure center channel frequencies of the 10 MHz channels
with a granularity of 0.5 MHz.This allows the operator to customize the channel layout for
interoperability where other Cyclone equipment is collocated.
Cross-band deployment of APs and BH is the recommended alternative (for example,
a 5.2-GHz AP collocated with 5.7-GHz BH).
IMPORTANT!
In all cases, channel center separation between collocated Cyclone FSK
modules should be at least 20 MHz for 1X operation and 25 MHz for 2X. For
Cyclone OFDM, channel center separation between collocated modules should
be at least XX MHz for 1X operation, XX for 2 X operation, and XX for 3X
operation.
