60. Capacity Planning For maximum capacity we need channels Use
20 MHz channels not 40 MHz - more channels available Example of 20
trailers in one area: ~80 Mbps of TCP good put out to a several
hundred yards ~80 / 20 = Four Trailers per channel = ~20 Mbps per
trailer Node to node contention factors Consider one portal and
four remote trailers = 5 nodes The 20 Mbps per trailer now drops
20% = ~70 Mbps At 10 nodes per channel expected throughput = ~60

mistakes you should be sure to avoid!CONFIDENTIAL Copyright 2013.

63. Improperly Aimed Omni AntennasOmni antennas MUST be mounted
perpendicular to the ground.CONFIDENTIAL Copyright 2013. Aruba
Networks, Inc. All rights reservedOmnis are NOT yagis (or magic
wands!) You do NOT point them at the target. 63#airheadsconf
64. Connecting Only 1 Antenna The previous photos also show
only 1 antenna connected to the radio. Aruba regularly is asked by
customers whether it is really necessary to hook up both antennas.
Especially when upgrading old SISO gear to MIMO gear. MIMO systems
are designed to have 2 (or more) active radio chains for both TX
and RX. TX power is cut in half by not connecting an antenna on the
2nd radio chain. This reduces range by 30% and coverage area by
50%. CONFIDENTIAL Copyright 2013. Aruba Networks, Inc. All rights
reserved64#airheadsconf
65. Correct Omni Antenna Installation Omnis must be installed
perpendicular to the ground. Both antenna chains MUST have an
antenna connected. For max performance you MUST use one H-pol and
one V-pol omni antenna. These are sold in pairs by Aruba.
CONFIDENTIAL Copyright 2013. Aruba Networks, Inc. All rights
reserved65#airheadsconf
66. Improperly Aimed Sector Antennas The example on the left
has the antenna aiming straight at the post, blocking the signal!
The example on the right has the antenna aimed at the sky instead
of the ground where clients are. CONFIDENTIAL Copyright 2013. Aruba
Networks, Inc. All rights reserved66#airheadsconf
67. Bending / Damaging RF Cable Many cabling companies do not
have experience with low-loss RF cable such as LMR or Heliax This
installer bent the cable at 45 degrees at a building penetration.
ANY damage to the geometry of a coaxial cable reduces its
performance and increases loss. CONFIDENTIAL Copyright 2013. Aruba
Networks, Inc. All rights reserved67#airheadsconf
68. Improper Antenna SeparationOmni antennas should not be
placed directly against walls. This results in adverse changes to
the pattern, as well as wasted signal absorbed into the
structure.CONFIDENTIAL Copyright 2013. Aruba Networks, Inc. All
rights reserved68When co-locating multiple antennas in an array,
minimum horizontal and vertical separation distances MUST be
computed to avoid having adjacent-channel interference take out all
of the links #airheadsconf
69. Water Ingress Antenna radomes are not usually sealed. They
have holes at the bottom designed to vent condensation and other
water accumulation. NEVER face the weep holes straight up the
antenna will fill with water the first time it rains! NEVER face a
panel antenna straight down for the same reason (unless it is
designed for this such as the AP-ANT-90) CONFIDENTIAL Copyright
