Task 6: Configuring radio parameters
Attribute Meaning
Broadcast
Repeat Count
The default is 2 repeats (in addition to the original broadcast packet,
for a total of 3 packets sent for every one needed), and is settable to
1 or 0 repeats (2 or 1 packets for every broadcast).
ARQ (Automatic Repeat reQuest) is not present in downlink
broadcast packets, since it can cause unnecessary uplink traffic from
every SM for each broadcast packet. For successful transport without
ARQ, the AP repeats downlink broadcast packets. The SMs filter out
all repeated broadcast packets and, thus, do not transport further.
The default of 2 repeats is optimum for typical uses of the network as
an internet access system. In applications with heavy download
broadcast such as video distribution, overall throughput is
significantly improved by setting the repeat count to 1 or 0. This
avoids flooding the downlink with repeat broadcast packets.
Transmitter
Output Power
This value represents the combined power of the AP’s two
transmitters.
Nations and regions may regulate transmitter output power. For
example
• 5 GHz modules are available as connectorized radios, which
require the operator to adjust power to ensure regulatory
compliance.
The professional installer of the equipment has the responsibility to
• maintain awareness of applicable regulations.
• calculate the permissible transmitter output power for the
module.
• confirm that the initial power setting is compliant with national or
regional regulations.
• confirm that the power setting is compliant following any reset of
the module to factory defaults.
External Gain
This value needs to correspond to the published gain of the antenna
used to ensure the radio will meet regulatory requirements.
SM Receive
Target Level
Each SM’s Transmitter Output Power is automatically set by the AP.
The AP monitors the received power from each SM, and adjusts each
SM’s Transmitter Output Power so that the received power at the AP
from that SM is not greater what is set in this field. This value
represents the transmitted and received power (combined power)
perceived on the SM.
