Attribute Meaning
Setting this parameter to Flexible causes the radio to operate in
unsynchronized mode. For all other settings, if the AP is in a cluster or is in
range of another AP, then you must set this parameter on all other APs in
the cluster and in range exactly the same. Otherwise, overlapping RF
transmissions will introduce system interference.
Frame Size Configure the frame size for use when in TDD or TDD PTP mode. 2.5 ms
frame size allows for co-location (Synchronization) with PMP 100 series of
radios. It provides lower latency than 5 ms frame with approximately 10%
lower throughput. Frame size is irrelevant when the Downlink/Uplink Ratio
is set to Flexible. Please refer to the
Migration Recommendations
and PMP 100.
Downlink Max Configure the MCS (Modulation and Coding Scheme) rate beyond which
Rate the radio's scheduler should not exceed when transmitting data traffic on
the downlink. This is useful in situations where there is high variance and
unpredictability in the interference present in the environment causing
packet loss. Reducing the max rate to a lower MCS (than the default MCS
15) may help in these situations. Reducing the Downlink Max Rate will
result in reduced sector capacity. Not available when AP is an ePTP Master
or Standard WiFi.
MCS0: The system is configured to use MCS0 rate for all management
Management
messages. This allows for improved link stability and range in high
Traffic Rate
interference environment.
MCS1: The system is configured to use MCS1 rate for all management
messages. This allows for slightly higher sector throughput. This is the
default setting.
Synchronization
Co-location Mode Disabled: The ePMP device is able to synchronize only with other ePMP
Access Points.
Enabled: The ePMP device can be configured to synchronize with PMP 100
series of radios in addition to other ePMP Access Points. Please refer to
the
Guide" for guidance on synchronizing ePMP and PMP 100.
Synchronization GPS: Synchronization timing is received via the AP's connected GPS
Source antenna. Co-located or in-range APs receiving synchronization via GPS or
CMM transmits and receives at the same time, thereby reducing self-
interference.
