number between 10 and 100 and check to see if the calculated Registration Cycle is
below 1000 usec. Lower the entered number to bring the Cycle below 1000 usec. Higher
numbers give better efficiency. A good starting number is approximately double the
number of subscribers.
Max Distance (km) – Input the distance between the base station and the most distant
subscriber in the sector in km. This parameter is used to allow for sufficient time to
receive responses from subscribers that may be new to the PMP sequence.
Max QoS Level – This represent the maximum Quality of Service levels that will be used
within the sector. The tool sets the priority level within a subscriber for actual data rate
traffic as a result of the desired rate selected by the user. Levels vary from 1 to 18, with
18 being the higher level. Enter a value between 1 and 18 with 18 being the highest
efficiency. A value of 18 is usually entered unless a cap on the Obtained Date Rate
calculation is desired.
Desired CIR (kbps) – Enter the CIR (Committed Rate Information) desired on both the
downlink (base station to subscriber) and uplink (subscriber to base station) direction of
the PMP link for each individual subscriber beginning with subscriber Link ID #4. Enter
as many subscribers as desired up to a maximum of 256.
Burst Rate (Mbps) – Enter the Uncoded Burst Rate that will be used by both the
downlink (base station) and uplink (Subscribers). The uncoded burst rate is a function of
the modulation mode that will be the typical one used for an individual link and can be
taken from the table below:
Modulation FEC Coding Rate Uncoded Burst Rate
(Mbps)
BPSK ½ 6
BPSK ¾ 9
QPSK ½ 12
QPSK ¾ 18
16QAM ½ 24
16QAM ¾ 36
64QAM 2/3 48
64QAM ¾ 54
Distance (km) – Enter the distance between the base station and the individual
subscriber.
PMP Configuration Tool Results
Max. Traffic Latency (us) – Shows the time required for one complete PMP cycle
communicating once with all active subscribers.
Registration Cycle (ms) – Should be less than 1000 usec. If not, lower the number of
frames in the Registration Period. The time the base station spends polling active
