Maximum Data Rate
– Displays the current maximum data rate, and allows entry of a new
value for the maximum data rate.
BreezeACCESS
units operate at 1 Mbps, 2 Mbps or 3 Mbps. Under certain conditions
(compatibility reasons or range/speed trade-off), you may decide to limit the use of higher
rates. If the quality of the link is not good enough, it is recommended to decrease the value of
these parameters (the higher the date rate, the higher the error rate). Otherwise, there is a high
probability that the unit will have to retransmit many frames several times before temporarily
reducing the data rate. A high number of retransmissions reduces the overall throughput for
the selected SU as well as for all the other SUs served by the same AU.
The link quality can be estimated based on the RSSI measurement using the Continuous Link
Quality Display in the SU. If the measured RSSI is less than a certain threshold, it is
recommended to decrease the Maximum Data Rate of the SU in accordance with the following
table:
Recommended Maximum Data Rate 3Mbps 2Mbps 1Mbps
BreezeACCESS MMDS SU-I/ID RSSI>65 53<RSSI<65 RSSI<53
The default value is 3 Mbps. Allowed values are 1, 2 or 3 Mbps.
The AU learns the Maximum Data Rate used by each SU during the association process, and
uses this rate for transmissions to the specific SU.
•
Flexible Hopping Definition
– Allows adding and removing frequencies to the list of
hopping frequencies; displays the selected hopping frequencies and the current hopping
sequence (based on the previous selections made before the last Reset). The new selections
will come into effect only after the next Reset.
The Flexible Hopping is based on using the standard MMDS 6MHz channels and frequencies.
See Appendix C for a detailed list of the standard channels, as well as the frequency band and
the hopping frequencies for each of these channels.
The Flexible Hopping menu includes the following options, allowing adding/removing
standard MMDS channels or adding/removing discrete standard hopping frequencies.
