Radio Parameters
LigoPTP 24 is a good example of latest achievements in modem and transceiver development,
providing both excellent radio parameters (System Gain), due to use of
APSK modulation
and
efficient yet consuming little power Tx/Rx part of the system.
RSL Threshold at BER 10
-6
, 28MHz, 32APSK, 100Mbps:
-77 dBm
.
System Gain with guaranteed max Tx power and Rx sensitivity is
93 dB
.
LigoPTP 24 provided the capability to replace typical 34Mbps PDH radio to
108Mbps
system by
retaining the antenna size/distance
ACM
(Adaptive Coding and Modulation), hitless ACM opens whole lot of new possibilities
depending on network designers strategy
ATCP
, Automatic Transmitter Power Control, for increased deployment density capability.
Very high flexibility
allows configuring the system to various channel bandwidths, modulation
schemes and capacity settings
