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
