Product Manual
P30 is a self-developed satellite modem with completely independent intellectual property rights based on CDMA/TDMA system. It is 19 inch in one unit of standard rack. It uses L band interface connecting to LNB and BUC and supports 64Mbps rate of transmitting effective information at maximum. It also synchronizes V.35 and 10/100M BASE-T interface. E1 and RS232 interface also can be used as need.span>
P30 supports point to point, mesh network, star network and other network mode. It widely applies to safety supervision, fire protection, meteorology, maritime, military, expedition, oil exploration, and all kinds of emergency communication. It is a SCPC modem supporting network management. It has spread spectrum function and can effectively reduce the power spectral density.。
System Advantages
● Support multiple networking ways, such as SCPC, TMD/TMDA and TDM/TDMA MESH;;
● High speed modem, data rate: 64Kbps-64Mbps;
● TDMA system efficiency: 90%;
● Customized input/output frequency, default frequency: 950-2150MHz. Customers could choose 70/140MHz intermediate frequency interface or C-band interface.
● Use IP interface; E1, RS232 and V.35interface could be expanded;
● Spread spectrum function: decrease power spectral density effectively, suitable for small aperture terminals;
● Support remote monitoring and management.
