  7. 7. TDMA Spread Spectrum Feature 7 To overcome issues with offaxis emissions, the HX System supports spreading of the TDMA channel by two times and four times the nominal channel bandwidth. A 256 ksps TDMA channel with a nominal channel spacing of 320 kHz can be spread to either 640 kHz (2x spreading) or 1280 kHz (4 x spreading). This feature enables the use of very small antennas as it mitigates adjacent satellite interference. BW = Signal bandwidth before spreading BW’ = Signal bandwidth after spreading BW BW’ Power Density Frequency
  8. 8. TDMA Spread Spectrum Feature With Spread-Spectrum (SS) and depending on the spreading factor used is possible to transmit a C/N less then zero, what means the carrier can be inside the noise. Power Frequency Regular Carrier (RC) Spread-spectrum (SS)Noise
  9. 9. HX200 Satellite Broadband Router Key Features HX200 • DVB-S2 ACM – QPSK, 8PSK, 16APSK • TDMA/FDMA Turbocode Inroutes – Up to 9,8 Mbps • IF Interfaces – Support for either HNS Saturated ODU or L-band BUC – 10 MHz Interface (Can Lock to or Supply a 10MHz Reference) • Communications Interfaces – Two LAN Ports – Autosensing 10/100 BaseT – Each Fully Configurable • Multi-band Support – Ku, C / Ext. C, Ka – Sufficient Internal Power for 4W Ku or 5W C-Band BUC – 48VDC Port for External Power Supply for Higher Power BUCs • Advanced Features – Inroute Spreading x2 and x4 (Optional) – Mobile Antenna Interface (NMEA protocol with DB9 interface)
