Managing Ku Band Rain Fades

Managing Ku Band Rain Fades

• Uplink power control (UPC) using a beacon receiver. – Compensates quickly for local rain fade at the hub site.

• ACM (Adaptive Coding and Modulation)– Adjusts FEC rate and modulation dynamically to compensate

for rain fades experienced by each different remote VSAT. • Dynamically assign TDMA carriers with lower FEC and symbol rate

to specific terminals for their TRF bursts during periods of rain fade. Improved link availability

• Better spectrum utilization of both return and mesh links

Features of Our Solutions• Highly Scalable Networks

• Enable any IP application to run reliably and efficiently over satellite.

• Bi-directional TCP/IP communication via satellite for last/first mile applications.

• Supports Enterprise IT Communications strategy.

• Eliminates Satellite bandwidth inefficiencies.

• Network Management.

• Excellent Quality of Service.

• Highest Security Standards - Supports AES and 3DES Encryption

Our Competitive Advantage

The Afcomsat Advantage• Maximize the use of DAMA technology• Reduce total bandwidth requirement• Use smaller antennas• Implement point to point links without the SCPC overheads

of dedicated, under-utilized bandwidth• More Communications Efficiency with new ideas for

economical satellite communications. – DVB-S2, Adaptive Coding and Modulation (ACM), – Dynamic Link Allocation, PCMA, – communication acceleration techniques

• A few of the advanced satellite communication technologies you’ll find in our VSAT products.
