Newtec MDM3300 VSAT IP Satellite Modem

MDM3300 IP Modem

The MDM3300 Satellite Modem is a 2-way (transmit and receive), high throughput platform that supports a wide range of IP Services like internet access, VoIP, enterprise connectivity, backbones for backhauling, contribution and multicasting services. Its ease of installation and high performance modulation techniques enable network operators to offer various bandwidth intensive services in a cost effective way.

VSAT Return Link Technology

The modem supports three return access technologies with the Newtec Dialog Platform: MF-TDMA, SCPC and the new patent
pending Mx-DMA (Cross-Dimensional Multiple Access). Mx-DMA incorporates MF-TDMA flexibility and on-demand variable bandwidth allocation at SCPC efficiency.

MF-TDMA satellite return technologies are typically targeting applications with highly overbooked and bursty traffic services, such
as Internet access for consumers, SME, B2B and SCADA. SCPC on the other hand has more applicability in high data and video rate return links. In between there is a large amount of applications with low to medium overbooked services and important throughput rates up to 21 Mbps where Mx-DMA comes into the game.

The modem combines different access technologies with different coding and modulation to match different application requirements. The 4CPM (Quaternary Continuous Phase Modulation) is ideal for low rate bursty traffic and HRC (High Res Coding) will optimize low to medium rate traffic. The high granularity of modcod choices in HRC provides the best modulation and coding for each link condition while the use of short block codes minimizes latency over satellite. For high rate traffic the MDM3300 modem supports S2 return technologies in SCPC.

High Broadband Data Rates

For a true broadband experience at minimal bandwidth consumption, the modem incorporates IP traffic enhancement software for TCP acceleration, pre-fetching, compression and encryption. Traffic can be classified in seven different QoS classes based on IP traffic characteristics (protocol types, source/destination address). Traffic in a specific class is given priority to match the Service Level Agreements.

Terminal Configurations

The Newtec MDM3300 modem is offered seperately or in combination with the ODU Portfolio- a set of different VSAT antenna sizes and BUC
